Leech therapy in cutaneous surgery and disease
Review and case series published in J Drugs Dermatol (2010)
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 case series and review of the literature describes 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 the leech's mechanical blood-extraction ability, can contribute to patient health with minimal risks. The findings are directly relevant to ASH and hirudotherapy practice, as the authors conclude leeches should be considered as therapies for disorders of coagulation and venous congestion — core applications of medicinal leech use. However, as a case series and narrative review rather than a controlled trial, the study does not provide high-level efficacy evidence, and the authors themselves caution that implementation must account for potential adverse effects including Aeromonas infection and hematocrit decreases that may require blood transfusion.
