Leech Therapy Following Digital Replantation and Revascularization
Research article published in The Journal of hand surgery (2020)
Abstract
Venous congestion after digital replantation or revascularization threatens digit survival in the immediate postoperative period. External bloodletting, including leech therapy, provides a central role in salvage of the congested finger. Although there have been previous studies describing the initiation of leech therapy for digits experiencing venous insufficiency, few published articles and no consensus guidelines have discussed the weaning of leeches in the postoperative period. We review the current evidence behind leech therapy and offer a treatment algorithm based on available data and existing leech weaning protocols.

Summary
Venous congestion after digital replantation or revascularization threatens digit survival in the immediate postoperative period. External bloodletting, including leech therapy, provides a central role in salvage of the congested finger.
Why This Matters for Hirudotherapy
This review examines leech therapy as a means of managing venous congestion after digital replantation or revascularization, with particular attention to the postoperative weaning of leeches, an area the authors note has few published discussions and no consensus guidelines. It summarizes available evidence and proposes a treatment algorithm derived from existing data and leech weaning protocols. The work is directly relevant to hirudotherapy practice, as it addresses a well-established clinical indication for medicinal leech application and highlights a practical management gap — namely, how and when to discontinue therapy once venous outflow improves. As a review, it does not generate new primary clinical data; the abstract does not specify the number, design, or quality of the underlying studies supporting the algorithm, nor does it report outcome metrics validating the proposed protocol, so its recommendations should be understood as a synthesis of available evidence rather than tested guidance.
