The Application Of Duct Plastic Technology In Complex Coronary Intervention Diagnosis And Treatment

Objective:Observe the application of catheterization technique in the diagnosis and treatment of complicated coronary artery disease and summarize the experience of catheterization in this center.Methods:The research is divided into two parts,the first part is adopted a single center,randomized,single-blind,parallel-group controlled design was used in this study and159 patients were enrolled in the First Affiliated Hospital of Chengdu Medical College who has failed for the first time by using 5F tiger I catheter angiography and Using digital table method were randomly divided into two groups,in the control group(79cases),the patients were treated with transradial coronary angiography was performed using 6FJudkins and its Amplatz-supplemented catheter.The experimental group(80cases)was treated with using of the multi-function 5FtigerI angiography Catheter shaping technology through the radial artery coronary angiography.Compare the coronary angiography Surgical success rate,X-ray fluoroscopy time,amount of radiation,dose of contrast agent,number of catheters,operation time and surgical complications of the two groups.In the second part,case reports were used to investigate the application of Judkins left(JL)guided catheterization in the interventional treatment of 3 cases of right coronary artery originating from the aortic sinus(AORCA).The success rate of operation,X-ray Fluoroscopy time,dose,dose of contrast agent,number of catheters used,duration of operation,and surgical complications.Results:Part I:(1)Compared with the control group,the number of catheters required for complex coronary angiography in the experimental group[(1.30 ± 0.56)vs.(2.47 ±0.57),P = 0.001)] and radiation dose [230(175.25,274.5)vs 267(230,321),P<0.001],The dose of contrast agent [(54.56 ± 8.24)vs(61.78 ± 7.88),P = 0.001],the time of X-ray exposure [(4.17 ± 1.67)vs(4.78 ± 1.51),P = 0.03],the operative time [21.6(18.9,25.38)vs 26.8(23.4,31.4),P <0.001],there were significantly lower than those in the control group(P <0.05);The operative success rate was significantly higher in the control group than that in the experimental group[(98.7%(78/79)vs 97.5%(78/80)],P=0.567],but,there was no significant difference between the two groups(P> 0.05).(2)Using plasticity stratification,The experimental group had lower radiation dose,operation time and exposure time than the control group in Class A and C reasons,but,There was no significant difference between the two groups(P> 0.05).The experimental group was lower than the control group in the cause of class B and differences were statistically significant(P <0.05).Part II: In 3 patients,aged 65-76 years,3 cases were acute inferior myocardial infarction(MI).One patient was treated via the femoral artery and the other 2 patients were treated via the radial artery.The median time and ray time for the intervention were 62 min and 15 min,respectively,and all patients had successful revascularization without complications.Conclusion:(1)For complex coronary angiography,the use of 5FtigerI catheter plasticization technology compared with the replacement 6FJudkins imaging success rate quite good,and good security.(2)For the pathological changes of abnormal RCA caused byLSOV,the catheterization technique of JL guiding catheter on the Judkins side was safe and effective.
