“Background: There are case reports and small series in the literature relating to the use of medicinal leeches by plastic surgeons; however, larger series from individual units are rare. The aim of this article is to present a comprehensive 4-year case series of the use of medicinal leeches, discuss the

current evidence regarding indications, risks, and benefits and highlight the recent updates regarding leech speciation. Methods: Patients prescribed leeches in a 4-year period (July 2004–2008) Selleckchem AP24534 were collated from hospital pharmacy records (N = 35). The number of leeches used, demographic, clinical, and microbiological details were retrospectively analyzed. Results: Thirty-five patients were treated with leeches. The age range was 2 to 98 years (mean = 49.3). Leeches were most

commonly used for venous congestion in pedicled flaps and replantations. Blood transfusions were necessary in 12 cases (34%) [mean = 2.8 units, range 2–5 units]. Our infection rate was 20% (7/35) including five infections with Aeromonas spp. (14.2%). The proportion of patients becoming infected after Selleckchem AZD5363 leech therapy was significantly greater in the group of patients that did not receive prophylactic antibiotic treatment (Fisher’s Exact test P = 0.0005). In total, 14 cases (40%) were salvaged in entirety, in 7 cases 80% or more, in 2 cases 50 to 79%, and in 1 case less than 50% of the tissues were salvaged. In 11 cases (31%), the tissues were totally lost. Conclusion: Our study highlights both

the benefits and the risks to patients in selected clinical situations and also the potential risks. The routine use of antibiotic prophylaxis is supported. In view of the emerging evidence that Hirudo verbana are now used as standard leech therapy, and the primary pathogen is Aeromonas veronii, until a large prospective multicenter study is published, large series of patients treated with leeches should be reported. © 2011 Wiley-Liss, Inc.

“Background: Lymphaticovenular anastomosis (LVA) is becoming a choice of treatment for compression-refractory lymphedema. However, LVA requires highly sophisticated microsurgical technique called supermicrosurgery, and no training model for LVA has been developed. This study aimed to develop and evaluate feasibility of a new LVA model using rat thigh lymphatic vessels. Methods: Ten Sprague-Dawley rats were used for the study. After preoperative indocyanine green (ICG) lymphography, lymphatic vessels in posteromedial aspect of the thigh were dissected. In right limbs, the largest lymphatic vessel was anastomosed to the short saphenous vein or its branch, and the remaining lymphatic vessels were ligated (LVA group). In left limbs, all lymphatic vessels were ligated (control group). Anastomosis patency was evaluated intraoperatively and at postoperative 7 days.
