Intra-arterial knotted catheter.
Although cerebral arteriography is commonly employed as a diagnostic radiologic procedure its use is not entirely innocuous. Beside the usual complications of an invasive technique the retention of a knotted distal flexible catheter tip may be encountered. This report presents a case in which this occurred with subsequent extraction by way of incision of the femoral artery.
