 Indra-abdominal umbilical vein varicose, varicose dilation of umbilical vein is a rare situation that makes up about 4% of all umbilical cord malformations and in the literature to date only around 100 cases have been reported. The types of varics have been classified according to the location. The most commonly observed are the extra-abdominal, the second type being indra-abdominal of which intrahepatic ones are the rarest. We here report two cases. One had the rare form of indra-abdominal, indra-hepatic umbilical vein varicose and this was associated with disc genesis of corpus callus. Another case of indra-abdominal extra-hepatic umbilical vein varicose was seen. A 38-year-old G1P0 patient came directly for a normally scan. The first time this scan was not performed. Term size was delivered. No clinical features of trisomy 21 were noted in pregnancy. On gray scale, focal dilation of the indra-hepatic umbilical vein was seen measuring approximately 36 by 42 mm. Color and par Doppler showed continuous venous flow with turbulence. The right and left portal branches and ductus venousus showed normal flow and no apparent thrombosis was seen. Antinatally, thinned-out genu and anterior body of corpus callusum was seen with non-visualization of the plenium, suggestive of partial A genesis of corpus callusum. This was associated with mild colpochipli and irregular contour of the lateral ventricle. The perichelusal artery was seen following the anterior part of the corpus callusum but its normal course in the posterior part was lost. At the level of plenium, the artery moved in an upward and posterior oblique direction. On postnatal dates, we follow up. Near to complete thrombus of the umbilical vein barrage was seen. A small thrombus was also seen in the left and main portal vein, partially occluding the lumen. Based on these findings, patient was started on LMWH. Postnatal dates 15 revealed consistent findings. However, this plenium of corpus callusum was seen on NFA, which appeared thinned-out, ruling out partial A genesis. And antinatal findings of this plastic genu and body of corpus callusum were confirmed. And this was finally suggestive of this plastic corpus callusum. Follow-up scan done on postnatal dates we 30 outside, revealed total recanalization of the previously thinned total vein thrombus. Case number 2, a 28-year-old G1P0 patient came for a normally scan. The first time this scan was non-performed. The patient had no history of diabetes, hypertension, asthma or thyroid disorder. No markers for aneuploidy were present. Patient has 35 weeks zero days gestational age at present, not yet developed. Grayscale and color Doppler immense show in extra-hypatic intra-abdominal umbilical vein varic, which was seen just superior to the urinary bladder. Follow-up scan done after 5 weeks, revealed no significant interval change, no obvious thrombosis was seen and the ductal phenosis shown normal cellophilus. Anatomy. The umbilical vein enters the fetal abdomen within the faulty form ligament and ascends deeply towards the liver along its inferior surface. The umbilical vein then joins a confluence of vessels turned the portal sinus. The portal sinus is a vascular space and is a conglomeration of structures including the intra-hypatic portal vein which is made up of the left and the right portal veins. The extra-hypatic portal vein comprising the splenic and superior mesentery vein and the ductal phenosis. The ductal phenosis originates from the superior aspect of the portal sinus, it then bypasses the liver and churns blood into the heart of the fetus directly. After birth, umbilical vein and ductal phenosis regress. This is the cross-sectional image of the fetal abdomen at the level of liver showing the anatomy of umbilical vein and portal sinus. The diagnostic criteria are as follows. The diameter of umbilical vein increases linearly with gestational age and the diagnosis is made when the diameter is more than 2 standard deviations. Other diet areas include umbilical vein diameter more than 9 mm at term gestation, umbilical vein diameter more than 50% of its non-dilated portion and umbilical vein diameter more than 1.5 times its intra-hypatic portion. The clinical impact depends on the gestational age and detection with the varices detected before 26 weeks carrying a word synosis. The complications include aneurysm rupture, thrombosis, heart failure and compression of the umbilical artery or the neighboring structure. A meta-analysis of 218 cases was conducted and the results were as follows. Around 170 cases had normal outcomes. Obstetric complications were seen in 42 cases of which 15 had oligo-hydroaminase, 8 had the spacial diabetes mellitus, 4 had IUGR, 3 patients of pre-eclampsia vaccine, placenta previa, 3-dom delivery and polyhydroaminase were seen in 2 cases each. Major malformations were observed in 17 cases of which the urogen ideal system was involved in 4 cases. Isolated cardiac defects were seen in 3 cases and hydroxpitalis and non-illusional skeletal dysplasia were seen in 2 cases each. Minor ultrasound abnormalities were noted in 17 cases of which the most common were TNL which was involved in 3 cases. Bilateral mild moderate phylectasis, cryptorchidism and single umbilical artery were seen in 2 cases each. Promosomal abnormalities were seen in 6 cases of which 5 had trizomus 21. Intrauterine demise were seen in 7 cases. The results of the meta-analysis are as follows. Detection of FIU calls for careful screening. Monitoring for growth is required. In the absence of malformations, usually the prognosis is favorable and fetal carotide being needs to be offered only if there are other abnormalities observed on ultrasound. Take-home message. This plastic corpus callus was a normal finding that has not been reported seriously. Weight and watch quality should be adopted. Continuous thrombosis has also been documented previously and closed monitoring is advisable before any urgent interventional management. And LNWH proved to be an excellent treatment option for thrombolitis of umbilical vein varicose. These are my references. Thank you.
