Incidental Visualization of Hypertrophic Vasa Nervorum in a Patient with Peripheral Vascular Disease

Pdf Summary

The article discusses a case of a 76-year-old male with limb ischemia and a complex medical history. Due to the patient's medical history, the decision was made to perform femoral and popliteal sciatic nerve blocks under real-time ultrasound guidance. The ultrasound images revealed hypertrophic vasa nervorum within the nerves. Complete surgical anesthesia was achieved with the nerve blocks, and the patient had an uneventful hospitalization and was discharged for rehabilitation. The discussion focuses on vasa nervorum, which are blood vessels that provide blood supply to nerves. The article explains that vasa nervorum can become inflamed and compromised in cases of peripheral vascular disease, diabetes, infection, malignancy, or connective tissue disorders. In such cases, ischemia of the limb can cause inflammation of the vasa nervorum, leading to vasculitic neuropathy. The activation of inflammatory mediators can result in increased vascularity and enlarged vasa nervorum. The article provides images of the hypertrophic vasa nervorum in the femoral and popliteal sciatic nerves. The authors declare no potential conflicts of interest and received no financial support for the research. Informed consent has been obtained from the patient to publish this case report. No funding was provided for the research. Additional supplemental material is available online.
