Previous studies have reported that endovascular repair (EVAR) of ruptured abdominal aortic aneurysms (RAAAs) has lower postoperative mortality than open repair (OR). However, comparisons involved heterogeneous populations that lacked adjustment for preoperative risk. We hypothesize that for RAAA patients stratified by a validated measure of preoperative mortality risk, EVAR has a lower in-hospital mortality and morbidity than does OR. ⋯ This novel risk-stratified comparison using a national clinical database showed that EVAR of RAAA has a lower mortality and morbidity compared with OR in low-risk and medium-risk patients and that EVAR should be used to treat these patients when anatomically feasible. For RAAA patients at the highest preoperative risk, there is no benefit to using EVAR compared with OR.

Comparative Study
Cost-effectiveness of endovascular repair, open repair, and conservative management of splenic artery aneurysms.
Open repair (OPEN) and conservative management (CONS) have been the treatments of choice for splenic artery aneurysms (SAAs) for many years. Endovascular repair (EV) has been increasingly used with good short-term results. In this study, we evaluated the cost-effectiveness of OPEN, EV, and CONS for the treatment of SAAs. ⋯ EV is the most cost-effective treatment for most patient groups with SAAs, independent of the sex and risk profile of the patient. EV is superior to OPEN, being both cost-saving and more effective in all age groups. Elderly patients should be considered for CONS, based on the high costs in relation to the very small gain in health when treated with EV. The very elderly should be treated with CONS.

The introduction of fenestrated and multibranched endografting transformed the treatment paradigm of patients with thoracoabdominal aortic aneurysms (TAAAs). However, despite the minimally invasive character of the procedure, spinal cord ischemia (SCI) remains a devastating complication. The aim of this study was to address the SCI rates after endovascular TAAA repair and to analyze potential risk factors leading to this complication. ⋯ The SCI rate after endovascular repair of TAAA was 16%, with 8% of those patients suffering from paraplegia. Prophylactic use of CSFD could not reduce the SCI rate and was associated with 6% adverse events. The percentage of thoracic aortic coverage was the most powerful determinant of SCI in these series.
