15Mathias 2009 (Ακτινολόγος) In our series, closure was successfully accomplished in 304 of 308 patients (98%). Additional manual compression was necessary in 18 (7%) for more than 10 minutes. Four patients needed surgical closure of the puncture hole. Follow-up examinations with ultrasound showed six pseudoaneurysms. Five of them weretreated with ultrasound-guided compression. In one patient, compression failed to build a thrombus with occlusion of the false aneurysm. The patient was referred to vascular surgery, but a control examinationon the planned day of surgery revealed a spontaneous occlusion of the false aneurysm. Surgical correction was no longer necessary.With such a high success rate of arterial closure afterEVAR, we routinely do not need any surgical backup.EVAR has become a percutaneous procedure for the majority of our patients. Future developments with downsizing of the endograft catheters to 16 F will make it even safer to perform EVAR percutaneously.

In the LA group,two patients had to be converted to GA, one because of a dissection and one because of anxiety. In 13% of thepatients in the LA group, additional intravenous sedation or analgesia was required. Operating time and length ofstay in intensive care was shorter in the LA and RA groups than in the GA group (P < .001). Length of stay inhospital and time to ambulation and regular diet was shorter in the LA group compared with the RA and GA groups (P < .001).
