病人和平时就诊检查时一样,躺在检查床上,医生从大腿上的股动脉处或是手腕处的桡动脉穿刺,插入专用导管,由导管向冠脉内注入造影剂,根据显影图像来判断是否存在冠脉狭窄等情况。如果有明显狭窄,即可进行球囊扩张或是支架植入。诊断和治疗可以一次完成,也可以分次完成。该技术操作所需时间短,病人无明显痛苦,操作完毕后休息几小时或是一天,患者就可如平时一样活动。冠状动脉造影是目前冠心病诊断的金标准。 The patient was on the examination bed in the same way as the usual examination. The doctor punctured the radial artery at the femoral artery or the wrist of the thigh and inserted a special catheter. The contrast medium was injected into the coronary artery through the catheter. The judgment was made according to the developed image There are coronary stenosis and so on. If there is obvious stenosis, you can balloon expansion or stent implantation. Diagnosis and treatment can be completed in one time, you can also complete the sub-level. The technique requires less time to operate, the patient has no apparent pain, and the patient can be as active as usual, resting hours or days after the operation is completed. Coronary angiography is the gold standard for the diagnosis of coronary heart disease.
