Welcome to the ePoster Viewing Panel of AICOG 2025

Objective Delta hypertension refers to a significant increase (?15%) in mean arterial pressure (MAP) after 32 weeks of gestation compared to the average mid-pregnancy MAP , which can signify endothelial dysfunction leading to critical end-organ damage even if the blood pressure remains below the traditional threshold of 140/90 mmHg. We document a case of post partum eclampsia occurring within normotensive range of BP. Case Summary 23 year female, primigravida with 40 weeks of gestation with thrombocytopenia in labor was referred for high risk obstetric management. Patient had no prior medical history, with regular ANC visits. BP readings between 16-28 weeks of gestation recorded as 90/60mmhg-100/60mmhg. Patient delivered a low birth weight (2.1 kg) female baby vaginally. Post delivery patient developed episiotomy site hematoma which was drained under anesthesia. Post operatively, BP ranged from 130/80-134/86mmmhg. Five hours after the procedure, patient suffered from one episode of generalized tonic-clonic seizure. After stabilization, blood and radiological investigations were sent. Serum electrolytes, hemogram, liver function test, renal function tests, CECT and MRI brain, Fundoscopy, USG abdomen and 2D echocardiography were all within normal limits. By day-5 PNC patient BP ranged from 100/60-90/60 mmHg, suffered from no further seizure episodes, and was later discharged uneventfully. Discussion We have documented the occurrence of critical end-organ damage in the form of thrombocytopenia, low birth weight baby (2.1kg) and seizure within the normotensive threshold. Recent evidence highlights that delta hypertension maybe a reliable indicator of manifestations of hypertensive vascular insult even if blood pressure readings remain below the standard diagnostic thresholds. Conclusion Delta hypertension emphasizes the importance of longitudinal monitoring of blood pressure throughout pregnancy allowing clinicians to identify at-risk patients earlier, even if the patient falls within the normotensive range.
