Endoscopic subfascial dissection of venous perforants in treatment of venous trophic ulcers of the legs

Endoscopic subfascial dissection was performed in patients with chronic venous insufficiency of CEAP class 4-6. 76 surgeries were performed in 68 patients. Mean age of the patients was 56 years. The causes of chronic venous insufficiency were varicose (37) and postthrombotic diseases. Trophic ulcers were in 46 patients. Thirty patients underwent earlier various phlebectomies, including Linton's surgery (6 patients). In 33 patients endoscopic subfascial dissection of venous perforants was combined with various phlebectomy, in 37 patients -- with excision of ulcer with following autodermoplasty few days after surgery. Endoscopic subfascial dissection was carried out with special surgical R.Wolf endoscope with 6 mm instrumental canal, and also standard laparoscopic optical devices "Olympus". Complications during surgery were seen in 2 patients: bleeding in subfascial space (1.3%) and perforation of tissues in ulcer zone (1.3%). In postoperative period long (up to 14 days) lymphorrhea and suppuration of surgical wound were in 2 (2.6%) patients. It is concluded that endoscopic approach is optimal for elimination of pathological reflux through venous perforants in complicated forms of chronic venous insufficiency of the lower extremities, including trophic ulcers resistant to treatment.
