sandwich technique
A stenting method where a covered stent is placed between two uncovered stents to treat complex lesions while preserving side branch patency.
access site crossover
Procedural technique requiring catheter navigation from one arterial access point to the contralateral vascular system.
angiographic blush
Radiographic appearance of contrast enhancement in tissue capillaries, indicating microvascular perfusion status.
angiographic success
Achievement of less than 20% residual stenosis with normal flow following interventional treatment.
AngioJet thrombectomy
Mechanical thrombectomy system using high-velocity saline jets to fragment and aspirate thrombus.
antegrade approach
Vascular access technique where devices are introduced in the direction of normal blood flow.
arteriovenous malformation
Congenital vascular lesion with abnormal direct connections between arteries and veins.
aspiration thrombectomy
Mechanical clot removal technique using suction through a large-bore catheter to extract thrombus from cerebral or perip...
atherectomy
A procedure that uses cutting, grinding, or laser devices to remove atherosclerotic plaque from inside blood vessels.
bailout stenting
Emergency stent deployment to manage acute procedural complications such as dissection or abrupt vessel closure.
balloon guide catheter
Specialized guide catheter with inflatable balloon tip for flow arrest and embolic protection during neurovascular inter...
balloon-expandable stent
A type of stent that is deployed by inflating a balloon catheter to expand the metal framework against vessel walls.
bifurcation lesion
A coronary narrowing at the junction where a vessel divides into two branches, requiring specialized stenting techniques...
bioresorbable scaffold
Temporary stent device designed to dissolve completely after providing initial vessel support.
bird's beak sign
Angiographic appearance of abrupt vessel tapering resembling a bird's beak, indicating severe stenosis or occlusion.
blue toe syndrome
Clinical manifestation of distal embolization causing cyanotic digits despite palpable pedal pulses.
buddy wire
An additional guidewire placed alongside the primary wire to provide extra support or maintain access during complex pro...
cheese-grater effect
Vessel wall trauma caused by repeated passage of devices through severely calcified or stenotic lesions.
CHIP
Systematic approach to identifying high-risk coronary lesion characteristics that may complicate intervention.
claudication distance
Standardized walking distance at which a patient develops leg pain due to arterial insufficiency.
coil embolization
Technique using detachable metal coils to occlude blood vessels or aneurysms by inducing thrombosis.
collateral circulation
Alternative blood flow pathways that develop to bypass chronically occluded vessels.
compliance mismatch
Difference in vessel wall flexibility between treated and untreated segments, potentially affecting long-term outcomes.
contrast staining
Persistent retention of contrast agent within the vessel wall, indicating dissection or vessel wall injury.
contrast-induced nephropathy
Acute kidney injury that develops following exposure to iodinated contrast media during vascular procedures.
