摘要
目的：探讨多层螺旋CT血管造影（MSCTA）在诊断头颅动脉瘤及术后随访中的临床价值。方法：回顾性分析121例临床高度怀疑动脉瘤患者的头颅MSCTA及DSA影像资料，确诊后经外科手术或介入栓塞治疗后复查MSCTA及DSA，确诊病例均经手术或介入治疗证实。结果：121例患者中动脉瘤患者116例（动脉瘤124个），其中3例患有多发动脉瘤，分别有3、4、4个动脉瘤，MSCTA诊断125个动脉瘤，4个误诊，正确诊断121个，MSCTA检出率为97.6%；DSA诊断123个动脉瘤，误诊3个，漏诊4个，而且MSCTA所发现的动脉瘤中DSA检出率为96.7%，两种方法在检出率上比较，差异无统计学意义（P＞0.05）。结论：MSCTA检查具有微创、快速、准确的优点，并发症极少，拥有强大的后处理功能，可清晰显示动脉瘤的所在部位、数目、大小、范围及其与周围结构组织之间关系，可以较为正确的诊断及评估术后所放弹簧栓的位置、形态，能观察动脉瘤是否完全闭塞、载瘤动脉的通畅情况以及动脉瘤颈是否完全栓塞，可作为诊断颅内动脉瘤及术后随访的首选检查方法，具有极高的临床应用价值。
Abstract
Objective: To study the clinical application value of multislice spiral CT angiography(MSCTA) in the diagnosis of intracranial aneurysms. Methods: The MSCTA and DSA imaging data of 121 cases highly suspected of intracranial aneurysm were analysed retrospectively. All cases were comfirmed by surgical operation or interventional embolization. After treatment all cases were given MSCTA and DSA re-examinations. Result: In the 121 patients, 116 patients had intracranial aneurysm(altogether 124 aneurysms), while in 3 cases there were 3, 4 and 4 aneurysms respectively. MSCTA gave correct diagnosis in 121 aneurysms and misdiagnosed in 4 with a detection rate of 97.6%, DSA detected 123 aneurysms, misdiagnosed in 3 and 4 miss diagnosed. The detection rate of DSA was 96.7%. There was no significant difference of detection rate between the two examinations(P>0.05). Conclusion: MSCTA has minimal invasion, fast, accurate, with very few complications, and powerful post-processing capabilities. It is a method of choice for the diagnosis of intracranial aneurysms.
