The choice of vascular access in hemodialysis pediatric patients can be challenging, due to the small diameter of vessels. In the last 19 years, 38 arteriovenous fistulas (AVF) for hemodialysis have been created on 21 patients; 25 of them were radio-cephalic AVF. The evaluation of the vessels was, in the majority of cases, done by clinical criteria. A local anesthesia was used in all surgical procedures. The percentage of early AVF failure was 24%. Long-term AVF survival was 97%, 65% and 55% at respectively 1, 3 and 5 years. Our data indicate that even in pediatric patients the radio-cephalic fistula is the first choice surgical procedure.

Gen Thorac Cardiovasc Surg Cases
January 2025
Department of Surgery II, Faculty of Medicine, Yamagata University, Yamagata, Japan.
Background: With advancements in minimally invasive thoracic surgery techniques, such as video-assisted thoracoscopic surgery and robotic surgery, the design of vascular staplers has evolved to meet the requirements of these procedures. Consequently, newer generations of automatic staplers with improved handling and reduced size have been introduced, such as two-row staplers, which are more maneuverable and less bulky than their three-row counterparts.
Case Presentation: A 68-year-old man with lung cancer underwent a right middle and lower lobectomy due to tumor invasion into the central middle bronchial trunk, rendering the preservation of the middle lobe impossible.

Purpose: The AVeNEW Post-Approval Study (AVeNEW PAS) follows upon results from the AVeNEW IDE clinical trial and was designed to provide additional clinical evidence of safety and effectiveness using the Covera™ Vascular Covered Stent to treat arteriovenous fistula (AVF) stenoses in a real-world hemodialysis patient population.
Materials And Methods: One hundred AVF patients were prospectively enrolled at 11 clinical trial sites in the USA and treated with the covered stent after angioplasty of a clinically significant target stenosis. The primary safety outcome was freedom from any adverse event that suggests the involvement of the AV access circuit evaluated at 30 days.

Purpose: To describe the downsizing post-closure technique for access hemostasis during emergency endovascular repair (EVAR) in ruptured abdominal aortic aneurysms (RAAA).
Materials And Methods: A cohort of eight patients underwent emergency EVAR through 16 femoral access sites for infrarenal RAAA. The downsizing post-closure technique, which involves a reduction in the size of the large-bore access by advancing a 10F sheath, was consistently applied.

Introduction: Cardiovascular diseases (CVDs) present differently in women and men, influenced by host-microbiome interactions. The roles of sex hormones in CVD outcomes and gut microbiome in modifying these effects are poorly understood. The XCVD study examines gut microbiome mediation of sex hormone effects on CVD risk markers by observing transgender participants undergoing gender-affirming hormone therapy (GAHT), with findings expected to extrapolate to cisgender populations.

Introduction: MODY2 (maturity-onset diabetes of the young type 2, MIM125851) is a monogenic diabetes with an autosomal dominant transmission caused by a variant of the gene. MODY2 is often confused with type 1 or type 2 diabetes, but despite a slightly elevated blood glucose level, it does not induce long-term vascular complications, nor does it require pharmacological treatment. Genetic testing for the diagnosis of MODY2 is currently reserved for genetic specialists and some physicians.
