Botulinum Toxin Injection for Functional Popliteal Artery Entrapment Syndrome

NCT03631966 · Status: WITHDRAWN · Phase: PHASE2 · Type: INTERVENTIONAL

Last updated 2021-03-08

No results posted yet for this study

Summary

Failure to adequately diagnose and treat patients with functional popliteal artery entrapment syndrome (PAES) leads to continued pain, loss of function and poor quality of life for many patients nationwide. Currently, the primary treatment for functional PAES involves muscle resection, sometimes involving large segments of muscle, which itself can lead to functional impairment. As such, a less invasive treatment for functional PAES is desirable. The focus of this work is to determine whether Botulinum toxin type A (BTX-A) injections into the gastrocnemius muscle can lessen the mechanical forces placed on the popliteal artery by the involved muscle, thereby improving symptoms caused by impaired distal blood flow.

Conditions

  • Functional Popliteal Artery Entrapment Syndrome
  • Popliteal Artery Entrapment Syndrome

Interventions

DRUG

Dysport

BTX-A (Dysport-Ipsen Inc.) will be injected into the proximal third of the medial and lateral gastrocnemius muscles of the symptomatic leg(s). Total dose per leg will be 400 units, 200 per injection site. Injections will be performed with the aid of real-time ultrasound (Sonosite, Bothwell, WA) guidance.
