Purpose: Fingertip replantation is a challenging and technically demanding procedure. A variety of venous drainage techniques have been attempted for successful fingertip replantation. We present a new venous drainage technique, known as serial multifocal incision for fingertip replantation. Methods: Between 2006 and 2014, we performed 94 fingertip replantations without vein anastomosis. Eighty of the patients were male, and 14 were female, with an overall mean age of 42 years (range: 8–67 years). All patients suffered amputations distal to the distal phalanx joint (Ishikawa subzone I, II, or III). We performed only artery anastomosis. To relieve venous congestion, we incised the fingertip 2–3 mm using a number 11 scalpel blade and allowed the vein to drain naturally. We made small serial incisions every 2–3 days for 1 week. Results: The overall success rate for this procedure was 90%, with 85 surviving digits. Two patients with partial necrosis and nine patients with complete loss needed a second operation. Two patients received blood transfusions with an average of 1.5 units, but both had an accompanying injury at another site. No one complained of nail deformity or wound infection. Conclusions: Various external bleeding techniques have been reported to yield good results. The serial stab incision venous drainage technique is a modified fish-mouth external bleeding technique that overcomes the disadvantages of published methods. This technique is simple, allows for easy control of venous drainage, and reduces the need for blood transfusions compared to other venous drainage techniques that cause large amounts of bleeding. We propose a new method, the serial stab incision venous drainage technique, which is effective and associated with high rates of survival.
