Regarding the extrahepatic shunt, there are different possible connections between the umbilical vein and the venous system: (1) the umbilical vein shows direct connection to the right atrium (RA), left atrium or through a dilated coronary sinus (CS). We perform a systematic review of the literature comprising a 25-year period from 1992 to September 2017. 4. Modern techniques, particularly ultrasound associated with Doppler, have opened a new era of clinical evaluation of the fetus, namely in the first trimester. %PDF-1.1 All of this blood passes into circulation and is carried via umbilical arteries back to the placenta for oxygenation. Register now 1. This is achieved by unique features of blood vessels which help create differences in velocities and direction of blood flow. << No assumptions were made during the process of data collection and all collected variables were clearly stated in original reports. The connection to the iliac vein was first described in 1996 [10]; (5) the umbilical vein shows a direct connection into the renal vein; (6) the umbilical vein shows direct connection into the right ventricle.
