Mid-Term Results of Endovascular Repair in Isolated Iliac Artery Aneurysms: A Single-Center Experience

Objective: The aim of this prospective study was to present the mid-term results of endovascular aortic repair of isolated iliac artery aneurysms performed in our clinic. Material and Methods: Endovascular aortic stent grafting was performed in a total of 33 patients between July 2010 and March 2014. Of the patients, 32 (97%) were males and 1 (3%) was a female, their ages ranging between 54 and 83 years (mean age 69.97 ± 8.27 years). The Gore Excluder® stentgraft was used in all patients. All patients were followed-up with computed tomography (CT). Results: The mean diameter of the aneurysms in the patients was 42.93 ± 8.05 mm. Aortabiiliac grafts were successfully implanted in all of the patients (100%). The intervention was performed under general anesthesia in 20 (60.6%) and spinal anesthesia in 13 (39.3%) patients. There was no mortality during the intervention. Furthermore, internal iliac artery embolization was performed in 9 patients. None of the patients required blood transfusion. Following the intervention, all patients were directly sent to the ward, and discharged from the hospital on the postoperative day 1. During an average of 24-month CT scan follow-up, type 1 endoleak was determined in 4 patients. An additional endovascular intervention was performed in 3 patients during the follow-up period. Conclusion: In addition to significant decrease in mortality and morbidity, endovascular repair markedly decreases the need for blood transfusion and intensive care, and shortens the length of hospital stay. We suppose that endovascular repair will replace surgery as the experience of surgeons increase, and graft technologies advance.
