title: [Anastomotic pseudoaneurysms].
abstract: Anastomotic pseudoaneurysm is a form of false aneurysm, whose wall does not consist of all normal layers of arterial wall. Given the rising number of reconstructive vascular procedures, the increase of anastomotic pseudoaneurysm cases is expected. Therefore, identification of causes, clinical manifestations as well as factors which affect the outcome of operative treatment of anastomotic pseudoaneurysms is of great practical value. This retrospectively-prospective study included 87 surgically treated cases of anastomotic pseudoaneurysms in the period from 1991 to 2002. The most often localization of anastomotic pseudoaneurysms was the inguinal region (68-86.2%). In the majority of cases, they were caused by arterial degeneration in the anastomotic region--56 cases (65.9%) and infection--21 cases (24.7%). The most frequent manifestations of anastomotic pseudoaneurysms were bleeding due to rupture in 26 cases (29.9%) and chronic limb ischaemia in 22 cases (25.3%). An acute limb ischaemia was present in 17 cases (19.5%), the symptoms caused by local compression to the surrounding structures--in 9 cases (10.3%), and in 12 cases (13.8%), the only manifestation of anastomotic pseudoaneurysm was asymptomatic pulsatile mass. In 32 cases (36.8%), surgical treatment involved the resection of anastomotic pseudoaneurysm and graft interposition, whereas in 39 cases (44.8%), bypass procedure had to be performed after the resection. Comorbidity significantly increased mortality in the first 30 days. The use of Dacron graft in primary operation significantly improved early results of operative treatment. Absence of infection as the cause of anastomotic pseudoaneurysm is a statistically important prognostic factor of operative treatment, considering the graft patency, limb salvage, infection, need for reintervention and mortality.
