Lower extremity swelling: computerized tomography following negative venography.
In 21 patients who had lower extremity swelling and negative venography, radiographic evaluation was extended to include computerized tomography (CT) of the lower extremity, which we have termed venography-CT, or VCT. All patients were referred with the diagnosis of deep vein thrombosis (DVT) and no patient had a history of trauma. CT was effective in demonstrating two occult mechanisms of lower extremity swelling: knee joint effusion (three patients) and intramuscular hemorrhage (five patients). Selective utilization of CT in the evaluation of lower extremity swelling is effective in directing the clinical management of these patients.
