AI Article Synopsis
- The study evaluates the microsurgical anatomy of the pericallosal artery, highlighting an unusual brain with three unique anatomical variations.
- Researchers meticulously prepared a brain from a deceased 45-year-old female by washing out arteries, injecting them with red latex, and then preserving the brain in formalin for detailed dissection.
- Three rare anatomical variants were discovered: a right accessory middle cerebral artery, a right bihemispheric anterior cerebral artery, and a median artery of the corpus callosum, illustrating the rarity of finding these combinations in one case.
Article Abstract
Background: As part of a study of the microsurgical anatomy of the pericallosal artery, we describe one brain with three unusual anatomical variants.
Methods: From the autopsy of a 45 year-old female, we extracted the brain and all the arterial blood vessels were washed off with saline solution to be injected afterwards with red latex. The brain was then immersed in 10% formalin for two months. Finally, we dissected and measured the internal carotid artery segments, using a digital Vernier caliper under a Carl Zeiss OPMI surgical microscope with magnification of 6x up to 40x.
Results: The brain's weight was 1250 grams and three rare anatomical variants were found: 1) right accessory middle cerebral artery (ACMA-d), 2) right bihemispheric anterior cerebral artery (ACABihem-d), 3) median artery of the corpus callosum (AMCC).
Conclusion: The association of the anatomical variations described previously is inconstant; furthermore, their appearance in a single case is rare.
