title: Vascular microanastomosis through an endoscopic approach: feasibility study on two cadaver forearms.
abstract: The size of the incisions for free muscle flaps is often very large, and a source of deep adhesions and unaesthetic scars. But it is justified by performing the microsurgical step comfortably. In the hopes of shortening the size of incisions, the goal of this work was to study the feasibility of vascular microanastomoses through an endoscopic approach. The material consisted of two cadavers, a telemanipulator, and a vascular clamp. The antebrachial skin was detached then distended by gas insufflation. Four incisions, 1cm each, allowed the insertion of four trocarts connected to the telemanipulator. The artery was dissected (radial or ulnar) and the vascular clamp was introduced under the skin through one of the trocarts, and then installed on the dissected artery. The vascular anastomosis was performed with the use of a 10/0 nylon suture. The anastomosis lasted 2 hours under insufflation without any leak. The two arteries were identified then dissected without difficulty. The anastomosis was performed in good conditions. The assembling and disassembling of the clamp were time consuming. The main difficulties were caused by a long suture and a very fragile needle. Our results demonstrate the feasibility of vascular microanastomosis through an endoscopic approach. The next step is to perform the first clinical case for example on a latissimus dorsi free muscle flap.
