Abstract

Medical grade leeches have recently been used in the management of acute problems relative to venous congestion in patients with traumatic injuries and surgical problems. Specific cases, especially in the realm of reconstructive microsurgery, have demonstrated the effectiveness and application of leech therapy. Specific contraindications include arterial insufficiency from either anatomic or mechanical obstruction. We present five illustrative cases of successful therapeutic intervention.

Summary

Five illustrative cases of successful leech therapy in venous congestion management; arterial insufficiency identified as contraindication.

Why This Matters for Hirudotherapy

This case-report article presents five illustrative cases of successful therapeutic application of medical-grade leeches for managing acute venous congestion in patients with traumatic injuries and surgical problems, particularly in the realm of reconstructive microsurgery. This is directly relevant to ASH's domain, as it documents modern clinical hirudotherapy in practice and identifies specific contraindications including arterial insufficiency from anatomic or mechanical obstruction. As indicated by its publication type (Case Reports), the evidence consists of selected successful cases without a control group or systematic outcome reporting, which limits the generalizability of the reported effectiveness.
