An attempt was made to identify all patients diagnosed as having deep vein thrombosis (DVT) in a large teaching hospital during one year. A review of the radiology records showed that 124 (81%) of the 154 venograms performed were for suspected DVT, and that the diagnosis was confirmed in 57 (46%). During the same period, the Hospital Activity Analysis (HAA) records revealed 174 episodes classif...

Metrizamide is largely replacing iophendylate (Pantopaque) for routine lumbar myelography. Better visualization of the nerve root sheaths should make metrizamide myelography more sensitive in detecting laterally herniated disks, such that epidural venography might be required less often. However, that expectation has not been realized. In over 800 consecutive myelograms, one-half obtained with ...

Cerebral venous thrombosis is a relatively uncommon but serious neurologic disorder that is potentially reversible with prompt diagnosis and appropriate medical care. Because the possible causal factors and clinical manifestations of this disorder are many and varied, imaging plays a primary role in the diagnosis. Magnetic resonance (MR) imaging, un-enhanced computed tomography (CT), unenhanced...

Recurrent venous thrombosis presents a diagnostic challenge. Venography, impedance plethysmography and fibrinogen leg scanning all have potential limitations, and their role in this context has not been evaluated. We performed a prospective cohort study evaluating impedance plethysmography and leg scanning, plus venography, using outcome on long-term follow-up as the end point in 270 patients w...

BACKGROUND Sclerotherapy with polidocanol microfoam injection under duplex guidance is a new treatment for venous malformations associated with Klippel-Trenaunay syndrome. Multidetector-row computed tomography (MDCT) venography is extremely helpful in the assessment of disease extension and the planning of therapy. Observation In this particular case, MDCT venography demonstrated the origin, co...

BACKGROUND There have been sporadic reports on the Asian risk factor of DVT after total knee arthroplasty. OBJECTIVE To determine the risk factors of DVT MATERIAL AND METHOD: Retrospective review of one hundred patients who had undergone TKA and postoperative Contrast Venography in bilateral legs between 2002 and 2005 were performed to identify risk factor of DVT The patients were divided int...

Systemic venous collaterals may cause an inordinate amount of hypoxemia or unsustainable oxygen requirement after single ventricle palliation with a superior cavopulmonary anastomosis. Anterior are easily identified by injections contrast in the vena cava innominate vein during heart catheterization (venography), while posterior be overlooked. This report describes how well systemic were venogr...

Intrahepatic venous collaterals develop in Budd-Chiari syndrome, hepatomas, and other tumors if the hepatic veins are obstructed. In portal hypertension hepatic vein-to-vein anastomoses develop without obstruction of the hepatic veins. In a 53-year-old woman with giant cavernous hemangioma of the liver, hepatic venography demonstrated remarkable hepatic vein-to-vein anastomoses in the periphery...

Although it is generally accepted that negative venography excludes deep vein thrombosis (DVT) in patients in whom it is clinically suspected, there is no evidence to support this conclusion. To test the correctness of withholding anticoagulant therapy in these patients, we followed 160 consecutive patients who had clinically suspected DVT and negative venograms to determine the frequency of po...

Varicose veins in the vulvar and peri-vulvar area are seen in 4% of women and most commonly seen during pregnancy. It is thought to be as a direct result of the presence of ovarian and pelvic varicosities. Diagnostic modalities used in the investigation of this condition included pelvic ultrasound, computed venography, magnetic resonance venography and catheter-directed venography. The treatmen...
