目的:探讨多层螺旋CT心血管参数对急性肺栓塞严重性的评价。方法:将47例急性肺栓塞患者,按病情严重程度分为严重组(17例)与非严重组(30例)。比较两组患者在CT阻塞指数,左、右室短轴最大径,RV/LV短轴比,右室壁厚,上腔静脉直径,肺动脉直径等心血管参数的差异。结果:严重组患者CT阻塞指数、右室短轴最大径、RV/LV短轴比、右室壁厚、上腔静脉直径、肺动脉直径及室间隔左突比率明显高于非严重组,而左室短轴最大径明显低于非严重组,差异有统计学意义(P<0.05)。结论:急性肺栓塞患者通过CT检查一方面可以对急性肺栓塞进行准确诊断,另一方面还能心血管参数有效的判断患者急性肺栓塞的严重程度,对患者的及时治疗、预后具有重要的临床意义。
Objective: To evaluate the evaluation of the severity of acute pulmonary embolism by multi-slice spiral CT. Methods: 47 patients with acute pulmonary embolism were divided into severe group (17 cases) and non-severe group (30 cases) according to the severity of the disease. The differences of the cardiovascular parameters between the two groups were compared in terms of the CT block index, the maximum diameter of the left and right ventricular minor axis, the short axis ratio of RV / LV, the wall thickness of the right ventricle, the diameter of the superior vena cava, and the diameter of the pulmonary artery. Results: In the severe group, the CT obstruction index, the maximum diameter of the right ventricular minor axis, the short axis ratio of RV / LV, the wall thickness of the right ventricle, the diameter of the superior vena cava, the diameter of the pulmonary artery, and the left ventricular remodeling ratio were significantly higher than those in the non-severe group The maximum diameter of short axis was significantly lower than the non-severe group, the difference was statistically significant (P <0.05). Conclusion: Acute pulmonary embolism patients can be diagnosed acute pulmonary embolism by CT scan on the one hand, but also can determine the severity of acute pulmonary embolism in patients with cardiovascular parameters, and it has important clinical treatment for patients with timely treatment and prognosis significance.
