Preoperatively detected sarcopenia as reflected by psoas muscle area (PMA) is associated with postoperative mortality after abdominal aortic aneurysm (AAA) repair. We studied, whether changes in PMA and lean PMA (LPMA) after endovascular aortic repair (EVAR) are associated with postoperative survival. ⋯ The most significant loss of skeletal muscle occurs during the first year after EVAR. The relative change in PMA from baseline is an independent predictor of mortality. For every 10% unit increase in ΔPMA/baseline CT muscle parameter bilaterally, there was a 21% decrease in the probability of death during follow-up. Early detection (from CT studies) and prevention of sarcopenia may potentially improve survival in EVAR-treated patients.

To determine the rates and risk factors of complications related to cerebrospinal fluid drainage (CSFD) during first stage and completion fenestrated-branched endovascular aortic repair (F-BEVAR) of pararenal and thoracoabdominal aortic aneurysms. ⋯ Although CSFD is widely used to prevent ischemic spinal cord injury during complex aortic repair, the risk of major CSFD-related complications is not negligible and should be carefully weighed against its potential benefits. One-third of spinal cord injuries were caused by CSF drain placement. The use of fluoroscopic guidance may decrease the risk of CSFD-related complications.

Patients undergoing lower extremity bypass (LEB) for peripheral artery disease require intensive health care resource utilization including rehabilitation and skilled nursing facilities. However, few studies have evaluated factors that lead to nonhome discharge (NHD) in this population of patients. This study sought to predict NHD by preoperative risk factors in patients undergoing LEB for peripheral artery disease using a novel risk score. ⋯ This novel risk score was highly predictive for NHD after LEB for peripheral artery disease using only preoperative comorbidities. High-risk patients account for 12% of LEB but nearly a third of all patients requiring NHD. This risk score can be used preoperatively to determine high-risk patients for NHD, which may help improve preoperative counseling and hospital efficiency by allocating resources appropriately.

Patients who undergo endovascular abdominal aortic aneurysm repair (EVR) remain at risk for reintervention and rupture. We sought to define the 5-year rate of reintervention and rupture after EVR in the Vascular Quality Initiative (VQI). ⋯ More than one in five Medicare patients undergo reintervention within 5 years after EVR in the VQI; late rupture remains low at 3%. Black patients, those with large aneurysms, and those who undergo EVR urgently and emergently have a higher likelihood of adverse outcomes and should be the focus of diligent long-term surveillance.

The objective of this study was to compare short-term outcomes in patients who underwent thoracic endovascular aortic repair (TEVAR) with stent grafts alone or with a composite device design (stent graft plus bare-metal aortic stent) for acute type B aortic dissection in the setting of malperfusion. ⋯ In patients with acute type B aortic dissection in the setting of branch vessel malperfusion, the use of a composite device with proximal stent grafts and distal bare aortic stent appeared to result in lower malperfusion-related mortality than the use of stent grafts alone. The 30-day rates of morbidity and secondary interventions were similar between the groups.
