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 cau...

During a routine cadaver dissection, we have encountered an anomalous formation of inferior vena cava and abnormal channels communicating the two internal iliac veins with the inferior vena cava in a 67 year old male cadaver. The said channels which had a caliber of 5 mm on the left side and 15 mm on the right arose at a distance of 26 mm on the left and 35 mm on the right from the internal ili...

A case of postoperative pulmonary artery catheterisation complicated by knotting of the catheter (Swan-Ganz) within the superior vena cava is described. The catheter was cut off at the skin entry site. The remainder, together with the knot, was pulled out through a purse string incision in the superior vena cava.

Persistence of the left superior vena cava occurs in about 0.3-0.7% of the general population. It is of particular importance in patients who need cardiac resynchronisation therapy. We present a unique case in which a snare system and tunnelling tool were used to place the left ventricular lead in a patient with persistence of the left superior vena cava.

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.

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...

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...

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...
