目的 探讨动 静脉 (A V)内瘘手术方式对内瘘血流量及使用寿命的影响。方法 6 2例尿毒症患者均施行A V内瘘手术 ,其中 4 9例行桡动脉和头静脉端 端吻合 ,13例行桡动脉和头静脉端 侧吻合 ,吻合口均采用间断缝合法。结果 内瘘成熟后 ,测内瘘吻合口内径均在 3 5～ 5 0mm ,瘘口平均分流量在 4 4 0～ 6 6 0ml min。 4 9例端 端吻合内瘘中有 3例仅使用 2年即失去功能 ,13例端 侧吻合内瘘使用至今无一例失去功能。结论 端 侧吻合内瘘使用寿命较长 ,且吻合口内径在 3 5～ 5 0mm较为合适 ,瘘口平均分流量可达 4 4 0～ 6 6 0ml min ,既能保证透析血流量 ,又能避免心衰等并发症
Objective To investigate the effect of arteriovenous (AV) fistula surgery on the fistula blood flow and service life. Methods Sixty-two patients with uremia were treated with AV fistula. Forty-nine patients received end-to-end anastomosis between the radial artery and the cephalic vein, and 13 patients received end-to-side anastomosis between the radial artery and the cephalic vein. Results After the fistula matured, the diameter of anastomotic fistula was between 35 and 50 mm, and the average fistula volume was between 40 and 66 minutes. In the 9 cases of end-to-end fistula, 3 cases lost their function in only 2 years. None of the 13 cases received end-to-side anastomotic fistula so far. Conclusions The end-to-end anastomosis fistula has a long service life, and the anastomotic internal diameter of 35 ~ 50mm is more appropriate. The average fistula fractional flow can reach 4400 ~ 6600ml min, which can not only ensure dialysis blood flow, but also avoid Heart failure and other complications
