Comparative Study
Estimating risk of adverse cardiac event after vascular surgery using currently available online calculators.
The decision to proceed with vascular surgical interventions requires evaluation of cardiac risk. Recently, several online risk calculators were created to predict outcomes and to lead to a more informed conversation between surgeons and patients. The objective of this study was to compare and further validate these online calculators with actual adverse cardiac outcomes at a single institution. ⋯ Although online cardiac risk calculators of adverse surgical events are easy to use and to reference in broad surgical decision-making, there is significant variability in their predictability at the procedure and institutional level. Our data suggest that ACEs often occur at a higher rate than expected on the basis of calculated risks profiles, thus creating a platform for future discussion about preoperative evaluation and postoperative care decision-making models.

The optimal initial revascularization strategy remains uncertain for patients with peripheral arterial disease. The purpose of this study was to evaluate current nationwide selection and perioperative outcomes of patients undergoing bypass or endovascular intervention for infrainguinal disease in those with no prior ipsilateral revascularization. ⋯ An endovascular-first approach as a revascularization strategy for infrainguinal disease was associated with substantially lower early morbidity but not mortality, at the cost of higher rates of postoperative secondary revascularizations. As a national representation of first-time revascularizations, this study highlights the early endovascular perioperative benefit, although more robust long-term data are needed to adopt either one strategy or the other in select patients with peripheral arterial disease.

Patients undergoing endovascular aneurysm repair (EVAR) for abdominal aortic aneurysms can exhibit variations in sac behavior ranging from complete regression to expansion. We evaluated the impact of sac behavior at 1-year follow-up on late survival. ⋯ These data suggest that an abdominal aortic aneurysm sac diameter increase of at least 5 mm at 1 year, although infrequent, is independently associated with late mortality regardless of the presence or absence of endoleak and warrants close observation and perhaps early intervention.

Patients with medically managed type B aortic dissection (TBAD) have a high incidence of aorta-related complications over time. Whereas early thoracic endovascular aortic repair (TEVAR) to seal the entry tear can promote aortic remodeling and prevent late aneurysm formation, there are sparse data as to which patients will benefit from such therapy. The goal of this study was to identify clinical and anatomic factors that are associated with the need for subsequent aortic intervention in patients who present with uncomplicated TBAD. These factors could guide the selection of patients who will benefit from TEVAR in the subacute phase. ⋯ Nearly 40% of patients who present with an uncomplicated TBAD will ultimately require an aortic intervention. All of the late interventions were performed for aneurysmal degeneration. A variety of readily available anatomic features can predict the need for eventual operative intervention in TBAD; accordingly, these parameters can guide the desirability of early TEVAR.

Accurate and convenient methods for assessing a patient's risk of postoperative morbidity and mortality comprise important tools in clinical decision-making. Whereas some aspects of the patient's fitness for surgery can be easily quantified, measurement of the patient's frailty is often difficult or time-consuming. Previous research in the context of multiple types of major surgical procedures has reported psoas-L4 vertebral index (PLVI) to be a useful predictor of postoperative morbidity and mortality. ⋯ PLVI did not predict AFS after intervention for peripheral arterial occlusive disease. This is contrary to the ability of PLVI to predict perioperative and midterm survival after abdominal aortic aneurysm repair and other major abdominal surgery.
