Tremendous efforts have been initiated to elucidate the molecular and pathophysiological characteristics of abdominal aortic aneurysm (AAA) disease, which is a significant contributor to morbidity and mortality in the Western world. Recently, a novel class of small noncoding RNAs, called microRNAs, was identified as important transcriptional and posttranscriptional inhibitors of gene expression thought to simultaneously "fine tune" the translational output of multiple target messenger RNAs (mRNAs) by promoting mRNA degradation or inhibiting translation. Several research groups were able to identify the miR-29 family, and miR-29b in particular, as crucial regulators of-not only vascular fibrosis-but also cardiac-, kidney-, liver-, and skin-fibrosis. The current review briefly points out data indicating a causal role for miR-29 in various diseases, while focusing on its potential benefit during AAA initiation and propagation.

Fenestrated Anaconda Endograft for the Treatment of Complex Aortic Aneurysms: Systematic Review and Meta-Analysis.
J Endovasc Ther
January 2025
Department of Vascular Surgery, Swiss Aortic Center Bern, Inselspital, University Hospital of Bern, University of Bern, Bern, Switzerland.
Purpose: To perform a systematic review and meta-analysis of the outcomes of Anaconda fenestrated endograft for the treatment of complex abdominal aortic aneurysms (cAAA).
Material And Methods: A systematic search of all the literature reported until May 2024 was performed according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. The pooled 30-day mortality rate, technical success rate, reintervention rate as well as bridging stent occlusion rate, and corresponding 95% confidence intervals (CIs) were estimated using fixed or random effect methods.
Design of a Cost-Effective Ultrasound Force Sensor and Force Control System for Robotic Extra-Body Ultrasound Imaging.

Ultrasound imaging is widely valued for its safety, non-invasiveness, and real-time capabilities but is often limited by operator variability, affecting image quality and reproducibility. Robot-assisted ultrasound may provide a solution by delivering more consistent, precise, and faster scans, potentially reducing human error and healthcare costs. Effective force control is crucial in robotic ultrasound scanning to ensure consistent image quality and patient safety.

A type 2 endoleak (EL2) remains the most prevalent complication of endovascular aortic repair (EVAR) for an abdominal aortic aneurysm (AAA). We conducted a retrospective, single-center analysis, including patients who underwent embolization for an isolated EL2 after EVAR. The study population was stratified into two groups: Group A, consisting of patients whose EL2 resolved after the first embolization procedure, and Group B, consisting of those with refractory EL2 (rEL2).

Desmoid tumors are a rare entity, especially in the pediatric population. There are no reports of such a tumor in newborns. They are associated with high rates of morbidity and mortality, even though they are benign soft tissue tumors.

Background: Undiagnosed and untreated atherosclerotic renal artery stenosis (ARAS) can result in end-stage kidney disease (ESKD). To obtain an accurate diagnosis, it is crucial to recognize the symptoms and signs suggesting renal artery stenosis (RAS) and perform appropriate diagnostic and treatment procedures afterward.
Case Presentation: We present a case of a 60-year-old female patient with hypertensive crisis, acute heart failure (HF), and pulmonary edema as the initial signs of acute kidney injury (AKI) caused by right RAS and left renal artery occlusion in the presence of severe aortic atherosclerosis revealed on computed tomography angiography (CTA) of the abdomen.
