419 Cerebrovascular Disease

Question 1

85% of ischemic stroke patients has this clinical manifestation (H20 C419 P3068)

Answer 1

Hemiparesis

Question 2

Syndrome caused by partial occlusion of a a single branch of the MCA causing hand, or arm and hand, weakness alone (H20 C419 P3071)

Answer 2

Brachial syndrome

Question 3

Syndrome caused by partial occlusion of a a single branch of the MCA causing facial weakness with nonfluent (Broca’s) aphasia with or without arm weakness (H20 C419 P3071)

Answer 3

Frontal opercular syndrome

Question 4

A combination of sensory disturbance, motor weakness, and nonfluent aphasia suggests that an embolus has occluded: (H20 C419 P3071)

Answer 4

Proximal superior division of the MCA

Question 5

If a fluent (Wernicke’s) aphasia occurs without weakness, this division of the MCA supplying the dominant hemisphere is probably involved (H20 C419 P3071)

Answer 5

Inferior division

Question 6

This segment of the anterior cerebral artery connects the ICA to the anterior communicating artery (H20 C419 P3071)

Answer 6

Precommunal (A1) circle of Willis

Question 7

The postcommunal (A2) segment of the ACA is the segment distal to this artery (H20 C419 P3071)

Answer 7

Anterior communicating artery

Question 8

Occlusion of this artery is usually well tolerated because of collateral flow through the anterior communicating artery and collaterals through the MCA and PCA (H20 C419 P3071)

Answer 8

Proximal ACA

Question 9

Profound abulia and bilateral pyramidal signs with paraparesis or quadriparesis and urinary incontinence result from occlusion of a single A2 segment in patients with this condition (H20 C419 P3071)

Answer 9

Contralateral A1 segment atresia

Question 10

P1 syndrome consisting of third nerve palsy with contralateral ataxia (H20 C419 P3073)

Answer 10

Claude syndrome

Question 11

P1 syndrome consisting of third nerve palsy with contralateral hemiplegia (H20 C419 P3073)

Answer 11

Weber syndrome

Question 12

Occlusion of this artery produces paresis of upward gaze and drowsiness and often abulia (H20 C419 P3073)

Answer 12

Artery of Percheron

Question 13

Usual manifestation of occlusion of the distal PCA causing infarction of the medial temporal and occipital lobes (H20 C419 P3073)

Answer 13

Contralateral homonymous hemianopia without macula sparing

Question 14

MCA strokes often produce hemianopia but typically spares the macula because this are is perfused by the P2 segment (H20 C419 P3073)

Answer 14

Calcarine cortex

Question 15

Visual hallucinations of brightly colored scenes and objects following occlusion of the PCA (H20 C419 P3074)

Answer 15

Peduncular hallucinosis

Question 16

Syndrome characterized by cortical blindness and unawareness or denial of this blindness (H20 C419 P3074)

Answer 16

Anton syndrome

Question 17

Disorder of the orderly visual scanning of the environment following bilateral visual association area lesions (H20 C419 P3074)

Answer 17

Balint syndrome

Question 18

Atherothrombotic lesions have a predilection for these segments of the vertebral arteries [2] (H20 C419 P3075)

Answer 18

V2, V4

Question 19

The constellation of vertigo, numbness of the ipsilateral face and contralateral limbs, diplopia, hoarseness, dys- arthria, dysphagia, and ipsilateral Horner’s syndrome is called the: (H20 C419 P3075)

Answer 19

Wallenberg or lateral medullay syndrome

Question 20

This imaging modality is helpful to detect cerebral microbleeds that may be present in cerebral amyloid angiopathy and other hemorrhagiv disorders (H20 C419 P3078)

Answer 20

Iron-sensitive imaging

Question 21

Much of the clinician’s stroke workup can be completed with this single imaging study (H20 C419 P3079)

Answer 21

CTA of the entire head and neck
