An autopsy of rapper Kanye West's mother has failed to turn up an official cause of death, E! Online reports. A report by the Los Angeles coroner said that Donda West suffered from coronary disease as well as post-operative problems from liposuction and breast-reduction surgery, but that "the final manner of death could not be determined."
The 58-year-old former professor weighed 188 pounds at 5-foot-2, and had major blockages of two arteries, according to the report. A doctor who performed the cosmetic surgeries in November had come under scrutiny for going ahead with the elective procedures despite his patient's health issues.
