Abstract
Objective To evaluate the perioperative and long-term effects of endovascular aneurysm repair(EVAR) of infrarenal abdominal aortic aneurysm (AAA).Methods Clinical data of 131 AAA cases undergoing EVAR were retrospectively evaluated for the safety and long-term efficacy.Results The operative time was (137 ±29) min,blood loss was (142 ±20) ml,blood transfusion was (46 ± 26) ml,ICU staying time was (17 ± 4) h.Major perioperative complications were severe heart failure in 8 cases,myocardial infarction in 2 cases,pulmonary complications in 5 cases,internal leakage in 4 cases.During the period of up to 60 months there were15 cases of endoleak including 8 cases of type Ⅰ,5 cases of type Ⅱ,1 each case of type Ⅲ and Ⅳ and 2 deaths.By Kaplan-Meier survival analysis there were complications developing after 60 months and up to 40％ of them needing reintervention.Conclusions Endovascular repair is the safe treatment for AAA,but discharged patients need close long-term follow-up.Complications that ensued need intensive management.
