Measuring the palpable pulsatility length as a physical examination test in defining the severity of inflow stenosis for hemodialysis fistulas

BMC Nephrology, 2019
Background Pulsatility is an important property of hemodialysis arteriovenous fistulas (AVF) and can be perceived by the fingers as a gradual decrease in strength downstream from the anastomosis along the main trunk of the fistula.

Transvenous embolization of a Borden III middle cranial fossa dural arteriovenous fistula through the vein of Trolard and superficial middle cerebral vein: A technical case report

Radiology Case Reports
Endovascular treatment for isolated dural arteriovenous fistula (DAVF) in the middle cranial fossa (MCF) with pure cortical venous drainage poses challenges, including the absence of a safe access route for transvenous embolization (TVE) and the risk of ...

Network Disconnection Syndrome in Unruptured Brain Arteriovenous Malformations: A Multimodal Connectome Study

CNS Neuroscience &Therapeutics, Volume 32, Issue 3, March 2026.
This study challenges the traditional reliance on lesion size, demonstrating that cognitive impairment in unruptured bAVMs is fundamentally driven by global white matter disconnection. We identified a critical “structure–function decoupling,” where compensatory reorganization fails once the underlying structural scaffold collapses.
