64层螺旋CT冠状动脉血管造影临床应用探讨

目的探讨多层螺旋CT冠脉造影(MSCTCA)对冠脉疾病的临床应用价值。方法对150例胸痛患者进行MSCTCA检查,分析其对冠脉的显示能力,冠脉斑块性质及钙化程度,评价管腔狭窄程度及支架术后支架的显示及通畅性。结果在145例患者中38例排除冠心病,107例冠脉不同程度狭窄,检出中、重度狭窄共84处。发现斑块112个,软斑块26个,混合性斑块47个,钙化斑块39个,钙化积分为3～1890。5例冠脉支架放置术后患者均表现为支架通畅,且经随访半年未出现临床胸痛等症状。结论MSCTCA可作为冠心病的筛查手段及在冠脉支架安置术后的复查中有很高的临床应用价值。

Clinical application of 64 -slice spiral CT coronary angiography

Objective To assess the clinical value of multislice spiral CT coronary angiography(MSCTCA).Methods 64-slice spiral CT coronary angiography(MSCTCA) were all applied in 150 patients because of chest pain and the CT images were reconstructed by several methods to analyze the ability of MSCT displaying the coronary artery vessels,along with the nature and calcification degrees of the plaques.The presence as well as the degree of vascular stenosis,implanted stents and patency of the vessels were evaluated.Results In 145 patients,MSCT show 35 vessels with light stenosis,41 vessels with middle stenosis and 43 vessels with high-grade stenosis.Then the diagnosed plaque was 112 and flexible plaque,middle plaque and calcify plaque were 26,47 and 39 respectively.Reconstructive coronary artery images of 5 patients were displayed clearly and shape and position of coronary arterial stent were clearly demonstrated.Conclusion MSCTCA has a good clinical value in the primary identification of coronary heart disease and reexamination after revascularization.
