Abstract
Background: Anterior inferior cerebellar artery (AICA) aneurysms are relatively rare in clinical practice, accounting for <1% of all intracranial arteries. After the diagnosis and location are confirmed by angiography, magnetic resonance, and other imaging examinations, interventional, or surgical treatment is often used, but some complex aneurysms require reconstructive surgery.Case Description: An 8-year-old male child was admitted to the hospital due to sudden disturbance of consciousness for 2 weeks. The head CT showed hematocele in the ventricular system with subarachnoid hemorrhage in the basilar cistern and annular cistern. On admission, he was conscious, answered correctly, had a soft neck, limb muscle strength was normal, and had no cranial nerves or nervous system abnormalities. A preoperative examination showed the right side of the anterior distal arteries class under the circular wide neck aneurysm, the distal anterior inferior cerebellar artery supplying a wide range of blood to the cerebellum, the ipsilateral posterior inferior cerebellar artery absent, and the aneurysm close to the VII, VIII nerves. The aneurysm was successfully treated by aneurysm resection and intracranial artery anastomosis in situ of a2 AICA-a2 AICA.Conclusions: AICA aneurysms are relatively rare; in this case, a complex wide-necked aneurysm was successfully treated by aneurysm resection and anastomosis in situ of a2 AICA-a2 AICA. This case can provide a reference for the surgical treatment of complex anterior cerebellar aneurysms.

Anterior inferior cerebellar artery (AICA) aneurysms are rare clinically, accounting for
After dissociating the proximal and distal vessels of the AICA, end-to-end intracranial vascular anastomosis of a2 AICA-a2 AICA was performed in situ, and intraoperative fluorescence angiography was performed to confirm the patency of the anastomotic vessels (Figures 3B,C)
When the ipsilateral posterior inferior cerebellar artery (PICA) and superior cerebellar artery (SCA) is hypoplasia or tiny, when AICA is the mutation of PICA, or when you cannot be sure that variations in the course of the internal auditory artery (IAA) arise from the distal AICA, pure isolated aneurysm or occlusion of the anterior artery can produce a wide range of cerebral infarction and severe neurological dysfunction
