Abstract

BACKGROUND: Over the ages, the use of leeches in medicine has evolved from haphazard bloodletting to a well-understood physiologic process with defined, rational applications. OBJECTIVE: The authors describe the current role of leech therapy in cutaneous surgery and medicine. METHODS: Case series and review of the literature. RESULTS: Leech saliva contains anticoagulative, anti-aggregative and vasodilatory components. Combined with the annelid's mechanical ability to extract blood, leeches can contribute to patients' health with minimal risks. CONCLUSION: Leeches should be considered as novel therapies for disorders of coagulation and venous congestion. Implementation of leech treatment should be tempered with the potential adverse effects, including Aeromonas infection and a drop in hematocrit that might require a blood transfusion.

Summary

Case series and literature review of leech therapy in cutaneous surgery and dermatologic disease. Documents anticoagulative, anti-aggregative, and vasodilatory components of leech saliva alongside Aeromonas/transfusion risks.

Why This Matters for Hirudotherapy

This article presents case reports and a literature review describing the current role of leech therapy in cutaneous surgery and medicine, highlighting that leech saliva contains anticoagulative, anti-aggregative, and vasodilatory components that, combined with mechanical blood extraction, can benefit patients with minimal risks. The authors conclude that leeches should be considered for disorders of coagulation and venous congestion, while cautioning about potential Aeromonas infection and hematocrit drops requiring transfusion. This is directly relevant to ASH's domain as it addresses clinical hirudotherapy applications and safety. However, as a case series and literature review, it lacks controlled trial data, and the abstract does not specify the number of cases or provide quantitative outcomes.
