Abstract:
Raynaud's phenomenon is often accompanied by pain, digital ulceration and compromised daily activities. Pharmacological therapy or sympathectomies have been administered to diminish these symptoms but existing treatments are not invariably efficacious. A recent case series has described the use of botulinum toxin type A in the treatment of Raynaud's phenomenon. We report two patients with severe or mild Raynaud's phenomenon who were injected with BTX-A; both of whom experienced clinical and image improvement after treatment.
