摘要
目的比较氢氯吡格雷和双嘧达莫对预防自体大隐静脉移植内瘘失功的临床疗效及安全性。方法前瞻性纳入2009年1月至2012年05月期间行自体大隐静脉移植内瘘的患者,术后随机分为氢氯吡格雷治疗组(A组),双嘧达莫治疗组(B组),于治疗后3个月及6个月观察移植静脉内瘘的通畅率、狭窄率、动脉吻合口内径、静脉吻合口内径、动脉段内径(距动脉吻合口3cm)及静脉段内径(距静脉吻合口3cm)等指标,以及药物并发症和不良反应。使用SPSS17.0软件进行统计分析。结果共纳入病例30例,其中A组16例,B组14例。A组治疗3个月、6个月的通畅率均较B组的高,狭窄率均较B组的低。其中A组治疗6个月的通畅率(81.25%)较B组(35.71%)的差异有显著性(=6.451,P=0.024),A组治疗3个月动脉吻合口、静脉吻合口内径较B组略大,但差异无显著性(P>0.05),相应时段移植静脉动脉段内径(距动脉吻合口3cm)及静脉段内径(距静脉吻合口3cm)差异无显著性;A组治疗6个月动脉吻合口、静脉吻合口内径较B组大,差异有显著性(t值分别为2.142,2.132,P值分别为0.041、0.042),相应时段移植静脉动脉段内径(距动脉吻合口3cm)及静脉段内径(距静脉吻合口3cm)略大,但差异无显著性。两组均未出现严重不良反应。结论氢氯吡格雷预防自体大隐静脉移植内瘘狭窄及血栓形成的效果优于双嘧达莫,无明显不良反应,具有广阔的应用前景。
Objective To compare the efficacy and safety of clopidogre and dipyridamole for the prevention of autologous great saphenous venous transposition fistula dysfunction. Methods We prospec- tively recruited patients who received the operation of autologous great saphenous venous transposition fistula. After the surgery, patients were randomly assigned into either clopidogre group （group A） or dipy- ridamole group （group B）. At the 3rd and 6th months after the enrollment, fistula patency, stenosis rate, arterial anastomotic diameter, venous anastomotic diameter, diameters of the arterial/venous graft segments （3cm from arterial/venous anastomotic sites）, complications, and adverse events were recorded. Data were analyzed by using SPSS 17.0 software. Results We observed 30 patients, of which 16 were in group A, and 14 were in group B. At the time points of 3rd and 6th months, group Ahad a higher fistula patency rate and a lower stenosis rate than group B. At the 6th month, fistula patency was statistically significant between the two groups （Z~=6. 451, /）=0.024）. Arterial and venous anastomotic diameters were slight wider in group A than in group B but without statistical significance （P 〉 0.05） at the 3rd month, and were significant larger in group Athan in group B （t=-2. 142 and 2. 132, P=-0.041 and 0.042, respectively） at the 6th month. Diameters of the arterial/venous graft segments were similar between the two groups at 3rd and 6th months. No severe adverse effects were reported in either of the two groups. Conclusions Clopidogre is superior to dipyridamole in the prevention of thrombosis and stenosis in autologous great saphenous venous transposi- tion fistula without notable adverse effects. As an anti-platelet therapy for fistula preservation, clopidogre shows better effects for clinical use.
