A 57-year-old man presented with sudden-onset consciousness disturbance. He had a 10-year history of a subarachnoid hemorrhage(SAH)caused by a ruptured aneurysm in the right middle cerebral artery, and had undergone aneurysmal clipping. He could perform all his daily life activities independently. ⋯ We initially performed superficial temporal artery(STA)-ACA anastomosis and secondary internal trapping with detachable coils in the operating room. Postoperative DSA revealed complete obliteration of the dissection and parent artery. Endovascular treatment with STA-ACA bypass is a safe and effective alternative for the treatment of ACA dissection.

Review Case Reports
[Contralateral suboccipital approach for clipping of an unruptured vertebral artery-posterior inferior cerebellar artery aneurysm].
Numerous approaches have been used to access aneurysms of the vertebral artery(VA)-posterior inferior cerebellar artery(PICA)complex for microsurgical clipping. Here, we report the case of a patient with an unruptured aneurysm of the left VA-PICA complex that was successfully treated using a contralateral suboccipital approach. Computed tomography angiography demonstrated a small saccular aneurysm arising from the lateral aspect of the left V4 segment just distal to the PICA origin. ⋯ After surgery, slight dysphagia and hoarseness appeared, but dysphagia disappeared within several days and hoarseness disappeared within 5 months. VA-PICA aneurysms can vary in their relationship to cranial nerves, brainstem, and bones of the skull base. Neurosurgeons should consider using a contralateral approach for certain aneurysms arising from a tortuous VA that has crossed the midline.
