The Prevalence of Financial Conflict of Interest Disclosures by Endovascular Specialists on X (Twitter).

Purpose: To evaluate conflicts of interest (COIs) among interventional radiologists and related specialties who mention specific devices or companies on the social media (SoMe) platform X, formerly Twitter.

Materials And Methods: In total, 13,809 posts between October 7, 2021, and December 31, 2021, on X were evaluated. Posts by U.

Balancing Safety and Efficacy to Determine the Most Suitable Size of Imaging-Visible Embolic Microspheres for Bariatric Arterial Embolization in a Preclinical Model.

Objectives: To identify the most suitable size of imaging-visible embolic agents with balanced safety and efficacy for bariatric arterial embolization (BAE) in a preclinical model.

Materials And Methods: Twenty-seven pigs were divided into 3 cohorts. In Cohort I, 16 pigs were randomized to receive (n = 4 each) 40-100-μm microspheres in 1 or 2 fundal arteries, 70-340-μm radiopaque microspheres in 2 fundal arteries, or saline.

Identifying the Ideal Target Vessel Size for Bariatric Embolization: Histologic Analysis of Swine and Human Gastric Fundi.

This study aimed to identify the ideal arteriole size to target in bariatric embolization, with the goal of maximizing weight loss efficacy while maintaining patient safety. Although all published clinical trials of bariatric embolization have used embolic microspheres that were at least 300 μm in diameter, optimal weight loss outcomes have been achieved safely in swine using 50-μm embolics. Human fundal remnants from bariatric surgery were compared with swine fundal sections after bariatric embolization with 50-μm embolic microspheres to assess the ideal fundal vessel size for bariatric embolization.

Preprocedure CT Findings of Right Heart Failure as a Predictor of Mortality After Transcatheter Aortic Valve Replacement.

Objective: The purpose of this study is to determine whether imaging features of right heart failure seen on CT performed before transcatheter aorta valve replacement (TAVR) predict poor outcomes after the procedure.

Materials And Methods: We retrospectively evaluated findings on CT performed before TAVR for 505 consecutive patients seen from 2014 to 2018. Of these patients, 300 underwent TAVR.

Percutaneous Transarterial Stent Placement in a Transplant Liver Hepatic Artery Complicated by Angioplasty Balloon Rupture and Fragmentation.

The incidence of posttransplant hepatic arterial stenosis (HAS) has been reported in 5 to 10% of orthotopic liver transplants and, left untreated, can lead to hepatic arterial thrombosis. Most vascular complications develop less than 3 months after initial transplant, with thrombosis representing over half of all complications. There has been a trend toward minimally invasive, endovascular techniques for treating HAS with angioplasty and stenting.

Intracavitary Coronary Artery: An Unusual Coronary Anomaly.

Purpose: A few case reports of intracavitary coronary arteries (ICCA) have been reported and only a single case series on the coronary computed tomography angiography (CCTA) prevalence rate of ICCA of the right coronary artery (RCA). We describe several cases of ICCA that were noted incidentally and also determine the overall prevalence rate of anomalous ICCA.

Materials And Methods: A retrospective analysis of ICCA was performed consisting of consecutive CCTA cases as well as a group of ICCA from teaching files.

Current and cutting-edge interventions for the treatment of obese patients.

The number of people classified as obese, defined by the World Health Organization as having a body mass index ≥30, has been rising since the 1980s. Obesity is associated with comorbidities such as hypertension, diabetes mellitus, and nonalcoholic fatty liver disease. The current treatment paradigm emphasizes lifestyle modifications, including diet and exercise; however this approach produces only modest weight loss for many patients.
