Abstract

This case report aims to point out the importance of having in mind anatomical variation in the blood supply to the hand even in emergency settings. A 39-year-old patient presented at our emergency department with a wound on the distal anterolateral third of the left forearm with skin loss, degloving injury of the thumb starting from the 1st metacarpal, exposure of the proximal two thirds of the 1st metacarpal bone, and both radial and ulnar digital arteries of the thumb damaged. A 10-cm-long vein graft was anastomosed in termino-later fashion between the dorsal branch of the radial artery and the uninjured distal part of the ulnar collateral digital artery of the thumb, successfully re-establishing its blood supply. Starting from the 1st postoperative day, the thumb was warm and pink while the other fingers were pale and capillary filling was absent. An urgent arteriography of the left upper extremity demonstrated the presence of normal radial artery, hypoplastic ulnar artery, dominant median artery, and absence of vascularization of the 2nd, 3rd, 4th, and 5th fingers. By the end of 2nd week, the patient underwent amputation of the four fingers at the distal metacarpal level. Anatomical anomalies of hand arterial blood supply are not uncommon, even though rarely reported in literature. Therefore, an instrumental study should be performed before attempting any arterial intervention even in emergency settings. Nevertheless, further studies should be performed to identify ready-to-use tools to make surgeons aware of any anatomic variations in order to avoid such complications.

Level of Evidence: Level V, therapeutic study.
