Techniques for hemostasis of puncturing point after interventional management through femoral artery: its present situation and research progress

At the present time trans-femoral access remains the primary approach in performing coronary,cerebrovascular and peripheral artery interventions.However,the peri-procedural vascular complication of the puncturing point is still a concern that every interventional radiologist has to constantly confront.Hemostatic methods commonly used for trans-femoral access include manual compression,mechanical compression device,vascular closure device,etc.Since the mid-90 th of 20 th century different kinds of mechanical compression device and vascular closure device have been wildly employed in the clinical practice.With the help of these devices the postoperative bed rest time has been shortened to a certain degree and the patient's comfortableness has been greatly improved.Nevertheless,these devices have brought some complications.This paper aims to make a review of various clinically-used hemostatic methods for the puncturing point and to introduce the relevant research progress.
