Aortic arch disease is a challenging clinical problem, especially in high-risk patients, in whom open repair can have morbidity and mortality rates of 30% to 40% and 2% to 20%, respectively. Aortic arch chimney (AAC) stents used during thoracic endovascular aortic repair (TEVAR) are a less invasive treatment strategy than open repair, but the current literature is inconclusive about the role of this technology. The focus of this analysis is on our experience with TEVAR and AAC stents. ⋯ TEVAR with AAC can be performed with high technical success and acceptable morbidity and mortality in high-risk patients. Unplanned AAC placement during TEVAR results in an elevated stroke risk, which may be related to the branch vessel coverage necessitating AAC placement. Acceptable midterm survival can be anticipated, but aorta-related reintervention is not uncommon, and diligent follow-up is needed.

Comparative Study Observational Study
Outcomes of endovascular and open surgical repair of ruptured abdominal aortic aneurysms in elderly patients.
Endovascular aneurysm repair (EVAR) is becoming the preferred treatment modality for patients with a ruptured abdominal aortic aneurysm (rAAA). Although the survival advantage of EVAR over open aortic repair (OAR) has been shown in some studies, it is unclear whether this benefit extends to elderly patients. We sought to evaluate the outcomes of rAAA repair in octogenarians. ⋯ Elderly patients have significant but acceptable perioperative mortality and morbidity after rAAA repair. Use of endovascular repair in the elderly population has increased and is associated with better perioperative survival and 30-day outcomes compared with traditional open repair in this study.

The effect of preoperative malnutrition on outcomes in patients undergoing major vascular surgery is unclear. We investigated the effects of preoperative hypoalbuminemia, a marker for malnutrition, on outcomes after open abdominal aortic aneurysm repair (OAR) and endovascular abdominal aortic aneurysm repair (EVAR). ⋯ Preoperative hypoalbuminemia is associated with increased postoperative morbidity and mortality in a severity-dependent manner among patients undergoing OAR or EVAR. Evaluation and optimization of nutritional status should be performed preoperatively in this high-risk population.

Comparative Study
Reimbursement in hospital-based vascular surgery: Physician and practice perspective.
The purpose of this study was to determine change in value of a vascular surgery division to the health care system during 6 years at a hospital-based academic practice and to compare physician vs hospital revenue earned during this period. ⋯ At medical centers where vascular surgeons are hospital based, vascular care reimbursement decreased substantially from 2010 to 2015 when case complexity and inflation were considered. Physician reimbursement (professional fees) decreased at a significantly greater rate than hospital reimbursement for vascular care. This trend has significant implications for salaried vascular surgeons in hospital-based settings, where the majority of revenue generated by vascular surgery care is the technical component received by the facility. Appropriate care for patients with vascular disease is increasingly resource intensive, and as a corollary, reimbursement levels must reflect this situation if high-quality care is to be maintained.

Timing of extubation after open aortic procedures varies across hospitals. This study was designed to examine extubation timing and determine its effect on length of stay (LOS) and respiratory complications after elective open aortic surgery. ⋯ Extubation in the operating room is associated with shorter LOS and morbidity after open aortic surgery. EBL, procedure time, and center variation account for variability in extubation timing. These data advocate for standardized perioperative respiratory care to reduce variation, improve outcomes, and reduce LOS.
