摘要
目的 :探讨主动脉窦瘤破裂的MRI表现及其临床应用价值。材料和方法 :经手术证实的主动脉窦瘤破裂 2 3例 ,其中无冠状窦破入右心房 3例 ,右冠状窦破入右心房 4例、右心室 15例和肺动脉 1例。术前均行X线平片、超声心动图和MRI检查 ,9例行心血管造影检查。结果 :MRI正确诊断 19例。典型表现为窦壁信号中断 ,破裂处窦壁漂入相邻心腔 ,此征象亦为鉴别诊断的主要依据。结论 :MRI是诊断主动脉窦瘤破裂的有效方法 ,辅助超声心动图检查 ,可提高对该病的诊断水平。
Purpose:To evaluate the MRI findings and clinical application in the rupture of aortic sinus aneurysm(RASA). Materials and Methods:23 cases of RASA confirmed by the operation were examined by X-ray?Echocardiography and MRI,9 cases of them were examined by cardioangiography(CAG). Among them,the non-coronary sinus of Valsalva aneurysm ruptured into the right atrium in 3 cases,the right coronary sinus of Valsalva aneurysm ruptured into the right atrium in 4 cases,into the right ventriculum in 15 cases and into the pulmonary artery in 1 case. Results:19 cases were diagnosed correctly by MRI. The typical findings of MRI were that the sinus wall interrupted and drifted into the adjoining heart cavity at the ruptured part,which was the major point of the differential diagnosis. Conclusion:MRI is the effective modality in diagnosing the RASA,echocardiography and MRI could improve the non-invasive diagnostic level.
