This article reported 4 cases of reconstrution of the superficial palmar arch from transplantation of the vein arch of the dorsalis pedis by microsurgery. This technique was best reserved for those having significant damage of the palmar vesels. There were no arterial failures in these patients. The operative indications and some problems about the arterialized vein arch were discussed.
OBJECTIVE To investigate the clinical application of artificial blood vessel graft for arteriovenous fistulization. METHODS From October 1995 to August 1998, 23 cases with renal failure received PTEF artificial vessels grafting for arteriovenous fistulization in the forearm. The PTFE artificial vessel was 6 mm in diameter, and 40 cm in length. Artificial vessel "U"-shaped loop was formed from elbow incision to wrist incision, and perfused by 20 ml heparin saline. The two ends of artificial vessel were end-to-side anastomosed with superficial cubital vein and cubital artery respectively. RESULTS All of arteriovenous fistulas were successfully formed, and could be performed hemodialysis periodically. The artificial vessels could be punctured repeatedly, and had sufficient volume of blood flow. It had no rejection, no formation of false aneurysm, and no ischemia in arm or exacerbated reflux to heart. CONCLUSION The artificial vessel grafting for arteriovenous fistulization is a safe and convenient technique in clinical practice, especially when there is no autogenous vessels for arteriovenous fistula.
