脐动脉舒张期血流消失时胎儿生长发育及出生情况分析

目的：分析晚孕期脐动脉舒张期血流信号消失时胎儿生长发育和出生时情况。方法采用彩色超声诊断仪检测脐动脉血流信号,对比分析脐动脉血流正常与脐动脉舒张期血流消失时胎儿的生长发育指标和出生时Apgar评分。结果脐动脉舒张期血流消失的胎儿生长发育小于孕龄的发生率明显高于正常组,出生时宫内窘迫的发生率也明显高于正常组。结论晚孕期脐动脉舒张期血流消失提示胎儿宫内缺氧,胎儿生长发育相对缓慢。     

Imaging sonographic findings of in a case of proliferating trichilemmal tumor of a finger: A case report

Proliferating trichilemmal tumor (PTT) is a rare tumor that originates from the outer root sheath of a hair follicle. About 90% of PTTs occur on the scalp. The sonographic findings of PTT in the subungual region have not been reported previously. In our case, sonography showed a heterogeneous mass containing echogenic foci with no detectable intratumoral vascularity. These echogenic foci probably represent keratin and cholesterol. © 2017 Wiley Periodicals, Inc. J Clin Ultrasound 46 :215–217, 2018     

Treatment of heterotopic caesarean scar pregnancy complicated with post termination increase in size of residual mass and morbidly adherent placenta

We report a case of a secundipara with heterotopic cesarean scar pregnancy (HCSP) treated with potassium chloride injection into the ectopic embryo followed by sac aspiration. The remaining “mass” increased in size threefold and was surrounded by a rich vascular network. An arteriovenous malformation was suspected; however, appropriate treatment was precluded because of the viability of the ectopic gestation. Sonographic examination revealed a morbidly adherent placenta, and attempt to resect the mass laparoscopically was complicated by bleeding that required hysterectomy. This case illustrates a complication of the intervention performed to preserve the intrauterine gestation in case of HCSP. © 2017 Wiley Periodicals, Inc. J Clin Ultrasound 46 :227–230, 2018     

Perinatal diagnosis and management of oropharyngeal fetus in fetu: A case report

Fetus in fetu is an extremely rare congenital anomaly. We describe the perinatal diagnosis and management of a fetus with oropharyngeal and cervical fetus in fetu. High‐resolution ultrasonography with 3‐dimensional rendering can identify increased risks of airway obstruction in utero. Early identification allows a multidisciplinary team to be assembled for a scheduled ex utero intrapartum treatment procedure.
