Rinkel GJ, et al. Intradural VA was identified for proximal control. Figure 1: posterior fossa vascular territories Figure 1: posterior fossa vascular territories. The fifth segment p5 starts where the PICA extends out from the fissure between the tonsil, vermis, and cerebellar hemisphere. It often happens that the bifurcation of the PICA occurs at this fifth segment; the lateral trunk will supply the tonsil and cerebral surface, while the medial trunk will supply the vermis.

    The medial branch of the posterior inferior cerebellar artery supplies the medial part of the cerebellar hemisphere and the inferior vermis, while the lateral branch supplies the inferior cerebellar surface and anastomoses with the anterior inferior and superior cerebellar arteries.

    If there is no evidence that the patient will be able to tolerate PICA sacrifice, the surgeon will need to prepare all alternatives, including direct clipping with or without bypass to preserve the PICA; additional endovascular coiling will likely be required to achieve complete aneurysm occlusion [ 7 ].

    Practical neuroangiography. The PICA itself is usually of a small caliber, and aneurysms on it with a wide neck create a difficult situation with respect to clipping the aneurysm and preserving the PICA. The Cerebrospinal fluid needs to be released slowly so the brain is relaxed, and everything must be done under a microscopic view.
