in the first 24 hours after cerebral angiography?
I. age over 70 years
II. duration of angiogram over 90 minutes
III. history of transient ischemic attack (TIA) or stroke
IV. history of systemic hypertension
A. I, II, III
B. I, III
C. II, IV
D. IV
E. all of the above
1 E .
I. age over 70 years
II. duration of angiogram over 90 minutes
III. history of transient ischemic attack (TIA) or stroke
IV. history of systemic hypertension
Morris p. 63. Other risk factors include patients with more than 50 to 70%
stenosis of the cerebral vessels, patients whose angiograms require a higher
volume of contrast, and patients referred for subarachnoid hemorrhage or
who are immediately postoperative.
2 The most common nonneurologic complication of cerebral angiography via femoral artery approach is A. angina B. allergic reaction C. hematoma D. myocardial infarction (MI) E. pseudoaneurysm
2 C. hematoma
Significant hematoma formation occurs at a rate of approximately
6.9 to 10.7%. Angina, allergic reaction. and myocardial infarction (MI)
all occur with an incidence of less than 1 to 2%. Pseudoaneurysms are rare.
occurring 0.05 to 0.55% of the time.
3. Branches of the meningohypophysial trunk include the I. tentorial artery II. inferior hypophysial artery III. dorsal meningeal artery IV. superior hypophysial artery A. I, II, III B. I, III C. II, IV D. IV E. all of the above
3A
I. tentorial artery
II. inferior hypophysial artery
III. dorsal meningeal artery
Osb p. 87. The meningohypophysial trunk, the largest and most proximal branch
of the cavernous carotid artery, typically has three branches: the tentorial artery
(of Bernasconi and Cassanari), the dorsal meningeal artery, and the inferior
hypophysial artery (the inferolateral trunk). The superior hypophysial artery
is a branch of the supraclinoid carotid artery.

6. proximal cavernous internal carotid artery to basilar artery A. cervical intersegmental artery B. proatlantal intersegmental artery C. primitive hypoglossal artery D. primitive otic artery E. primitive trigeminal artery
E. primitive trigeminal artery
7. The precentral cerebellar vein usually drains into the A. internal cerebral vein B. lateral mesencephalic vein C. posterior mesencephalic vein D. straight sinus E. vein of Galen
E .vein of Galen
Osb p. 233. The precentral cerebellar vein is a midline vessel that courses
medially over the brachium pontis, parallels the roof of the fourth ventricle,
and curves upward behind the inferior colliculus and precentral lobule of the
vermis to drain into the vein of Calen.
8. Anterior temporal lobe masses characteristically displace the A. anterior choroidal artery laterally B. anterior choroidal artery medially C. anterior choroidal artery upward D. posterior choroidal artery downward E. posterior choroidal artery upward
B.anterior choroidal artery medially
