Presented in the article are clinical cases of successful totally percutaneous endovascular repair of the infrarenal portion of the abdominal aorta using the Ovation Prime ultra-low profile stent graft in high-surgical-risk patients, yielding good immediate and short-term results, thus demonstrating new possibilities in endovascular treatment of aneurysms of the infrarenal portion of the abdominal aorta.

Article Synopsis
- - Hemorrhage is the main cause of preventable death in trauma situations, leading to military and civilian advancements in medical practices, particularly through the use of tourniquets to manage extremity bleeding and save lives.
- - While tourniquets have significantly decreased deaths from bleeding in military settings, noncompressible hemorrhage still poses a major risk, especially before patients receive definitive medical care.
- - The study explores using a small, disposable pressure monitor during resuscitative endovascular balloon occlusion of the aorta (REBOA) to enhance blood pressure monitoring, facilitate better resuscitation practices, and reduce the need for blood products in extreme environments.
Anatomic Patterns of Distribution of the Renal Arteries' Origin from the Aorta.

Background: To characterize the variation of the renal arteries' origin from the aorta, through examination of computed tomography angiographies (CTAs) in a cohort of patients, and to evaluate any gender-related difference.
Methods: CTA of the thoracoabdominal district in patients with a nondilated aorta (group A), patients with aortic aneurysm involving the origin of splanchnic and/or renal vessels (group B), and patients with abdominal aortic aneurysm (group C), were retrospectively analyzed. The diameter and angles of emergence (axial and craniocaudal) of the renal arteries were measured, as well as their mutual distance, and the distance between the renal vessels and the superior mesenteric artery/the aortic bifurcation.
Induction of Controllable Vortical Flow in a Dual-Stenosis Aorta Model: A Replication of Disordered Eddies Flow in Aneurysms.

This paper presents a two-stenosis aorta model mimicking vortical flow in vascular aneurysms. More specifically, we propose to virtually induce two adjacent stenoses in the abdominal aorta to develop various vortical flow zones post stenoses. Computational fluid dynamics (CFD) simulations were conducted for the virtual two-stenosis model based on physiological and anatomical data (i.

For pheochromocytoma and paraganglioma (PPGL), the efficacy of percutaneous ablative therapies in achieving control of metastatic tumors measuring <3 cm had been demonstrated in only few reports, and intraoperative radiofrequency ablation (RFA) of locally invasive primary PPGLs has not been reported. We presented the case of a 31-year-old man who had a 9-cm functioning unresectable PPGL. He was treated with 13 cycles of cytotoxic chemotherapy without objective tumor response, according to the Response Evaluation Criteria in Solid Tumors (RECIST).

Purpose: The purpose was to describe a technique to promote false lumen (FL) thrombosis in post-dissection thoracoabdominal aortic aneurysms (PD-TAAAs) managed by fenestrated/branched endografting (F/B-EVAR).
Technique: A 5/6Fr-90 cm length sheath is advanced from the true lumen (TL) to FL through the most distal entry tear of the infrarenal aorta or iliac arteries. It is parked in the most cranial portion of the FL in the thoracic aorta.
