Bottom Line: Endovascular repair of aorta in comparison to open surgery has a low early operative mortality rate, but its long-term results are uncertain.All patients were followed up for 13-18 months.The major event-free survival rate was 80.7% for endovascular repair of AAA, 85.7% for endovascular repair of TAA, and 65.6% for endovascular repair of TAD.

ABSTRACT

Background: Endovascular repair of aorta in comparison to open surgery has a low early operative mortality rate, but its long-term results are uncertain.

Objectives: The current study describes for the first time our initial four-year experience of elective endovascular aortic repair (EVAR) at Tehran heart center, the first and a major referral heart center in Iran, as a pioneer of EVAR in Iran.

Patients and methods: A total of 51 patients (46 men) who had the diagnosis of either an abdominal aortic aneurysm (AAA) (n = 36), thoracic aortic aneurysm (TAA) (n = 7), or thoracic aortic dissection (TAD) (n = 8) who had undergone EVAR by Medtronic stent grafts by our team between December 2006 and June 2009 were reviewed.

Results: The rate of in-hospital aneurysm-related deaths in the group with AAA stood at 2.8% (one case), while there was no in-hospital mortality in the other groups. All patients were followed up for 13-18 months. The cumulative death rate in follow-up was nine cases from the total 51 cases (18%), out of which six cases were in the AAA group (four patients due to non-cardiac causes and two patients due to aneurysm-related causes), one case in the TAA group (following a severe hemoptysis), and two cases in the TAD group (following an expansion of dissection from re-entrance). The major event-free survival rate was 80.7% for endovascular repair of AAA, 85.7% for endovascular repair of TAA, and 65.6% for endovascular repair of TAD.

Conclusion: The endovascular stent-graft repair of the abdominal and thoracic aortic aneurysm and aortic dissection had high technical success rates in tandem with low-rate early mortality and morbidity, short hospital stay, and acceptable mid-term free symptom survival among Iranian patients.

Mentions: From the beginning of EVAR in 2006 to 2009, 100% of the patients who were treated by our team had been followed up for an average of thirteen months in the group with endovascular repair of abdominal aortic aneurysm, for an average of 18 months in the group with endovascular repair of thoracic aortic aneurysm, and for an average of 15 months in the group with endovascular repair of aortic dissection. Totally, nine patients died during this follow-up. The cumulative rate of death was 16.7% (six cases) in the abdominal aortic aneurysm group (four patients by non-cardiac causes and only two patients by aneurysm-related causes), 14.3% (one case) in the thoracic aortic aneurysm group (following severe hemoptysis), and 25.0% (two cases) in the aortic dissection group (one following an expansion of the dissection from re-entrance and the second one, with the clinical feature of chest pain and unknown exact reason). The severe event-free survival rates were 80.7% for endovascular repair of abdominal aortic aneurysm, 85.7% for endovascular repair of thoracic aortic aneurysm, and 65.6% for endovascular repair of aortic dissection (Figure 2).
