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 ...

Maximizing Neurovascular Outcomes of Facial Transplantation: A Comprehensive Review

Clinical Anatomy, EarlyView.
ABSTRACT Facial transplantation is a division of reconstructive surgery which aims to improve the function and appearance of a face that has endured severe disfigurement. Currently, the face transplant procedure uses allogenic tissue, harvested from a brain‐dead donor, to replace damaged facial components.

A Novel Anatomical Description of the Normal Terminal Fibular Artery and the Terminal Fibular Window: Radiological Findings and Surgical Implications

Clinical Anatomy, EarlyView.
ABSTRACT A novel anatomical description and radiological finding, related to the anatomical course of the terminal fibular artery (FibA) was recently reported. In the article, the authors found the terminal FibA to change its course, from being posterior and medial to the fibula to surface anteriorly and laterally before residing below the tibiofibular

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 ...

Vascular Testing to Overcome Anatomical Contraindication: Fibula Free Flap in Bilateral Peronea Arteria Magna

Head &Neck, EarlyView.
ABSTRACT Background Peronea arteria magna (PAM) is an established contraindication for fibula free flap due to concern for vascular compromise of the lower leg. Methods This is a case of a 74‐year‐old male with a history of multiply recurrent oral cavity cancer who had undergone prior free flap reconstruction who presented with a new oral cavity ...

Investigating Associations Between Signal Intensity of Silent MR Angiography and Hemodynamic Information From 4D Flow MRI in Brain Arteriovenous Malformation

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Whether signal intensity (SI) on Silent MRA reflects hemodynamics in brain arteriovenous malformations (BAVMs) is unclear. Objectives To evaluate the relationship between Silent MRA SI and 4D flow‐derived hemodynamic parameters and examine whether Silent MRA‐based metrics are associated with symptomatic hemorrhage in BAVM.
