Reconstruction of circulation in the fingertip without vein repair in zone I replantation
Case series published in J Hand Surg Am (2008)
Abstract
PURPOSE: In fingertip replantation, adequate venous drainage is important for success. As the level of amputation becomes more distal, anastomosis of veins becomes more technically difficult. External bleeding is a common solution to venous congestion, but the process is burdensome because of duration of bleeding for 3 or more days after surgery. We present a new technique for reconstructing circulation without vein anastomosis in zone I replantation and analyze the outcomes of this technique in terms of eliminating external bleeding and of a high survival rate of the replanted digits. METHODS: Between 1997 and 2007, we performed 120 replantations in 112 patients (83 male and 29 female; mean age, 33 years; range, 3-54 years). All were zone I amputations, based on the Tamai classification. We surgically repaired both proper digital arteries, excluded the vein, and then ligated 1 of the arteries. Using this technique, circulation was restored. Included in the outcome evaluation were 91 digits in the 87 patients (mean age, 35 years; range, 14-54) who returned for outcome assessments 12 months after surgery. RESULTS: Of 120 digits replanted, 115 digits survived, corresponding to an overall success rate of 96%. No patients received alternative means to alleviate venous congestion, such as leeches or other means of external bleeding. Nearly all of the 87 patients (91 digits) were satisfied with the results of the replantations. CONCLUSIONS: Our technique reconstructs circulation without vein anastomosis in zone I replantation. This alternative to venous congestion involves a simple surgical procedure and straightforward postoperative care. Follow-up assessments of a series of 120 replantations show that the majority of zone I replantations led to satisfactory function. We therefore propose this technique as an effective method for zone I replantation. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Zusammenfassung
120 zone I replantations (1997–2007) using bilateral digital artery repair plus selective artery ligation to establish circulation without vein anastomosis. 96% overall success rate; no patient required leech therapy or external bleeding for venous congestion control.
Warum dies für die Hirudotherapie relevant ist
The study evaluated a zone I fingertip replantation technique that repairs both proper digital arteries, excludes the vein, and ligates one artery to restore circulation without vein anastomosis. In 120 replantations, 115 digits survived, for a 96 percent success rate, and no patients received leeches or other external bleeding measures. This is relevant to ASH because it explicitly describes an alternative to medicinal leech therapy for venous congestion after distal replantation. The limitation is that the paper assesses one surgical technique rather than leech therapy itself, reports no direct comparison with leech use, and covers a specific distal-amputation population.
