Left untreated, a cerebellar stroke can be life-threatening. The complexities involved in the surgical approach to the PICA. PICA has the most complex and variable course among all arteries of the posterior circulation. 1 3 Surgery for these aneurysms is extremely challenging. According to a 2015 review, they account for less than 10 percent of all strokes. Vertebral artery- posterior inferior cerebellar artery (VA-PICA) aneurysms constitute 0.5-3 of all intracranial aneurysms. The vessels that reach this part of the brain include:Ī cerebellar stroke is a rare condition. A blood clot in any of these vessels can cause a stroke. There are a number of blood vessels that feed the cerebellum.

Blockage of the posterior inferior cerebellar artery can result in a type of stroke called lateral medullary syndrome. It is one of the three main arteries that supply blood to the cerebellum, a part of the brain. Each side controls coordination and movement for the corresponding side of your body. The posterior inferior cerebellar artery ( PICA) is the largest branch of the vertebral artery. It’s located at the back of your brain, at the bottom. The cerebellum is the portion of the brain that controls movement and maintains balance. It’s also referred to as cerebellar stroke syndrome. This type of stroke typically affects only one side or section of the cerebellum. It occurs when a blood vessel is blocked or bleeding, causing complete interruption to a portion of the cerebellum. From the results of the present study, it is evident that there was a significant PICA emergence from the superior part of the vertebral artery and that the double origin of non-hypoplastic trunks was also found in some patients the latter is associated with a greater chance of aneurysms and other additional complications.A cerebellar stroke is one of the less common types of strokes. The clinical implication of this knowledge and consensus is obtaining the best surgical strategies for clipping aneurysms and, in addition, the best choices for occlusion of the vessel affected if the territory of the main vessel has an adequate collateral circulation. The results obtained in the present study indicated the great importance of the studies and reviews on the different topographies of PICA these studies and reviews expand the knowledge and consensus on the characteristics and implications of PICA?s variations. The double origins of non-hypoplastic PICAs were found in 17% (n = 4) of patients. Moreover, variations such as hypoplastic arteries, missing trunks on one side and double or triple trunks, different emergence sites, significant PICA emergence from the superior part of the vertebral artery (59% of the trunks), and asymmetries between the right and left sides were recorded. Some striking variations were found, such as the absence of the left vertebral artery in one of the brains and the emergence of any PICA in another two brains studied. The present study analyzed the different variations of the PICA?s first two segments, the anterior medullary and lateral medullary segments, regarding the number of trunks, their emergency site, and the presence or absence of hypoplasia of this artery, through microsurgical dissection of 23 fresh cadaver brains. Twelve lesions arose from the left PICA, nine were right-sided, and all were. Seventeen of these lesions originated from the PICA-vertebral junction, and four arose from distal PICA branching sites. To study the operative approaches for posterior inferior cerebellar artery (PICA) aneurysms or understanding the different pathologies that can affect this artery, and to present detailed knowledge of this artery?s anatomy. The clinical and anatomical features of 21 surgically treated saccular aneurysms of the posterior inferior cerebellar artery (PICA) are analyzed.
