vessel preparation
Pre-stenting techniques including balloon pre-dilatation and plaque modification to optimize subsequent stent deployment and expansion.
Full Definition
Vessel preparation encompasses various pre-stenting interventional techniques designed to modify vessel geometry, plaque morphology, and luminal dimensions to optimize subsequent stent deployment and expansion. Standard vessel preparation includes balloon pre-dilatation with appropriately sized balloons to create adequate lumen for stent delivery and initial expansion. Advanced preparation techniques include rotational atherectomy for calcified lesions, cutting balloon angioplasty for fibrotic plaques, and intravascular lithotripsy for circumferential calcium. Proper vessel preparation is crucial for achieving optimal stent expansion, preventing complications such as stent underexpansion or incomplete apposition, and ensuring long-term procedural success. The extent of preparation is tailored to lesion characteristics, with heavily calcified or fibrotic lesions requiring more aggressive modification strategies.
