Peripheral infected aneurysms: report of 15 cases

ABSTRACT

In this retrospective study we report 15 cases of peripheral infected aneurysms. The sex ratio was 13/2 and the mean age was 23 years. Patients presented with infection mean age was 32 years. Patients presented with infection syndrome in 9 cases, vascular mass in 11 cases and limb ischemiae in 2 instances. Arterial lesion was documented and confirmed by echography, tomodensitametry and angiography. The infection was recognized by different criteria the main one being micro-organism isolation. In 10 cases aneurysm was secondary to bacterial endocarditis, in 4 it was primary and in one case it was related to arterial catheter procedure. Treatment is based on antibiotics and surgical management by removing of infected aneurysm and arterial restauration whenever possible. Arterial floweriest restablishment was done in 10 patients among whom 6 by anatomic procedures 4 by extra-anatomic ones. Hospital morality rate was 13 percent [2/15], all deaths occurred after cardiac surgery for endocarditis. Two patients were readmitted for adjacent spine infection, one month and one and a half respectively after surgery. One young patient required late surgery [aorto-bifemoral bypass] 24 months after initial treatment and one patient died by intro-duodenal rupture of recurrent review allow discussion of clinical, physiopathological and specially therapeutic aspects of infected aneurysm
