CEA Basics
This open surgical procedure removes atheromatous material from the carotid artery.
What is carotid endarterectomy (CEA)?
This closure technique uses only the arterial wall to close the arteriotomy.
What is primary closure?
This term means recurrent narrowing following treatment of the carotid artery.
What is restenosis?
CAS stands for this carotid intervention.
What is carotid artery stenting?
A normal carotid stent should have its walls in this relationship to the vessel walls.
What is apposed?
This is the surgical opening made in the artery during traditional CEA
What is an arteriotomy?
This closure technique uses additional material to enlarge the closure area.
What is patch closure?
This remnant of plaque after incomplete excision can cause early postoperative narrowing.
What is a shelf lesion?
This artery is usually used for vascular access during CAS.
What is the common femoral artery?
This is the most common location for stenosis following carotid stenting.
What are the stent borders?
Problems following CEA are more commonly found at this border of the endarterectomy site.
What is the distal ICA border?
These are the two general types of patch material described in the PowerPoint.
What are autogenous vein and synthetic patches?
During the first 24 months following CEA, restenosis is most commonly caused by this process.
What is neointimal hyperplasia?
This device is commonly placed before the carotid stent to reduce the risk of embolization.
What is an embolic protection device?
This Doppler measurement is the primary discriminator for significant post-CAS stenosis in the PowerPoint.
What is PSV?
In this type of CEA, the ICA is transected at the bifurcation, turned inside out, and the plaque is peeled away.
What is eversion CEA?
This synthetic patch has a woven appearance on ultrasound.
What is Dacron?
Restenosis occurring more than 2 years after CEA is associated with this disease process.
What is atherosclerosis?
This balloon procedure is performed before placement of the self-expanding stent.
What is predilation?
Because a stent creates a rigid matrix, it decreases this property of the artery, which can cause velocities to increase even without stenosis.
What is compliance?
Compared with primary closure, this CEA technique has less restenosis, but its restenosis rate is equivalent to CEA performed with a patch.
What is eversion CEA?
This synthetic patch appears as two brightly echogenic lines on ultrasound.
What is PTFE?
Air trapped in the patch and wound hematomas may make an early postoperative scan difficult; this scanning approach may help.
What is a posterior approach?
The carotid stent should cover the entire lesion and extend this distance beyond both its proximal and distal margins.
What is 5 mm?
A PSV above approximately this value is described as a relatively good predictor of high-grade restenosis after CAS.
What is 325 cm/s?
