Anterior tibial artery (ATA) pseudoaneurysm is a rare condition that occurs following lower extremity orthopedic intervention or after trauma. We report a series of cases of pseudoaneurysm which were treated surgically. The diagnosis was confirmed with computed tomography angiogram. Aneurysmal sac excision with ligation of ATA was performed.

| Introduction|| |
Pseudoaneurysms of anterior tibial artery (ATA) are associated with penetrating trauma, high-injury blunt trauma,,, bone fractures, sports activities,, and less frequently after orthopedic interventions. Here, we report a series of cases of ATA pseudoaneurysm that developed posttrauma and spontaneously. History, clinical presentation, treatment, and review of the literature are presented.
| Case Reports|| |
The details of the presentation, diagnosis, and treatment of ATA pseudoaneurysms in five male patients are presented in [Table 1]. All the patients presented to our outpatient clinics except one patient who presented to our emergency department with bleeding 7 days after insertion of Steinmann pin. Two elderly patients denied the history of trauma presented to us with swelling associated with ulcer and cellulitis of leg [Figure 2]. All the patients were examined clinically. There was no history of fever. There were no findings suggestive of connective tissue disorders. Their blood investigations were within normal limits. On physical examination, there was a pulsatile swelling with an area of skin ulceration at the lateral aspect of upper one-third of the leg. Both posterior tibial artery and dorsalis pedis artery pulses were palpable with good triphasic signals, and the plantar arch was patent in all the patients. Ultrasound Doppler studies [Figure 3] were performed, which demonstrated the presence of an ATA pseudoaneurysm, confirmed by Angiogram [Figure 4].
Under regional anesthesia, with tourniquet at the thigh, through an incision over the swelling, the pseudoaneurysm was opened, and the clots were removed. All the patients had opening at the proximal ATA ranging from 5 mm to 1 cm [Figure 5]. Since the posterior tibial artery and the peroneal artery was normal with patent plantar arch, the ATA was ligated [Figure 6] in all the cases.
The postoperative period was uneventful. All the patients had normal posterior tibial artery pulse with the good triphasic flow in the dorsalis pedis artery. The culture of the pseudoaneurysm sac wall was negative in all the patients except in one elderly patient with cellulitis, positive for acinetobacter and he was treated with appropriate antibiotics.
| Discussion|| |
False peripheral artery aneurysms have an incidence of <1%, most are located in the popliteal artery. These aneurysms are caused by trauma or after surgical procedures, either orthopedic or vascular leading to the formation of a pseudoaneurysm. The time from injury to the detection of the pseudoaneurysms has been reported to vary from hours to years, depending on the site, size, and clinical signs and symptoms. The latter may include pain, swelling, a pulsatile mass, distal emboli, neurological deficit, and bleeding. The differential diagnosis includes abscesses, hematoma, and neoplasms., Therefore, high index of suspicion is justified in dealing with such swellings in the vicinity of a major vessel.
To treat pseudoaneurysms of the ATA, the surgical approach has been preferred even recently, to prevent complications of rupture or rapid expansion with resultant pressure on the adjacent nerves. Several methods of repair have been described in the literature for the treatment of a pseudoaneurysm. These include excision of the aneurysmal sac and repair of the lateral wall, end to end anastomosis, graft placement, and ligation of the artery.,,,,,
Before planning the procedure additional research (duplex ultrasonography, computed tomography, and magnetic resonance imaging) should have been undertaken to plan the procedure, whereby collateral flow through the posterior tibial and dorsalis pedis needs to be sufficient.
Other less invasive options for the treatment of anterior tibial pseudoaneurysm included transfemoral embolization with coils, Ultrasound-guided compression, closure with transluminal temporary occlusion of the pseudoaneurysm neck or balloon embolization, covered stent, and direct thrombin injection.,
In our case series, hence the openings of the pseudoaneurysms were wide, and the artery was friable, we ligated the ATA.
| Conclusion|| |
ATA pseudoaneurysms are rare. It can be managed by ligation, provided the posterior tibial artery is patent and maintains vascularity to the anterior compartment and distal limb.
