Acute mesenteric ischemia: The what, why, and when?
Edwin Stephen, Ziyab Khan Sarfaraz, Ibrahim Abdelhedy, Khalifa Al Wahaibi
January-March 2016, 3(1):24-28
DOI:10.4103/0972-0820.180211  
Acute mesenteric ischemia (AMI) is a complex clinical problem with a high mortality. The mortality associated with AMI has declined steadily over the last three decades. This is due to higher index of suspicion among clinicians, advances in radiographic diagnostic modalities, aggressive surgical approach, endovascular intervention, nutritional supplementation, and better perioperative care. Early diagnosis and prompt, effective treatment are essential to improve the clinical outcome. This article reviews the etiopathogenesis, clinical features, management, and outcomes of AMI.

Intravenous infusion of prostaglandin E1 therapy in extremity ischemia
Pinjala Ramakrishna
April-June 2017, 4(2):38-42
DOI:10.4103/ijves.ijves_16_17  
Prostaglandins are potent vasoactive agents with wide variety of other actions - vasodilatation, fibrinolysis and inhibition of platelet aggregation. PGE1 was the agent used since 1973 for cardiovascular diseases, mainly in patients with advanced PVD. PGE1 intra venous infusion has shown to be beneficial in limb threatening ischemia, especially when reconstructive procedures are not feasible and also as an adjunct when there is residual ischemia after revascularization. The review of literature and the use of PGE1 in CLI is presented here along with our experience in NIMS.

Management for Carotid Body Tumors: A Single Center Experience
Devender Singh, R Jaydip, Rajani
October-Decenber 2014, 1(1):8-11
DOI:10.4103/0972-0820.142356  
Introduction: The carotid body tumor is a rare neoplasm that has generated much literature over the last century, and for which continued controversy exists regarding natural history, biologic behavior, proper technique of excision, and the risk of morbidity and mortality. Methods: The present study reviewed a 7-year experience of managing carotid body paraganglioma between 2007 and 2013. There were 10 consecutive patients aged between 18 and 50 years, and median follow-up was 5-year. Preoperative information was derived from spiral computed tomography (CT) scanning, magnetic resonance imaging, color Doppler imaging (CDI), and four-vessel digital subtraction arteriography. Results: In five patients, the tumor excision was attempted before they were referred to our tertiary care hospital. Two patients had bilateral tumors. Four patients had preoperative embolization, and blood loss was minimal, and excision was relatively easier in them. There was difficulty in deglutition (nasal and laryngeal regurgitation) in three patients with large tumors. Conclusion: Surgical planning and prediction of peri-operative complications can be obtained by digital subtraction angiography, spiral CT angiography, and CDI. The peri-operative blood loss can be reduced by preoperative embolisation.

DOI:10.4103/0972-0820.152825  
Introduction: Complete obstruction of the abdominal aorta at the renal artery level is a difficult surgical problem. Methods: From August 2010 to January 2014, descending thoracic aorta to femoral artery bypass grafting was used to re-vascularize the lower limbs of the patients in our center. We analysedd our results Results: Primary indication was lack of a suitable site for aortic clamping. Average duration of surgery was 2.5-4.5 h, and blood loss was 100-400 mL. We use BARD®, IMPRA® expanded polytetrafluoroethylene vascular graft for thoraco-bifemoral bypass surgery. There was one mortality due to myocardial infarction. Major morbidities were graft occlusion in one patient that was managed by embolectomy and ascites in another patient, managed conservatively. Conclusion: Thoracic aorta to femoral artery bypass is a simple extra anatomic bypass technique, which can be used in case of difficulty to use abdominal aorta for lower limb re-vascularization.

Elamaran Elamurugan, R Hemachandar
April-June 2016, 3(2):49-52
DOI:10.4103/0972-0820.183645  
Purpose: An option for patients who are unsuitable for radiocephalic fistula is brachiocephalic (BC) fistula. In such patients, we exploited the venous interconnections in the cubital fossa for median antecubital vein (MAV)-BC arteriovenous fistula (AVF) creation. In this article, we describe our experience in the creation of such technical variant of the BC fistula AVF, its success, and associated complications. Materials and Methods: A retrospective review of such AVF created between September 2014 and August 2015 was done. The data collected included demographics, comorbidities, basic disease, operative details, patency, complications, and mortality. Results: A total of 68 vascular access surgeries were done which included 26 (38.2%) BC AVF using the MAV. The mean cephalic vein diameter and mean flow rate were 7.18 mm and 1415 ml/min, respectively, 2 months after fistula creation. The primary and secondary failure rates were 3.87% and 7.69%, respectively. Complications included aneurysm (7.69%), edema (19.23%), hematoma (11.53%), and wound infection (2.5%). Conclusion: Using reverse flow in the MAV is a safe and simple way to perform BC AVF before brachiobasilic AVF and grafts.

DOI:10.4103/0972-0820.142362  
Spontaneous vascular thrombosis may occur after a short climb or prolonged stay at high altitude (HA). Both venous and arterial thrombosis has been reported in the literature and cause significant morbidity and mortality. Diagnosis is often difficult; treatment delayed and postthrombotic sequelae disabling. Experimental evidence is limited and trials to prove thrombogenecity of HA are technically challenging to conduct. A greater understanding and awareness of its varied presentations and management is required by all those engaged in treating such patients.

Amila Weerasekera, Raghvinder Pal Singh Gambhir
July-September 2017, 4(3):85-91
DOI:10.4103/ijves.ijves_26_17  
Pre- or post-intervention, vascular surgical patients are expected to be on one or more antithrombotic agents. Antithrombotics have played a key role in reducing cardiovascular mortality in vascular patients. There are wide variations in the practice of prescribing antithrombotic agents in vascular services. Evidence-based current practice guidelines are often not strictly followed which puts some of these patients at increased risk of bleeding complications. This paper looks at the current practice guidelines on antithrombotics.

Risk Factors and Saphenofemoral Junction in Varicose Veins
Kshitij Manerikar, Arjinder Pal Singh Bawa, Abhilash Kumar Pithwa, Gurjit Singh, Harshwardhan Shrotri, Somnath Gooptu
October-December 2015, 2(4):134-138
DOI:10.4103/0972-0820.180110  
Introduction: Varicose veins (VVs) are dilated, tortuous, subcutaneous veins. It is common condition causing substantial morbidity. Prevalence of VVs ranges between 5% and 30% in the adult population. Surgery is one of the common modality of its treatment. A complete knowledge about anatomical variation at saphenofemoral junction (SFJ) and variations in tributaries of great saphenous vein (GSV) is important while dealing with such patients effectively. It will help in reducing chances of recurrences and complications. Methods: A prospective non-randomized study of fifty patients was carried out in our hospital between May 2014 and May 2015. Diagnosis was established by clinical examination and supplemented with venous duplex ultrasound study. Patients were subjected to trendelenburg's operation, stripping of GSV with hook phlebectomy of affected perforators. Results: A total of fifty patients were studied in this study, in which tobacco chewing was the most common associated risk factor with primary VVs, and it was observed in 46% of patients. Amongst them, twenty patients were obese with body mass index of more than 25 kg/m 2 . Location of SFJ was a mean of 2.24 ± 0.55 cm inferior and 3.77 ± 0.61 cm lateral to the pubic tubercle on duplex ultrasound and 2.35 ± 0.42 cm inferior and 3.73 ± 0.58 cm lateral intraoperatively, both of which had nonsignificant P value. The number of tributaries varied from 2 to 6 at the first 5 cm from SFJ. There were two and six tributaries in one patient each whereas three tributaries were observed in 42% patients. The most frequent consistent branch was a superficial inferior epigastric vein, seen in 98% of patients. The least frequent branch was posterior accessory saphenous vein, seen only in 2% of patients. The external pudendal artery was crossing SFJ anteriorly in 38% and posteriorly in 56%, and it was not identified in remaining 4% patients. Conclusion: Our study showed the nonsignificant difference in Duplex ultrasound and intraoperative finding of SFJ location with respect to pubic tubercle; hence, one can plan a precise incision with the help of duplex ultrasound marking preoperatively. One must look for all tributaries for ligation which will prevent recurrence of varicose vein as variation in numbers and location of tributaries was remarkable in our study.

Introduction: This was a retrospective study of the experience with extremity vascular trauma at a tertiary level referral center in North India. The objective of this study was to analyze the cause of injury, surgical approach, outcome, and complications in patients with vascular trauma operated from 2003 to 2013. Materials and Methods: A retrospective analysis of records of patients who were operated for peripheral vascular injuries in the last 10 years (November 2003 to November 2013) was done. Diagnosis was made by physical examination and hand Doppler alone or in combination with computed tomography angiography. There were 3948 patients; primary vascular repair was carried out where possible; if not possible an interposition vein graft was placed. Patients with isolated venous trauma or unsalvageable lower extremity injury requiring primary amputation were excluded from the study. Results: Of 3948 patients, 3347 were male (84.78%), and 601 were females (15.22%); their ages range was 5-80 years. Mean duration of the presentation was 11 h after the injury. Road traffic accidents were the most common cause of injury: 67% in those with penetrating trauma and 58% in those with blunt trauma. The incidence of concomitant orthopedic injuries was very high in our patients (73.6%). The most common injured artery was the brachial artery (36.4%), followed by the popliteal (30.4%) and femoral artery (21.7%). Primary repair was performed in 58.3%, interposition vein grafts in 41.4%. Majority of patients had a good outcome-78% had functional, viable limbs. About 13% had a nonfunctional, but viable limb; the secondary amputation rate was 9%. Conclusion: Early diagnosis and treatment of vascular injuries is crucial for saving the patient's limb and life. Our study is the largest study from a single center in India/South West Asia: Increased awareness is required to ensure that patients identified to have a vascular injury are transferred to a specialist vascular surgery center at the earliest. Vascular injuries require immediate localization and surgical intervention. Prompt and decisive management maximizes patient survival and limb salvage- and as we demonstrate, this is possible even in patients with delayed presentation or when early ischemic changes are present. Protocols must be established in the management of associated injuries to avoid delay.

DOI:10.4103/0972-0820.166933  
Objective: To study the outcomes of the ultrasound guided foam sclerotherapy (UGFS) treatment for superficial venous insufficiency. Materials and Methods: Selected patients with varicose veins were treated with UGFS using sodium tetradecyl sulfate as sclerosant and followed up to 1-year. Total 148 legs in 123 patients, 98 unilateral limbs, and 25 bilateral limbs were treated by this method. Results: Out of 148 legs saphenofemoral junction (SFJ) incompetence was found in 42 and sapheno-popliteal junction (SPJ) incompetence in 49, perforator's incompetence in 11, while combination of SFJ and perforators and SPJ and perforators in 16 and 7, respectively. Great saphenous vein varicosity was found in 58, short saphenous vein in 56 and others 34. Twenty-four limbs had recurrent varicose veins previously treated by other modalities, and 124 limbs had primary varicose veins. Fifty-two limbs were treated for complicated varicose veins (CEAP 4-6) and 96 limbs for uncomplicated varicose veins (CEAP 2-3). Early outcome was 100% success rate. No recurrences were noted at 1-year follow-up. Early complications were: Superficial skin necrosis in 4 legs (2.70%), pain at injection sites in 21 legs (14.18%), superficial thrombophlebitis in injected vein in 21 legs (14.18%), bruising in 18 legs (12.16%), superficial vein thrombosis in 10 legs (6.75%), and skin staining around injected veins in 13 legs (8.78%). Conclusion: UGFS is a safe, good, and effective treatment modality of treatment for patients with varicose veins and found to be associated with significantly less bruising and pain.

Indrani Sen, Sunil Agarwal
January-March 2015, 2(1):25-27
DOI:10.4103/0972-0820.152830  
Distal DVT comprises of thrombosis of the infra-popliteal veins. This subgroup lacks standard clinical practice guidelines due to differing viewpoints on the etiopathogenesis, natural history, treatment and outcome. Most originate in the calf and resolve spontaneously. Detection also depends on the diagnostic modality used with invasive methods like venography yielding a higher incidence. It is seen more often in patients with transient risk factors (recent surgery, recent plaster immobilization, recent travel). Thrombus propagation/ extension can occur in 25%- 36% with symptomatic PE in 6-36%. Recurrence occurs in 4-29 % , chronic venous insufficiency( post thrombotic syndrome) can occur in 4- 23 %. The overall event rate (death, PE, extension, bleeding) is about 5% which can be further lowered with treatment

DOI:10.4103/0972-0820.186726  
Carotid body tumors (CBTs) are rare benign tumors, but they do have a chance of turning into malignant tumors. Hence, the earliest mode of treatment is surgical resection. The high vascularity of the tumors poses a surgical and anesthetic challenge. Hereby, we present a successfully resected case of large CBT measuring 7 cm × 6 cm. In contrast-computed tomography angiogram of the neck, the hyperdense mass was noted in the left carotid space splaying the left internal carotid artery and external carotid artery. Conventional general anesthesia with controlled ventilation technique was used in the resection of this tumor. The final histopathology report was paraganglioma. She had an uneventful perioperative period and was doing well after 18 months of follow-up.

DOI:10.4103/0972-0820.180202  
Context: Transobturator bypass may be a good alternative or a good solution in hostile groin either scared or infected with severe sepsis in drug addict patients. Aims: Evaluating the results transobturator bypasses in cases where groin cannot be addressed after 2 years follow-up. Settings and Design: This is a personal experience using transobturator bypass as an alternative management in a patient with either groin infection or scared groin in recurrent occluded grafts. Subjects and Methods: Ten cases in which transobturator bypass was performed; late graft occlusion was the indication in (five cases) while groin infection was the indication in the other (five cases). In all patients, common iliac - popliteal bypass was performed. In drug addict patients; infected groin, the tunnel was fashioned in a plane deep to the adductor muscles to be rather away from the infected areas, while in cases of graft occlusion, the much easier subcutaneous plane was chosen to allow easier surveillance of the graft. Results: Obturator bypass was performed in ten cases; five occluded grafts and five infected groin, four of them were addicts. One of the drug addicts presented with groin mass while three of them presented shocked and rupture infected pseudoaneurysm. One died of fulminant sepsis. Two years follow-up, seven grafts were patent. Only three experienced major amputations. Conclusions: The proper timing of the procedure, use of endarterectomy as well as the proper choice of the plane of the tunnel is considered essential prerequisites for a successful outcome.

July-September 2016, 3(3):90-95
DOI:10.4103/0972-0820.186723  
Background: Carotid body tumours (CBTs) are rare but highly vascular neoplasms originating in the paraganglionic cells of the carotid bifurcation. Exact etiology of these tumors is not known. Male and female distributions are equal except at high altitude where females appear to predominate. Diagnosis of a chemodectoma usually begins with a color flow duplex scan. Magnetic resonance angiography are also useful, especially to evaluate bilateral disease. Conventional Arteriography with CT Angiography are valuable, especially in larger tumours, and are regarded as the best tools for diagnosis. The treatment of choice for carotid body tumours is surgical removal. Shamblin's classification system is used to categorize carotid body tumours based on their size and the difficulty of surgical resection. Results: It was observed that majority of the patients in this study were females numbering 35(79.45%) whereas there were 9 (20.43%) males. commonest age group involved was of patients 50 to 59 years of age. Surgery was done in all 44 (100%) patients with complete resection in 41 (93.07%) and incomplete in 3 (6.81%) patients. 10 (23%) were Shamblin grade 1, 29 (66%) grade 2 and 5 (11%) grade 3. ECA repair was done in 4 (9.08%) of patients, ICA repair in 2 (4.54%), ECA ligation in 2 (4.54%) and vascular graft was used in 1 (2.27%) of patients. 7 (15.89%) had transient cranial nerve palsy most commonly involving hypoglossal nerve. 3 (6.81%) had permanent cranial nerve palsy. In 6 (13.62%) patients there was local wound infection .There was post op stroke in 2 (4.54%) of patients. No operative mortality was seen.43 (97.61%) patients were proved to be paraganglionomas on HPE while 1 (2.27%) patients had inconclusive biopsy on Histopathological examination. Conclusion: Although rare, Carotid body tumor is still a pathology that we encounter in our experience and it should be kept in mind as a differential diagnosis for painless lateral neck masses.

Sunil Joshi, Nivedita Mitta
October-Decenber 2014, 1(1):26-28
DOI:10.4103/0972-0820.142365  
Mycotic aneurysms as a result of salmonella arteritis are rare in the era of broad spectrum antibiotics. However, few cases have been reported in cases of immunosuppression, presence of cardiovascular prosthetic materials or intravenous drug addiction. Though Salmonella infections cause aortitis and aortic aneurysms in elderly patients with atherosclerosis, it is rare to have common iliac artery aneurysms in young adults. High index of suspicion and aggressive investigation is required to detect these cases as the clinical presentation may be vague. Management of mycotic aneurysms is challenging, requiring emergency surgery. We hereby present a successful management of salmonella mycotic aneurysm of iliac artery in a young adult with no atherosclerotic risk factors.

Background and Aim: Unfractionated heparin (UFH) or low-molecular-weight heparin is the treatment for established lower limb deep vein thrombosis (DVT). This study was performed to report our experience of treating the same with UFH. Patients and Methods: This was a retrospective analysis of patients with lower limb DVT managed between 1983 and 2014 at Jawaharlal Medical College, Aligarh, India. Results: This analysis included 83 males and 210 females. Mean age of patients was 34.5 ΁ 11.5 years. Most common age group involved in was 20-30 years (33.79%). Most common symptom was limb swelling (90.8%). Most common risk factor was postpartum period. Among postpartum group, primigravida was most commonly involved group. Left limb involvement was found in 195 patients (65.8%). Proximal DVT was present in 215 (73.33%) patients. In proximal patient group, 74.41% presented with more than 90% block while in distal patient group, 66.67% presented with more than 90% block of the venous system. After 3 weeks of treatment, 29.52% and 15.49% were found to have block of proximal and distal deep veins, respectively, which further declined to 1.78% and 3.45% after 6 months of presentation with continued treatment. Six patients died during the course of treatment. Conclusion: Lower limb DVT respond well to UFH, hence should be used for treatment of same with comparable results. DVT can lead to fatal pulmonary embolism and patients should be admitted till target International Normalized Ratio is achieved.

Brendan Hermenigildo Dias, Santosh Antony Olakkengil
January-March 2015, 2(1):7-11
DOI:10.4103/0972-0820.152824  
Aim: The aim was to evaluate the various factors predicting patency following fistulography and percutaneous interventions in the management of nonfunctioning native vascular access. Materials and Methods: Retrospective analysis of 61 patients with native arteriovenous fistulae (AVF) who underwent fistulography and percutaneous interventions from January 2010 to December 2013. Mean patient age was 47 (23-78) years. 69% (42 of 61) of the patients were males. 56% (34 of 61) of patients underwent elbow AVF creation, and the remaining were forearm AVFs. Median time from fistula creation to fistulography was 9 months. On fistulography, hemodynamically significant (>50%) stenosis were identified in 93% (57 of 61) of patients. Angioplasty was attempted in 88% (54 of 57) of fistulae. In 14% (8 of 54) of cases, stent was placed. Results: Technical success was achieved in 98% (53 of 54) of fistulae following angioplasty. Clinical success (ability to use the AVF for successful hemodialysis) was noted in 87% (47 of 54) of cases. About 52% (32 of 61) of the fistulae had multiple stenosis. The most common location of stenosis was the venous limb of the fistula (70%). The primary patency rates were 75.4%, 68.9%, and 30% at 3, 6 and 12 months. The secondary patency rates were 100%, 89%, and 70% at 3, 6 and 12 months. The absence of palpable thrill postprocedure was found to be a risk factor for both primary, as well as secondary patency rates. Conclusions: Our results demonstrate that fistulography and percutaneous interventions in the form of angioplasty and stenting are helpful in maintaining the patency of nonfunctioning native vascular access. We found that the most important predictor of fistula patency following percutaneous interventions is the presence of palpable thrill. Our study also showed that stent placement is effective in treating venous stenotic lesions in native arteriovenous fistula hemodialysis patients after unsatisfactory balloon dilatation.

Aasim Khan, Thodur Vasudevan
January-March 2016, 3(1):15-19
DOI:10.4103/0972-0820.180204  
Introduction: True aneurysms of the innominate artery are rare and continued controversy exists in literature regarding the best management of these aneurysms. Patients and Methods: The present study reviewed a 5-year experience of managing IA true aneurysms between 2010 and 2015. There were two patients aged 63 and 77 years who were treated successfully by a selective open debranching technique for the exclusion of the aneurysms. The mean follow-up was 2 years. Preoperative information was derived from spiral computed tomography (CT) scanning, magnetic resonance imaging, and color Doppler imaging (CDI). Results: One male and one female were treated successfully. The most common indication for intervention was transient ischemic attack (100%). The 30-day surgical mortality was zero. Graft patency at 6 months as confirmed by CDI was 100%. One patient had graft-related complication at 6 months and subsequently at 24 months which was revised successfully. Conclusion: Exclusion bypass is a satisfactory treatment of these proximal aneurysms and durable. The proximity to the aortic arch makes endovascular treatment challenging and would depend on the dimensions of the arch and ascending aorta. De-branching simplifies the treatment pathway. The natural history of these isolated aneurysms is unknown.
