Autologous vein transplantation

After resection or revascularization, if the defect is too large, it should be more than 2 to 3 cm, or if it is estimated that excessive tension will occur after end-to-end anastomosis, vascular transplantation should be performed. Limb vascular transplantation usually takes autologous veins of the wounded, and its effect is better than that of artificial blood vessels. Ipsilateral saphenous vein grafts are often used to fill defects in the femoral, iliac, or axillary arteries. If the femoral and popliteal veins on the injured side are also injured, the great saphenous vein on the other side should be used. Transplanted veins may gradually dilate over time, so artificial blood vessels should be used when transplanting larger arteries (such as the upper femoral artery).
