尿毒症患者由于多种原因,难以用自身血管建立理想的内瘘,甚至不得不终止透析。最近我们应用聚氟四乙烯(PTFE)人造血管成功地为三名晚期尿毒症患者建立了内瘘,并进行了穿刺透析。* 病例选择病例1 女性,63岁,因慢性肾炎致肾衰。行腹透一年后因反复腹膜炎而中止。其间曾先后行左前臂、右前臂桡动脉与正中静脉吻合术,均因静脉血管较细(直径<2mm),仅维持3月即闭塞。病例2 男性,74岁,高血压致肾衰。腹透4年后因腹壁疝、腹股沟疝并发肠梗阻而中止,靠临时插管来维持血透。期间也曾行左、右前臂内瘘成形术,均因动脉硬化桡动脉管腔狭
Patients with uremia due to many reasons, it is difficult to use their own blood vessels to establish the ideal fistula, and even had to terminate dialysis. Recently, we have successfully established fistulas in three patients with advanced uremia using perfusion of PTFE and performed dialysis. * Case selection 1 female, 63 years old, due to chronic nephritis caused by renal failure. Peritoneal dialysis one year after termination due to repeated peritonitis. During which have been left forearm, right forearm radial artery and median vein anastomosis, both due to thinner venous blood vessels (diameter <2mm), only to maintain the occlusion in March. Case 2 Male, 74 years old, high blood pressure caused by renal failure. Abdominal dialysis 4 years later due to abdominal hernia, inguinal hernia complicated by intestinal obstruction and stop by temporary intubation to maintain hemodialysis. Also during the left and right forearm fistula angioplasty, both due to atherosclerosis of the radial artery lumen narrow
