Management of Post-traumatic Peripheral Arterial Pseudoaneurysm in Antananarivo

Background: Pseudoaneurysm is the usual complication of arterial injury. The aim of this study is to describe the etiology and the management of post-traumatic peripheral arterial pseudoaneurysm in Antananarivo. Methods: This is a bicentric retrospective study for 10 years period (January 2010 to December 2019), performed in Cardiovascular Unit in Joseph Ravoahangy Andrianavalona Teaching Hospital and in Vascular Unit in Soavinandriana Hospital Center, including all patient who underwent a surgical procedure of post-traumatic peripheral arterial pseudoaneurysm. Results: 38 patients were recorded in 10 years period, which 26 patients recorded in JRA hospital and 12 patients in Soavinandriana Hospital. Patients were 33 males (86.84%) and 5 females (13.15%). Gunshots wounds (47.36%) and stabs wounds (34.21%) were the commonest circumstances of etiology. Pulsatile mass (84.21%), pain (60.52%) and palpable thrill (71.05%) were the usual of peripheral pseudoaneurysm. Doppler ultrasound (94.73%) and computed tomographic angiography (13.15%) performed the diagnosis of the pseudoaneurysm. Femoral artery (39.47%) and brachial artery (31.57%) were the most involved vessels. All patients underwent an open surgery. Surgical procedures were arterial repair in 26 patients (68.42%), reversed saphenous vein interposition in 5 patients (13.15%), PTFE graft in 2 patients (5.26%) and ligation excision in 5 patients (13.15%). There was no reoperation or mortality in early postoperative period. Conclusion: Trauma is the most common etiology of pseudoaneurysm in Antananarivo. Open surgical repair remains the procedure to treat the post-traumatic peripheral arterial pseudoaneurysm in our experience.
