Attorneys for Adriana DeSilva's family say they may sue a Boca Raton plastic surgeon after the Harrison woman died following a series of cosmetic surgeries in April.

Lawyer Daniel Harwin said Saturday he's waiting on autopsy results to find out the exact cause of death for the 39-year-old mother of two, who worked as a home health aide. The Palm Beach County Medical Examiner's office is performing the official autopsy, and Harwin said he also has hired an independent forensic pathologist.

DeSilva underwent a breast augmentation, tummy tuck and neck liposuction on April 5 as "a present that she was going to give herself for her birthday and for Mother's Day," DeSilva's 14-year-old daughter, Kerolayne Stuwer, told reporters at a news conference in Boca Raton on Thursday.

DeSilva was released by Dr. Daniel M. Zeichner 90 minutes after the four surgical procedures, attorneys for the family said. She complained of pain the next day, and two days after the surgeries she suffered a stroke, which sent her into a coma before she died.

"It's been hard," Stuwer said, fighting back tears. Stuwer told reporters she lamented the fact that her mother died "when I wasn't there to hold her hand for the last few seconds."

Stuwer and her younger brother have been pulled out of school and were preparing for a Sunday flight to Brazil, where Harwin said they'll live with their maternal grandmother.

"They don't really have a support system left in New York," Harwin said.

At the time of the surgery, DeSilva was caring for an elderly Alzheimer's patient while taking night classes to become a registered nurse, he said.

Messages left Saturday afternoon with Zeichner were not immediately returned, and the Palm Beach County Medical Examiner's office was closed for the weekend.

Harwin, who was retained by a family member who has power of attorney for DeSilva's children, said any lawsuit would be filed in Palm Beach County Court.

Attorney Andrew Kessler, another Florida lawyer retained by DeSilva's family as co-counsel, said he has "great concerns about the fact that Adriana DeSilva underwent so many procedures at once, and did so at an outpatient surgery center."
