Do you mean "dural ectasia"? Dural ectasia is present in more than 60 percent of people who have Marfan syndrome. Do you have Marfan syndrome? My knowledge with Marfan syndrome is very limited, and it's important for people suffering Marfan syndrom get an experienced personal doctor, people with Marfan syndrom all have individualized symptoms, a personal doctor will understand your condition better than anyone else. Mayo clinic has a specialized Marfan Syndrome Clinic in Minnesota, if you feel interested you can search info about this clinic. Wish you good luck.
