We report our initial experience with the PAS-Port proximal anastomosis system (Cardica Inc, Redwood City, CA) using full-skeletonized radial artery (RA) in patients requiring off-pump coronary artery bypass grafting.
The PAS-Port system (Cardica Inc) was used in 25 patients undergoing off-pump coronary artery bypass surgery. All patients received at least one RA graft using the PAS-Port system on the proximal anastomosis. The radial arteries were harvested in a fully skeletonized fashion before loading to the PAS-Port system.
Our attempt to use the PAS-Port system for proximal anastomosis of the RA was successful in 25 anastomoses. Postoperative angiography showed 24 grafts to be widely patent. During the mean postoperative follow-up of 9.2 +/- 3.1 months, there was no cardiac-related event in any patient. Mid-term patency collected from the first 8 patients was 87.5% (mean follow-up, 12.8 +/- 2.8 months).
The PAS-Port system does not require aortic clamping and enables the creation of uniform and widely patent anastomosis with use of RA grafts.
我们报告了在需要非体外循环冠状动脉搭桥术的患者中，使用全骨骼化桡动脉（RA）的PAS-Port近端吻合系统（加利福尼亚州红木城Cardica公司）的初步经验。
PAS-Port系统（Cardica公司）用于25例接受非体外循环冠状动脉搭桥手术的患者。所有患者在近端吻合时至少使用一根RA移植物进行PAS-Port系统操作。桡动脉在装入PAS-Port系统之前以全骨骼化方式获取。
我们使用PAS-Port系统进行RA近端吻合的尝试在25次吻合中成功。术后血管造影显示24根移植物广泛通畅。在平均9.2±3.1个月的术后随访期间，任何患者均未发生心脏相关事件。前8例患者的中期通畅率为87.5%（平均随访时间为12.8±2.8个月）。
PAS-Port系统不需要主动脉阻断，并且能够使用RA移植物创建均匀且广泛通畅的吻合。
