Management of donor and recipient veins in the vascularied autogeneous submandibular gland transfer / 中华显微外科杂志

ABSTRACT

Objective To discuss the management and selection of donor and recipient veins in the transfer of vascularied autogeneous submandibular gland (SMG).Methods The SMGs of 48 patients with severe keratoconjunctivitis were transfered to the temporal region by microsurgery from June,2002 to June,2013.The secreted saliva was used as the substitute of tear.Donor and accepting-site vessels,vessels crisis and managements,survival of grafts were retrospectively analysed.Results Transplantation succeeded in 45 patients and failed in 3.For donor veins,39 were facial veins,12 were venae comitantes of facial artery,1 was vein near the duct.For revipient veins,41 were superficial temporary veins,6 were deep temporary veins and 5 were veins in the upper neck.For revipient artery,except superficial temporary artery,deep temporary artery was also a good selection.After surgery,2/5 venous crisis cases were rescued by reanastomosising veins.TC99m examination suggested that the 49 TSMGs were survived,and the ducts were unobstructed.Follow up lasted for 6 months to 10 years,the symptoms of photophobia and anemophobia were alleviated,the symptoms of corneal xerosis disappeared.Good clinical efficacy was obtained after transplantion.Conclusion During SMGs transplantion,facial veins,venae comitantes of facial artery or vein near the duct can be used for donor vein.For recipient veins,except the superficial temporary veins as major,deep temporary veins or veins in the upper neck is also a secection.Correct selection and microsurgical management of donor and revipient veins are keys to successful SMGs transplantion.
