CTA与超声诊断主动脉壁内血肿的价值对比

Comparison on the Value of CTA and Ultrasound in the Diagnosis of Aortic Intramural Hematoma

目的对比CTA与超声诊断主动脉壁内血肿(AIH)的临床价值。方法选取2022年2月至2024年1月本院收治的60例疑似AIH患者,均自愿接受CTA及超声检查。以DSA为参照,比较CTA及超声诊断AIH的临床价值。结果60例疑似AIH患者经DSA检查明确55例为AIH,5例为主动脉夹层。55例AIH患者中Stanford A型13例(23.64%),Stanford B型42例(76.36%)。CTA检查对主动脉壁增厚、钙化内移、穿透性溃疡、胸腔积液的检出率高于超声(P<0.05)。CTA诊断AIH的灵敏度、准确度分别为98.18%、98.33%,高于超声的81.82%、81.67%(P<0.05)。结论CTA检查可清晰观察AIH的位置、厚度、累及范围等,是临床诊断AIH的有效方式。

Objective To compare the clinical value of CTA and ultrasound in the diagnosis of aortic intramural hematoma(AIH).Methods 60 patients with suspected AIH admitted to our hospital from February 2022 to January 2024 were selected and given voluntary CTA and ultrasound examination.Using DSA as reference,the clinical value of CTA and ultrasound in the diagnosis of AIH was compared.Results Of 60 suspected AIH patients,55 cases were confirmed as AIH by DSA examination,and 5 cases were confirmed as aortic dissection.Among the 55 AIH patients,13 cases(23.64%)were Stanford type A and 42 cases(76.36%)were Stanford type B.The detection rates of aortic wall thickening,calcification,penetrating ulcer and pleural effusion of CTA were higher than those of ultrasound(P<0.05).The sensitivity and accuracy of CTA in the diagnosis of AIH were 98.18%and 98.33%,respectively,higher than 81.82%and 81.67%of ultrasound(P<0.05).Conclusions CTA can clearly observe the location,thickness and scope of AIH,which is an effective way for clinical diagnosis of AIH.
