[Hyponatremic-hypertensive syndrome successfully treated by endovascular therapy: A case report]
Introduction:
Hyponatremic-hypertensive syndrome (HHS) is characterized by hypertension and hyponatremia.
Case Presentation:
We report a case of HHS in a 73-year-old woman, revealed by a hyponatremia leading to status epilepticus, without initial hypertension due to hypovolemia. She was successfully treated by endovascular therapy without any long-term supplementation or anti-hypertensive medication.
Conclusion:
Physiopathology hypothesis of HHS implicate pressure natriuresis, in this case, hypertension is not initially found and we discuss other hyponatremia mechanisms.
