Tennis star Serena Williams has undergone emergency treatment for a blood clot in her lungs, her representative told People.com on Wednesday.
Williams, 29, was treated at Cedars-Sinai Medical Centre in Los Angeles on Monday and remains in hospital under supervision, according to the statement from spokeswoman Nicole Chabot, dpa reported.
"Last week, Serena suffered from a pulmonary embolism, which was discovered upon her return to LA," Chabot said. "Serena underwent emergency treatment at Cedars. Doctors are continuing to monitor her situation closely to avoid additional complications."
Williams, the winner of 13 Grand Slam tournaments, was interred just hours after attending a glamorous Oscar party hosted by Elton John in Los Angeles. She had not played an official tennis match since winning Wimbledon in July due to complications from a cut in her foot that she suffered from broken glass in a restaurant shortly after that victory.
