![]() ![]() The flocculo-nodular lobe is usually supplied by 2 arteries: the flocculus is supplied by the AICA and the nodulus is supplied by the PICA. It supplies the lobulus semilunaris inferior, the lobulus gracilis, the lobulus biventer, the tonsilla cerebelli, and, in the vermis, the clivus, the tuber, the pyramis, the uvula and the nodulus. It is one of the three main arteries that supply blood to the. ![]() Venous drainage of the cerebellum is by the superior and inferior cerebellar veins. The PICA is a branch of the vertebral artery. The PICA always gives rami to the group of arteries supplying the dorsal medullary territory, but rarely participates to the supply of the lateral medullary territory. The posterior inferior cerebellar artery (PICA) is the largest branch of the vertebral artery. The SCA and AICA are branches of the basilar artery, which wraps around the anterior aspect of the pons before reaching the cerebellum. When the posterior inferior cerebellar artery (PICA) is hypoplastic, AICA takes over the territory usually supplied by the lateral branch of the PICA. Dealing with abdominal lipectomy and flaps or microanostomes centered over an arterial pedicle, the authors have reassessed the arterial blood supply of the abdominal wall (the venous blood supply. It usually supplies the lateral territory of the lower part of the pons, the middle cerebellar peduncle, the flocculus and the neighbouring lobules of cerebellum. The anterior inferior cerebellar artery (AICA) irrigates a ponto-cerebellar territory. The dentate nucleus belongs to this territory. We identified most of SCA compression from superior, most of AICA from. The superior part of the cerebellum supplied by this artery includes the following lobules: lobulus anterior, lobulus simplex, lobulus semilunaris superior, and, in the vermis, lobulus centralis, culmen and clivus. PICA is the most common artery compressing the inferior cranial nerves from superior. The superior cerebellar artery (SCA) supplies a small brain stem territory, located on the dorsal tegmentum and the tectum of the upper part of the pons. Summary: Double origin of the posterior inferior cerebellar artery (PICA) has rarely been demonstrated by angiography in the peer-reviewed literature. anastomoses between the anterior and posterior spinal arteries thus making the artery of Adamkiewicz similar to an end artery. They are based on a neuropathological study of 64 cases of cerebellar infarctions, the detailed study of which is reported elsewhere. The posterior spinal arteries can branch off the posterior inferior cerebellar artery (PICA). Anatomical drawings of the territory of these arteries are presented. Origin, course and distribution of the cerebellar arteries and of their branches are described. Posterior inferior cerebellar artery (PICA) is the largest branch of the vertebral artery, originating from the intracranial portion of the vertebral artery 1020 mm before the vertebrobasilar junction, but the origins are highly variable and may arise from the basilar artery, extracranial portion of the vertebral artery, or ascending. ![]()
