type II endoleak
Retrograde flow into the aneurysm sac through patent branch vessels, most commonly lumbar arteries or inferior mesenteric artery.
post-thrombotic syndrome
Chronic venous insufficiency and associated symptoms developing after deep vein thrombosis due to valvular incompetence...
pressure gradient
Measurable pressure difference across a vascular stenosis indicating hemodynamic significance.
profundaplasty
Surgical reconstruction of the profunda femoris artery to improve deep femoral circulation.
pseudoaneurysm
False aneurysm where blood is contained by surrounding tissue rather than vessel wall.
PTA
Percutaneous transluminal angioplasty - minimally invasive procedure to open narrowed blood vessels using balloon inflat...
PTFE
Polytetrafluoroethylene; a synthetic graft material commonly used in vascular surgery.
Pulse volume recording
A non-invasive test that measures volume changes in blood flow through pressure cuffs to assess arterial circulation.
retrograde flow
Blood flow in the opposite direction from normal anatomical circulation patterns.
revascularization
Surgical or endovascular restoration of blood flow to ischemic tissue through bypass grafting or angioplasty.
runoff
Distal arterial circulation beyond a stenosis or bypass target.
runoff vessels
Distal arteries that receive blood flow from a more proximal vessel, crucial for determining bypass target selection.
Rutherford classification
A standardized system for categorizing the severity of peripheral arterial disease based on clinical symptoms and object...
saphenous vein graft
Autogenous conduit harvested from the patient's own great saphenous vein for arterial bypass procedures.
steal syndrome
Redirection of blood flow causing ischemia in one area to supply another.
stent fracture
Mechanical failure of an implanted stent resulting in discontinuity of the stent structure, often leading to restenosis...
target vessel
The specific artery or vein selected as the recipient or destination for a vascular intervention or bypass procedure.
TEVAR
Thoracic endovascular aortic repair - minimally invasive treatment for thoracic aortic aneurysms using stent-grafts.
Thoracic endovascular aortic repair
An endovascular technique for treating thoracic aortic pathology using stent-grafts deployed in the descending thoracic...
thrombectomy
Surgical or catheter-based removal of blood clot from vessels.
tissue loss
Ulceration, gangrene, or non-healing wounds indicating severe ischemia and advanced peripheral arterial disease requirin...
Toe-brachial index
A diagnostic ratio comparing toe systolic pressure to brachial systolic pressure, particularly useful in patients with n...
Transatlantic Inter-Society Consensus
A standardized classification system (TASC) for aortoiliac and femoropopliteal arterial lesions used to guide treatment...
Transcutaneous oximetry
A non-invasive test measuring oxygen tension through the skin to assess tissue perfusion and wound healing potential.
type II endoleak
Retrograde flow into the aneurysm sac through patent branch vessels, most commonly lumbar arteries or inferior mesenteri...
