Although surgical treatment for mesial temporal lobe epilepsy has proven to be highly effective in controlling seizures and improving patients' quality of life, it carries potential risk to critical neurovascular structures, which can result in significant complications. With the advent of endoscopic techniques, the transorbital route has emerged as a potential alternative for mesial temporal lobe surgery.

This can lead to complications such as internal carotid artery (ICA) thrombosis and occlusion, presenting major neurosurgical challenges.

Imaging revealed a left orbital mass extending into the paranasal sinuses and intracranially. Empiric antifungal therapy was started. Pathology confirmed Rhizopus species. Despite extensive surgical debridement and antifungal therapy, the patient developed progressive severe cavernous ICA stenosis, leading to watershed territory strokes. To restore cerebral perfusion, protect from distal emboli, and prepare for potential aggressive debridement, a flow-replacing direct (superficial temporal artery-middle cerebral artery (M2)) bypass was performed, and the supraclinoid carotid was trapped. Intraoperative angiography confirmed robust flow through the bypass. The patient was discharged on antifungal therapy and aspirin.
