WebThe AICA can arise from a common trunk AICA-PICA. It can be sometimes doubled and rarely absent. The PICA also can arise from a common trunk AICA-PICA and sometimes from the extradural segment of the vertebral artery. Concerning the venous organization, we distinguish the superficial and deep veins. The superficial veins drain the cerebellar ... WebPICA typically arises as a single trunk from the distal, intracranial VA, but it does not do so in all cases. Variant PICA origins (e.g., a relatively common origin in the extracranial VA) and other PICA anomalies are associated with an increased likelihood of intracranial aneurysms elsewhere in the cerebral circulation.

WebJan 1, 2014 · The size of AICA is usually in inverse proportion to that of PICA: when AICA is poorly developed, PICA can form a common trunk with AICA; conversely, a well-developed PICA may cover the area normally supplied by AICA. AICA exhibits several variations. A single AICA present on each side is usually found in most cases.
