目的:探讨Ⅲ级系统产前超声检查诊断闭合性脊柱裂的临床意义。方法:回顾性分析本院Ⅲ级系统产前超声检查诊断闭合性脊柱裂6例及Ⅰ级产前超声检查漏诊闭合性脊柱裂1例。结果:6例Ⅲ级系统产前超声检查诊断闭合性脊柱裂均无脑部声像学改变,仅见脊柱骶尾部隆起小包块,局部皮肤连续性完好,脊柱骶尾部2条串珠状强回声带间隙增宽,不能相互靠拢,且隆起小包块与增宽间隙相连,与引产后结果相符。1例Ⅰ级产前超声检查漏诊病例生后亦见骶尾部隆起小包块,皮肤连续性好,X线片证实L5隐性脊柱裂。结论:Ⅲ级系统产前超声检查由于规范系统扫查脊柱,对有包块型闭合性脊柱裂有一定临床意义。
Objective: To investigate the clinical significance of Ⅲ system prenatal ultrasound in diagnosing closed spina bifida. Methods: 6 cases of closed spina bifida were diagnosed by prenatal ultrasonography in our hospital and 1 case of closed spina bifida were missed by prenatal ultrasound examination. Results: Six cases of grade Ⅲ system prenatal ultrasound examination of the diagnosis of closed spina bifida did not change the brain ultrasound, only the sacral caudate bulge mass, local skin continuity intact, spinal sacrococcygeal 2 beacons with strong echo gap Widened, can not move closer to each other, and the bulge of small pieces connected with the widening gap, consistent with the results after induction of labor. A case of grade Ⅰ prenatal ultrasound missed diagnosis of cases also see sacrococcygeal bulge mass, skin continuity, X-ray confirmed L5 recessive spina bifida. Conclusion: The Ⅲ system prenatal ultrasound examination of the spine because of the normative system, has a block type of closed spina bifida has some clinical significance.
