    Abstract：Seldinger technique is inevitably involved in the intravascular interventional diagnosis and treatment. A modified Seldinger technique has more advantages and interventional equipments have many improvements, which make it possible that puncture catheter is safe and effective by one person. The discussion on the operational procedure of puncture catheter by one person is favorable for the development of intravascular interventional diagnosis and treatment. It is proved from practice that this technique is not only simple and easy but also accurate and safe, and without any complications. ......
