【摘要】：目的:比较超声和磁共振成像(MRI)对凶险型前置胎盘(Pernicious Placenta Previa,PPP)伴胎盘植入的诊断效能。方法:选择2011年1月至2014年12月在永川妇产医院住院的33例可疑胎盘植入PPP患者为研究对象。所有患者均行超声和MRI检查,并于剖宫产终止妊娠后行病理检查。以手术-病理检查结果为金标准,比较超声与MRI检查对PPP伴植入的诊断效能。结果:经手术-病理检查,26例PPP伴植入(包括:粘连性8例,植入性15例,穿透性3例),7例不伴植入。MRI检查诊断PPP伴植入的准确率(87.88%)略高于超声检查(84.85%),但两种方法间比较差异无统计学意义(P0.05)。结论:超声检查诊断PPP伴植入的准确率与MRI接近,但重复性更好,价格更便宜,可作为本病诊断的首选方法,而将MRI作为辅助检查手段。
[Abstract]:Objective: to compare the diagnostic efficacy of ultrasound and magnetic resonance imaging (MRI) in the diagnosis of (Pernicious Placenta Previa previa PPP with placenta accreta. Methods: 33 patients with suspected placenta accreta (PPP) who were hospitalized in Yongchuan Obstetrics and Gynecology Hospital from January 2011 to December 2014 were selected as study subjects. Ultrasound and MRI were performed in all patients, and pathological examination was performed after caesarean section. The diagnostic efficacy of ultrasound and MRI in the diagnosis of PPP with implantation was compared with the results of surgical-pathological examination as gold standard. Results: 26 cases of PPP with implantation (including 8 cases of adhesiveness, 15 cases of implantation) were examined by surgical and pathological examination. The diagnostic accuracy of PPP with implantation was 87.88% in 7 cases (87.88%) higher than that in ultrasound (84.85%), but there was no significant difference between the two methods (P0.05). Conclusion: the accuracy of ultrasound diagnosis of PPP with implantation is close to that of MRI, but the reproducibility is better and the price is lower, so it can be used as the first choice for the diagnosis of this disease, and MRI is used as the auxiliary examination method.
