Management of Infected Femoral Pseudoaneurysms in Intravenous Drug Abusers: A Review of 57 Cases

Abstract

The present study was carried out to evaluate the clinical characteristics and surgical methods used for the management of infected femoral pseudoaneurysms secondary to illegal drug injections. Fifty seven consecutive patients who presented with infected pseudoaneurysm of the lower limb and were admitted to the emergency department of Sina Hospital during a 5-year period were enrolled in this study. Surgical methods performed consisted of vein angioplasty, simple ligation of femoral artery, and emergent or delayed revascularization. All participating patients were males with a mean age of 36.7 years. Three (5.3%) and two (3.5%) patients underwent primary repair and emergent vascular bypass, respectively; whereas delayed revascularization was performed in only eight (14%) cases. Forty four (77.2%) patients achieved a normal lifestyle without any vascular bypass. Early critical ischemia and late claudication was reported in two (3.5%) and eight (14%) patients, respectively. Other complications such as amputation and mortality were rarely reported. In our study, simple ligation of the external iliac or femoral artery was the most frequent management method for treating infected femoral pseudoaneurysms. Simple ligation of the external iliac or femoral artery seems to be a safe procedure in drug abusers presenting with infected femoral pseudoaneurysms.
