Arterial compression of the retro-olivary sulcus of the medulla in essential hypertension: a multivariate analysis

Abstract

In this retrospective study of subjects with EHTN and normotensive controls that had undergone magnetic resonance imaging of the posterior fossa, AC of the ROS on either side of the medulla is a significant independent risk factor in EHTN. Further studies are required to determine whether this is true for the general population of patients with neurogenically mediated EHTN.

Atlas vertebra realignment and achievement of arterial pressure goal in hypertensive patients: a pilot study

“…Coffee et al 9 reviewed MR images and demonstrated a significant association between pulsatile arterial compression of the ventrolateral medulla and presence of hypertension. They concluded that subjects with hypertension should have an evaluation of their posterior fossa for evidence of anatomic abnormalities.…”

“…They concluded that subjects with hypertension should have an evaluation of their posterior fossa for evidence of anatomic abnormalities. 9 In fact, data linking changes in Atlas anatomy and posterior fossa circulatory changes associated with hypertension date back more than 40 years and are reviewed by Reis. 4 The mechanism as to why this improvement in BP occurs is unknown and cannot be determined by this study.…”

“…Furthermore, two other studies using MR imaging techniques also demonstrated a significant association between compression of the vertebral artery and changes in the posterior fossa of hypertensive but not normotensive individuals. 9,10 Thus, alterations in Atlas anatomy can generate changes in the vertebral circulation that may be associated with elevated levels of BP.…”

Observations of Changes of Blood Pressure Before and after Neurosurgical Decompression in Hypertensive Patients with Different Types of Neurovascular Compression of Brain Stem

“…Around thirty years ago it was reported first time that NVPC of the RVLM also can be behind of the arterial HT. The posterior inferior cerebellar artery (PICA) and/or the vertebral artery (VA) can compress the root-entry zone of cranial nerves IX and X and/or the C1 neurons containing the retro-olivary sulcus near to the root-entry zone on the left side [5,10,11,12,13]. …”

The role of the sympathetic nervous system in the pathomechanism and the therapy of hypertension

“…About forty years ago it was reported for first time by Jannetta and his colleagues that NVPC of the RVLM also can be behind arterial HT. The PICA and/or the VA can compress the root-entry zone of cranial nerves IX and X and/or the C1 neurons containing the retro-olivary sulcus near to the root-entry zone on the left side ( Figure 4) (74,75,76,77,78).…”
