CTA技术在外周血管闭塞诊断中的应用探讨

Application of CTA Technology in Diagnosis of Peripheral Vascular Occlusion

目的讨论CT血管成像(CTA)技术在外周血管闭塞性疾病诊断中的应用价值。方法对我科3年间外周血管闭塞患者74例的影像资料进行回顾性诊断分析,分析CTA在血管闭塞症的影像特点。结果 74例患者共诊断415处狭窄,2级狭窄191处占46%、3级狭窄138处占33%、4级狭窄54处占13%、5级狭窄32处占8%;钙化253处,其中,轻度钙化148处占58.5%、重度钙化105处占41.5%。结论 CTA作为一种无创的检查手段,在怀疑患者下肢动脉闭塞时可以作为首选的检查方法。

Objective To evaluate the effects of application of CTA technology in diagnosis of peripheral vascular occlusion. Methods Through retrospective diagnostic analysis of imaging records from 74 cases of patients who were treated for peripheral vascular occlusion in our department in three years, imaging characteristics with application of CTA on vascular occlusive diseases are summarized. Results Four hundred and fifteen stenoses and two hundred and fifty three calcification symptoms are diagnosed in 74 patients, among which there are 191 Level II stenoses accounting for 46%; 138 Level III stenoses accounting for 33%; 54 Level IV stenoses account for 13%; 32 Level V stenoses account for 8%; 148 symptoms of slight calcification accounting for 58.5% and 105 symptoms of severe calcification accounting for 41.5%. Conclusion As a noninvasive examination method, CTA shall be regarded to be a top priority for examination of patients who were suspected with peripheral arterial occlusion.
