type II endoleak
Retrograde flow into the aneurysm sac through patent branch vessels, most commonly lumbar arteries or inferior mesenteric artery.
claudication distance
Specific walking distance at which a patient develops leg pain due to inadequate blood flow during exercise.
collateral circulation
Alternative blood flow pathways that develop to bypass blocked or diseased arteries.

compartment syndrome
Acute condition where increased pressure within muscle compartments compromises circulation and tissue viability.
completion angiography
Intraoperative imaging performed after vascular reconstruction to verify technical adequacy.
critical limb ischemia
Advanced peripheral arterial disease with rest pain, tissue loss, or gangrene.
Dacron

endarterectomy
Surgical removal of plaque and thickened arterial lining to restore blood flow.
endograft
Stent-graft device inserted via minimally invasive technique to treat aneurysms from within the blood vessel.

fasciotomy
Surgical division of fascial compartments to relieve pressure and restore circulation.
femoral-popliteal bypass
Surgical procedure creating an alternate pathway around blocked femoral and popliteal arteries in the leg.

Fontaine classification
A four-stage system for classifying peripheral arterial disease severity based on clinical presentation.
graft surveillance
Regular monitoring of bypass grafts to detect stenosis or failure.
graft thrombosis
Blood clot formation within a surgical bypass graft, leading to graft failure and loss of blood flow.
