Abstract Objective To study the course of a superior mesenteric artery (SMA) and the angle between SMA and abdominal aorta in early pregnancy, and to explore its significance in early diagnosis of fetal abdominal structural abnormalities. Methods 50 cases of pregnant women with NT color Doppler ultrasound in our hospital and confirmed by delivery or induced labor were selected. The fetal morphology and the course of the fetal superior mesenteric artery were observed, and the angle between the superior mesenteric artery and the abdominal aorta was measured. Results 45 cases of the normal fetus and 5 cases of the abnormal abdomen were confirmed in pregnant women (1 case was missed in early pregnancy). The abnormal course of superior mesenteric artery was found in 4 cases, and the angle between the superior mesenteric artery and the abdominal aorta was abnormal in 4 cases. Conclusion The abnormal course of a superior mesenteric artery or abnormal angle between superior mesenteric artery and abdominal aorta in early pregnancy can be found by using color Doppler low-speed HD-Flow examination, which has definite significance for early diagnosis of fetal abdominal abnormalities such as abdominal fissure, omphalocele, diaphragmatic hernia,and abdominal mass.
