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.
尽管脑动脉造影术通常作为一种诊断性放射学检查方法使用，但其应用并非完全无害。除了侵入性技术常见的并发症外，还可能遇到远端柔性导管尖端打结滞留的情况。本报告介绍了这样一个病例，即发生了这种情况，随后通过切开股动脉将其取出。
