【摘要】：目的：探讨胸廓内动脉（nternal Thoracic Artery，ITA）在多层螺旋CT血管造影(MSCTA)的影像学显示情况及解剖变异情况，为临床相关疾病的治疗提供可靠的影像学依据。方法：正常组：正常受检者80例（男40例，女40例）经过胸部多层螺旋CT增强扫描，分别测量胸廓内动脉主干的长度（lITA）及其内径（dITA）、胸廓内动脉与锁骨下动脉(subclavian artery，SA)近侧端的夹角（aITA/SA）、胸廓内动脉起点距主动脉的长度（l（A-I））。变异组：回顾性研究18例完成胸部增强扫描后发现的ITA解剖变异患者（男11例，女7例），并分析其变异的临床意义。结果： 1.98例受检者ITA主干均能清晰显示，显示率为100%（100／100），其中18例发生变异，变异率为18.37％（18／98），其中， ITA与其他动脉共干发出者共10例（左侧6例，右侧4例），ITA呈波浪状走行的共8例（左侧3例，右侧2例，双侧3例）。 2.相关影像学指标（lITA、dITA、l（A-I）、ITA/SA）显示清晰，，并且对指标进行精确的测量后经统计学分析：①lITA在性别间差异有统计学意义（p＜0.05），在不同侧间差异无统计学意义（p＞0.05）；②dITA及l（A-I）在侧别间差异有统计学意义（p＜0.05），在性别间差异均无统计学意义（p＞0.05）；③aITA/SA在不同性别、不同侧间差别均无统计学意义（p＞0.05）。结论： 1、多层螺旋CTA技术能很好的观察胸廓内动脉的正常解剖，并能准确测量双侧胸廓内动脉的相关解剖学数据。 2、胸廓内动脉的起始位置及解剖变异类型表现多样化，多层螺旋CTA技术可以确切地显示其变异情况。 3、多层螺旋CTA技术能够较好的为胸腹部手术、ITA-冠脉搭桥术及ITA相关介入手术做好术前评估，为治疗方案的确定提供完善的临床资料。
[Abstract]:Objective: To investigate the imaging manifestation and anatomic variation of internal thoracic artery Thoracic Arteryitas in multislice spiral CT angiography (MSCTA), and to provide reliable imaging evidence for the treatment of clinically related diseases. Methods: In the normal group, 80 normal subjects (40 males and 40 females) underwent multi-slice spiral CT enhanced chest scanning. The length of the main trunk of the internal thoracic artery and its internal diameter were measured respectively. The angle between the internal thoracic artery and the subclavian artery of the subclavian artery was measured. The length of the internal thoracic artery from the origin of the internal thoracic artery to the aorta was measured. Mutation group: 18 patients (11 males and 7 females) with anatomic variation of ITA found after chest enhanced scanning were retrospectively studied and their clinical significance was analyzed. Results: 1.The trunk of ITA was clearly displayed in 98 subjects, and the display rate was 100% / 100%, of which 18 cases were mutated, and the variation rate was 18.37% / 98%. Among them, there were 10 cases (6 cases on the left) of ITA and other arterial trunk. There were 8 cases (3 left, 2 right and 3 bilateral) of Ita in the right (4 cases) with a wave-like pattern (3 cases on the left side, 2 cases on the right side and 3 cases on the bilateral side). 2. The relevant imaging indicators, lITAA / IIA / SAA, were clear. And after the accurate measurement of the index, the statistical analysis showed that there was significant difference between the two sexes (p < 0.05), but there was no significant difference between the two sides (p > 0.05) and the difference between the two sides was statistically significant (p < 0.05), and the difference between the two sexes was significant (P < 0.05). There was no significant difference between the two groups (P > 0.05) and 3aITAP / SA in different sex. There was no significant difference between the two sides (p > 0.05). Conclusion: 1. Multilayer spiral CTA technique can observe the normal anatomy of the internal thoracic artery and accurately measure the anatomical data of the bilateral internal thoracic artery. 2. The origin and anatomic variation of the internal thoracic artery are varied. Multilayer spiral CTA technique can accurately show the variation of the internal thoracic artery. 3. The multilayer spiral CTA technique can provide a good preoperative evaluation for the thoracoabdominal surgery and ITA related interventional surgery, and provide perfect clinical data for the determination of the treatment plan.
