摘要

Insufficient endografting of infrarenal aortic aneurysms can lead to conversion. Indications for conversion can be the incidence of endoleakage, occlusion of the endograft or progressive aneurysm growth. Over a period of 9.5 years, 235 patients underwent endovascular treatment of infrarenal aortic aneurysms at our clinic. Altogether, 19 conversion procedures were necessary, five of which were primary immediate conversions, while 14 were performed at a later time (> 30 days). This corresponds to a conversion rate of 8.1. Patients treated with primary conversion demonstrated a high mortality rate of 20.0, whereas the elective secondary conversions showed a lethal outcome in 7.7 of cases. At rupture, the mortality rate is significantly higher. Conversion procedures demand a high standard of technical skill and, therefore, should be performed under elective conditions. Careful follow-up after endovascular aortic aneurysm repair is required. The risk of conversion has to be kept in mind when planning endovascular procedures. Specific selection of patients and technical improvement of the endografts reduce the risk.
