Abstract
Objective Evaluate data of 1270 cases with free flap transplant,to find the problems in the process of operation,and then to analyse its causes and how to prevent and solve it,as well as providing reference for clinical colleagues. Methods To study 1270 cases of free flaps,musculocutaneous flap and perforator flap who was treated in our hospital from October 2000 to October 2010 retrospectively. A total of 722 cases of the group were followed-up 6 months to 5 years. To detective and search the problems and imperfection from designing,harvesting,tranfer,to the management and function of donor site after free flap transplantion.And also to analysis the couse of problems and operation failure,discuss the conclude of and to provide advisable measure. Results Total 1270 free flaps were transplanted successfully except 64 can-celled or failured for some reason, the success rate was 95.0％, the postopertive necrosis rate was 3.8％.Seventy-six cases were encountered vascular complications venous crisis in 42,arterial crisis in 38.Fifty-five cases were saved successfully without surgery,and 15 cases survived completely by vessel explorative operation. Five cases were partial necrosis and 7 cases necrosis. The rate of postoperative infection of emergency cases and chronic one were 4.7％ (682 cases)and 8.8％(588 cases) which show the infective incidence of latter was higher than former. In addition, there were many other problems were found such as distal flaps necrosis,contracture,deformation,impairment function of doner site,etc. Conclusion Preventing and management timely to vessle crisis is the key to flap suvive. The principle of dissecting flap should be followed strictly,and control the indications of modified processing during flap harvest,keep the proper flap tension were technical requirements in flap transplantion. Right way of donor site closed and management of insufficient timely were equally important to prevent and solve to complications and dysfunction.
