The exact cause of death for rapper Kanye West's mother is "unclear", according to the Los Angeles County Coroner.
In a 17-page final autopsy report, the coroner's office attributed the death of 58-year-old Donda West to coronary artery disease and a number of factors related to her cosmetic surgery the day before.
However, the report said that there was no sign of "surgical or anesthetic misadventure".
Donda West died on 10 November last year after she was found in an unresponsive state at her home, a day after undergoing a cosmetic surgery procedure.
A preliminary report had suggested that she died from possible complications after the surgical procedures.
The final autopsy report, which is inconclusive, said that West "died from some pre-existing coronary artery disease and multiple post-operative factors following surgery".
"Based on the history and available information, as currently known, the manner of death could not be determined," the report said.
