心肌桥CTCA检查与心肌灌注检查对照研究

A Comparative Study between Myocardial Perfusion SPECT and CTCA in Myocardial Bridge

目的探讨多层螺旋CT(MSCT)检查发现的心肌桥-壁冠状动脉患者核素心肌灌注情况。资料与方法将MSCT检查发现肌桥同时1个月内行核素心肌灌注检查者87例分为浅肌桥组(n=36)和深肌桥组(n=51),统计两组核素心肌灌注检查阳性病例数。结果 36例浅肌桥核素心肌灌注检查未见阳性发现,51例深肌桥组3例核素心肌灌注检查阳性,两组阳性率差异无统计学意义(χ2=0.78,P>0.05)。结论 MSCT发现的肌桥只有少数具有核素心肌灌注异常,即有病理、生理意义。

Objective To study the image results of myocardial perfusion single photon emission computed tomography（SPECT）in patients found myocardial bridge（MB）-mural coronary artery by multislices computed tomography coronary artery（CTCA）.Materials and Methods 87 patients found myocardial bridge using multislices computed tomography coronary artery（CTCA）performed myocardial perfusion SPECT within one month.The cases were divided into shallow myocardial bridge group（36 cases）and deep myocardial bridge group（51 cases）.And then count cases in two groups with positive findings in SPECT.Results 3 cases of deep myocardial bridge group had positive findings in SPECT（χ^2=0.78,P〉0.05）.All the 36 cases of shallow myocardial bridge group had negative finding in SPECT.Conclusion Few of all cases found MB in multi-slices CTCA has positive findings in myocardial perfusion SPECT,in other words,few of all cases found MB in CTCA has pathologic physiology significance.
