Each year,half a million people die from brain aneurysms(动脉瘤)—when a blood vessel bursts in the brain.An aneurysm is a bulge in a blood vessel that can burst.If that happens in the brain,it can be deadly.For survivors,physical disabilities are often severe.They may include memory problems,loss of balance,trouble speaking and even blindness.But new technologies are increasing survival rates and reducing disabilities.
Beaumont Bacon is a survivor who makes light of her experience because she is a comedian.She uses humor to make others laugh.Now she's working on a new show.Michael Alexander is her doctor.He operated on Beaumont Bacon after her attack.“She had bleeding in the frontal area of her brain,so right above the eyes.The part that was in the brain was about maybe the size of an egg.So,that's a fairly large bleed.”
Ms.Bacon had a better chance at survival than most people because of Dr.Alexander.He directs the Neurovascular Center in Los Angeles.The center offers new technologies that include placing a catheter(导管) into an aneurysm,then threading wires to promote blood clots(血栓).This technique reduces the chances of another burst blood vessel.“You don't have to open up the skull or open up the brain to do surgery.It's all done from inside the blood vessels.So it reduces the amount of blood loss,and the recovery is much faster.”
For Beaumont Bacon's recovery,the hospital worked to prevent problems commonly found in patients with a burst aneurysm.The problems include brain swelling that can shut down blood vessels.She spent a month in a coma(昏迷)—unable to communicate with doctors,friends and loved ones.But with a year of treatment,she recovered.Now,she is making people laugh.
