title: [Management of blood vessels in the vascularized autogenous submandibular gland transfer for severe keratoconjunctivitis sicca].
abstract: OBJECTIVE
  To summarize the management of blood vessels in the transfer of vascularized autogenous submandibular gland.
  
  
  METHODS
  Sixty-eight cases of vascularized transfer of autogenous submandibular gland for severe keratoconjunctivitis sicca performed from August 1999 to April 2004 were reviewed. Data collected for each patient included general items, donor and recipient vessels, vessel crisis, salvage of the vessel thrombosis, and survival of transferred glands.
  
  
  RESULTS
  Among the 68 cases, all the donor and recipient arteries were facial artery and superficial temporal artery respectively. For donor veins, 55 were facial veins, 1 was vein near the duct, and 12 were venae comitantes of facial artery. For recipient veins, 62 were superficial temporary veins and five were veins in the upper neck, one was deep temporary vein. Vessel thromboses occurred in 10 cases, 9 were venous and 1 were arterial. The salvage rate was 10.0%, with the overall survival rate of 86.8% of transferred gland.
  
  
  CONCLUSIONS
  Variation in venous outflow is common in microvascular transfer of submandibular gland, and anastomosis between venae comitante of facial artery and superficial temporal vein is most dependable. Vessel anastomosis under microscope may reduce the vessel thrombosis rate after operation.
