Objective To repair defects at both ends of the blood vessels with a considerable disparity in the diameter of the both sides or with a large diameter in extremities by phleboplasty of branched and double autogenous veins. Methods Three kinds of phleboplasties——funnel-shaped, raincape-shaped and transposed Y-shaped were designed. Experiments in fresh blood vessels in vitro were completed successfully. These methods were used clinically to repair injured external iliac veins, femoral arteries and veins, and popliteal arteries and veins, to replant severed fingers and to transplant toenail flaps on thumbs by harvesting autogenous great saphenous veins,small saphenous veins and forearm veins in 36 cases, including 35 cases in emergency operation and 1 case in selective operation. The length of grafted blood vessels ranged from 1.0 cm to 15.0 cm. Results The phleboplasties of funnel-shaped could enlarge the diameter by 1.0-1.25 times in anastomotic stomas. The phleboplasty of raincape-shaped could enlarge the diameter large enough to meet the demands for various blood vessels in extremities. The phleboplasty of transposed Y-shaped could provide large vein transplants. In 36 grafted veins, 35 were in patency. The blood supply in extremities was normal.Conclusion The funnel-shaped and raincape-shaped phleboplasties of branched veins can enlarge the anastomotic stomas of grafted veins. The transposed Y-shaped phleboplasty of double femoral veins is an ideal way to repair injured primary blood vessels with a considerable disparity in the diameter of the both sides or with a large diameter in extremities.
