High blood
pressure is prevalent in about 10% of the population. Over 80% of these patients
suffer from the so-called essential hypertension, having no clear etiology of
their disease. Longstanding
hypertension causes arteriosclerosis, stroke and heart attack. Therefore many
patients depend on live long medication. It is
known that the central nervous system plays a major role in regulating the
blood pressure. Newest findings frequently show in patients with arterial
hypertension contacts between vessels and cranial nerves IX & X like
neurovascular compression at the ventrolateral medulla. These
contacts were removed in a certain number of patients - microvascular decompression
- and led not only to a lowering of the blood pressure but also in some cases
to complete normalization. We can therefore assume a association between
neurovascular compression and the essential hypertension. This
association is being investigated in a cooperative scientific study of the
department of neurosurgery and the medical clinic IV - nephrology of the
University Erlangen-Nuremberg. A neurovascular compression at the brain stem
in arterial hypertension can be easily proven by high resolution MRI. In
selected cases resistant to medical therapy microvascular compression can be
taken into consideration. |
