Abstract

Digit replantation has undergone significant advancements since the 1960s. Despite progress, distal digit replantation remains one of the most challenging microsurgical procedures due to technical and clinical complexities. This review examines current challenges, strategic solutions in distal digit replantation, grounded in clinical experience and literature review. Key obstacles include managing minute vessel structures, venous congestion, and the critical condition of no available vessels for revascularization. Advances in surgical techniques, including preosteosynthesis vein grafting, intravascular stent, solitary central pulp artery bifurcation division, subdermal pocketing method, and postoperative management, have enhanced outcomes.

Summary

Review of challenges and strategies for distal digit replantation outcome improvement.

Why This Matters for Hirudotherapy

This review examines challenges and strategic solutions in distal digit replantation, identifying venous congestion and scenarios with no available vessels for revascularization as key clinical obstacles. The relevance to hirudotherapy is strong and well-established: medicinal leech therapy is a recognized adjunct for managing venous congestion following digit replantation, where leech-mediated bloodletting and hirudin-driven anticoagulation help sustain tissue viability when venous outflow is inadequate. The abstract's discussion of postoperative management further highlights the clinical space where leech therapy is typically deployed. An honest caveat: this is a narrative review centered on surgical techniques rather than a study evaluating leech therapy itself, so it provides no outcome data specific to hirudotherapy.
