Fluids Hypertension Syndromes: Migraines, Headaches, Normal ...

Fluids Hypertension Syndromes – Dr. Leonardo Izecksohn – page 164
- Whether the arterial blood has too few oxygen, the patient can suffer an ischemic brain stroke, or other
damage.
The patient with patent foramen ovale is lifelong prone to suffer the signs, symptoms and sicknesses
of the Fluids Hypertension Syndromes, more than other people without this cardiac damage.
This risk factor (patent foramen ovale) causes more migraines when added with some condition
which raise the venous blood pressure in the cardiac right atrium, which are:
- Valsalva maneuver.
- Breath with high-pressure air.
- Pulmonary arteriovenous malformation.
- Head-down positions.
These are another risk factors. Together with the patent foramen ovale, they turn to be etiologies of
migraines.
In the patients with migraines, “Massive right-to-left shunt (patent foramen ovale) appeared in
38.9% of migraine with aura and in 6.5% of migraine without aura. Migraine with aura patients identified
at least one Valsalva-provoking activities as headache trigger in 45.8%.” (Tembl J, and others).
The surgical closure of the cardiac patent foramen ovale and of the arterio-venous malformation improves
or cures most migraines with aura:
“Percutaneous transcatheter closure of patent interatrial communications results in significant amelioration
of Migraine headache in 87% of patients (complete resolution in 24% and significant improvement
in symptoms in 63%).” (Dubiel M, and others).
Similar pathophysiology occurs with the Hereditary haemorrhagic telangiectasia, which “is a genetic
disorder characterized by epistaxis, telangiectasia and visceral vascular manifestations. It is associated
with migraine with aura due to pulmonary arteriovenous malformations. Lifetime prevalence of migraine
was higher in Hereditary haemorrhagic telangiectasia patients (39.6%) than in controls
(19.8%).” (Marziniak M, and others).
XII t) Cardiac damage and hypothyroidism with and without blood shunting from right to left,
and from left to right, cause the Fluids hypertension.
“In 395 patients from the UCLA Adult Congenital Heart Disease Center,… the frequency of migraine
headaches was 52% in the right-to-left shunt group, 44% in the left-to-right, and 38% in the no shunt
group. In patients with a right-to-left shunt who underwent surgical repair, 47% had complete resolution
of migraine headaches, whereas 76% experienced >50% reduction in headache days per month.”
(Truong T, and others).
The probable pathophysiology is that the congenital cardiac damage and hypothyroidism cause unstable
supply of oxygenated blood to the brain, with occasional hypoxia (low O2), sometimes added
with the accumulation of carbonic gas (CO2). The ischemia and/or the excess of carbonic gas causes
the brain's vascular dilatation, the fluids’ pressures rises and downs, auras and migraines.
XII u) Cranial (cerebral) venous sinus thrombosis and stenosis, and Jugular vein thrombosis
cause the Fluids Hypertension Syndromes:
The Cranial (cerebral) venous (dural) sinus thrombosis and the Jugular vein thrombosis are caused by
cranial trauma, meningitis, and other etiologies. The venous sinus thrombosis can recover but it remains
a sinus stenosis, verifiable by a magnetic resonance venography. The stenosis chronically difficult
the venous blood return from the brain and eyes, causing chronic increased venous pressure and
excessive fluids’ exudation. They can cause the Cerebrospinal Fluid’s and Ocular Hypertension syndromes,
with respective migraines and variants:
“Of patients with migraine, 6.7% had bilateral transverse sinus stenosis; 67.8% of these patients had
idiopathic intracranial hypertension without papilledema”. (Bono F, and others).
“Among the 198 patients with chronic tension-type headache who underwent magnetic resonance
venography, 18 (9%) had bilateral transverse sinus stenosis. Thirteen of these 18 patients with bilateral
transverse sinus stenosis underwent lumbar puncture, and nine (69.2%) had idiopathic intracranial hypertension
without papilledema.”(Bono F, and others).
