The authors describe a case of partial necrosis of the tip of the thumb caused by a peripheral microembolism of a collateral artery of the thumb at the time of a myocardial infarction and complicated by peripheral microembolism of the collateral artery. The reconstruction of the pulp was achieved with an island flap from the same finger following O'Brien method, which is often used in traumatology. In this particular case the skin island, usually supplied by both digital arteries, had one pedicle only, since the other one was thrombosed for about 1 cm in lenght. However, owing to the excellent blood supply of the flap, a good repair was obtained despite an anaerobic infection. The newly obtained finger-tip, seen at post-opchecks, is adequately convered, there is no rigidity of the interphalangeal joint nor signs of recurrence of the infection.
