Case Discussion
A 40-year-old lady with a history of lap cholecystectomy 3 days ago, had a sudden severe thunderclap-type headache and projectile vomiting and came to ER department. CT studies show recent subarachnoid haemorrhage secondary to a ruptured internal carotid artery saccular aneurysm.
The patient underwent coil embolisation of the ruptured aneurysm. Then decompressive craniotomy and haematoma evacuation were done in the next two days.
