    Prenatal diagnosis of abnormality of the umbilical portal DV complex: difficulty in universal classification due to various alternative routes in hepatic circulation for placental drainag
    (2020) Demirci, Oya; Akay, Hatice Ozturkmen; 0000-0002-0854-0904; 33138669; AAD-8547-2021
    Objective To review our experience with fetal abnormality of the umbilical-portal-DV complex and to discuss the new classification system for umbilical portal systemic venous shunts (UPSVS) according to our cases. Methods This study was a retrospective analysis of fetuses with a prenatal diagnosis of abnormality of the umbilical-portal-DV complex. The integrity of the fetal umbilical-portal ductus venosus complex and the hepatic venous system were evaluated using two-dimensional color Doppler sonography. The origin of the shunt, the location of the drainage, and the presence or absence of intrahepatic portal venous system and DV were noted. Results 35 cases of abnormality of the umbilical-portal-DV complex were identified. Agenesis of ductus venous was detected in 33 of them. Based on the abnormality of the umbilical-portal-DV complex, we divided the cases into five groups. Group 1, ductus venosus agenesis with normal hepatic venous anatomy (n = 11); Group 2 downward displacement of the umbilical-portal-DV complex (n = 13); Group 3, umbilical-systemic shunt (n = 5); Group 4, intrahepatic portosystemic shunt (n = 4), Group 5, hepatic arteriovenous malformation (n = 2). Three different intrahepatic portosystemic shunt and one different downward displacement of the umbilical-portal-DV complex cases were detected. Conclusions Disruption of the normal anatomy of the umbilical-portal-DV complex causes various alternative pathway of the placental drainage. This illustrates highlights the challenge of creating a universal classification.

    Multi-center results on the clinical use of KANET
    (2019) Kurjak, Asim; Barisic, Lara Spalldi; Stanojevic, Milan; Antsaklis, Panagiotis; Panchal, Sonal; Honemeyer, Ulrich; Neto, Raul Moreira; Tinjic, Suada; Vladareanu, Radu; Esin, Sertac; Bomba-Opon, Dorota; Mededovic, Edin; Hata, Toshyuki; 31677378
    An extensive review of the literature on the diagnostic and clinical accuracy of Kurjak's antenatal neurodevelopmental test (KANET) and the summarized results of the multi-center study involving 10 centers revealed that four-dimensional ultrasonography (4D US) has become a powerful tool and KANET a valuable test that empowers the clinicians worldwide to evaluate the fetal behavior in a systematic way and contribute to the detection of fetuses that might be at high risk for neurological impairments and in particular cerebral palsy (CP). After 10 years of clinical use, many published papers and multi-center studies, hundreds of trained physicians and numerous tests performed all over the world, KANET has proven its value and has been showing encouraging results so far. The aim of this paper is to show the results from the studies done so far and to reveal the clinical value of the KANET. We expect that data from the larger ongoing collaborative study, the short- and long-term postnatal follow-up will continue to improve our knowledge. Ultimately, we all strive to prevent the CP disorders, autism spectrum disorder (ASD) and other neurological impairments and we are convinced that KANET might be helpful in the realization of this important aim.
