The patient was a 76 year old woman. Three weeks before she was hospitalized with diagnosis of intracerebral hemorrhage due to motor vehicle accident. During hospital course the patient developed deep vein thrombosis so she was consulted for Inferior Vena Cava (IVC) filter implantation. 10 days before an IVC filter (Optease, Cordis, Miamai) was implanted in IVC. IVC venography before implantati...

Two cases of recurrent pulmonary emboli secondary to thrombosis in anomalies of the deep veins of the lower limb are presented. In both cases the source of emboli was not evident clinically, and it was only after venography that the venous anomalies were discovered, both being confined to one limb and amenable to surgical intervention. Such anomalies have not previously been reported as sources...

New technologies have produced a revolution in primary varicose vein treatments. Duplex ultrasound is now used for preoperative diagnosis, postoperative surveillance, and during many procedures. Ultrasound has also altered our understanding of the pathophysiology of chronic venous disease. Laser and radiofrequency saphenous ablations are common. Classic techniques, such as sclerotherapy, high l...

We randomised 250 patients undergoing unilateral, elective hip arthroplasty for osteoarthritis to receive either a cemented or a non-cemented Mallory Head prosthesis. Aspirin was used as prophylaxis against thromboembolism during the first half of the study and adjusted-dose warfarin during the second half. Postoperatively, all patients were asked to have bilateral venography and 80% agreed. Al...

The diagnosis of venous thromboembolism on the basis of clinical signs and symptoms is notoriously inaccurate and, therefore, mandates confirmatory diagnostic testing. Unfortunately, all diagnostic tests for deep venous thrombosis (DVT) and pulmonary embolism have clinical or practical limitations. Contrast venography and pulmonary arteriography are usually regarded as the reference standards f...

BACKGROUND AND PURPOSE The distribution of multiple sclerosis (MS) lesions in the brain follows a specific pattern, with most lesions in the periventricular regions and in the deep white matter; histopathologic studies have shown a perivenous distribution. The aim of this study was to illustrate these distribution patterns in vivo using high-resolution MR venography. METHODS Seventeen MS pati...

Digital subtraction angiography was traditionally considered the best modality for diagnosing CVT. The procedure's invasive nature, however, coupled with an associated risk of cerebrovascular complications, has led to its increasing replacement by MR imaging, and especially MR venography.2 But MR has a number of its own drawbacks. Several studies have reported limited accuracy of MR venography ...
