Nerve sonography to detect intraneural microvascularity in patients with peripheral neuropathy.
Clin Neurophysiol
October 2024
Department of Neurology, Nippon Medical School, Tokyo, Japan.
Article Synopsis
- - The study aimed to assess blood flow in peripheral nerves of patients with peripheral neuropathy using nerve sonography techniques.
- - Researchers divided patients into two categories: inflammatory neuropathies (like Guillain-Barre syndrome) and non-inflammatory neuropathies, and measured blood flow in the median and ulnar nerves.
- - Findings indicated that patients with inflammatory neuropathy had significantly higher intraneural blood flow compared to those with non-inflammatory neuropathy, suggesting that blood flow evaluation could aid in diagnosing peripheral neuropathy.
Trigeminal neuralgia (TN) caused by venous compression presents challenges in surgical management, unlike the arterial type. Preoperative diagnostic certainty regarding venous etiology and anatomical relationships is crucial for surgical success. We discuss a case of TN caused by a vein passing through the nerve that was challenging to visualize on conventional MRI and was treated successfully by leveraging information from modern surgical simulation technology with 3D computer graphics.

Introduction: Superb microvascular imaging (SMI) is an advanced ultrasound technique that portrays microcirculation. Its clinical applications have been studied in various diseases, including carpal tunnel syndrome (CTS) i.e.

Several studies have demonstrated elevated intraneural vascularity in severe neuropathy compared with healthy subjects, where intraneural vascularity is considered predominantly undetectable. The aim of this study was to assess and quantify intraneural vasculature by superb microvascular imaging (SMI) in healthy volunteers in the median, ulnar and common peroneal nerve.

May 2022
Department of Neurosurgery, Shanghai Tenth People's Hospital of Tongji University, Shanghai, China.
Background: Microvascular decompression (MVD) surgery is the treatment of choice for trigeminal neuralgia (TGN). However, decompression becomes difficult when the offending vessel penetrates the trigeminal nerve root.
Objective: To estimate the rates and patterns of different types of intraneural offending vessels in patients with TGN for MVD and to discuss respective management strategies.
