case_images: She had a routine obstetrical ultrasound at 21 weeks gestation, which revealed an abnormal bean-like dilation of the intra-abdominal umbilical vein, and umbilical vein thrombosis was suspected (Figure 1).

case_images: On the second day of life, a second abdominal ultrasound confirmed the presence of a thrombus of 26 x 16 mm in umbilical vein thrombosis and a thrombus of 21 x 5 mm in portal vein (Figure 3).

case_images: This suggested that anticoagulant therapy was effective, and the dose of enoxaparin was gradually adjusted to 2.1 mg/kg twice a day to achieve the target anti-Xa level (Figure 4).
case_images: Ultrasound images of the patients ont day 16 of life (E) reduction in the size of the portal vein thrombus at day 16; (F) the blood flow signal of portal vein thrombosis at day 16; (G) reduction in the size of the umbilical vein thrombus at day 16; (H) the blood flow signal of umbilical vein thrombosis at day 16.

case_images: At day 16 of life, a fourth ultrasound showed that the thrombus was significantly smaller than before, and the stenosis degree of the portal vein decreased from 75 to 30% (Figure 5).
case_images: Ultrasound images of the patients on day 26 of life (I) Complete regression of the umbilical vein thrombus at day 26; (J) Complete regression of the portal vein thrombus at day 26; (K) normal blood flow signal of portal vein.
