The Arteries of the Corpus Callosum: A Microsurgical Anatomic Study

Abstract

Familiarity with the details of the vascularity of the corpus callosum is crucial when performing surgery in this region. The additional, significant data described expands the knowledge of this anatomy, which can enhance the surgeon's ability to accomplish a more accurate and successful exploration.

Brain Commissural Anomalies

“…The carotid system contributes mainly to this supply via the pericallosal artery Wolfram-Gabel et al, 1989;Türe et al, 1996) which is the main artery of the corpus callosum (Wolfram-Gabel et al, 1989;Türe et al, 1996). It curves around the genu and continues posteriorly along the dorsal surface of the corpus callosum (Yasargil, 1984).…”

“…Usually, some of the branches arising from this network circle around the splenium and joint with branches of the medial posterior choroidal arteries in the tela choroidea of the third ventricle. In addition to pericallosal artery, the anterior communicating artery accessorily contributes to it by an inconstant artery called median artery of the corpus callosum (Wolfram-Gabel et al, 1989;Türe et al, 1996). The pericallosal artery gives rise to four types of branches that supply the corpus callosum, these are the callosal artery; cingulocallosal artery; long callosal artery; and recurrent cingulocallosal artery.…”

“…The pericallosal artery gives rise to four types of branches that supply the corpus callosum, these are the callosal artery; cingulocallosal artery; long callosal artery; and recurrent cingulocallosal artery. The callosal arteries are thin branches which directly supply the indusium griseum and the superficial surface of the corpus callosum in the midline (Kahilogullari et al, 2008;Türe et al, 1996). The cingulocallosal arteries bring the chief supply to the corpus callosum.…”

“…These arise from the inferolateral aspect of the pericallosal artery and run laterally into the callosal sulcus, where they are divided into three arterial subgroups (Türe et al, 1996) which supply the corpus callosum, the cingulate gyrus and the radiation of the corpus callosum.The cingulocallosal arteries anastomosing with each other and with branches arising from the subcallosal, median callosal and long callosal arteries to form the pericallosal pial plexus. The long callosal artery is found almost in half of the hemispheres, it is an another branch arising from the pericallosal artery, courses parallel with it in the callosal sulcus and has multiple branches that contributed to the pericallosal pial plexus (Kahilogullari et al, 2008;Türe et al, 1996) .The artery ends in the body of the corpus callosum or in the medial longitudinal striae at the splenium and anastomosis with the posterior pericallosal artery of the same hemisphere or is crossed the midline and anastomosed with the posterior pericallosal artery of the opposite hemisphere, both within the callosal sulcus in the splenial region. The recurrent cingulocallosal artery is a thin branch, arises from major cortical branches of the pericallosal artery: It courses on the medial surface of the cingulate gyrus toward the callosal sulcus, present in 45% of the subjects (Türe et al, 1996) and contributed to the pericallosal pial plexus (Kahilogullari et al, 2008;Türe et al, 1996).…”

In addition to the pericallosal artery, the perforating branches of the anterior communicating artery participate in providing blood supply to the corpus callosum.The hypothalamic artery (which do not supply the corpus callosum); subcallosal artery; and median callosal artery spring from these branches.…”
