Posthospital syndrome (PHS) is an acquired, transient period of health vulnerability after a hospital admission for acute illness. It is characterized by physiologic deconditioning secondary to stressors from disruption in circadian rhythm, depletion of nutritional and physiologic reserve as well as the pain and discomfort associated with hospitalization. PHS is reported as an independent risk factor for readmission and adverse postoperative outcomes. The aim of this study is to investigate whether preoperative hospitalization affects outcomes of elective endovascular repair of abdominal aortic aneurysm (EVAR). ⋯ PHS is an independent risk-adjusted predictor for increased LOS, 30-day readmission, and overall complications after elective EVAR. Recent hospital admission should be assessed carefully before elective EVAR. Medical optimization with an attempt to delay elective surgery by up to 30 days may help to improve surgical outcomes and decrease unnecessary health care expenditures.

The association of higher hospital volume with lower mortality after open abdominal aortic aneurysm (OAAA) repair is well known; however, the underlying mechanism for improved outcomes is poorly understood. Better patient selection, lower risk of complications, and improved ability to rescue patients after adverse events are assumed mechanisms, but few data exist to validate this hypothesis. The purpose of this analysis was to determine the association of hospital volume with patient selection, incidence of complications, and failure to rescue (FTR) after adverse events resulting from OAAA repair. ⋯ Although high-volume institutions performing OAAA repair do not necessarily operate on patients with more comorbidities, there are important differences in the patients selected compared with lower volume hospitals. The risk for development of multiple specific postoperative complications as well as for preventable adverse events preceding FTR is significantly lower in high-volume centers. These findings provide benchmarks for multiple selected quality indicators and further support national initiatives to incentivize regionalization of OAAA care.

Recent data have shown that transcarotid artery revascularization (TCAR) with flow reversal provides a superior method of embolic protection compared with transfemoral carotid artery stenting (tfCAS) with distal embolic protection. Flow reversal or flow arrest systems with proximal endovascular balloon occlusion can also be used through the transfemoral approach; however, their outcomes compared with TCAR with flow reversal and tfCAS with distal embolic protection are poorly described. ⋯ Compared with tfCAS with distal embolic protection, tfCAS with proximal balloon occlusion has similar major outcomes. However, tfCAS with proximal balloon occlusion does not offer the same degree of embolic protection compared with TCAR with flow reversal, given the significantly higher risk of perioperative stroke or death.

Lumbar drain placement with cerebrospinal fluid (CSF) drainage is an effective adjunct for reducing the risk of spinal cord ischemia in patients undergoing complex aortic aneurysm repair. However, lumbar drain placement is a challenging procedure with potential for significant complications. We sought to characterize complications of lumbar drain placement in a large, single-center experience of patients who underwent fenestrated or branched endovascular aneurysm repair (F/BEVAR). ⋯ Lumbar drain placement for CSF drainage is a commonly employed adjunct to prevent spinal cord ischemia in F/BEVAR. Our experience demonstrates that lumbar drain placement can be performed successfully but is associated with a significant rate of nonfunctionality and a diverse range of complications that, fortunately, do not commonly have significant long-term sequelae.

Previous studies have identified significant gender discrepancies in grant funding, leadership positions, and publication impact in surgical subspecialties. We investigated whether these discrepancies were also present in academic vascular surgery. ⋯ Although there is certainly improved representation of women in vascular surgery compared with several decades ago, a discrepancy still persists. Women tend to have more grants than men and receive less in industry payments, but they hold fewer leadership positions, do not publish as frequently, and are cited less than their male counterparts. Further investigation should be aimed at identifying the causes of gender disparity and systemic barriers to gender equity in academic vascular surgery.
