A comatose woman Saturday underwent an abortion that doctors and her husband said could save her life, ending a battle with anti-abortion activists that reached the Supreme Court.

A spokeswoman for North Shore University Hospital, outside New York City, said the operation on the Long Island woman was completed shortly after 9 a.m. and it went without complications."She is doing fine," hospital spokeswoman Carol Hauptmann said.

Martin Klein, 34, who had been granted temporary guardianship of his 32-year-old wife by a state Supreme Court justice, enabling him to order the abortion, said his wife was "resting comfortably" following the hourlong procedure.

He and the family's doctors had maintained the abortion would significantly increase Mrs. Klein's chances for survival.

"I've never thought of this as an abortion or anti-abortion issue," he said after the abortion was performed. "It was a question as to who would make a decision for a wife who couldn't make a decision for herself."

The decision was made by "a husband and family in unity who know her and love her," Klein said. The Upper Brookville, N.Y., couple has a 3-year-old daughter.

"It has been a satisfaction that we did win the battle, and no one else should ever have to go thorugh what we've gone through," he said.

Doctors began administering dilation drugs to Nancy Klein about 6 p.m. Friday, beginning a 12-hour preparation for the abortion shortly before Supreme Court Justice Thur-good Marshall refused to block the procedure.

Supreme Court Justice Antonin Scalia, with whom the case was finally appealed, did not act on the matter.

Nancy Klein, about 17 weeks pregnant, has been in a coma since a Dec. 13 car accident. She was given general anesthesia for the abortion, the hospital spokeswoman said.

Doctors contended an abortion was necessary to her survival and recovery, and her husband was granted guardianship by a state justice in an emotional legal battle that began Jan. 26.
