Management of Vasospastic Disorders with Botulinum Toxin A

Abstract

Hand injection of botulinum toxin A appears to be an effective treatment for intractable digital ulcerations and rest pain in patients with severe vasospastic disorders. Because of the complexity of surgical digital artery sympathectomy along with its associated high risk of persistent symptoms, the authors conclude that the therapeutic use of botulinum toxin A injections represents an attractive alternative therapy.
