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.

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

24. The correct order of the named segments of the anterior choroidal artery is
A. cisternal segment, plexal point, plexal segment
B. cisternal segment, plexal segment, plexal point

24 A .cisternal segment, plexal point, plexal segment

The anterior choroidal artery (AChA) is best seen on the
anteroposterior angiogram arising from the medial internal carotid artery.
The cisternal AChA curves medially and posteriorly around the uncus. An
abrupt "kink is seen at the plexal point where the AChA enters the choroidal
fissure. The plexal AChA then courses through the temporal horn.

Although this is the most common variation, others include the
inferior thyroid artery sharing a common trunk with the vertebral artery,
the vertebral artery from the thyrocervical trunk, the vertebral artery from
the proximal common carotid artery, and the vertebral artery from the
subclavian artery distal to the thyrocervical trunk.
