Medical Notes[]

Kayla Lindy[]

  • Diagnosis:
    • Pregnancy
    • Brain death
  • Treatment:
    • Heparin
    • Surgery

Kayla, 32, was 20 weeks pregnant with triplets as a surrogate. She had blood clots, which Addison said were getting worse despite heparin. She suggested selective reduction in order to save Kayla's life. The parents called in Vanessa for a consult because they believed Addison was wrong that it was the only option. Sam operated. The surgery went well, but Addison was still concerned. Later, Addison was paged to the hospital. A clot had moved to Kayla's lung. Addison took her into surgery to do the reduction. In surgery, her heart stopped. They were able to get her back, but five minutes passed and there were no signs of higher brain function. Since they hadn't done the reduction, she was still pregnant with triplets, but brain dead.

Sheldon spoke to her and believed she was schizophrenic. Cooper was skeptical, but when Maggie's mother came to him with additional concerns, they watched from another room while Sheldon spoke to Maggie, who talked about doing things because "Eli" wanted her to, including drowning her cat.
