Abstract

Objectives: To diagnose coronary artery stenosis by using the postmortem computed tomography angiography (PMCTA), and to explore the diagnostic value of PMCTA in sudden cardiac death.

Methods: Six death cases were selected, and the contrast medium iohexol was injected under high pressure through femoral artery approach with 5F pigtail catheter to obtain coronary image data and then the data was analyzed. The results of targeted coronary imaging and coronary artery calcium score (CaS) were compared with the results of conventional autopsy and histopathological examination.

Results: The autopsy and histopathological examination of cases with coronary artery stenosis obtained similar results in targeted coronary angiography, with a diagnostic concordance rate of 83.3%. Targeted coronary angiography could effectively show coronary artery diseases, and the CaS was consistent with the results of conventional autopsy and histopathological examination.

Conclusions: Targeted coronary angiography can be used as an effective auxiliary method for conventional autopsy in cases of sudden cardiac death.

靶向冠状动脉造影在诊断心脏性猝死中的应用。

目的利用死后计算机断层扫描血管造影术（PMCTA）诊断冠状动脉狭窄，并探讨PMCTA在心脏性猝死中的诊断价值：方法：选取6例死亡病例，用5F尾纤导管经股动脉高压注入造影剂碘海醇，获得冠状动脉图像数据，然后对数据进行分析。将冠状动脉靶向成像和冠状动脉钙化评分（CaS）结果与常规尸检和组织病理学检查结果进行比较：结果：冠状动脉狭窄病例的尸检和组织病理学检查结果与靶向冠状动脉造影结果相似，诊断吻合率为 83.3%。靶向冠状动脉造影能有效显示冠状动脉疾病，CaS与常规尸检和组织病理学检查结果一致：结论：在心脏性猝死病例中，靶向冠状动脉造影可作为常规尸检的有效辅助方法。
