The treatment modality of choice for venous insufficiency after free tissue transfer or replantation remains surgical repair. When this is not technically possible, the use of medical leeches is a useful adjunct to treatment. This paper reviews the history of the use of leeches in medicine, the anatomy and physiology of Hirudo medicinalis, the techniques of leech therapy, and the complications and contraindications. © 1993 Wiley‐Liss Inc. 
Medicinal leeches for the treatment of venous congestion and hematoma after plastic reconstructive surgery
TLDR
The use of medicinal leeches became rather popular again in recent years, e.
A Comprehensive Review of Medicinal Leeches in Plastic and Reconstructive Surgery
TLDR
The purpose of this article is to provide a platform for understanding the recent literature as it relates to reconstruction to improve understanding of indications and necessary considerations in using hirudotherapy.
Successful treatment of venous congestion in free skin flaps using medical leeches
TLDR
The results from this small number of patients with free skin tissue transfers are encouraging, suggesting that in the presence of venous congestion, the use of medicinal leeches is a desirable modality of treatment.

The history of this ancient therapy is discussed, the leech and its present indications, complications, contraindications, and techniques are described.
Cutaneous complications of improper leech application.
TLDR
Infection is considered the most common complication of hirudotherapy, even though bacteriological examination of leech applied by the patient showed neither bacterial nor parasitic infection.

TLDR
A synthesis of current best evidence guides clinicians during the process of consenting patients and using leeches in their practice in the absence of robust randomized controlled trials on which the evidence may be based.
Leech therapy in the management of acute venous congestion of an infant's lower limb.
TLDR

Hospital-associated infection from leeches.

Aeromonas hydrophila Infections Following Use of Medicinal Leeches in Replantation and Flap Surgery
TLDR
It is recommended that leech applications be restricted to tissue with arterial perfusion to minimize contamination of necrotic tissue and that patients treated with leeches receive antibiotics effective against Aeromonas hydrophila before leech application.
