Experimental arteriovenous fistulas of end-to-end (ETE) and end-to-side (ETS) type were created with microsurgical technique in rabbits between the carotid artery and the facial vein. Blood pressure and blood flow through the fistulas were registered during the operation and the flow capacity (flow/BP) was calculated. Evaluation was made at 2 hours, 1 day, 1 month and 3 months. Immediately after completion of the anastomosis there was no statistically significant difference in blood flow capacity between the ETE and the ETS group. At 1 month the flow capacity had increased significantly in the ETS, but not in the ETE group. At 3 months 3/5 of the ETS anastomoses remained patent, but all the ETE types were occluded. Histologic findings included severe intimal thickening at the anastomotic level and on the venous side of the anastomosis at 1 and 3 months. The study indicated that late blood flow and patency may be greater in ETS than in ETE arteriovenous fistulas.
采用显微外科技术在兔的颈动脉和面静脉之间建立端对端（ETE）和端对侧（ETS）型实验性动静脉瘘。术中记录通过瘘管的血压和血流量，并计算流量能力（流量/血压）。在术后2小时、1天、1个月和3个月进行评估。吻合完成后立即测量，ETE组和ETS组之间的血流能力无统计学显著差异。1个月时，ETS组的流量能力显著增加，而ETE组未增加。3个月时，5个ETS吻合口中有3个保持通畅，但所有ETE型均闭塞。组织学检查结果包括在1个月和3个月时吻合口水平及吻合口静脉侧出现严重内膜增厚。该研究表明，ETS型动静脉瘘的晚期血流量和通畅率可能高于ETE型。
