Vascular Intervention Glossary

Metallic indicators on medical devices that provide visibility under fluoroscopy during vascular procedures.

The re-narrowing of a blood vessel following interventional treatment such as angioplasty or stenting.

Technique using high-speed rotating burr to ablate calcified plaque and facilitate balloon or stent delivery.

Distal arteries that provide outflow from a treated vessel or bypass graft.

Standardized system for grading chronic limb ischemia severity in peripheral arterial disease.

A stenting method where a covered stent is placed between two uncovered stents to treat complex lesions while preserving...

Blood clot formation within a bioresorbable coronary scaffold, representing a device-specific complication.

A vascular stent made of nitinol or similar material that automatically expands to predetermined diameter when deployed.
