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.

Advanced Wound, Ischemia, and foot Infection stage is associated with poor outcomes in the BEST-CLI trial.

Objective: Wound, Ischemia, and foot Infection (WIfI) staging was established to provide objective classification in patients with chronic limb-threatening ischemia (CLTI) and to predict 1-year major amputation risk. Our goal was to validate WIfI staging using data from the Best Endovascular vs Best Surgical Therapy in Patients with CLTI (BEST-CLI) trial.

Methods: Data from the BEST-CLI Trial, a prospective randomized trial comparing surgical revascularization (OPEN) and endovascular revascularization (ENDO), were used to assess the association of WIfI stage on long-term outcomes in an intention-to-treat analysis.

Impact of skin closure with staples vs sutures on perioperative outcomes following lower extremity bypass surgery.

Objective: Wound complications are one of the major sources of morbidity after open vascular procedures, especially lower extremity bypass (LEB). The preferred skin closure method is based on surgeon preference. Because no data clearly demonstrates the superiority of one method over the other, we aimed to compare outcomes of staples vs sutures for skin closure after LEB.

A Novel Preoperative Risk Score to Identify Patients at High Risk for Nonhome Discharge after Elective Open Abdominal Aortic Aneurysm Repair.

Background: Nonhome discharge (NHD) to a rehabilitation or skilled nursing facility after vascular surgery is poorly described despite its impact on patients. For home-dwelling patients undergoing elective surgery, the need for postoperative NHD can have meaningful implications on quality of life, long-term outcomes, and health-care spending. Understanding postsurgical NHD risk is essential to preoperative counseling and shared decision making.

The impact of diabetes mellitus on the outcomes of revascularization for chronic limb-threatening ischemia in the BEST-CLI trial.

Objective: Several observational studies have demonstrated an association between diabetes mellitus (DM) and above-ankle amputation after lower extremity revascularization (LER). However, data from prospective randomized trials is lacking. This analysis compares the outcomes of patients with and without DM enrolled in the Best Endovascular vs Best Surgical Therapy in patients with Chronic Limb-Threatening Ischemia (BEST-CLI) trial.

Prosthetic conduits have worse outcomes compared with great saphenous vein conduits in femoropopliteal and infrapopliteal bypass in patients with chronic limb-threatening ischemia.

Objective: Single segment great saphenous vein (SSGSV) traditionally has been considered the gold standard conduit for infrainguinal bypass. There are data supporting similar outcomes with prosthetic femoral-popliteal bypass. Moreover, some investigators have advocated for prosthetic conduit for femoral tibial bypass when GSV is inadequate or unavailable.

Antithrombotic Strategies for Patients With Peripheral Artery Disease: JACC Scientific Statement.

Patients with peripheral artery disease (PAD) experience major cardiovascular and limb events. Antithrombotic strategies including antiplatelets and anticoagulants remain a cornerstone of treatment and prevention. Recent trials have shown heterogeneity in the response to antithrombotic therapies in patients presenting primarily with PAD when compared to those presenting primarily with coronary artery disease.

Dynamic changes in proresolving lipid mediators and their receptors following acute vascular injury in male rats.

Acute vascular injury provokes an inflammatory response, resulting in neointimal hyperplasia (NIH) and downstream pathologies. The resolution of inflammation is an active process in which specialized proresolving lipid mediators (SPM) and their receptors play a central role. We sought to examine the acute phase response of SPM and their receptors in both circulating blood and the arterial wall in a rat angioplasty model.

Early Opioid Use and Postoperative Delirium Following Open Abdominal Aortic Aneurysm Repair.

Background: Postoperative delirium is a common complication following open abdominal aortic aneurysm repair (OAR). Opioids have been found to contribute to delirium, especially at higher doses. This study assessed the impact of early postoperative opioid analgesia on postoperative delirium incidence and time to onset.

The impact of revascularization strategy on clinical failure, hemodynamic failure, and chronic limb-threatening ischemia symptoms in the BEST-CLI Trial.

Objective: Sustained clinical and hemodynamic benefit after revascularization for chronic limb-threatening ischemia (CLTI) is needed to resolve symptoms and prevent limb loss. We sought to compare rates of clinical and hemodynamic failure as well as resolution of initial and prevention of recurrent CLTI after endovascular (ENDO) vs bypass (OPEN) revascularization in the Best-Endovascular-versus-best-Surgical-Therapy-in-patients-with-CLTI (BEST-CLI) trial.

Methods: As planned secondary analyses of the BEST-CLI trial, we examined the rates of (1) clinical failure (a composite of all-cause death, above-ankle amputation, major reintervention, and degradation of WIfI stage); (2) hemodynamic failure (a composite of above-ankle amputation, major and minor reintervention to maintain index limb patency, failure to an initial increase or a subsequent decrease in ankle brachial index of 0.

Infrapopliteal Endovascular Interventions for Claudication Are Associated with Poor Long-Term Outcomes in Medicare-Matched Registry Patients.

Background: There are limited data supporting or opposing the use of infrapopliteal peripheral vascular interventions (PVI) for the treatment of claudication.

Objectives: We aimed to evaluate the association of infrapopliteal PVI with long-term outcomes compared with isolated femoropopliteal PVI for the treatment of claudication.

Methods: We conducted a retrospective analysis of all patients in the Medicare-matched Vascular Quality Initiative database who underwent an index infrainguinal PVI for claudication from January 2004-December 2019 using Cox proportional hazards models.

Quality of Life in Patients With Chronic Limb-Threatening Ischemia Treated With Revascularization.

Background: In the BEST-CLI trial (Best Endovascular Versus Best Surgical Therapy for Patients With Chronic Limb-Threatening Ischemia), a prespecified secondary objective was to assess the effects of revascularization strategy on health-related quality of life (HRQoL).

Methods: Patients with chronic limb-threatening ischemia were randomized to surgical bypass (Bypass) or endovascular intervention (Endo) in 2 parallel trials. Cohort 1 included patients with single-segment great saphenous vein; cohort 2 included those lacking suitable single-segment great saphenous vein.

Appropriateness of Care Measures: A Novel Approach to Quality.

The clinical judgment of a physician is one of the most important aspects of medical quality, yet it is rarely captured with quality measures in use today. We propose a novel approach using individualized physician benchmarking that measures the appropriateness of care that a physician delivers by looking at their practice pattern in a specific clinical situation. A prime application of our novel approach to appropriateness measures is the surgical management of peripheral artery disease and claudication.

Relevance of BEST-CLI trial endpoints in a tertiary care limb preservation program.

Objective: Major adverse limb event-free survival (MALE-FS) differed significantly by initial revascularization approach in the BEST-CLI randomized trial. The BEST-CLI trial represented a highly selected subgroup of patients seen in clinical practice; thus, we examined the endpoint of MALE-FS in an all-comers tertiary care practice setting.

Methods: This is a single-center retrospective study of consecutive, unique patients who underwent technically successful infrainguinal revascularization for chronic limb-threatening ischemia (2011-2021).

Secondary interventions following open vs endovascular revascularization for chronic limb threatening ischemia in the BEST-CLI trial.

Objectives: Patients undergoing revascularization for chronic limb-threatening ischemia experience a high burden of target limb reinterventions. We analyzed data from the Best Endovascular versus Best Surgical Therapy in Patients with Critical Limb Ischemia (BEST-CLI) randomized trial comparing initial open bypass (OPEN) and endovascular (ENDO) treatment strategies, with a focus on reintervention-related study endpoints.

Methods: In a planned secondary analysis, we examined the rates of major reintervention, any reintervention, and the composite of any reintervention, amputation, or death by intention-to-treat assignment in both trial cohorts (cohort 1 with suitable single-segment great saphenous vein [SSGSV], n = 1434; cohort 2 lacking suitable SSGSV, n = 396).

Predictors of amputation-free survival and wound healing after infrainguinal bypass with alternative conduits.

Objective: Inadequate vein quality or prior harvest precludes use of autologous single segment greater saphenous vein (ssGSV) in many patients with chronic limb-threatening ischemia (CLTI). Predictors of patient outcome after infrainguinal bypass with alternative (non-ssGSV) conduits are not well-understood. We explored whether limb presentation, bypass target, and conduit type were associated with amputation-free survival (AFS) after infrainguinal bypass using alternative conduits.
