Final answer:
The most common cause of pre-eclampsia mortality is hypertensive disorders, which can lead to serious complications such as eclampsia, stroke, and organ failure.
Step-by-step explanation:
The most common cause of pre-eclampsia mortality is hypertensive disorders. Pre-eclampsia is a pregnancy complication characterized by high blood pressure and signs of damage to another organ system, most often the liver and kidneys. It can lead to serious, even fatal, complications for both mother and baby. Other potential severe complications include placental abruption, thromboembolism, and renal failure, but these are less common than hypertensive-related issues. Hypertensive disorders in pregnancy can result in consequences such as eclampsia, stroke, and other organ failure, which are primary contributors to maternal mortality.
