Vascular Insufficiency/Chronic Ischemia in the Upper Extremity-Botulinum Toxin Type A in the Treatment of Raynaud’s Phenomenon

Botulinum Toxin Type A in the Treatment of Raynaud’s Phenomenon

Pdf Summary

This study examines the use of botulinum toxin type A (onabotulinumtoxinA) in the treatment of Raynaud's phenomenon, a condition characterized by vasospastic disorders in the hands and feet. The study reviews patients who were injected with onabotulinumtoxinA and analyzes the outcomes. Laser Doppler scans were used to measure perfusion before and after injection. The results showed that the majority of patients experienced improved vascularity and relief of pain after the injection. Laser Doppler scans also showed improvement in perfusion. The study concludes that botulinum toxin can improve hand perfusion by directly injecting it around the neurovascular bundles. Further research is needed to understand the specific mechanism of action in relieving vasospasm and alleviating pain.
