Abdominal aortic aneurysm
Actress Lucille Ball died April 26, 1989 from an abdominal aortic aneurysm. At the time of her death, she was in Cedars-Sinai Medical Center recovering from emergency surgery performed just six days earlier because of a dissecting aortic aneurysm near her heart. Ball was at increased risk, as she had been a heavy smoker for decades.

Lucille was also "hopelessly entangled" with her kids until her death on November 4, 1986, as Debra reported in a 2006 newspaper article she wrote about her mother's case.
