Vein allografts were obtained from varicose vein patients in whom stripping and ligation was indicated. Proximal 30 cms of the long saphenous vein was removed and stored at -30 degrees C. A-V fistulas were constructed in the upper arm between brachial artery and the brachial or cephalic vein in dialysis patients. All these allograft vein recipients had major blood groups identical to the donors. Clinical experience over a two year period revealed a 100% long term patency. Complications including early graft thrombosis, superficial wound infection, hematoma formation and local edema were few and easily managed. Allograft rejection was not a problem in this series of patients. The large diameter grafts in upper arm position function well. They are convenient for the patient and preferred by dialysis personnel as a direct site for venepuncture. An initial experience suggests that preserved vein allografts may become the preferred material for arteriovenous fistulas.
静脉同种异体移植物取自需要进行剥脱和结扎手术的静脉曲张患者。切除大隐静脉近端30厘米并储存在-30摄氏度。在透析患者的上臂，于肱动脉与肱静脉或头静脉之间构建动静脉内瘘。所有这些接受同种异体静脉移植的患者的主要血型与供体相同。两年的临床经验显示长期通畅率为100%。包括早期移植物血栓形成、浅表伤口感染、血肿形成和局部水肿在内的并发症很少且易于处理。在这组患者中，同种异体移植排斥不是问题。上臂位置的大口径移植物功能良好。它们对患者方便，并且被透析人员作为静脉穿刺的直接部位所青睐。初步经验表明，保存的静脉同种异体移植物可能会成为动静脉内瘘的首选材料。
