MRI诊断腹腔妊娠

MRI diagnosis of abdominal pregnancy

目的探讨MRI在诊断腹腔妊娠与患者临床管理中的应用价值。方法回顾性分析经手术证实的5例腹腔妊娠患者的MRI和临床资料,分析其MRI表现,并与手术结果对照。结果 5例产前MRI均准确诊断腹腔妊娠,其中1例为原发性,4例为继发性,并发现子宫破裂口的位置;5例胎盘MRI表现与手术结果相吻合;1例MRI检出腹腔大量新鲜出血,2例显示羊水过少,2例检出胎儿和脐带异常,均与手术所见相符。结论术前MRI诊断腹腔妊娠准确率较高,可显示胎儿和胎盘及其与周围组织关系,有助于规划临床管理。

Objective To observe the application value of MRI in diagnosis and clinical management of abdominal pregnancy. Methods MRI and clinical data of 5 patients with abdominal pregnancy proved surgically were analyzed retrospectively. MRI performances were analyzed and compared with findings in operation. Results Prenatal MRI correctly diagnosed abdominal pregnancy in all 5 patients, including 1 case of primary and 4 cases of secondary abdominal pregnancy. The position of uterine rupture was revealed in all 4 cases of secondary abdominal pregnancy. MRI performances of placenta conformed to operative findings in all 5 patients. A lot of fresh intra-abdominal hemorrhage was found in 1 case, oligohydramnion in 2 cases, and abnormalities of placenta and fetus in 2 patients, which were consistent with findings of operation. Conclusion Prenatal MRI offers a high accuracy rate in diagnosis of abdominal pregnancy. MRI can show fetus, placenta and the relationship with surrounding tissue, therefore being helpful to clinical management of abdominal pregnancy.
