Objective: Functional vein end to arterial side (ETS) anastomosis uses vein side to arterial side (STS) anastomosis with distal vein ligation, which can achieve similar effects as those of ETS after STS anastomosis. The purpose of the study was to provide a meta-analysis to compare the clinical outcomes between traditional and functional ETS anastomosis in radiocephalic fistula for dialysis access.
Methods: Databases including PubMed, EMbase, the Cochrane Library, CNKI, Wanfang database were searched from the inception to February 6, 2020. Eligible studies comparing traditional and functional ETS anastomosis in radiocephalic fistula were included. Data were analyzed using Review Manager Version 5.3.
Results: Seven studies were included in the meta-analysis. Five randomized controlled trials and two cohort studies involving 841 patients were identified. Compared with traditional ETS anastomosis, functional ETS anastomosis had shorter anastomosis time (MD - 9.54, 95% CI - 17.96 to - 1.12, P = 0.03), higher surgical success rate (OR 3.80, 95% CI 1.76-8.22, P < 0.01), fewer complications(OR 0.18, 95% CI 0.08-0.39, P < 0.01), higher patency rate after 3 months (OR 4.91, 95% CI 1.19-20.33, P = 0.03), higher patency rate after 6 months (OR 1.90, 95%CI 1.09-3.31, P = 0.02), higher patency rate after 12 months (OR 1.70, 95% CI 1.09-2.66, P = 0.02). There was no difference after the two arteriovenous (AVF) anastomosisl methods concerning AVF maturation time (SMD - 0.48, 95% CI - 1.30-0.34, P = 0.25) and patency rate after 1 month (OR 1.77, 95% CI 0.65-4.80, P = 0.26).
Conclusion: Functional ETS anastomosis had advantages of easy operation, high surgical success rate, few complications, high patency rate of 3 months and long-term, but did not have obvious advantage in the early stages concerning AVF maturation time and 1-month patency rate.

Autogenous arteriovenous fistula (AVF) is the vascular access of choice for chronic kidney disease to patients requiring hemodialysis. However, there still needs to be more consensus on whether the best surgical approach is an end-of-vein to side-of-artery (ETS) or a side-of-vein to side-of-artery (STS) anastomosis. This study aims to compare venous maturation rates, mid-term patency and post-operative steal syndrome rates between ETS and STS techniques for arteriovenous fistulas.

Background: Complex lower extremity defects are difficult to cover and often require multiple free tissue transfers. Chimeric anterolateral thigh free flaps (ALTF) and peroneal artery perforator free flaps (PAPF) have been designed specifically as an alternative for reconstruction with arterial end-to-side (ETS) anastomosis. We aimed to assess our institutional experience with this technique and to define its role in complex lower extremity reconstruction.

End-to-side (ETS) microsurgical anastomosis is a powerful technique in microsurgery. It can overcome vessel's diameter discrepancy and preserve the distal blood flow. Optimal angle of the ETS anastomosis has been debated and studied, and is currently limited to animal models.

Introduction: The operating room is no longer the ideal place for early surgica training of cardiothoracic surgery residents, forcing the search for simulation-based learning options. The study's aim was the construction and surgicaltraining of coronary anastomosis in a portable, low-cost, homemade simulator.

Background: Free flap reconstruction of the lower extremity is technically challenging and may suffer from higher complication rates than other anatomical sites. One important vascular consideration in the reconstructive process is the microsurgical anastomotic technique, namely whether an end-to-end (ETE) or end-to side (ETS) technique is used. The ETS technique is often preferred by lower limb microsurgeons, who describe its benefits of improved distal perfusion.
