We assessed the incidence and outcomes of graft-related secondary interventions (ie, open conversion or proximal or distal extensions) after elective thoracic endovascular aortic repair (TEVAR) for aneurysmal disease. ⋯ Intermediate and long-term results of elective TEVAR for DTAA demonstrate good durability, with acceptable rates of graft-related secondary interventions. Age, fusiform aneurysm morphology, and extent of proximal landing zones <3 cm were significant factors that led to subsequent secondary interventions.

Gender differences in abdominal aortic aneurysm presentation, repair, and mortality in the Vascular Study Group of New England.
Prior studies of gender differences in abdominal aortic aneurysm (AAA) repair suggest there may be differences in presentation, suitability for endovascular aneurysm repair (EVAR), and outcomes between men and women. ⋯ Women with AAAs are being treated at older ages and smaller AAA diameters and are undergoing rupture repair at smaller diameters than men. Women are more likely to experience perioperative complications as a result of less favorable vascular anatomy. Age >80 years, comorbidity, presentation, and type of repair are more important predictors of mortality than gender.

The Comprehensive Risk Assessment for Bypass (CRAB) facilitates efficient perioperative risk assessment for patients with critical limb ischemia.
Specific perioperative risk assessment models have been developed for bariatric, pancreatic, and colorectal surgery. A similar instrument, specific for patients with critical limb ischemia (CLI), could improve patient-centered clinical decision making. We describe a novel tool to predict 30-day major morbidity and mortality (M&M) after bypass surgery for CLI. ⋯ The CRAB is a CLI-specific, risk assessment instrument derived from multi-institutional American College of Surgeons-National Surgical Quality Improvement Program surgical outcomes data that out-performs existing prognostic risk indices in the prediction of clinically significant adverse events after bypass surgery. Use of the CRAB as a risk assessment tool provides an evidence basis for patient-centered clinical decision making and may have a role in identifying patients at higher risk for surgical revascularization in whom an endovascular approach is preferable.

Vascular surgical training currently has to cope with various challenges, including restrictions on work hours, significant reduction of open surgical training cases in many countries, an increasing diversity of open and endovascular procedures, and distinct expectations by trainees. Even more important, patients and the public no longer accept a "learning by doing" training philosophy that leaves the learning curve on the patient's side. The Vascular International (VI) Foundation and School aims to overcome these obstacles by training conventional vascular and endovascular techniques before they are applied on patients. ⋯ Several evaluations of these courses show that tutor-assisted training on lifelike models in an educational-centered and motivated environment is associated with a significant increase of general and specific vascular surgical technical competence within a short period of time. Future studies should evaluate whether these benefits positively influence the future learning curve of vascular surgical trainees and clarify to what extent sophisticated models are useful to assess the level of technical skills of vascular surgical residents at national or international board examinations. This article gives an overview of our experiences of >20 years of practical training of beginners and advanced vascular surgeons using lifelike pulsatile vascular surgical training models.

Race as a predictor of morbidity, mortality, and neurologic events after carotid endarterectomy.
Racial disparities in the outcomes of patients undergoing carotid endarterectomy (CEA) have been reported. We sought to examine the contemporary relationship between race and outcomes and to report postdischarge events after CEA. ⋯ Black race is an independent risk factor for 30-day mortality after CEA. A significant proportion of strokes and deaths occur after discharge in both racial groups evaluated.
