Varicocele due to renal arteriovenous malformation mimicking a renal tumor: a case report
Journal of Medical Case Reports, 2018 Background Renal arteriovenous malformation is an aberrant vascular connection between the renal artery and vein. Acquired renal arteriovenous malformation (arteriovenous fistulae) accounts for approximately 70% of renal arteriovenous abnormalities ...

Affinity Feature Strengthening for Accurate, Complete and Robust Vessel Segmentation [PDF]
arXiv, 2022 Vessel segmentation is crucial in many medical image applications, such as detecting coronary stenoses, retinal vessel diseases and brain aneurysms. However, achieving high pixel-wise accuracy, complete topology structure and robustness to various contrast variations are critical and challenging, and most existing methods focus only on achieving one or

The accessory renal arteries: A systematic review with meta‐analysis
Clinical Anatomy, EarlyView.Abstract The accessory renal arteries (ARAs) are a well‐described variant of the renal vasculature with clinical implications for radiologists, surgeons, and clinicians. The aim of the present systematic review with meta‐analysis was to estimate the pooled prevalence of ARAs, including their variant number, origin, and termination, and to highlight ...

Catheterization and Cardiovascular Interventions, EarlyView.ABSTRACT Background Venous outflow is the favored access for endovascular management of dialysis fistulas. However, transradial access (TRA) offers advantages in specific clinical scenarios. The study aims to compare the efficacy, feasibility, and safety of TRA and transvenous access (TVA) in the endovascular management of malfunctioning dialysis ...

Ultra-high-resolution subtraction CT angiography in the follow-up of treated intracranial aneurysms
Insights into Imaging, 2019 In subtraction CT angiography (CTA), a non-contrast CT acquisition is subtracted from a contrast-enhanced CTA acquisition. Subtraction CTA can be applied in the detection, classification, and follow-up of intracranial aneurysms and is advantageous over ...

Role of digital subtraction angiography in diagnosis of fibromusculardysplasia
Indian Journal of Vascular and Endovascular Surgery, 2021 Fibromuscular dysplasia (FMD) is a vascular disease characterized by abnormal arterial wall architecture, usually visualized angiographically as the classic “string of beads” sign.
