Abstract

Digits that were formerly assessed as nonreplantable may now be replanted with the help of the leech Hirudo medicinalis. The early experience with a series of patients who had relative contraindications for replantation is reported. In each case, venous repair was either marginal or technically impossible. Postoperative venous congestion developed following replantation and was treated with the application of medicinal leeches. Patient acceptance was high, and no infections developed. No patient required transfusion. The authors conclude that the use of medicinal leeches shows promise as a safe and effective method of providing temporary venous drainage in replanted digits.

Summary

Digits that were formerly assessed as nonreplantable may now be replanted with the help of the leech Hirudo medicinalis. The early experience with a series of patients who had relative contraindications for replantation is reported.

Why This Matters for Hirudotherapy

This article reports early clinical experience using the medicinal leech Hirudo medicinalis to manage postoperative venous congestion in replanted digits where venous repair was marginal or technically impossible. The authors note high patient acceptance, no postoperative infections, and no transfusion requirements, concluding that leech therapy shows promise as a temporary venous drainage strategy in this setting. This work is directly relevant to hirudotherapy and ASH's domain, documenting a core clinical application of leech-mediated bloodletting to salvage compromised surgical tissue. However, the abstract provides no patient numbers, quantitative success or survival rates, duration of therapy, or long-term functional outcomes, representing only preliminary clinical observation without controlled or comparative data.
