In 16 chronically prepared fetal lambs we compared the systemic distribution of ductus venosus blood flow with that of abdominal inferior vena caval blood by simultaneously injecting microspheres labeled with different radionuclides into an umbilical vein and into the abdominal inferior vena cava. A significantly greater proportion of ductus venosus blood flow than of abdominal inferior vena ca...

BACKGROUND AND AIMS Installing the transjugular intrahepatic portosystemic shunt for portal hypertension is relatively safe, but complications are still high. To explore a new method of portacaval shunt, the magnetic compression technique was introduced into the shunting procedure. METHODS A portal-inferior vena cava shunt was performed on 6 male mongrel dogs by two hemocompatible Nd-Fe-B per...

Primary tumors of the heart, pericardium and inferior vena cava are extremely rare. Three cases of surgically/biopsy proven angiosarcoma of the right atrium, pericardial lipoma and leiomyosarcoma of inferior vena cava--demonstrated by ultrasound, computed tomography (CT) and magnetic resonance imaging (MRI)--are presented here.

Venous thromboembolism is common. Most pulmonary emboli arise as thromboses in the deep veins of the lower extremities and may result in serious complications. Inferior vena cava filters (IVCF) are intended to prevent the passage of deep vein thrombosis to the pulmonary arteries. Accepted indications for IVCF placement include the presence of acute venous thromboembolism with inability to admin...

Thrombosis of the inferior vena cava (IVC) is an under-recognized entity that is associated with significant short- and long-term morbidity and mortality. In absence of a congenital anomaly, the most common cause of IVC thrombosis is the presence of an unretrieved IVC filter. Due to the substantial increase in the number of IVC filters placed in the United States and the very low filter retriev...

Background Testing for the susceptibility of vasodepressor reaction in humans involves the combination of restriction of venous return by passive upright tilting and the administration of isoproterenol. We developed an experimental rat model in which vasodepressor reactions are induced when the inferior vena cava is occluded during an infusion of isoproterenol. The reactions are characterized b...

Psoas abscess is a rare clinical entity. Rarely, it is associated with thrombosis of the inferior vena cava. This report is of a 36-year-old woman with bilateral pyogenic psoas abscesses with spondylodiscitis complicated by thrombosis of the inferior vena cava. The pathogenesis and imaging features of this condition are discussed.

Inferior vena cava anomaly is usually asymptomatic. It is rare and commonly detected while performing abdominal imaging for other clinical situations. The anomalies can mimic normal anatomical structures. Thus, the identification of the anomalies is important to avoid complication during abdominal procedures. We report two cases of inferior vena cava anomalies found during Computed Tomography s...

Objective: To measure caval and pulmonary flows at rest and immediately after exercise in patients with total cavopulmonary connection (TCPC). Design: An observational study using the patients as their own controls. Setting: Using a combination of magnetic resonance (MR) phase contrast techniques and an MR compatible bicycle ergometer, blood flow was measured in the superior vena cava, the tunn...
