microvascular suturing technique

Many training models such as suturing of surgical gloves, silastic tubes, and animal models can be used for learning microvascular technique [4,7] . MICROVASCULAR ANASTOMOSIS TECHNIQUE Ottie van Zyl, Johan Fagan This chapter describes the surgical techni-que of microvascular anastomosis, and the management of patients undergoing vascu- larrised free tissue transfer reconstruction of the head and neck. When the posterior wall technique [Br J Plast Surg 34 (1981) 47, Plast Reconstr Surg 69 (1982) 139, Microsurgery 8 (1987) 22, J Reconstr Microsurg 15 (1999) 321] is used, the loose end of the suture may be stuck to the backside of the vessel and may be hard to grab. gical suture technique for microvascular anastomosis, and continues to present the array of non-suture methods currently proposed as alternatives to standard suturing. The loops are then serially cut and tied, resulting in efficiently placed … Clinically, this method may be advantageous in cases where the anastomosis is being performed in a deep wound in which there is no room to turn over the microclamp. The practice of knots untying technique using a 10-0 nylon suture and gauze to cope with technical difficulties of microvascular anastomosis In our experience of training young neurosurgeons, practice of KUT contributes to shortening the duration of blood-flow blockage and helps mastering the technique of successful microvascular anastomosis.

Training in microvascular surgery using a chicken wing artery. A simple and novel technique for training in microvascular suturing in a rat model. An additional histological study was performed to compare their immediate traumatic effects on vessel wall. https://doi.org/10.1016/j.bjps.2004.06.009. In group 1, microanastomosis was done with conventional suturing whereas microvascular couplers were used in group 2. “A New Technique of Microvascular Suturing: The Chopstick Rest Technique.” BRITISH JOURNAL OF PLASTIC SURGERY 57.6 … gical suture technique for microvascular anastomosis, and continues to present the array of non-suture methods currently proposed as alternatives to standard suturing. - total thrombosis rate was 8%, but no significant patency difference was noted between the CST and the interrupted suture technique in any vessel category. Search for … Presented at the 6th International Course on Perforator Flaps, Taipei, Taiwan, October 25–27, 2002. 2 This technique, however, is often considered to be … End-to-side anastomoses were the most common procedure for extracranial-to-intracranial bypass. In the process of retrieving the suture, the surrounding tissues can be picked up together with the suture. It demands the full attention of the surgeon throughout the procedure. Anthony V. Seaber. Vessels and nerves could be exposed and dissected up to a diameter of 1 mm and allowed for microvascular suturing even after weeks like fresh specimens. Compared with microvascular clamps, silk slipknot is a cheap, easily available, less space-occupying technique while performing microvascular anastomoses training. The authors used the double-suture technique in seven cases (nine anastomoses). In case of the pressure resistance test the groups were: the simple interrupted, the continuous suture and the modified Lauritzen's sleeve-technique. In order to avoid those problems, a new way of tying a microsuture was developed. Microvascular suturing has now become routine, being performed in countless centres for microvascular surgery throughout the entire world with individual modifications to certain details. The authors innovated heel suturing on the donor vessel prior to arteriotomy (HSDA) technique from the previously … Biomechanical comparison of microvascular anastomoses prepared by various suturing techniques. Jaeger MR, Ely PB, Pires JA, Ferreira LM. This site needs JavaScript to work properly. A simple and novel technique for training in microvascular suturing in a rat model. Department of Orthopaedic Surgery, Affiliated First Hospital, Sun Yat‐Sen University of Medical Sciences, Guangzhou, People's Republic of China . Suturing of microvascular anastomosis is still a time-consuming procedure, despite the fact that different techniques and devices were designed to reduce the operation time and increase the patency rate. The time taken for anastomosis (time taken for suturing and applying couplers) and flap ischemic time (from the time of flap division from the donor site till the flap is reperfused … Anastomoses should be water-tight with the least number of sutures. Biomechanical comparison of microvascular anastomoses prepared by various suturing techniques. Methods: In this review, the authors take a brief look at the developments of this technology through the years, with a focus on the more recent … Other endpoints, including ischemic time, patency rate, and only suturing!
