Deep vein thrombosis and pulmonary embolism are considered manifestations of the same pathophysiological process and are together referred to as venous thromboembolism (VTE). VTE is a common disorder with an incidence of 1 to 3 in 1000 in the general population. It is estimated that the incidence of VTE is likely to increase as the average life expectancy of the U.S. population increases. Treatment of VTE consists of anticoagulation; the duration of anticoagulation is largely determined by the circumstances surrounding development of the thrombotic event. Vitamin K antagonists, the only oral anticoagulants approved for treatment of VTE in the United States, have several drawbacks and therefore new oral anticoagulants are currently in various stages of development. This review focuses on the risk factors for VTE and the approach to determining the duration of anticoagulation in patients with VTE. Results of clinical trials on the new oral anticoagulants that may soon be licensed for the treatment of VTE are also discussed.

Over the past several years there has been a rapid increase in the number of inferior vena cava (IVC) filters placed for primary thromboprophylaxis. Increased use has occurred in settings where other methods of thromboprophylaxis are viewed to be inadequate, technically challenging, or that place patients at an unacceptably high bleeding risk. These clinical services include trauma, bariatric surgery, neurosurgery, cancer, intensive care unit populations, and patients with a relative contraindication to anticoagulation. We review the studies to date addressing filter placement for these indications. Although preliminary data are promising, the patient populations most likely to benefit from prophylactic IVC filter placement have not been well defined, and randomized studies demonstrating efficacy have not been conducted. Moving forward, it will be critical to accomplish these two tasks if IVC filters are to continue to have a role in primary thromboprophylaxis.

Inferior vena cava (IVC) filter thrombosis is a complex problem. Thrombus within an IVC filter may range from an asymptomatic small thrombus to critical IVC occlusion that affects both lower extremities. The published experience of IVC thrombosis management in relation to filters is either anecdotal or limited to a small group of patients; however, endovascular treatment methods appear to be safe and effective in patients with IVC thrombosis. This review focuses on filter-related IVC thrombosis and its endovascular management. Semin intervent Radiol 2012; 29(01): 057-063 DOI: 10.1055/s-0032-1302453.

We present the case of a five-year-old boy with a caroticoazygous fistula, which is an extremely rare congenital vascular malformation. The patient also had patent ductus arteriosus, a common cause of continuous murmur. The murmur continued despite successful coil embolization of the ductus. Repeated catheter-angiography revealed a large caroticoazygous fistula. The fistula was successfully embolized using the Amplatzer® Vascular Plug 1. Transcatheter occlusion of caroticoazygous fistula was performed easily, safely, and efficiently with a vascular plug. Diagn Interv Radiol 2012; 18:431–434.

A simple, precise, and consistent anatomical terminology is necessary for evaluating and treating patients with varicose veins. A clear understanding of the anatomy is also very important to correctly diagnose and perform the best treatment for varicose veins. Because the anatomy depicted by ultrasonography has many variations, anatomic definition for at least some of the veins still require clarification. Studies focusing on different segments of the veins are needed to obtain detailed anatomical knowledge given this great variability.
