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.

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.

The objectives of the present study are to estimate the incidence of postoperative acute kidney injury (AKI) after radical nephrectomy with inferior vena cava (IVC) thrombectomy for renal cell carcinoma (RCC) based on the Acute Kidney Injury Network (AKIN) criteria, to investigate the risk factors for postoperative AKI, and to define the association between postoperative AKI and clinical outcome in patients undergoing such a surgery. ⋯ The incidence of postoperative AKI in patients with RCC and IVC thrombus was considerable. Intraoperative management seems to influence the risk of AKI after surgery; particularly, the longer the IVC clamping time, the higher the risk of postoperative AKI. Postoperative AKI was associated with postoperative CKD (P = .031), prolonged hospitalization (P = .047), and increased long-term mortality (1 year after surgery).
