ACR Appropriateness Criteria® Radiologic Management of Iliofemoral Venous Thrombosis.

Iliofemoral venous thrombosis carries a high risk for pulmonary embolism, recurrent deep vein thrombosis, and post-thrombotic syndrome complicating 30% to 71% of those affected. The clinical scenarios in which iliofemoral venous thrombosis is managed may be diverse, presenting a challenge to identify optimum therapy tailored to each situation. Goals for management include preventing morbidity from venous occlusive disease, and morbidity and mortality from pulmonary embolism.

ACR Appropriateness Criteria Radiologic Management of Venous Thromboembolism-Inferior Vena Cava Filters.

Venous thromboembolism (VTE)-deep vein thrombosis and pulmonary embolism-is a common cause of morbidity and mortality. The mainstay of VTE prophylaxis and therapy is anticoagulation. In select patients with VTE, inferior vena cava (IVC) filters are used to prevent pulmonary embolism by trapping emboli as they pass from the lower extremity venous system through the IVC.

ACR Appropriateness Criteria Iliac Artery Occlusive Disease.

Iliac artery occlusive disease can present as a sudden-onset acute thrombotic or thromboembolic event or as a chronic progressive atherosclerotic process that presents as claudication progressing to rest pain. Depending on the clinical presentation, the diagnosis is usually confirmed through Doppler vascular ultrasound, CT angiography, or MR angiography; the choice of imaging is usually based on modality availability and the presence of patient comorbidities such as chronic kidney disease. The Trans-Atlantic Inter-Society Consensus II classification system is commonly used to describe the extent of the peripheral vascular disease.

ACR Appropriateness Criteria Radiologic Management of Central Venous Access.

Obtaining central venous access is one of the most commonly performed procedures in hospital settings. Multiple devices such as peripherally inserted central venous catheters, tunneled central venous catheters (eg, Hohn catheter, Hickman catheter, C. R.

ACR Appropriateness Criteria Chylothorax Treatment Planning.

Chylothorax is an uncommon but serious medical condition, which arises when intestinal lymphatic fluid leaks into the pleural space. Treatment strategies depend on the daily output and underlying etiology, which may be due to direct injury to lymphatic vessels or a nontraumatic disorder. Chest radiographs confirm the presence of pleural fluid and lateralize the process.

Percutaneous blunt dissection technique for retrieval of over-the-wire Greenfield filters.

Although the over-the-wire Greenfield filter was designed as a permanent filter, the present report describes two patients who had Greenfield filters percutaneously removed. One was removed at approximately 2,250 days after placement. This patient had developed severe abdominal pain believed to be caused by the filter that resolved after percutaneous filter removal.
