| 目的 观察胎儿高位空肠闭锁的超声表现。方法 回顾性分析经出生后手术确诊高位空肠闭锁的32胎胎儿资料，观察其特征性超声表现，评价产前超声所测增宽肠管的长度与生后术中测量空肠闭锁部位至屈氏（Treitz）韧带之间肠管长度的关系。结果 产前超声中，32胎多见增宽肠管呈"C"型分布，且末端均超过脊柱左缘，孕晚期增宽肠管长度均大于胃泡长度；21胎于孕28周前、11胎于孕28周及之后检出异常；31胎肠管增宽或呈"双泡征"，1胎于孕21+3周见腹腔钙化灶，无肠管增宽及腹腔积液；25胎增宽肠管与胃泡相通、7胎不相通；28胎增宽肠管长度及内径均随孕周而增加，2胎仅见增宽肠管内径增加，2胎内径减小。孕晚期产前超声所测增宽肠管的长度（Y）与术中测量的闭锁部位至屈氏韧带之间的肠管长度（X）呈线性正相关，回归方程为Y=0.33X+86.43（F=7.719，R2=0.36，P<0.05）。结论 高位空肠闭锁胎儿超声多见增宽肠管呈"C"型分布并与胃泡相通，其末端超过脊柱左缘；结合超声测量增宽肠管的长度有助于诊断。 |

| Objective To observe the ultrasonic manifestations of fetal high jejunal atresia. Methods Data of 32 fetuses with high jejunal atresia confirmed by surgery after birth were retrospectively analyzed, and the ultrasonic manifestations were observed. The relationship of the dilated intestinal length on prenatal ultrasound and the intestinal length between jejunal atresia and Treitz ligament measured during surgery was analyzed. Results Prenatal ultrasound showed that the dilated intestine tended to distribute as "C" shape, and the distal end passed the left edge of spine, with the length greater than that of gastric vesicle measured in the third trimester. Among 32 fetuses, the abnormalities were detected before 28 weeks of gestation in 21 fetuses but at and after 28 weeks of gestation in 11 fetuses. The intestine dilated or presented as "double bubble sign" in 31 fetuses, while abdominal calcification was found at 21+3 weeks of gestation without dilated intestine nor peritoneal effusion in 1 fetus. The dilated intestine were connected with gastric vesicle in 25 fetuses, while were not connected with gastric vesicle in 7 fetuses. The length and inner diameter of dilated intestine increased with gestational weeks in 28 fetuses, while the inner diameter of dilated intestine increased in 2 fetuses and decreased in 2 fetuses. There was a linear positive correlation of the length of dilated intestinal on prenatal ultrasound (Y) and the intestinal length between jejunal atresia and Treitz ligament measured during surgery (X), and the regression equation was Y=0.33X+86.43 (F=7.719, R2=0.36, P<0.05). Conclusion Fetal high jejunal atresia mostly manifested as dilated intestine with "C" shape distribution and connected with the gastric vesicle, and the distal end passed the left edge of spine. |
