目的：探讨前臂类似聚四氟乙烯(PTFE)透析移植物的狭窄分布及血管成形术效果。材料与方法：回顾215例前臂PTFE环状透析移植物术后瘘的诊断影像资料，其中90例前臂PTFE环状透析移植物未做翻修。对于每个可测量的狭窄，回顾血管成形术的位置、形态和结果。结果：在最初诊断的瘘管图上，发现93处狭窄，其中47%位于静脉吻合口，11%位于吻合口1 cm以内。生命表分析显示，第1次血管成形术的6个月通畅率为63%，1年通畅率为41%，第2次血管成形术的6个月通畅率为50%，1年通畅率为25%。结论：连续静脉血管成形术有助于延长移植物的寿命，但随着后续干预的进行，通畅率会降低。
PURPOSE: To determine the distribution of stenoses and results of angioplasty in patients with similar forearm dialysis grafts made of polytetrafluoroethylene (PTFE).MATERIALS AND METHODS: Diagnostic radiographs of the fistula obtained in 215 patients were reviewed; 90 patients had similar, unrevised forearm PTFE loop dialysis grafts. The location, morphology, and results of angioplasty were reviewed for each measurable stenosis. Surgical, radiologic, and dialysis records were reviewed to document the subsequent patency rate of each patient's dialysis access.RESULTS: On the initial diagnostic fistulogram, 93 stenoses were identified, The anatomic distribution included 47% at the venous anastomosis and 11% within 1 cm of the anastomosis. Life table analysis revealed a 6-month patency rate of 63% and a 1-year patency rate of 41% for the first angioplasty in a given graft, and a 6-month patency rate of 50% and a 1-year patency rate of 25% for the second angioplasty.CONCLUSION: Performance of serial venous angioplasty procedures may help prolong the life of a graft, but the patency rates diminish with subsequent interventions.
