Short-Term Outcome of Endovascular Repair of AorticAneurysms with Stent Grafts: Initial Results of the FirstConsecutive Series of Endovascular Aortic Repair in Iran

Endovascular aortic repair (EVAR), as a new and less invasive method for treatment ofaortic aneurysms, has shown lower short term complications than routine open surgical repairs. Inthis report we present our results with the first consecutive series of this technique in our patients.
From Dec. 2006, we began a prospective case series of EVAR patients for the first time inIran, and so far, 15 consecutive patients (1 female, 14 male) with the mean age of 66 years (range36 to 89 years old) underwent endovascular aortic aneurysm repair (3 thoracic, 11 abdominal, 1combined thoracic and abdominal) with Medtronic “Talent” or “Valiant” stent grafts. In-hospitaland one month follow up results are reported as short-term outcome.
Results:All 12 abdominal aorta aneurysms (AAA) were infrarenal with an acceptable proximal neck. Ineight patients, associated iliac aneurysms were seen. For 11 AAA patients, routine modular stentgrafts were used and in one case, unilateral stent graft was implanted because of difficulty ofcontrolateral stent graft implantation. Four thoracic aorta aneurysms (TAA) were repaired withValiant stent grafts. One of them was a Marfan patient with recent Bentall surgery and two werepost-surgery saccular aneurysms. In all 15 cases, stent graft implantation was done successfully. Infive cases, mild type II endoleak was seen at the end of the procedure, which was no longerpresent on one month follow up. One patient had post- procedure cerebral stroke with delayed
mortality. No other major complications were seen in 1 month follow up in the other 14 cases.Minor complications like vascular access hematoma, anemia and increased creatinine were
controlled on hospital stay period in some cases. Control CT angiography in some patients
revealed no endoleak or aneurysm enlargement and 6 and 12-month follow up assessment will bedone for mid-term results.
Endovascular repair of aortic aneurysm is feasible and safe for suitable cases based on bothclinical and radiologic findings. Good case selection, good device selection and suitable follow up
