| 目的 探讨320排CTA在主动脉夹层(AD)诊断中的价值。方法 回顾分析59例临床诊断AD患者的320排CTA检查资料,对比其与16排CTA、MRA及DSA的差异。结果 59例AD患者中,3种方法共诊断AD 43例,胸主动脉瘤4例,真性腹主动脉瘤9例,假性腹主动脉瘤3例。320排CTA诊断AD破口位置的准确率(75/77,97.40%)高于16排CTA(47/53,88.68%,χ2=4.14,P<0.05)及MRA(40/46,86.96%,χ2=5.17,P<0.05);其电离辐射剂量 低于16排CTA 及DSA (t=2.51,P<0.05),并可清晰显示内膜片、真假腔、血栓形成及主要内脏动脉分支受累情况。结论 320排CTA是诊断AD的安全、快捷、有效且无创的方法,对临床制定治疗方案有重要应用价值。 |

| Objective To explore the value of 320-detector CT angiography (CTA) in diagnosis of aortic dissection (AD). Methods A total of 59 consecutive patients with suspected AD were enrolled. The results of 320-detector CTA with 16-detector CTA, MRA and DSA were compared. Results Totally 43 patients were diagnosed with 3 methods as AD, 4 with thoracic aorta aneurysm, 9 with abdominal aorta aneurysm and 3 with false abdominal aorta aneurysm. The diagnostic accuracy rate for preoperative revealing of the tears of 320-detector CTA (75/77, 97.40%) was higher than that of 16-detector CTA (47/53, 88.68%, χ2=4.14, P<0.05) and MRA (40/46, 86.96%, χ2=5.17, P<0.05). The dose of radiation in examination of 320-detector CTA ( mGy) was lower than that of 16-detector CTA ( mGy, t=2.84, P<0.05) and DSA ( mGy, t=2.51, P<0.05). In addition, 320-detector CTA was able to display the intimal flap, the real and false lumen, the thrombus in false lumen and detail of significant branches of aorta. Conclusion 320-detector CTA is secure, quick, effective and noinvasive in diagnosing AD, thus has important clinical value in drawing up the treatment plan of AD. |
