NCT05698979

Brief Summary

The main objective is to assess the feasibility of treatment by injecting botulinum toxin A into the hand or foot of patients with signs of critical ischemia secondary to Buerger's disease. The injection of botulinum toxin A is carried out at the end of a single session during an hospitalization. Furthermore, tolerance and effects on the disease are evaluated at 1, 3 and 6 months post injections.

Outcome Measures

Primary Outcomes (1)

  • Feasibility in Number of patients

    The feasibility criterion corresponds to the number of patients who actually received the planned injections within the defined time limits, among the patients who should have received the injection according to the criteria of the protocol.

    through study completion, an average of 18 months

Secondary Outcomes (4)

  • tolerance of participants

    during injection

  • tolerance of participants

    2 hours after injection

  • tolerance during injection

    during injection

  • tolerance after injection

    2 hours after injection

Study Arms (1)

drug administration

EXPERIMENTAL

Botox Injection

Drug: BOTOX INJECTION

Interventions

The patient will be treated with a single session with botulinum toxin A injections at the hospital, and the judgmental criteria will be assessed at 1, 3 and 6 months post injections. The injections will be made in 4 injection points at the palmar or distal plantar fold, at the level of the neurovascular beams, 2h after topical anesthesia by lidocaine cream under occlusion, associated or not with nitrous oxide inhaled at the time of the injections (BOTOX® 100 U). In the event of multiple lesions, a single limb is injected based on clinical severity (ulcer, gangrene) and ischemia parameters (lowest TCPO2).
