Summary:. In dialysis patients, peripheral venous hypertension–induced hand ulcers are rare. We report a case in which a severe hand ulcer was treated with skin grafting after shunt ligation. The patient was a 60-year-old woman who been undergoing dialysis for 13 years. Twelve years ago, a shunt was created in her right wrist via a side-to-side anastomosis. Swelling and congestion occurred in the right hand, and skin ulcers developed on the dorsal proximal portions of the index, middle, ring, and little fingers. No central vein obstruction was apparent. The right wrist shunt was explored, and the distal vein was ligated. A new shunt was created at the right elbow, but the proximal end of the vein that was used for the wrist shunt had to be used, resulting in complete cephalic vein occlusion from the wrist to the elbow. The swelling extended to the entire forearm. Four weeks after the wrist and elbow shunts were ligated, conservative treatment had resulted in granulation tissue formation in the ulcers. Debridement and full-thickness skin grafting from the abdomen were performed. Overall, skin graft survival was 75%. In conclusion, in this patient, side-to-end anastomosis of the proximal vein might be appropriate for shunt creation. When venous hypertension is suspected, ensuring an appropriate alternative shunt, promptly detecting the cause of the problem, and appropriate treatment are important. Venous hypertension must be completely resolved before surgery for ulcers.
