Vascular ARDMS 2023 with 100% correct questions and answers

First major branch of the aorta? Innominate/brachiocephalic artery A TIA of the right anterior hemisphere of the brain will affect? The left side of the body. Will affect the opposite side Amaurosis Fugax related to internal carotid lesion: Temporary blindless affecting the same side of lesion Simultaneous bilateral ocular symptoms in a patient with cerebrovascular disease originate from? The vertebrobasilar arteries Symptoms associated with vertebrobasilar circulation: Vertigo, dizziness, ataxia, or other bilateral or global symptoms Symptoms associated with anterior circulation: Facial asymmetry, unilateral Infraorbital artery is a terminal branch of the: Maxillary artery Dysphagia Difficulty swallowing that's associated with vertebrobasilar insufficiency Patient has 30 minute episode of garbled speech, which is called: Dysphasia. (Aphasia absence of speech) Right handed patient experiences 30 minute episode of dysphasia. Which area of circulation is suspected? Left hemisphere. Speech area of the cortex is temporal lobe Bruits are caused by? Turbulent flow. Severe stenosis may not cause bruit, often they disappear near preocclusive Brachial blood pressure are obtained bilaterally for evaluating a patient for cerebrovascular disease because: If one pressure is 15-20 mmHg less than the other, subclavian steal is suspected on the side of the lower pressure Transcranial findings consistent with vasospasm following subarachnoid hemorrhage would include: Increased mean velocities in the MCA In TCD, the normal direction of flow in vertebral artery is: Away from the beam. Suboccipital, foramen magnum approach flow should normally be away from the beam TCD probe with frequency of: 2 MegaHertz Transtemporal window of TCD, normal direction of flow in the ACA is: Away from the beam The circle of Willis receives its blood supply form which arteries? Carotid and vertebral arteries Characteristics of ECA: Prominent dicrotic notch, a sharp peak and little diastolic flow Characteristics of ICA: Lots of diastolic flow, less distinct peak, less prominent dicrotic notch The three terminal branches of the ophthalmic artery are the: Nasal, frontal, and supraorbital arteries TCD using transtemporal window, normal direction of flow in the cerebral artery: Towards the beam Using TCD, you find strong signal with diastolic flow at depth of 50mm. Most likely: MCA. 30-60 mm is the depth with velocity of 43-67cm/s TCD window for assessing the MCA is: Temporal Two of the major branches of the ECA include: Superficial temporal and facial arteries TCD window used for assessing ophthalmic artery and carotid siphon is: Orbital TCD exam, waveform in the suboccipital window, depth is to be 90 mm. This is most likely: Basilar artery Collateral pathways of ICA obstruction: Posterior to anterior, contralateral hemisphere, ECA branches to ophthalmic branches The most common arterial puncture site for all forms of angiography, including cerebral, is the: Common Femoral artery The two arteries creating bidirectional signal observed 60-65 mm deep during TCD of temporal window are: MCA and ACA Another name for internal mammary artery? Internal thoracic artery Most common anomaly of circle of Willis? Absence of hypoplasia of one or both communicating arteries What factor is least likely to contribute to deep venous thrombosis? Diabetes - is risk factor for atherosclerosis, not DVT Pitting edema of both lower extremities is likely related to? Cardiac, with congestive heart failure Findings of skin discoloration in a patient with chronic venous insufficiency are: Rusty brown color at ankles and calves Most reliable method for diagnosis of pulmonary embolism? Pulmonary angiography Boyd's perforating vein is located: Near the knee Thrombosis that appears dark, homogeneous, and poorly attached to the venous wall suggests: Acute thrombosis Pulsatile lower extremity venous Doppler signals would be associated with: Congestive heart failure Venous puncture for contrast in venography to asses for deep venous thrombosis is done at what level? Dorsal vein on the foot Venous puncture for contrast in venography to assess for valvular insuffiency is done at what level? Common femoral vein
