Interventions
- Omental Biopsy — PROCEDUREThe surgeon and clinical care team will conduct the c-section to deliver the baby and the placenta as clinically indicated. After delivery, during the closing procedures, the surgeon will indicate a time for a participating Ob/Gyn physician on the study team to collect the omental bio-specimen. Omentum is frequently excised or removed for clinical reasons during surgical procedures. Omentum has small blood vessels within it that have been used for evaluation of vascular functional changes in research. The investigators wish to isolate one to three vessels of 5 to 7 cm length. The surgeon will then close and the clinical care team will resume their standard of care activities.
Study Details
The investigators will collect omental tissue (research surgical excision) and placental tissue (standard of care clinical delivery) from both preeclamptic and non-preeclamptic women during their c-section and use these samples to study the blood vessels, specifically the expression/activation of the AT2R.
