A 38-year-old male was initially admitted for left leg swelling. He was diagnosed as having deep vein thrombosis (DVT) in the left leg and a pulmonary thromboembolism by contrast-enhanced chest computed tomography (CT) with delayed lower extremity CT. The DVT was treated by thrombolysis and a venous stent. Four hours ...

Deep vein thrombosis - the formation of clots in one of the body's deep veins (usually in the lower extremities) - develops as a result of vascular damage to the vein wall, venous stasis, and hypercoagulability (Virchow's triad). Among the many problems it can cause, the condition can escalate the ...

Over a 13-year period we studied all patients who underwent major hip and knee surgery and were diagnosed with objectively confirmed symptomatic venous thromboembolism, either deep venous thrombosis or non-fatal pulmonary embolism, within six months after surgery. Low-molecular-weight heparin had been given while the patients were in hospital. There were ...

Laser first emerged as a technology for use in the vascular arena nearly 20 years ago. The ability of laser to evaporate atherosclerotic plaque was extensively studied; however, the goal of creation of an adequate channel without arterial wall perforation proved to be elusive, and the technique fell into disfavor. ...

We report two cases of femoral vein thrombosis after arterial PTA and subsequent pressure stasis. We discuss the legal consequences of these complications for information policies. Because venous thrombembolism following an arterial PTA might cause serious sequel or life threatening complications, there is a clear obligation for explicit information of ...

Paget-Schroetter syndrome or effort-related upper extremity deep vein thrombosis is a rare condition that usually afflicts young healthy individuals, most commonly males. The cause is multifactorial but almost always involves extrinsic compression of the subclavian vein at the thoracic inlet, causing venous stenosis from repetitive trauma. The diagnosis of this ...

The standard diagnostic approach of suspected deep vein thrombosis (DVT) is serial lower limb compression ultrasound (CUS) of proximal veins. Although it only assesses the proximal veins, withholding anticoagulant treatment in patients with a negative CUS on day one and after one week has been proven to be safe. However, ...

Behçet disease (BD) is a chronic relapsing systemic vasculitic disorder affecting the arteries, veins, and vessels of any size. Vascular lesions in BD usually represent an occlusive nature suggesting a hypercoagulable/ prothrombotic state. Coronary arteries are rarely involved in BD. In this report, a 27-year-old male patient in whom myocardial ...

The D-dimer analysis has been shown to have a high sensitivity and a high negative predictive value for the exclusion of deep vein thrombosis (DVT). However, most D-dimer studies, including recent clinical management studies, are performed without examination of the calf veins and/or performed on patient populations with a predominance ...

BACKGROUND: Annually, 2 million people in the United States develop deep venous thrombosis (DVT), and nearly 100,000 sustain fatal pulmonary emboli. Prophylaxis against DVT/pulmonary embolism (PE) is a critical issue, and options include elastic stockings, intermittent pneumatic compression stockings, low-dose unfractionated heparin (5000 U every 8-12 hours), and low molecular-weight ...

Deep venous thrombosis (DVT) is a serious illness sometimes causing death due to acute pulmonary thromboembolism (PTE). Blood stasis of the pelvic vein is a major etiologic factor for DVT. Occasionally a large myomatous uterus can cause compression of the pelvic venous system leading to DVT. We describe a very ...

INTRODUCTION: In patients with new symptoms in a leg previously affected by deep vein thrombosis (DVT), the presence of thrombus on ultrasound cannot be assumed to be due to recurrent thrombosis. Several parameters have been suggested to differentiate between acute and chronic thrombus on ultrasound, including measurement of residual vein ...

Duplex ultrasound is the most useful examination for the evaluation of venous valvular incompetence. Multi-frequency 4 to 7-MHz linear array transducers are typically used for this assessment of superficial and deep reflux. The examination is done with the patient standing and manual compression maneuvers are used to initiate reflux. Automatic ...

Chronic venous insufficiency (CVI) is a pathologic condition caused by valvular incompetence, with or without associated venous outflow obstruction, which may affect both the superficial and the deep venous system, causing venous hypertension and stasis. The most common form of CVI is primary varicose veins due to the insufficiency of ...
