OBJECTIVE To evaluate the role of CT venography in the diagnosis and treatment of benign thoracic central venous obstruction. MATERIALS AND METHODS Eighteen patients who had undergone both CT venography and digital subtraction venography were prospectively enrolled in this study. The following features were analyzed by two observers: the cause, degree, and extent of venous obstruction; associ...

AIMS The number of implantable cardioverter defibrillator (ICD) implantations, as well as follow-up procedures such as generator exchanges, lead revisions and lead system upgrades, is ever-increasing. Lead revisions and implantation of additional leads require venous access at the site of the previous ICD implantation. The aim of our study was therefore to evaluate the incidence of venous obstr...

We have evaluated the degree to which hepatic arterial infusion of Adriamycin produces higher hepatic and lower systemic drug concentrations than are achieved with corre sponding peripheral venous infusion. Hepatic arterial catheters were placed in seven patients with primary or metastatic liver cancer. Temporary hepatic venous catheter placement allowed direct sampling of drug levels in the he...

Superior vena cava obstruction is associated with multiple venous collaterals. There is an unusual pathway involving pulmonary venous collaterals in which systemic veins drain directly into the left heart, resulting in a right-to-left shunt. We report here a rare case of systemic to pulmonary venous shunt on both hemithoraces in superior vena cava obstruction associated with Budd-Chiari syndrom...

The invasive measurement of the hepatic venous pressure gradient is still considered as reference method to assess severity portal hypertension. Even though previous studies have shown that liver stiffness measured by elastography could predict hypertension in patients with chronic disease, mechanisms behind remain today poorly understood. main reason not specific and also influenced concomitan...

OBJECTIVES Our aim was to compare retrospectively hepatic venous and delayed phase images for the detection of tumour washout during multiphasic multidetector row CT (MDCT) of the liver in patients with hepatocellular carcinoma (HCC). METHODS 30 cirrhotic patients underwent multiphasic MDCT in the 90 days before liver transplantation. MDCT was performed before contrast medium administration a...

The value of colour Doppler sonography is well known in the assessment of venous disease, including obstruction/occlusion from thrombosis. Central venous disease, however, can be more difficult to directly assess than disease in peripheral veins. Accordingly, there is significant value not only in the direct signs of venous disease, but also in the indirect signs. We report a case of reversed i...

To evaluate the efficacy of chest roentgenograms and echocardiograms in identifying pulmonary venous pathway obstruction in patients after the modified Fontan procedure, the records of 297 patients who underwent 307 Fontan procedures between 1984 and 1990 were reviewed. Twelve cases of pulmonary venous pathway obstruction documented by autopsy (3 cases) or cardiac catheterization (9 cases with ...

Secondary chronic venous disorders (CVD) usually follow an episode of acute deep venous thrombosis (DVT). Most occluded venous segments recanalize over the first 6 to 12 months after an episode of acute DVT, leading to chronic luminal changes and a combination of partial obstruction and reflux. Such morphological changes produce venous hypertension with the highest levels of ambulatory venous p...
