Brain aneurysms may develop without symptoms, making it important to pay attention to changes in how you feel. A sudden, severe headache is the most common warning sign and should never be ignored. Acting fast can make all the difference.
Each year, hospitals across our broader HCA Healthcare network provide care for approximately 12,000 patients with aneurysms and perform more than 3,000 procedures — supported by advanced tools to help deliver the best possible outcomes.
