Prenatal diagnosis of aorta-portal vein-umbilical vein anastomosis

Prenatal Diagnosis of Aorta-Porto-Umbilical Vein Fistulas with Left-Sided Inferior Vena Cava.

Congenital arteriovenous fistulas involved with the abdominal aorta are very rare. Left-sided subrenal inferior vena cava (IVC) with normal connection to the heart is also rare and has not been reported prenatally. In this article, we described a fetus with aorta-porto-umbilical vein fistulas combined with a left-sided IVC.

Prevalence of Portal Vein Thrombosis Following Umbilical Catheterization in Neonatal Period

Introduction Group B streptococcus is the main reason of neonatal infection in developed countries and causes a widespread clinical indications. In developing countries such as Iran, its rate of appearance is not determined. With regard to colonization and the relative high epithelia of group B streptococcus, it is likely that the incidence of group B streptococcus in neonatal sepsis is so high...

The Prevalence of Portal Vein Thrombosis in Children under 3 Years Old with History of Neonatal Umbilical Vein Catheterization in the Neonatal Intensive Care Unit

Background Portal vein thrombosis (PVT) is one of the most common causes of extrahepatic portal hypertension in children, which may follow neonatal umbilical vein catheterization. The incidence rates of catheter-related PVT, in infants and children vary in different studies. This study aimed to determine PVT incidence in the children under 3 years old with a history of neonatal umbilical vein c...

Radiological Diagnosis of Portal/Mesenteric Vein Occlusion

BACKGROUND In contrast to an acute occlusion of the visceral arteries, which is the most important differential diagnosis for an occlusion of the portal venous system and which poses a highly dangerous situation ending in gangrene of the bowel wall, the symptoms of an acute occlusion of the portal venous system are quite unspecific. To rule out an acute arterial occlusion, diagnostic evaluation...
