Venous thromboembolism (VTE) is a significant cause of morbidity and mortality worldwide. Anticoagulation is the preferred treatment for VTE, however, in selected patient populations, the risk of bleeding from anticoagulation outweighs its benefit. For these patients, alternative methods of pulmonary embolism (PE) prevention are needed. In 1865, Armand Trousseau proposed ...

BACKGROUND: We hypothesized that detection of reverse flow in the distal right coronary artery (d-RCA) and the inferior septal branches (ISB) by transthoracic Doppler echocardiography (TTDE) would be useful for noninvasive diagnosis of the occluded right coronary artery (RCA). METHODS: Coronary angiography and TTDE were performed on 129 patients. Antegrade ...

A persistent left superior vena cava draining into the left atrium may produce a symptomatic right-to-left shunt. Although intra-atrial rerouting techniques, in patients with no connecting vein, have proved to be reliable and successful, in many cases the extracardiac repair is preferable. We report a case of a 5-month-old patient ...

We describe a new employment of glutaraldehyde preserved autologous pericardium for patch reconstruction of the pulmonary artery (PA) and superior vena cava (SVC). This technique was devised to minimize technical problems related to the use of fresh pericardium such as excessive elasticity and tendency to curl. We have successfully employed ...

Formation of systemic to pulmonary venous or systemic venous left atrial collaterals frequently occurs in patients after Glenn or Fontan-type operations. Embolization with detachable metal coils is the therapy of choice for the closure of small vessels. These devices however are not appropriate for the occlusion of large collaterals, e. ...

Idiopathic aneurysms of the inferior caval vein are uncommon in children and adults. We describe a 14 year old boy with a saccular aneurysm of the inferior caval vein, in whom no surgical intervention was required to repair the aneurysm. The patient is being followed-up periodically for the evaluation of ...

BACKGROUND: We previously used the Fontan procedure, when applicable, by placing a temporary bypass from the inferior vena cava to the atrium. Alternatively, we have striven to achieve the procedure even without use of a temporary bypass in patients having collaterals between the inferior vena cava and the superior vena ...

Using ultrasound imaging, we investigated the roles of the potentially contractile veins and of the mantle (the powerful body wall that moves water over the gills, and also encloses the large veins and the hearts) in returning the blood of cuttlefish to its hearts. Ultrasound provided the first non-invasive observations ...

To reduce the possibility of cardiac tamponade, a rare but lethal complication of central venous catheters, the tip of the central venous catheter should be located above the cephalic limit of the pericardial reflection, not only above the superior vena cava-right atrium junction. This study was performed to measure the ...

A now 36-year-old woman developed a suprahepatic inferior vena cava stenosis, 9 years after liver transplantation for extensive liver echinococcosis. The lesion was treated by percutaneous angioplasty and stenting. Five years later, recurrence of echinococosis with intrastent stenosis together with clinical symptoms, prompted surgical treatment. Hepato-atrial anastomosis was performed under ...

Congenital anomalies of the inferior vena cava (IVC), such as absence or atresia, although well documented, are uncommon and result from aberrant development during embryogenesis. Absence or atresia of the IVC is usually discovered accidentally. Patients are typically asymptomatic of the condition itself. Many concurrent cardiovascular-associated abnormalities have been described. ...

In patients at risk for pulmonary emboli, consideration is often given to placement of an inferior vena cava (IVC) filter to prevent propagation of a distal thrombus. However, long-term benefits remain controversial, and deep venous thrombosis and IVC thrombosis may result from the procedure itself. Whether a filter if beneficial ...

Vena cava filters have been in use for decades to prevent pulmonary embolization from deep venous thrombosis. These filters have been shown to be effective, with fairly low rates of filter migration, fracture and thrombosis. However considering that filters remain in situ for the life of the patient and that ...

We report two cases of left superior vena cava draining directly to the left atrium in the absence of complex congenital heart disease. This is a rare finding causing a decrease in patient oxygen saturations. The location and diagnosis of this systemic venous anomaly requires diligence on the part of ...
Rosenthal David - - 2004
Patients with multiple trauma often have injuries that preclude the use of anticoagulation therapy or sequential compression device prophylaxis. Temporary inferior vena cava (IVC) filters (IVCFs) offer protection against pulmonary embolism during the early immediate injury and perioperative period, when risk is highest, while averting potential long-term sequelae of permanent ...
