Abstract：
Fetal thoracoamniotic shunting (TAS), which drains pleural effusion, is a treatment for severe primary fetal pleural effusion. While TAS is an effective treatment, its complications include bleeding and the catheter becoming dislodged, and also penetrating the thoracic cavity or chest wall. Catheters dislodged into the thoracic cavity in TAS can be removed by thoracoscopy. However, if there are adhesions in the thoracic cavity, finding the TAS catheter with a thoracoscope can be difficult. We used fluoroscopic radiography in addition to a thoracoscope to remove a TAS catheter in four patients. A 5-mm trocar was inserted into the thoracic cavity, and a 2.7-mm scope and 3-mm forceps were inserted into the trocar. We searched for TAS catheters using a thoracoscope and fluoroscopic radiography. If there are adhesions in the thoracic cavity and removing the TAS catheter is difficult, the combined use of a thoracoscope and fluoroscopic radiography may prove helpful.
摘要：
胎儿胸羊膜分流术（TAS），引流胸腔积液，是严重的原发性胎儿胸腔积液的治疗方法。虽然TAS是一种有效的治疗方法，它的并发症包括出血和导管移位，并穿透胸腔或胸壁。可以通过胸腔镜将TAS中移位到胸腔中的导管移除。然而,如果胸腔有粘连,用胸腔镜找到TAS导管可能很困难。除胸腔镜外，我们还使用了透视X线照相术，以移除四名患者的TAS导管。一个5毫米的套管针插入胸腔，并将2.7毫米的范围和3毫米的镊子插入套管针。我们使用胸腔镜和荧光透视检查来搜索TAS导管。如果胸腔有粘连，并且很难取出TAS导管，结合使用胸腔镜和透视X线照相术可能会有所帮助。
