Management of Pseudoaneurysms in IV Drug Users

Abstract

Introduction: Pseudoaneurysms are major vascular complications in intravenous drug abusers. They are potentially fatal, often infected and require urgent management.

Method: This is a retrospective study of the prevalent practice of their management in our center. The inpatient medical charts of the patients spanning 5 years (Sep 2006 to Aug 2011) were reviewed. Data were obtained on their demographic, clinical, management and outcome parameters.

Result: Among the thirty intravenous drug users presenting with pseudoaneurysms (excluding one who bled to death before surgery), 28 had their femoral artery involved. Most of them (90%) were infected. Nearly half of the patients (45%) were seropositive for HIV and/or HCV. All were operated, with no mortality. Ligation and debridement was the technique used almost exclusively (83%). One brachial artery wasrepaired primarily, whereas 3 femoral and 1 brachial pseudoaneurysms were managed with autologous saphenous vein bypass. Five patients had neurological complications, and 5 others had non-limb threatening claudication which got better with medical management. Mean follow up period was 11 months.

Conclusion: Ligation and debridement appears to be a simple, safe and effective procedure in infected pseudoaneurysms in IV drug users.
