The posterior inferior cerebellar artery (PICA) is the largest branch of the vertebral artery. It is one of the three main arteries that supply blood to the cerebellum, a part of the brain. Blockage of the posterior inferior cerebellar artery can result in a type of stroke called lateral medullary syndrome.

2023年3月19日 · Posterior inferior cerebellar artery (PICA) is one of the three vessels that provide arterial supply to the cerebellum. It is the most variable and tortuous cerebellar artery.

The posterior inferior cerebellar artery (PICA), with its unique anatomical complexity, is of great clinical importance and involved in many diseases including aneurysm, ischemic stroke, neurovascular compression syndrome (NVCS), arteriovenous …

2025年1月6日 · Named after Adolf Wallenberg in 1895, this neurological condition is characterized by lateral medullary infarction resulting from an occlusion of the posterior inferior cerebellar artery (PICA) or the vertebral artery. Typically, this is due to an atherothrombotic occlusion, which is when a blood clot blocks one of the arteries that supply the ...

2025年1月14日 · Posterior inferior cerebellar artery (PICA) occlusion may cause infarction of any part of the vascular territory of the PICA, namely the posterior inferior cerebellum, inferior cerebellar vermis, and lateral medulla.

The posterior inferior cerebellar artery (PICA) winds backward around the upper part of the medulla oblongata, passing between the origins of the vagus nerve and the accessory nerve, over the inferior cerebellar peduncle to the undersurface of the cerebellum, where it …

2023年10月1日 · The posterior inferior cerebellar artery (PICA) arises from the distal portion of the vertebral artery (VA). The antero-medullary segment ( 1 ) courses below the hypoglossal nerve (XII) and ends at the most prominent part of the olive.

2024年10月5日 · Cerebellar infarcts are acute ischemic stroke subtypes caused by the occlusion of 1 of the 3 main cerebellar branches of the vertebrobasilar arterial system or the posterior circulation, namely, the superior (SCA), anterior inferior (AICA), and posterior inferior (PICA) cerebellar arteries.

The posterior inferior cerebellar artery (PICA), usually the largest branch of the VA, arises from its intradural segment approximately 10–20 mm from the origin of the BA.

2024年9月8日 · Usually LMS/Wallenberg's is caused by loss of blood flow in the posterior inferior cerebellar artery (PICA). PICA may arise from the vertebral artery (the usual case), or as a separate branch of the basilar artery.
