Özet

Introduction: The arteries of the anterior perforated substance (APS) are important due to their role in supplying blood to important internal structures such as the internal capsule, putamen and caudate nucleus. The purpose of this study was to investigate in detail the arteries of the APS. Methods: The arteries of t h e AP S were investigated in 60 cerebral hemispheres from 30 adult cadaveric brains. The internal carotid arteries were cannulated and perfused with coloured latex. The branches of the middle cerebral artery (MCA) penetrating the APS were investigated. These arteries, known as the lateral lenticulostriate arteries and originating from the M1 segment, early temporal and early frontal branches of the MCA, were recorded. Results: The branches of the anterior choroidal artery, which reached the APS, were seen in all specimens. We found one to three branches that arose from the A2 segment of the anterior cerebral artery (ACA) to the APS in all hemispheres, and one to three branches that originated from the A1 segment of the ACA in 48 hemispheres. In addition, two accessory MCAs that originated from the A2 segment of the ACA were recorded as variations, and perforating branches to the APS were observed. Conclusion: Serious complications like motor defcits can occur as a result of injury to the arteries of the APS. Hence, neurosurgeons performing operations such as aneurysm or insular tumour surgeries must be aware of the importance of preserving these arteries.
