Background: Alterations in cellular metabolism affect cancer survival and can manifest in metrics of body composition. We investigated the effects of various body composition metrics on survival in patients with glioblastoma (GBM).
Methods: We retrospectively analyzed patients who had an abdominal and pelvic computed tomography (CT) scan performed within 1 month of diagnosis of GBM (178 participants, 102 males, 76 females, median age: 62.
Recurrent peripheral ischemia following endovascular repair of an infrarenal aortic aneurysm: what did we miss?

We document a case of a 75-year-old patient with a history of hypercholesterolemia and hypertension, who underwent endovascular aortic repair (EVAR) for an infrarenal abdominal aortic aneurysm (AAA) with common iliac artery ectasia. Despite an initially successful procedure, the patient experienced recurrent episodes of acute limb ischemia in his right leg. Subsequent imaging revealed thrombus formation distal to the stent graft, constituting a potential source of embolization, which warranted a reevaluation of the treatment strategy.

, an Ascomycetes fungus, is the responsible pathogen for histoplasmosis. Although often asymptomatic, around 1% of cases progress to disseminated infection. Endovascular graft infections with this fungus have been reported, particularly on abdominal aortic or aortofemoral bypass grafts.

Purpose: To explore the information in routine digital subtraction angiography (DSA) and evaluate deep learning algorithms for automated identification of anatomic location in DSA sequences.
Methods: DSA of the abdominal aorta, celiac, superior mesenteric, inferior mesenteric, and bilateral external iliac arteries was labeled with the anatomic location from retrospectively collected endovascular procedures performed between 2010 and 2020 at a tertiary care medical center. "Key" images within each sequence demonstrating the parent vessel and the first bifurcation were additionally labeled.
Post-closure Technique for Access Hemostasis During Emergency Endovascular Repair in Ruptured Abdominal Aortic Aneurysms: Technical Note on a Preliminary Experience.

Department of Vascular and Endovascular Surgery, The Affiliated Suzhou Hospital of Nanjing Medical University, 242 Guangji Road, Gusu District, Suzhou, 215000, China.
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.
