What is a main function of the Straight catheter in interventional radiology?

The primary function of a straight catheter in interventional radiology is to compress plaque or clot against the side of the vessel. This action is essential in procedures where visualization and access to blood vessels are crucial, such as in treating vascular occlusions. By applying a compressive force, the catheter can help to stabilize or push the clot or plaque against the vessel wall, potentially improving the ability to deliver therapeutic agents or medications directly to the area of concern.

This mechanical advantage of the straight catheter allows interventional radiologists to navigate complex vascular pathways and manage occlusions effectively. It is particularly valuable in facilitating better flow during procedures that require the removal or treatment of blockages within the vascular system. The use of a straight catheter is integral to many interventional techniques, as it helps in achieving the desired outcomes by managing how clots or plaques are maneuvered within the treatment area.
