It is most likely pregnancy induced hypertension. It occurs in patients with borderline hypertension or sometimes even in normal healthy patients when they get pregnant. Sometimes it may not present until after the delivery. If she was immediately managed then there is less risk, though I can t say anything without the proper reports. Did she have a Seizure after that? And yes complete recovery is possible if there aren t any other complications. The survival would mainly depend on how well she is able to hold up when the ventilator is removed (after stable vitals)
