To explore the incidence, predictors, and outcomes of hemodynamic instability (HI) following carotid angioplasty and stenting (CAS). ⋯ HI represents a common occurrence following CAS. While the presence of periprocedural HI alone did not portend a worse clinical outcome, CS-HI was associated with increased risk of stroke. Expeditious intervention to prevent and manage CS-HI is of critical importance in order to minimize adverse clinical events following CAS.

Renal function may be associated with poor outcome following endovascular abdominal aortic aneurysm repair (EVAR), but this relationship has not been adequately investigated. The aim of this study is to evaluate the association of estimated glomerular filtration rate (eGFR) with cardiovascular events and all-cause mortality after EVAR. ⋯ Impaired renal function is associated with an increase in cardiovascular events and mortality following elective EVAR.

Review Meta Analysis
Endovascular repair for ruptured abdominal aortic aneurysm confers an early survival benefit over open repair.
Despite the intuitive advantages of endovascular repair (EVAR) of ruptured abdominal aortic aneurysms (AAAs), uncertainty remains about the optimal management in the absence of convincing high-quality evidence. Our objective was to undertake a comprehensive literature review and perform a meta-analysis of outcome data of treatment modalities for ruptured AAAs. ⋯ Our analysis provides evidence to motivate the adoption of an EVAR-first policy in a nonelective setting and the establishment of standardized protocols for the management ruptured AAAs.

Multicenter Study
Outcomes of lower extremity bypass performed for acute limb ischemia.
Acute limb ischemia remains one of the most challenging emergencies in vascular surgery. Historically, outcomes following interventions for acute limb ischemia have been associated with high rates of morbidity and mortality. The purpose of this study was to determine contemporary outcomes following lower extremity bypass performed for acute limb ischemia. ⋯ Patients who present with acute limb ischemia represent a less medically optimized subgroup within the population of patients undergoing lower extremity bypass. These patients may be expected to have more complex operations followed by increased rates of perioperative adverse events. Additionally, despite equivalent graft patency rates, patients undergoing lower extremity bypass for acute ischemia have significantly higher rates of major amputation and mortality at 1 year.

Open surgical repair of thoracoabdominal aortic aneurysms (TAAAs) is uncommon. Mortality rates of 20% are reported in studies using national data and are 5% to 8% in single-institution studies. Clinical trials are currently evaluating branched and fenestrated endografts. The purpose of this study is to establish a benchmark for future comparisons with endovascular trials using open repair of TAAAs in the National Surgical Quality Improvement Program (NSQIP) database. ⋯ In this study of NSQIP hospitals, the first to analyze open surgical repair of TAAAs, the 30-day mortality rate of 10.0% is similar to single-institution reports. However, morbidity and mortality after open TAAA repair remain high, confirming the need for less invasive procedures.
