Microsurgical decompression for severe arterial hypertension caused by neurovascular compression showed mixed long-term results. While some patients achieved sustained normotension, others experienced complications, highlighting the need for further research.

Area of Science:

  • Neurosurgery
  • Cardiology
  • Nephrology

Background:

  • Severe arterial hypertension can be linked to neurovascular compression.
  • Eight patients with intractable hypertension and neurovascular compression underwent surgery.

Purpose of the Study:

  • To evaluate the long-term outcomes of microsurgical decompression for arterial hypertension.
  • To assess blood pressure control and secondary organ damage post-surgery.

Main Methods:

  • Prospective study of 8 patients with a mean follow-up of 3.5 years.
  • Regular monitoring of blood pressure and antihypertensive medication.
  • Echocardiography, fundoscopy, and renal function tests to assess organ damage.

Main Results:

  • Three patients remained normotensive with reduced medication.
  • Two patients required increased medication but had lower blood pressure than pre-surgery.
  • Three patients suffered severe cardiovascular and renal complications, including fatal events.

Conclusions:

  • Microsurgical decompression is a viable option for a subset of hypertension patients with neurovascular compression.
  • The role of looping arteries in non-improving cases requires further investigation.
  • Prospective studies are needed to clarify the pathophysiology of neurovascular abnormalities and hypertension.
