超声检查应用于诊断植入性凶险型前置胎盘的价值

Ultrasonography in Diagnosis of Placenta Previa with Placenta Accreta

目的:探讨超声检查应用于诊断植入性凶险型前置胎盘(PPP)的价值。方法:回顾性分析31例疑诊植入性PPP孕妇的影像资料及手术病理检查资料。以手术-病理检查结果为诊断金标准,评价并比较超声检查与MRI检查对植入性PPP的诊断效能。结果:在31例拟诊为植入性PPP中,23例为植入性PPP;8例经手术-病理检查确诊为非植入性PPP。超声检查诊断植入性PPP的符合率略低于MRI检查,但两种检查方法比较差异无统计学意义(P>0.05)。结论:超声检查对植入性PPP的诊断效能与MRI接近,但重复性更好,价格更便宜,故可作为本病诊断的首选方法。

Objective:To discuss the efficacy of ultrasonography in diagnosis of implanted pernicious placenta previa(PPP).Method:The imagingand clinical data of pregnant women was analyzed retrospectively,who suspected with implanted PPP.In operation-pathological findings as the gold standard,evaluated and compared the efficacy of ultrasonography and MRI in diagnosis of implanted PPP.Result:Among31cases of patients suspected with implantedPPP,23cases were confirmed as implanted PPP by operation and pathology,and the other8cases were diagnosed with non implanted PPP.The coincidenceof ultrasonography in diagnosis of implanted PPP were lower than that of MRI,however,there was no significant difference between the two methods(P>0.05).Conclusion:The efficacy of ultrasonography in diagnosis of implanted PPP are close to MRI,and the repeatability is better and the price is cheaper,it can beused as the preferred method for diagnosis.
