Oversizing a balloon during angioplasty is associated with which risk?

Explanation:
Excessive radial force from inflating a balloon bigger than the vessel can tear the inner lining of the artery, creating a dissection. An intimal tear can split the wall and form a false lumen that may reduce or block true lumen flow, sometimes needing a stent to seal the tear. While thrombosis or occlusion can occur in PCI for other reasons, oversizing is most directly linked to vessel dissection.
