| Objecti vesThrough the application of 64-slice CT observe the patency of vascular bridge after coronary artery bypass grafting observed (CABG), observation after taking qi and promoting blood circulation to conventional medicine with phlegm western medicine therapy and conventional western medicine treatment of patients vascular patency rate of bridge, and contrast similar reported in the literature, this paper discusses related by qi and promoting blood circulation expectorant herbal treatment of patients after CABG surgery, the influence of vascular bridge for further prevention CABG postoperative patients vascular bridge then plugging has the extremely vital significance.Method1. Were analyzed retrospectively collected by research,1998-2010 already do this center cases of intraoperative CABG patients with data were 60 people, telephone, review cases, to build a statistical database follow-up. According to expose factors, namely, whether meet benefit qi and activate blood circulation expectorant treatments for divided into two groups. The treatment group:receive benefit qi and activate blood circulation expectorant method with traditional Chinese medicine, western medicine therapy conventional The control group:no connect benefit qi and activate blood circulation, TCM treatment method of resolving phlegm only accept conventional routine medicine. Both groups were controlled within five years,10 years patency of vascular bridges.2. Already do to all 64-slice CT examination coronary situation of patients statistics, assess vascular bridge unobstructed respectively. CT image reconstruction:use workstation respectively, the several different phase cross-sectional images window reappear reconstruction, two-dimensional volume curved surface reconstruction (2D reformating) and maximum density projection reconstruction, vessels, to reconstruct the bridge of the left coronary artery, the left anterior descending, left circumflex coronary artery branches and right and its major branch of blood vessels. By contrast enhancement depending on conditions at both ends of vascular diameter stenosis site reference evaluation bypass vascular proximal anastomotic, bypass vascular itself, distal anastomotic and other parts of the unobstructed, coronary artery blood vessels and their coronary stenosis bridge was analyzed and appraised, judge degree sexual. The artery open bridge Image quality solidifying were used respectively evaluation. Image Hemal stricture classification adopted the usual visual diameter law:namely hemal stricture degree=(narrow end nearly heart end normal blood essels in a narrow diameter stenosis diameter)/the diameter of normal blood essels heart end nearly 100% x. According to the four narrow judging:(1) the degree of flow; (2) the mild narrow (< 50%); (3) 50% in heavy narrow (p); (4) block. Evaluation methods diagnosis by guangdong hospital of traditional Chinese medicine, senior imaging experts comprehensive various imaging method to obtain the result.3. Clinical data results in a database, data management, application SPSS17.0 packages for statistical analysis of the data:measurement data and compares the X2 inspection in groups, back and forth between groups matched data and compared with the independent sample t-test.ResultBoth treatments are clearly the curative effects of patients internal mammary artery bridge, and the comparative study of venous bridge, the results show that:internal mammary artery bridge between the two groups in the curative effect of no obvious difference; Venous bridge aspects:postoperative five years than the control group, the treatment group has obvious curative effect, fie years to 10 years, two groups of differences, but still see little, the treatment group than in control group.ConclusionQi and promoting blood circulation expectorant herbal treatment can improve the blood vessels in postoperative patency rate bridge, a regular routine medicine has obvious curative effect.
