A Salt Lake County mother filed a lawsuit on Monday against two doctors and several medical institutions in relation to the death of her 15-year-old son in April 2006.

Michael Vasquez died after having his tonsils and adenoids removed, according to documents filed in 3rd District Court on Monday. He bled profusely and died of lack of oxygen to the brain within one week of the surgery.

Sophia Vasquez alleges in the lawsuit that the doctors and medical institutions were negligent in treating her son. They failed to treat him for the bleeding, failed to provide timely transport and failed to provide blood transfusions that may have saved his life, according to the filing.

The excessive bleeding started after the boy was released from Primary Children's Medical Center following his surgery.

Defendants in the case are Pioneer Valley Hospital, Gold Cross Ambulance, the state of Utah, Primary Children's Medical Center, University of Utah Hospitals and Clinics and doctors Matthew Feil and J.S. Roger Jones.

Vasquez has demanded a jury trial and hopes general and special damages will be proven.
