The aim of this study is overview of endovascular University Hospital Centre Split. The sAAA refers to a number sAAA (symptomatic abdominal aortic aneurysm) treatment in the of symptoms associated with aneurysm. EVAR (endovascular aortic repair) is increasingly used as an alternative to an open method that cmTies a number of advantages. Between January 2016 and February 2017, eight patients were admitted to the University Hospital Centre Split due to sAAA, following clinical and diagnostic treatment by a team of vascular surgeons and emergency radiologists, and ultimately treated with EVAR. Two patients had femoral endarterectomy. One patient had fistula of the right external iliac artery with left common iliac vein. After EVAR with embolization of the right internal iliac artery, the fistula was resolved. Also, one patient had occluded left external iliac artery and femoral-femoral bypass graft was made. After the procedure, two patients had endoleak of type II. Perioperative mortality was zero. On control examinations, all patients were with good general condition and without complications. A prompt diagnosis of sAAA and good team working will result of emergency endovascular procedure and resolve the risk for abdominal aortic aneurysm rupture. 展开更多
