retrograde percutaneous intervention
Advanced technique approaching coronary occlusions through collateral vessels in reverse direction of normal flow.
Full Definition
A specialized approach for treating complex coronary lesions, particularly chronic total occlusions, where guidewires and equipment are advanced through collateral circulation from a different coronary vessel, proceeding against the normal direction of blood flow. This technique requires advanced operator expertise and is typically reserved for cases where conventional antegrade approaches have failed. The procedure involves complex wire manipulation, balloon techniques, and specialized equipment designed for retrograde access.
Usage
Usage note: Reserved for complex cases; document collateral vessel used and crossing strategy.
