In his account, Santorum recalls that during the debate over the proposed veto override an opponent charged that he could not understand the roiling emotions of women who had been through the experience.
Only a week or so later, Santorum said, he understood.
Karen was in her 19th week of pregnancy. Husband and wife were in a suburban Virginia office for a routine sonogram when a radiologist told them that the fetus Karen was carrying had a fatal defect and was going to die.
After consulting with specialists, who offered several options including abortion, the Santorums decided on long-shot intrauterine surgery to correct an obstruction of the urinary tract called posterior urethral valve syndrome.
A few days later, rare ``bladder shunt'' surgery was performed at Pennsylvania Hospital in Philadelphia. The incision in the womb carried a high risk of infection.
Two days later, at home in the Pittsburgh suburb of Verona, Karen Santorum became feverish. Her Philadelphia doctors instructed her to hurry to Pittsburgh's Magee-Women's Hospital, which has a unit specializing in high-risk pregnancies.
After examining Karen, who was nearly incoherent with a 105-degree fever, a doctor at Magee led Santorum into the hallway outside her room and said that she had an intrauterine infection and some type of medical intervention was necessary. Unless the source of the infection, the fetus, was removed from Karen's body, she would likely die.
At minimum, the doctor said, Karen had to be given antibiotics intravenously or she might go into septic shock and die.
The Santorums were at a crossroads.
Once they agreed to use antibiotics, they believed they were committing to delivery of the fetus, which they knew would most likely not survive outside the womb.
