The Value of 256-Slice Spiral CT Angiography in Internal Thoracic Artery / 天津医药

ABSTRACT

Objective To study the value of 256-slice spiral CT (MSCT) in internal thoracic artery. Methods The angiographic images of 107 patients who were suspected thoracic and abdominal aortic diseases were retrospectively ana-lyzed. The running rule and branches of internal thoracic artery on both sides were observed. Each side of the internal thorac-ic artery was divided into 3 sections according to the running rule. The lumen diameter, vessel length and its branches were measured in three segmental vascular of the internal thoracic artery. The lumen diameter of the diaphragmatic artery diame-ter,and the distance between internal thoracic artery and each border of the sternum were also measured. Results Both sides of the internal thoracic and diaphragmatic arteries were shown in 107 patients (100%). There were significant differenc-es in vascular lumen diameter of intrathoracic artery of both sides (P＜0.05). There were no significant differences between both sides of the corresponding segments (P>0.05). The left internal thoracic artery was significantly longer in the left side than that of right side (P＜0.05). There were no significant differences between the diameter of diaphragmatic arteries and the distance between the internal thoracic artery and the sternal edge of two sides (P>0.05). Conclusion The application of 256-slice spiral CT angiography can clearly show the running rule and anatomical features of internal thoracic artery ,and provide a relatively important clinical information.
