Abstract

Essential to the outcome of the replantation of digits is adequate arterial inflow and venous outflow. A nonoperative solution to the problem of venous insufficiency is leeching. The leech relieves venous congestion while attached, as the hirudin released by the leech continues to decongest the digit for 1-2 more hours. The emphasis of this article is a case study using leeches for venous congestion as an alternative to surgery.

Summary

Case study using medicinal leeches as a nonoperative alternative for venous congestion in digital replantation, with discussion of hirudin's continued decongestant effect for 1-2 hours after leech detachment.

Why This Matters for Hirudotherapy

This article presents a case study in which medicinal leeches were used to manage venous congestion following replantation of digits, serving as a nonoperative alternative to surgical intervention for venous insufficiency. The abstract describes the mechanism by which leeching relieves venous congestion — through bloodletting during attachment and continued decongestion for 1-2 hours afterward via hirudin released by the leech. For ASH's domain, this is directly relevant as a clinical application of hirudotherapy in reconstructive surgery, illustrating a therapeutic use of medicinal leeches. The study is limited to a single case report with no control group, no comparative outcomes, and no data on complications or infection risk, and the abstract provides minimal detail on patient demographics, specific digit(s) involved, number of leeches used, duration of therapy, or long-term outcomes.
