The main goals in the development of an anastomotic device are to reduce the invasiveness of the procedure and to improve graft patency. We analyze our preliminary clinical experience with the Ventrica magnetic vascular positioner (MVP) series 6000 system.
Eighteen distal anastomoses were performed in 11 patients using the MVP.
The target artery for MVP was left anterior descending in 9 patients, a marginal branch in 4, the first diagonal branch in 3, and the right coronary artery in 2. Graft material was the left internal thoracic artery in 9 patients, saphenous vein in 6, the right internal thoracic artery in 2, and the radial artery in 1 case. Fifteen anastomoses were performed in an end-to-side and 3 in a side-to-side fashion. Predischarge angiography was performed in 10 of 11 patients. There was a patent MVP anastomosis in all patients.
Distal anastomoses using the MVP were performed successfully in all patients. The procedure is simple. Short-term patency is excellent. Further randomized trials are necessary to determine long-term safety and patency.
吻合装置研发的主要目标是降低手术的侵入性并提高移植物通畅率。我们分析了我们使用Ventrica磁性血管定位器（MVP）6000系列系统的初步临床经验。
11例患者使用MVP进行了18次远端吻合。
MVP的目标动脉在9例患者中为左前降支，4例为边缘支，3例为第一对角支，2例为右冠状动脉。9例患者的移植物材料为左胸廓内动脉，6例为大隐静脉，2例为右胸廓内动脉，1例为桡动脉。15次吻合采用端侧吻合方式，3次采用侧侧吻合方式。11例患者中有10例在出院前进行了血管造影。所有患者的MVP吻合均通畅。
所有患者使用MVP成功进行了远端吻合。该手术操作简单。短期通畅率极佳。需要进一步的随机试验来确定长期安全性和通畅率。
