64层螺旋 CT 评价冠状动脉搭桥术后桥血管通畅性的变化
Evaluation of grafts patency changes after coronary artery bypass grafting with 64 multi-detector computed tomography
摘要
Abstract
Objective To assess the left internal mammary artery (LIMA)and saphenous vein (SV)grafts patency changes with time after coronary artery bypass grafting ( CABG) by using 64 multi-detector computed tomography(MDCT).Methods From March 2012 to March 2015,146 patients underwent CABG operation and postoperative serial 64-MDCT follow-up.The early postoperative (mean interval 5.2 months)64-MDCT findings of these patients were compared with the late MDCT findings (average 21.6 months).A total of 143 LIMA and 184 SV grafts with 384 distal anastomoses were assessed .Results In the early MDCT,the patencies were 93.0% and 92.9% for LIMA and SV grafts,respectively.In the late MDCT,the corresponding values were 90.0% and 87.5%. Compared with the early MDCT,deterioration in graft patency occurred in 5 LIMA grafts(4 anastomosed to LAD and 1 anastomosed to RCA) in 5 patients and 10 SV grafts(4 anastomosed to D,3 anastomosed to RCA territory,1 anastomosed to OM,2 sequentially anastomosed to OM and RCA territory ) in 8 patients.There was no patency deterioration difference between anastomosed to LAD and RCA territory (P =0.2)for LIMA graft.For SV conduits, there was nearly significant difference of patency deterioration among anastomosed to D ,OM,RCA territories and sequential anastomosis(P =0.05),especially anastomosed to D and OM (P =0.02).Conclusion LIMA and SV graft patency decrease with time on serial MDCT.There is higher patency deterioration anastomosed to D for SV conduits.关键词
