摘要
目的:观察超声超微血流成像技术(SMI)对Stanford B型主动脉夹层患者真假腔的鉴别诊断效果及腹主动脉分支动脉受累的诊断效果。方法:回顾分析丹东市第一医院2015年12月至2020年12月期间收治的100例Stanford B型主动脉夹层患者资料,依据不同影像学诊断方法将其分为SMI检查组(60例)与常规超声检查组(40例),均以数字血管减影造影术(DSA)检查为诊断“金标准”,观察比较SMI检查组、常规超声检查组两组真假腔的鉴别情况以及腹主动脉分支动脉受累情况。结果:SMI检查组真假腔的鉴别诊断符合率(96.67%)显著高于常规超声检查组(62.50%),差异有统计学意义(χ^(2)=10.427,P<0.05);SMI检查组腹主动脉分支动脉受累诊断符合率(83.33%)显著高于常规超声检查组(65.00%),差异有统计学意义(χ^(2)=4.423,P<0.05)。结论:相较于常规超声诊断,超声超微血流成像技术运用于Stanford B型主动脉夹层诊断,可更准确地鉴别主动脉夹层患者真假腔情况及检测主动脉夹层患者腹主动脉分支动脉的受累状况,诊断的符合率较高,能够为临床相关诊治以及对预后的评估提供有价值依据。
Objective:To observe the differential diagnosis effect of super mircovascular imaging(SMI)in Stanford B aortic dissection patients with true and false lumen and abdominal aortic branch artery involvement.Methods:Retrospective analysis was performed on the data of 100 patients with Stanford B aortic dissection admitted to Dandong First Hospital from December 2015 to December 2020,and,according to different imaging diagnosis methods,they were divided into SMI group(60 cases)and conventional ultrasound group(40 cases),both with digital subtraction angiography(DSA)as the"gold standard".True and false lumen,and abdominal aorta branch artery involvement were identified in both groups.Results:The coincidence rate of differential diagnosis of true and false cavities in SMI group(96.67%)was significantly higher than that of conventional ultrasound examination group(62.50%),and the difference was statistically significant(χ^(2)=10.427,P<0.05);the coincidence rate of diagnosis of abdominal aortic branch artery involvement in group SMI group(83.33%)was significantly higher than that of conventional ultrasound examination group(65.00%),and the difference was statistically significant(χ^(2)=4.423,P<0.05).Conclusion:Compared with conventional ultrasound diagnosis,ultrasonic super mircovascular imaging technology is used more accurately in the diagnosis of Stanford B-type aortic dissection,which can identify the true and false lumen of patients with aortic dissection and detect the involvement of abdominal aorta branch arteries in patients with aortic dissection,and the diagnostic coincidence rate is higher,which can provide a valuable basis for clinical diagnosis and treatment and prognosis evaluation.
