Area of Science:

Microsurgery
Reconstructive Surgery
Vascular Surgery

Background:

Mangled fingers with damaged common digital arteries pose significant replantation challenges.
Limited tissue availability complicates surgical repair in these cases.

Observation:

A novel technique involved anastomosing adjacent digital arteries to the amputated finger's artery.
Two veins were anastomosed per finger, and a skin pedicle was created from adjacent fingers.
Detachment occurred 4 weeks postoperatively.

Findings:

The study achieved a 100% survival rate for replanted fingers.
Excellent functional results included mean total active motion of 191.4°, mean static 2-point discrimination of 8 mm, and mean grip strength of 35.3 kg.

Implications:

Cross-finger revascularization is a viable and safe alternative for mangled finger salvage.
This technique offers a good functional prognosis for patients with damaged digital arteries.
