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.

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.

Q
  1. 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
    C. plexal point, cisternal segment, plexal segment
    D. plexal point, plexal segment, cisternal segment
    E. plexal segment, plexal point, cisternal segment
A

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.

Q
  1. In the most common anatomic variation, the named branches of the proximal
    right subclavian artery from proximal to distal are
    A. internal mammary artery, thyrocervical trunk, vertebral artery,
    costocervical trunk
    B. internal mammary artery, vertebral artery, thyrocervical trunk,
    costocervical trunk
    C. vertebral artery, internal mammary artery, costocervical trunk,
    thyrocervical trunk
    D. vertebral artery, internal mammary artery, thyrocervical trunk,
    costocervical trunk
    E. vertebral artery, thyrocervical trunk, internal mammary artery.
    costocervical trunk
A

25 D.vertebral artery, internal mammary artery, thyrocervical trunk,costocervical trunk

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.
