Short and intermediate outcome of endovascular aortic aneurysmal repair, a multicenteric study

Abstract

BACKGROUND: The availability of aortic stent-grafts has permitted an obvious change in the management of abdominal aortic aneurysms (AAA). For elective cases open surgical repair has been widely superseded by the use of stent-graft. With the rapid evolution of the endovascular technology, a significant development in stent-graft techniques was achieved in conjunction with a better understanding of how to utilize stent-grafts. METHODS: A multicenter prospective study in which 49 patients were enrolled, they underwent an elective endovascular aneurysm repair (EVAR) procedure for infrarenal AAA in two different institutions, Kasr Al-ainy School of Medicine, Cairo University and King’s College Hospital in London, the selected patients were followed up for 6 months after the procedure. Data relating to demographics and pre-operative comorbidities were recorded. Aneurysm morphology was reviewed by computed tomography angiography scans. Clinical data was collected through operative records and afterward through outpatient clinic follow-up sessions. RESULTS: Overall survival was 94% over a period of 6 months calculated using KaplanMeier Survival Curve. CONCLUSIONS: Endovascular repair resulted in fewer perioperative deaths. This study provides insight into clinical parameters that can be used to stratify patients’ post-EVAR surveillance and need for re-intervention and it came to the conclusion that EVAR could be considered as the standard repair for uncomplicated infrarenal AAA.
