Q. Explain Femoral Approach?

This approach involves the insertion of a catheter over a guidewire i.e. inserted into a sheath in the right femoral artery. Systemic anticoagulation is used (heparin). A series of preformed catheters are employed for the procedure - commonly the Judkins left and right catheter and the pigtail catheter though a host of other catheters are available for individual anatomical variations. The common size of catheters used are: 5F, 6F, 7F and 8F. The 6F size is now commonly used all over the world for diagnostic adult procedures.
