Isolated rupture of the infrarenal segment of the inferior vena cava due to blunt trauma is relatively rare. It may be missed clinically and even diagnostic peritoneal lavage may prove negative. The mainstay of diagnosis remains a high degree of clinical suspicion together with sectional imaging. If the patient is haemodynamically stable after initial resuscitation and there is no other indicat...

Background: Inferior vena cava filter complications can range from dislodgement to perforation. Patients who present with concomitant bacteremia have rarely been reported. Persistent bacteremia usually results from direct bacterial seeding from a source other than perforation of surrounding viscus. It is unclear if the risk of perforation is higher in patients who are bacteremic due to other ca...

OBJECTIVE To evaluate the occurrence of pulmonary arteriovenous malformations after a Fontan operation in the left isomerism and absent inferior vena cava. METHODS We retrospectively reviewed 19 patients with the left isomerism and absent inferior vena cava who underwent Fontan operations at our institution. We divided the patients into two groups: bilateral superior vena cava (group A, n=9),...

BACKGROUND The purpose of this study was to evaluate the results of hepatectomy with inferior vena cava or hepatic vein resection, followed by vessel reconstruction with an artificial vascular graft. METHODS From 2000 to 2011, 1,434 patients underwent several types of hepatectomy at our institution. Of these, we reviewed the cases of eight patients (0.56%) who underwent hepatectomy with infer...

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 tun...

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...
