What is a carotid string sign?

The angiographic string sign, also known as the carotid string sign or slim sign, refers to the thin string of intravascular contrast material distal to a stenotic focus in the internal carotid artery (ICA).

What is a CTA of the carotid artery?

CT angiography of the cerebral arteries (also known as a CTA carotids or an arch to vertex angiogram) is a noninvasive technique allows visualization of the internal and external carotid arteries and vertebral arteries and can include just the intracranial compartment or also extend down to the arch of the aorta.

How long can you clamp the carotid artery?

Contralateral stenosis was present in 324 (66.3%) patients with 82 (16.8%) having contralateral occlusion. Surgical parameters included the use of local anaesthesia in 493 (99.4%) of cases and the use of shunts in 76 (15.3%) cases. Carotid clamping time ranged from 1 to 45 min, with a median of 18 min.

What is eversion technique for carotid endarterectomy?

Eversion carotid endarterectomy (eCEA) involves oblique transection of the internal carotid artery (ICA) at its origin at the carotid bifurcation, followed by extirpation of the plaque by means of eversion and subsequent reimplantation of the ICA into the carotid bulb.

What does string sign mean?

String sign, or gastrointestinal string sign (also called string sign of Kantour), is a medical term for a radiographic finding on an upper GI series, in which the patient is given a radio-opaque material, such as barium, to drink. X-rays are then taken of the patient’s stomach and intestines.

What is a string sign in ultrasound?

The gastrointestinal string sign (also known as the string sign of Kantor) refers to the string-like appearance of a contrast-filled bowel loop caused by its severe narrowing.

How is a CTA performed?

CT angiography is a type of medical test that combines a CT scan with an injection of a special dye to produce pictures of blood vessels and tissues in a part of your body. The dye is injected through an intravenous (IV) line started in your arm or hand.

How long does an endarterectomy last?

The procedure A carotid endarterectomy usually takes 1 to 2 hours to perform. If both of your carotid arteries need to be unblocked, 2 separate procedures will be carried out. One side will be done first and the second side will be done a few weeks later.

What is carotid bulb?

The carotid sinus, also known as the carotid bulb, is a neurovascular structure that appears as a dilation at the bifurcation of the common carotid artery, and the beginning of the internal carotid artery.

What is patch angioplasty?

patch angioplasty: a local procedure whereby the artery is opened, the inside of the vessel is cleaned out and a patch of vein or prosthetic material is used to widen that area of the artery.

What is the carotid string sign in angiography?

The angiographic string sign, also known as the carotid string sign, refers to the thin string of intravenous contrast material distal to a stenotic focus in the internal carotid artery (ICA). Pathology. A thin stripe of flow is caused by decreased pressure and flow distal to the stenosis, which causes a collapse of the distal ICA. Aetiology.

Can near-occlusion distal carotid artery stenosis be reliably identified on CTA?

Near-occlusion distal ICAs can be reliably identified on CTA. Identification of near-occlusion stenosis with associated decreased diameter of the distal internal carotid artery (ICA) is essential for proper diagnosis and management of atherosclerotic carotid artery disease.

How accurate is CTCT angiography for diagnosing internal carotid artery stenosis?

CT angiography (CTA) is convenient and accurately quantifies internal carotid artery (ICA) stenosis. METHODS:In a blinded protocol, 268 carotid artery CTAs for known or suspected carotid disease were independently evaluated by 2 neuroradiologists.

How many carotid artery CTAs are there?

METHODS:In a blinded protocol, 268 carotid artery CTAs for known or suspected carotid disease were independently evaluated by 2 neuroradiologists. All carotid arteries were measured in millimeters at the narrowest diameter of the stenotic bulb, distal ICA well beyond the tapering bulb, and distal external carotid artery (ECA).
