Abstract
This study was conducted in Alexandria Main University Hospital in the period between 1/10/2016 and 1/10/2017 on 20 patients (90% males) with mean age of 36.05 years who presented with infected femoral pseudoaneurysms resulting from intravenous drug abuse. We performed ligation and debridement of the pseudoaneurysms and observed the limbs post-operatively to determine their outcome after ligation. We performed extra-anatomical PTFE bypasses for patients who were critically ischemic and required revascularization. We observed the different factors that might affect this outcome such as presentation of the swelling, level of arterial ligation and Ankle Brachial Index measurements pre and post-operatively.
All patients were HCV positive, and 10% were HIV positive. Only one patient had history of IHD and COPD. 90% of our patients had no past surgical history.
Eight of our patients (40%) presented by an impending rupture pseudoaneurysm, and the rest had ruptured swellings.
In 16 patients (80%) we performed triple vessel ligation of the common femoral artery, superficial femoral artery and profunda femoris artery, and in these cases 13 (81.3%) had compensated limbs with a minimum post-operative ABI of 0.21. In the remaining three patients the limbs were decompensated and required revascularization. The post-operative ABI in two of these patients was 0, and in one was 0.24.
In the other four patients we performed ligation of the external iliac artery, in all these cases the limbs were decompensated and post-operative ABI was 0.
Of all our patients, 13 were compensated (65%), two patients (10%) required major amputation (hip disarticulation), four required extra-anatomical bypass (20%), and one patient had toe and heel gangrene (5%).
We found the level of arterial ligation and the post-operative ABI measurements to be significant predictors of limb outcome, while the DROP between pre and post-operative measurements was found to be non-significant.
