Abstract This study was performed to review our 16‐year experience in acute finger ischemia. A review of the literature was also performed. A retrospective chart review of 17 patients, 14 men and 3 women, was conducted. Etiologies were ulnar aneurysm in 11 cases, atrial fibrillation in five cases and thoracic outlet syndrome in one case. Upto the palmar superficial arch, embolus due to atrial fibrillation or thoracic outlet syndrome could be loosened by a Fogarty catheter. In cases of aneurysm of the ulnar artery, we performed each time an aneurysm resection followed by direct anastomose alone, while three patients had additional grafts: artery graft (epigastric artery) or reversed vein grafts (superficial forearm vein). Microsurgical dissection of the digital collateral arteries enabled us to perform a thrombectomy. The transversal arteriotomies were closed after the collateral arteries were washed. The immediate perfusion of digit after the reconstruction of the aneurysm was each time excellent. The disoccluded vessels, investigated by Allen testing and Doppler ultrasound, were all patents. Two patients suffered from a small ulcer of the small fingertip that disappeared after 2 weeks. One patient had a 30° ischemic flexion contracture in the metacarpophalangeal joint and 25° flexion contracture in the proximal interphalangeal joint of the third digit. With regards to long‐term outcomes, no secondary amputations were necessary and there was no recurrence after a mean follow‐up of 10.7 years. Diagnostic of acute digital ischemia is often neglected. An early recognition and an aggressive microsurgical treatment are necessary to ensure low morbidity. © 2009 Wiley‐Liss, Inc., Microsurgery, 2010.
