目的探讨16层螺旋CT血管造影在动脉血管和静脉血管方面的应用价值。方法回顾性分析我院2003年12月～2004年12月用16层螺旋CT血管造影检查101例患者的影像资料。动脉血管造影由上肢静脉注入对比剂,静脉血管造影由下肢静脉注入对比剂,行三维重建。结果101例中男68例,女33例,平均年龄45.6岁。头部CTA35例,发现动静脉畸形5例,动静脉瘘1例,烟雾病1例,动脉瘤2例。颈部血管CTA5例,发现颈部血管迂曲者1例,椎动脉变异者1例,鼻咽癌侵犯血管1例。胸部CTA12例,发现肺动脉栓塞1例,主动脉变异1例,永存动脉干1例。腹部CTA29例,发现肠系膜上动脉栓塞1例,肾动脉栓塞1例。下腔静脉造影5例,发现下腔静脉瘤1例,腹主动脉瘤介入治疗后少量渗漏3例,腹腔巨大畸胎瘤推压肠系膜血管1例。下肢静脉造CTA15例,均见下肢静脉血栓患侧显影浅淡,可见迂曲扩张的侧支循环血管影,健侧显影良好。结论多层螺旋CT血管造影对全身各部位血管病变诊断有重要的临床应用价值。
Objective To investigate the value of 16-slice spiral CT angiography in arterial and venous blood vessels. Methods A retrospective analysis of our hospital from December 2003 to December 2004 using 16-slice spiral CT angiography in 101 patients with imaging data. Arteriovenous angiography contrast agent injection from the upper limb vein, venous angiography from the lower extremity vein contrast agent, three-dimensional reconstruction. Results There were 68 males and 33 females in 101 cases, with an average age of 45.6 years. Head CTA35 cases, found arteriovenous malformations in 5 cases, arteriovenous fistula in 1 case, moyamoya disease in 1 case, aneurysm in 2 cases. Cervical CTA5 cases, found in 1 case of vascular tortuous neck, vertebral artery mutation in 1 case, 1 case of nasopharyngeal carcinoma vascular invasion. Thoracic CTA in 12 cases, found pulmonary embolism in 1 case, 1 case of aortic variability, 1 case of permanent exudate. Abdominal CTA29 cases, found in 1 case of superior mesenteric artery embolization, renal artery embolization in 1 case. Inferior vena cava angiography in 5 cases, found inferior vena cava aneurysm in 1 case, abdominal aortic aneurysm after a small amount of leakage in 3 cases, abdominal peritoneal teratoma push mesenteric vascular in 1 case. Lower extremity venous CTA15 cases, all see the lower limb venous thrombosis developing pale, showing tortuous dilatation of collateral vessels, good contralateral development. Conclusion Multi-slice spiral CT angiography has important clinical value in the diagnosis of all kinds of vascular diseases.
