Abstract

BACKGROUND: Giant aneurysms, comprising 3-5% of all intracranial aneurysms, pose a considerable challenge due to their heterogeneity and complex vascular anatomy. Defined as aneurysms exceeding 2.5 cm in diameter, they often develop intraluminal thrombosis. Despite advancements in neurosurgical techniques, managing giant aneurysms remains complex and highly individualized. Thrombotic giant aneurysms are particularly problematic due to their size and thrombosis potential. This case report is unique as it presents the first documented instance of recurrent artery of Heubner (RAH) infarction following surgical resection of a giant thrombotic aneurysm. CASE DESCRIPTION: A 53-year-old man with no prior systemic presented to our emergency department due to progressive left-sided weakness and slurred speech. Magnetic resonance imaging (MRI) of brain revealed a thrombotic giant intracranial aneurysm on right anterior cerebral artery (ACA). Surgical resection was performed using a right pterional craniotomy. During surgery, the aneurysm was confirmed to be completely thrombosed and was excised. Postoperatively, the patient experienced a generalized seizure and was intubated. Brain MRI revealed a new infarction in the RAH territory. Despite initial complications, the patient showed significant recovery with rehabilitation, regaining most motor functions by the 6-month follow-up. CONCLUSIONS: This case emphasizes the critical importance of comprehensive preoperative evaluation, particularly in assessing small perforating branches and collateral circulation. It highlights the challenges in managing giant aneurysms and the necessity of anticipating potential postoperative complications. This report adds valuable insights into the clinical management and surgical planning for giant aneurysms, particularly those involving the ACA and RAH.
