Management of aneurysmal subarachnoid haemorrhage

Acute paraplegia after aneurysmal subarachnoid hemorrhage: Case report of a rare complication with a 2‑year follow‑up

The current overall incidence of subarachnoid hemorrhage (SAH) is ~9/100,000 individuals/year and rupture of an intracranial aneurysm is the main cause of SAH, accounting for ~85% of cases. Only a small number of cases of paraplegia after intracranial aneurysmal SAH have so far been reported and its pathogenesis has remained to be fully elucidated. The present study reports the case of a patient with an aneurysm localized in the medial and inferior lateral wall of the C5 segment of the right internal carotid artery that was treated by coil interventional embolization. The muscle strength of both lower extremities of the patient was grade I and grade 0 before and after the operation, respectively. Lumbar and thoracic magnetic resonance imaging examinations revealed slight hematoma in the subarachnoid space below the L2 level. At two weeks after the operation, the muscle strength of both lower extremities was grade II, while the muscle strength was grade III and grade V at 30 and 60 days after the operation, respectively.
