Superior vena caval placement of a temporary filter: a case report.

Placement of permanent filters in the superior vena cava (SVC) for preventing pulmonary embolism (PE) arising from thrombi superior to the right atrium has rarely been performed. The authors report the first case of temporary filter insertion in the SVC because of upper extremity thrombosis accompanied with PE. After thrombectomy, the temporary filter was successfully removed. It is recommended to use a temporary filter, especially in young patients with upper extremity thrombosis requiring temporary prophylaxis against PE.
