Objective: Cyanoacrylate closure (CAC) is a minimally invasive technique for treating axial venous reflux. However, the incidence of serious adverse events (AEs) related to CAC is concerning. With an increasing number of patients undergoing CAC and insufficient safety data in Japan, this study aimed to investigate the safety profile of CAC, focusing on the types and incidence of AEs.

Arterial stiffening is associated with adverse cardiovascular patient outcomes; stiffness may also be associated with postsurgical events and has been suggested to be a fundamental mechanism in the pathogenesis of aortic aneurysms. Although open repair of aneurysms decreases aortic stiffness, implantation of a rigid endograft is associated with increased aortic stiffness after endovascular aneurysm repair (EVAR). This review provides an overview of aortic wall physiology and the contemporary understanding of aortic stiffness and its implications for patients undergoing abdominal aortic aneurysm repair.

Background: Endovascular aneurysm repair (EVAR) has revolutionized the treatment of abdominal aortic aneurysms by offering a less invasive alternative to open surgery. Understanding the factors that influence patient outcomes, particularly for high-risk patients, is crucial. The aim of this study was to determine whether machine learning (ML)-based decision tree analysis (DTA), a subset of artificial intelligence, could predict patient outcomes by identifying complex patterns in data.

Article Synopsis
  • The study investigates the neutrophil-lymphocyte ratio (NLR) as a potential predictor for overall mortality in patients undergoing thoracic endovascular aortic repair (TEVAR) for degenerative thoracic aortic aneurysm (TAA).
  • Researchers analyzed data from 103 patients treated with TEVAR over nine years, finding that higher NLR, alongside age and ischemic heart disease, correlates with increased mortality risk.
  • The optimal NLR cutoff identified for predicting all-cause mortality was 3.48, indicating that elevated NLR can help identify patients at higher risk after the procedure.

Article Synopsis
  • * The CAC-AE survey collected data from 1,030 authorized institutions, reporting 16 cases of proximal deep vein thrombosis, 3 cases of pulmonary embolism, and various other complications.
  • * The findings highlighted a total of 299 cases of localized phlebitis or allergic reactions, with one postoperative death linked to pulmonary embolism, aiming to present real-world data on CAC-related AEs in Japan.
