Abstract

Background: The study of the cerebellar arteries has increased. The purpose of this study was to determine the morphological expression of posterior inferior cerebellar artery in a sample of Colombian population. Materials and methods: 186 posterior inferior cerebellar arteries of fresh cadavers were studied. In each specimen, vertebral arteries were injected with 100 ml of semi-synthetic resin, dyed with mineral red. Results: The cerebellum evaluated, 174 (93.5%) posterior inferior cerebellar artery were found. Also, there were 12 (6.5%) agenesis. There was single posterior inferior cerebellar artery in 159 (91.4%) samples and duplicate in 10 (5.7%), while five (2.9%) specimens showed hypoplasic. The posterior inferior cerebellar artery originated from the vertebral artery in 121 samples (69.5%) and from the basilar artery in 42 (24.1%) samples; while in 11 (6.4%) originated in a common trunk with the anterior inferior cerebellar artery. In 101 (83.5%) cases, the posterior inferior cerebellar artery originated from the intracranial segment of the vertebral artery, while 20 samples (16.5%) originated from the extracranial segment. The calibers of posterior inferior cerebellar artery in its proximal and distal segments were 1.45±0.37 mm and 1.33 ± 0.31 mm respectively. Conclusions: This study, carried out in cadaveric material, provides relevant qualitative and morphometric information of the posterior inferior cerebellar artery, useful for the diagnosis and clinical management, as well as for the surgical approaches that may compromise this structure.
