产前超声诊断胎儿卵巢囊肿蒂扭转的临床价值

Application value of prenatal ultrasound in the diagnosis of fetal ovarian cyst torsion

目的探讨产前超声诊断胎儿卵巢囊肿蒂扭转的临床价值。方法回顾性分析我院6例经产后确诊为胎儿卵巢囊肿蒂扭转的超声检查资料,并随访新生儿出生后情况。结果6例胎儿卵巢囊肿蒂扭转均经产前超声检出,2例首次超声表现为单纯型囊肿,囊壁薄,可见囊中子囊结构;4例表现为复杂型囊肿,囊壁均较厚,其中2例呈实性为主混合回声,2例呈粗大网状分隔或混杂沉积物实性回声;6例囊壁及囊肿内部均无血供。分娩前复查超声均表现为复杂型囊肿,其中1例呈囊性为主混合回声,可见“液平”改变,2例呈实性为主混合回声,3例呈实性回声,内部及囊壁可见钙化;6例囊壁及囊肿内部均无血供;5例最大径>4.0 cm,1例最大径<4.0 cm。出生后2例新生儿行卵巢囊肿剥除术,3例行扭转侧卵巢切除,术中扭转角度360°~1080°;1例发生卵巢自截。结论产前超声可准确诊断胎儿卵巢囊肿蒂扭转,具有重要的临床价值。

Objective To investigate the clinical value of prenatal ultrasound in the diagnosis of fetal ovarian cyst torsion.Methods The ultrasonic data of 6 cases of fetal ovarian cyst torsion diagnosed after delivery in our hospital were retrospectively analyzed,the condition of newborns after birth were follow-up.Results There were 6 cases of fetal ovarian cyst torsion detected by prenatal ultrasound.The first ultrasonic manifestations of 2 cases showed simple cyst with thin wall and the sub cyst in the cyst structure.The other 4 cases showed complex type cysts with thick wall,of which 2 cases were mainly solid mixed echo,and 2 cases were solid echo with thick reticular separation or mixed sediment.There was no blood supply in the wall and interior of the cyst in 6 cases.All 6 cases showed complex cysts before delivery,of which 1 case showed mainly cystic with typical“liquid level”change,2 cases showed mainly solid mixed ehco,3 cases showed solid with calcificationthe interior and cyst wall.There was no blood supply in the wall and interior of the cyst in 6 cases.The maximum diameter in 5 cases were larger than 4.0 cm and 1 case was less than 4.0 cm.2 newborns underwent ovarian cyst removal,3 newborns underwent torsion side ovariectomy,the intraoperative torsion angle ranged from 360°to 1080°.1 newborn had ovarian autotomy.Conclusion Prenatal ultrasound can accurately diagnose the fetal ovarian cyst torsion,which has important clinical value.
