Results: A total of 2465 vessels were targeted with fenestrations and 151 with chimney grafts (CG); intraoperative target vessel preservation was 98.6% and 98.0%, respectively. Cumulative 30-day mortality was 3.4%, 2.4%, and 5.3% for open surgery, F-EVAR and Ch-EVAR, respectively (p=NS). Impaired renal function was noted in 18.5%, 9.8%, and 12% following open surgery, F-EVAR, and Ch-EVAR, respectively (open vs. F-EVAR: p<0.001). New-onset dialysis was required postoperatively in 3.9%, 1.5%, and 2.1%, respectively (open vs. F-EVAR: p<0.001). Postoperative cardiac complications were noted in 11.3%, 3.7%, and 7.4%, respectively (open vs. F-EVAR: p<0.001). The incidence of ischemic stroke was 0.1% and 0.3% following open surgery and F-EVAR, but 3.2% after Ch-EVAR (open vs. Ch-EVAR: p=0.002; F-EVAR vs. Ch-EVAR: p=0.012). Early proximal type I endoleak was lower after F-EVAR compared to Ch-EVAR (4.3% vs. 10%, respectively, p=0.002).

Fig 6 stent vs emobliz

RESULTS: Covered stent placement was successful in 14 of 16 patients (88%); embolization was successful in 10 of 11 (91%) patients. For the embolization group, the overall 30-day and 1-year survival rate was 70%, and the 1- and 2-year survival rate was 56%; for the covered stent group, these rates were 81% and 74%, respectively. The 30-day patency of the covered stent was 84%, and 1-year patency was 42%; clinically relevant ischemia was observed in two patients. Infarction distal to the embolized vessel occurred in 6 of 11 patients (55%).
