ABSTRACT
Ischaemic fingers, a rare, generally chronic disease, may sometimes be acute, requiring emergency surgical treatment. Five cases are reported: 3 acute and 2 chronic. The 3 cases of acute ischaemia occurred in the context of cardiac arrhythmias in 2 cases and an aneurysm of the ulnar artery in 1 case. Treatment consisted of 2 thrombectomies with microsurgical digital sympathectomy thrombectomies with microsurgical digital sympathectomy and resection of the aneurysm. Complete clinical and functional recovery was obtained in these three cases. The 2 cases of chronic ischaemia were due to diabetes and Buerger's disease. In both cases, medical treatment was followed by thoracic sympathectomy with secondary resection of necrotic tissue as required. In conclusion, the prognosis in the acute cases depends on the rapidity of correction of the arterial obstruction associated with digital sympathectomy. In the case of chronic ischaemia, the clinical course depends on the efficacy of medico-surgical treatment and the severity of the underlying disease.
