肺动脉、支气管动脉双期CTA成像在咯血介入栓塞治疗中的应用价值

Application value of dual-phase CTA imaging of pulmonary artery and bronchial artery in interventional embolization for hemoptysis

目的探讨肺动脉、支气管动脉双期CTA成像在咯血介入栓塞治疗中的应用价值。方法选取本院2015年1月—2018年1月收治的行咯血介入栓塞治疗患者120例,回顾性分析其全部的临床资料,所有患者均接受肺动脉、支气管动脉双期CTA成像诊断,以DSA(数字减影血管造影)为金标准,观察CTA对病变血管检出率以及特异性,并分析其影像表现。结果本组120例患者经肺动脉、支气管动脉双期CTA成像检查,其病变血管检出率79.17%(95/120)、特异性为91.09%(92/101)。结论在咯血介入栓塞治疗中应用肺动脉、支气管动脉双期CTA成像的效果显著,即可达到较高的检出率和特异性,且可对患者病变血管开口位置、形态予以充分了解,并可为患者手术治疗提供可靠的依据。

Objective To investigate the value of dual-phase CTA imaging of pulmonary and bronchial arteries in interventional embolization for hemoptysis.Methods 120 patients with hemoptysis treated by interventional embolization in our hospital from January2015 to January 2018 were selected.The clinical data were retrospectively analyzed.All patients underwent dual-phase CTA imaging diagnosis of pulmonary and bronchial arteries.DSA(digital subtraction angiography) was used as the gold standard to observe the detection rate of CTA for lesions.The imaging manifestations were analyzed.Results 120 patients were examined by dual-phase CTA imaging of pulmonary and bronchial arteries.The detection rate of pathological vessels was 79.17%(95/120) and the specificity was91.09%(92/101).Conclusion Dual-phase CTA imaging of pulmonary artery and bronchial artery is effective in interventional embolization for hemoptysis.It can achieve high detection rate and specificity,and it can fully understand the location and shape of the lesion vascular opening,and provide reliable basis for surgical treatment of patients.
