Low rates of aortic surveillance imaging and clinical follow-up in patients with acute aortic dissection.

Objectives: Patients that survive acute aortic dissection (AD) remain at high risk of morbidity/mortality from structural changes of the aorta. Aortic surveillance is challenging, especially within a tertiary referral center. Our aim was to identify follow-up imaging and appointment rates, and factors associated with incomplete surveillance in patients with acute AD.

Large language models can accurately populate Vascular Quality Initiative procedural databases using narrative operative reports.

Objectives: Participation in the Vascular Quality Initiative (VQI) provides important resources to surgeons, but the ability to do so is often limited by time and data entry personnel. Large language models (LLMs) such as ChatGPT (OpenAI) are examples of generative artificial intelligence (AI) products that may help bridge this gap. Trained on large volumes of data, the models are used for natural language processing (NLP) and text generation.

Association of Intraoperative and Perioperative Transfusions with Postoperative Cardiovascular Events and Mortality After Infrainguinal Revascularization.

Background: Patients undergoing open or endovascular infrainguinal revascularization are at an elevated risk for postoperative cardiovascular complications due to high rates of comorbidities and the physiologic stress of surgery. Transfusions are known to be associated with adverse events but knowledge of specific risks associated with transfusion timing, product type, and long-term outcomes while accounting for preoperative cardiovascular risk factors is not well understood in this population. This study aimed to characterize the association of intraoperative and perioperative transfusion, anemia, and cardiovascular risk factors with cardiovascular events and mortality in patients undergoing infrainguinal revascularization.

Risk factors for venous thromboembolism after vascular surgery and implications for chemoprophylaxis strategies.

Objective: Venous thromboembolism (VTE) is an important cause of postoperative morbidity and mortality. However, the reported incidence after major vascular surgery has ranged from as low as 1% to >10%. Furthermore, little is known about optimal chemoprophylaxis regimens or rates of postdischarge VTE in this population.

Evolution of fenestrated/branched endovascular aortic aneurysm repair complexity and outcomes at an organized center for the treatment of complex aortic disease.

Background: Fenestrated/branched endovascular aneurysm repair (F/BEVAR) volume has increased rapidly, with favorable outcomes at centers of excellence. We evaluated changes over time in F/BEVAR complexity and associated outcomes at a single-center complex aortic disease program.

Methods: Prospectively collected data of all F/BEVAR (definition: requiring ≥1 fenestration/branch), procedures performed in an institutional review board-approved registry and/or physician-sponsored investigational device exemption trial (IDE# G130210), were reviewed (11/2010-2/2019).

Preoperative functional status predicts 2-year mortality in patients undergoing fenestrated/branched endovascular aneurysm repair.

Background: Fenestrated/branched endovascular aneurysm repair (F/BEVAR) is a minimally invasive alternative for patients at high risk of open repair of complex aortic aneurysms. Nearly all investigative study protocols evaluating F/BEVAR have required a predicted life expectancy of >2 years for study inclusion. However, accurate risk models for predicting 2-year survival in this patient population are lacking.

Positional transient loss of consciousness and hemispheric deficits in the setting of severe four-vessel extracranial cerebrovascular disease.

Carotid artery stenosis typically causes hemispheric neurologic effects by atheroembolism. Nonhemispheric symptoms, such as syncope, are generally not attributable to extracranial carotid disease. This report describes a 62-year-old woman with severe bilateral carotid artery stenosis, right vertebral artery occlusion, and severe left vertebral artery stenosis who presented with transient loss of consciousness and unilateral weakness when upright.
