Limited microsurgical arteriolysis for complications of digital vasospasm

Twenty-two digits in seven patients with chronic digital vasospasm were surgically treated after failed medical management. All patients complained of severe ischaemic pain. Chronic digital tip ulceration was present in seven digits and dry gangrene in one. Following surgical microarteriolysis all digital ulcers healed completely. Severe digital ischaemic pain was significantly improved in all digits and completely resolved in 19 of 22 digits.
