Near the superior frontal gyrus, these arteries anastomose with branches from the pericallosal artery
of the anterior cerebral artery.
After the separation of the two cingulate gyri, we may identify the pericallosal artery
running over a white shining structure that is the corpus callosum (Figure 5).
Cerebral artery MR angiography, bilateral carotis arteries, anterior cerebral artery, pericallosal artery
and mid cerebral artery, Willis Polygon arterial structures, basilar artery, and arteria cerebri posterior branches were normal; no aneurysm, malformation or displacement were detected; venous MR angiography revealed a slightly weakened right transverse sinus calibration (variation) and normal sagittal sinus, straight sinus, left transverse and sigmoid sinus alignments and calibrations.
of California, San Francisco) details the basic concepts and tenets of aneurysm microsurgery, various craniotomies and exposures for successful clipping, and microsurgical anatomy, dissection strategies, and clipping techniques for each of the seven most common aneurysm types: posterior and anterior communicating artery, middle cerebral artery, ophthalmic artery, basilar bifurcation, pericallosal artery
, and posterior inferior cerebellar artery aneurysms.
