64排螺旋CT在发绀型先天性心脏病肺血管成像中的应用△

目的评价64排螺旋CT（multislice spiral computed tomography，MSCT）对于发绀型先天性心脏病肺血管成像的临床应用价值。方法回顾335例发绀型先天性心脏病患者的64排螺旋CT影像学资料，男218例，女117例，年龄1d-37岁，中位年龄4岁。其中152例曾行手术治疗，另42例同时行血管造影术（cardioangiography，CAG）检查，对比其结果并进行统计学分析。结果152例患者经手术证实肺血管共有271处畸形。64排MSCT确诊258处畸形，符合率95．2％（258／271）。42例患者经手术证实109处畸形，64排MSCT确诊102处畸形，符合率93．6％（102／109）；CAG确诊106处畸形，符合率97．2％（106／109）。MSCT和CAG对比，诊断符合率差异无统计学意义（P〉0．05）。结论64排MSCT对发绀型先天性心脏病肺血管畸形的诊断有较高的符合率，且快捷、无创，具有较高的临床应用价值。

Clinical application of 64-slice multislice spiral computed tomography in imaging of pulmonary vascular in cyanotic heart disease

Objectives To evaluate the accuracy of 64 slice muhislice spiral computed tomography （64 slice MSCT） in the imaging of the pulmonary vascular in cyanotic heart disease. Methods We retrospectively analyzed 335 patients with cyanotic heart disease （218 men and 117 women, the age ranged from 1 d to 37 years, mean 4 years） who underwent 64 slice MSCT. Among them, 152 patients underwent surgery; 42 patients underwent 64 slice MSCT and cardioangiography （CAG） , the results were compared with surgical finding. The data were analyzed statistically. Results There were 271 deformities confirmed by surgery in 152 patient. 64 slice MSCT in the evaluation of the pulmonary vascular in cyanotic heart disease was 95.2% （258/271）. There were 109 deformities confirmed by surgery in 42 patient, 64 slice MSCT and CAG in the evaluation of the pulmonary vascular in cyanotic heart disease were 93.6% （102/109） and 97.2% （106/109）, respectively. The differences between 64 slice MSCT and CAG were not significant. Conclusions 64 slice MSCT has high accuracy in the evaluation of the pulmonary vascular in cyanotic heart disease. 64 slice MSCT is a valuable technique for demonstrating pulmonary vascular in cyanotic heart disease.
