FERNANDEZ DIAZ, Juan et al. Mechanical microvascular suture in head and neck reconstruction surgery. Rev Esp Cirug Oral y Maxilofac [online]. 2012, vol.34, n.4, pp.145-150. ISSN 2173-9161.  https://dx.doi.org/10.1016/j.maxilo.2012.05.015.

Objectives: To evaluate the efficacy and applicability of mechanical microvascular anastomosis performed in the artery and vein in the studied series. Material and method: A retrospective study of 25 patients who underwent microsurgical reconstruction of head and neck. Data were collected by: graft type, coupler size, recipient vessels, intraoperative patency test, anastomosis time, need for revision of anastomosis, and graft failure (venous thrombosis or arterial failure). Results: A series of 25 patients with 50 anastomosis. 25 venous, 22 arterial mechanical anastomisis and 3 converted to hand-sewn anastomosis. Recipient vessels: superior thyroid artery (70%) and venous branches of the thyro-linguo-facial common trunk (80%). The mean anastomosis time was 8min. Four patients required revision of the anastomosis, with a salvage rate of 25%. There were 3 failures, oneof which was a conversion to manual suturing. Conclusion: Microvascular mechanical anastomoisis is a technique with an efficiency at least equal to the hand-sewn artery and vein anastomosis, with a shorter anastomosis (60% time reduction) and arterial use with satisfactory results, taking into account certain restrictions.
