[Reliability of venae comitant of facial artery as the donor vein in microvascular autologous submandibular gland transfer].

Abstract

To analyse the reliability of concomitant venae of facial artery as the donor vein in microvascular autologous submandibular gland transfer. One hundred and seventeen cases with severe keratoconjunctivitis sicca treated by microvascular transfer of autogenous submandibular gland transfer from August of 1999 to November of 2007 were reviewed. The cases were divided into three groups according to their different donor veins, with group A using facial veins, group B using concomitant venae of facial artery, and group C using a vein near the duct. Group A and B were compared in terms of venous thrombosis rate and failure rate related to venous thrombosis. Among 117 cases, there were 122 sides of submandibular gland transfers, with 93 in group A, 27 in group B, and 2 in group C. Postoperative venous thromboses rate was 15% in group A and 7% in group B, with significant difference (P < 0.01). The failure rate of transferred gland related to venous thrombosis was 8% in group A, and 7% in group B, with no significant difference (P > 0.05). Concomitant venae of facial artery can be used as reliable donor vein in microvascular autologous submandibular gland transfer.
