title: [Application of crotch-shaped vein grafts in repairing defects of the vessels with a large diameter].
abstract: OBJECTIVE
  To investigate the results and application value of crotch-shaped vein grafts in repairing.
  
  
  METHODS
  From June 1998 to October 2003, 35 cases of vessel defects with defects of the vessels with a large diameter were repaired with crotch-shaped vein graft (29 males and 6 females, aged 18 to 45 years with an average of 25.7 years). The locations of defects were femoral artery in 25 cases, popliteal artery in 2 cases, femoral vein in 7 cases, and subclavian vein in 1 case. The interval between injury and operation was 1-8.5 hours (4.1 hours on average). The blood flows of trouble and healthy vascular were determined with Doppler detector and compared preoperatively and postoperatively.
  
  
  RESULTS
  All the anastomotic stomas were patent in 35 cases. Thirty-one cases were followed up 6 weeks to 24 months (9.5 months on average), the patent rate was 100%, no case occurred vasospasm or thromboembolism; 2 cases occurred stomal leak and became hematoma, 3 cases occurred muscular necrosis, and the 5 cases achieved primary healing after secondary operation. The Doppler results showed that there was statistically significant difference in the blood flow between postoperation and pre-operation (P < 0.01), but no statistically significant difference when compared the trouble vascular after operation with healthy vascular (P > 0.05).
  
  
  CONCLUSIONS
  The method of crotch-shaped vein grafts is safe and effective in repairing defects of vessels with a large diameter, which is easy to draw materials and handy to operate. It has a promising value in clinical application.
