CCI RVS CRANIAL: Carotid & Vertebral Artery Anatomy & Pathology Q&A, Exams of Public Health

Chamberlain College of NursingPublic Health

This resource provides a comprehensive overview of the anatomy and pathology of the carotid and vertebral arteries. It covers topics such as artery branches, blood pressure control, chemoreceptors, carotid bifurcation, and various diseases like polycythemia vera, TIA, and CVA. It also delves into the anatomy of intracranial venous sinuses, cerebral artery supply, and the use of transcranial Doppler (TCD) for evaluating intracranial stenosis and vasospasm. The resource further explores the common locations for plaque formation, the Doppler criteria for ICA stenosis, and the assessment of carotid artery disease.

CCI RVS CRANIAL: QUESTIONS WITH PERFECT

ANSWERS (100% CORRECT)

Innominate Artery Branches Right Ans - Right CCA and Right Subclavian Carotid bulb contains Right Ans - baroreceptors that assist in blood pressure control Carotid body contains Right Ans - chemoreceptors CCA bifurcates at Right Ans - upper border of thyroid cartilage ECA branches Right Ans - provide collateral pathways for intracranial stenosis ECA Nl PSV Right Ans - <150 cm/s VA's supply Right Ans - 10 - 25% of cerebrum VA Nl PSV Right Ans - < 50 cm/s Basilar Artery bifurcates Right Ans - at Circle of Willis to form cerebral arteries ACA supplies Right Ans - Cava septum pellucidum Corpus callosum Frontal & parietal lobes MCA supplies Right Ans - Frontal Parietal Temporal PCA supplies Right Ans - Occipital Temporal Cerebral circulation: Sups Right Ans - Branches spread over surface of brain

Cerebral circulation: penetrating branches Right Ans - Enter brain tissue segments for nutrient exchange and neuronal function Cerebral circulation: Intracranial venous sinuses Right Ans - Located between dura mater and periosteum drain cerebral blood into IJV Polycythemia Vera Right Ans - Thickened blood reduces flow and leads to distal ischemia, increased risk of thrombus/embolus formation

1.2 mm IMT Right Ans - Increased risk for stenosis TIA symptoms Right Ans - < 24 hours CVA symptoms Right Ans - > 24 hours Subarachnoid Hemmorhage Right Ans - Rupture of intracranial vessel RICA stenosis Right Ans - Lt side paresis, paresthesia LICA stenosis Right Ans - Rt side paresis, paresthesia Amaurosis Fugax Right Ans - Temporary monocular blindness "TIA of eye" ICA Disease Right Ans - Unilateral symptoms with contralateral stenosis Amaurosis Fugax Broca Aphasia Hemiparesis Homonymous Hemianopia Paralysis Paresthesia MCA Disease Right Ans - Behavioral changes Dysphasia Hemiparesis Wernicke Aphasia AKA receptive aphasia ACA Disease Right Ans - Facial Droop/Assymetry Incontinence

P1 Transtemporal Right Ans - 60 - 70 mm toward ACA transtemporal Right Ans - 60 - 80 mm Away P2 transtemporal Right Ans - 60 - 70 mm Away Basilar Suboccipital Right Ans - 80 mm away Transorbital Right Ans - Opthalmic Artery and carotid siphon Opthalmic transorbital Right Ans - Adjacent to optic nerve Toward Submandibular Right Ans - Distal ICA & siphon Away ACA/MCA Nl Velocity Ratio Right Ans - <1. MCA/ICA Nl Velocity Ratio Right Ans - 1.1 - 3. Basilar/Vertebral Nl Velocity Ratio Right Ans - <2. Nl PI Right Ans - 0.5 - 1. ECA to ICA collateralization Right Ans - flow reversal in ipsilateral opthalmic TCD for Vasospasm Right Ans - Complication in subarachnoid hemorrhage, usually slow bleed PI > 1.2 Right Ans - Vasospasm MCA > 200 cm/s & TAMV > 120cm/s Right Ans - Severe significant reduction in intracerebral flow

Absence of 1 or more communicating arteries Right Ans - Most common Circle of Willis anomaly TCD most common indication Right Ans - Vasospasm/Vasoconstriction caused by subarachnoid hemmorhage TCD evaluation Right Ans - TAMV most common Intracranial stenosis most common in Right Ans - MCA, siphon, terminal ICA Anterior communicating artery Right Ans - most common collateral pathway for ICA disease ACoA most common location for Right Ans - Intracranial aneurysm PCoA second most common location for Right Ans - Intracranial aneurysm Intracranial Arteriovenous Malformation Right Ans - Most common in men Pre-Stenotic Zone Right Ans - Dampened flow velocity with loss of diastolic flow Increased resistance and RI Short Acceleration Time (AT) Stenotic Zone Right Ans - Decreased Pressure Increased Diastolic flow High PSV Spectral broadening Post Stenotic Zone Right Ans - Increased diastolic flow Low resistance Turbulence Distal to Critical ICA Stenonsis Right Ans - Diastolic and systolic flow is low-velocity with blunted waveform Slow AT Tardus-parvus

Kinking of ICA Right Ans - Most common anatomic variant associated with symptomatic cerebral ischemia Plaque in carotid bifurcation Right Ans - Most common cause of stroke Cardiac emboli Right Ans - Second most common cause of stroke MCA Right Ans - Most commonly occluded intracranial vessel with acute stroke Distal CCA IMT measurement Right Ans - Most commonly used to assess cardiovascular events Most common location of VA stenosis Right Ans - Origin Most common side for subclavian steal Right Ans - Left Extracranial ICA Right Ans - More common site for dissection than intracranial ICA FMD Right Ans - Most common in mid-distal ICA Atherosclerosis Right Ans - Most common in proximal ICA Eagle Syndrome most common location Right Ans - Bilateral Nintinol Right Ans - Most common stent material Supra orbital artery Right Ans - direct branch from the ophthalmic artery and joins the superficial temporal artery, which is a branch of the external carotid artery 15 MHz Right Ans - transducer for intraoperative carotid US State of px CCA best evaluated by Right Ans - Systolic upstroke Short focal plaque Right Ans - May overestimate stenosis
