11 月13日 终于找到另一股在我家害我的势力
昨天,这些人折腾了一天,白天,晚上皮啦啦,也不知道谁把谁杀了,谁把谁带走了。
反正我先生和孩子被绑架了,就不知道是不是已经遇害了。我本来是打算睡觉的,但他
们头上,地下装电磁波攻击器,让我几乎窒息。虽然我没倒下,但其实他们在我身上扎
的毒针已经蔓延,我能感觉到我的呼吸有窒息的感觉。我想我对他们已经非常仁慈了,
但他们不依不饶地攻击我,欲置我于死地,让我非常生气,特别是肆意伤害我家里的人
,绑架我先生和孩子,而且有许许多多无辜的生命毁于他们之手,有必要把他们曝光。
当然我还没分析这里边是那几个人具体攻击我,伤害我的,但他们显然都是一伙的。鉴
于他们伤害我的头部,胸部 和胃部,我就把这几部分的医生都曝光,受害者慢慢去调
查,追查他们吧。

asymptomatic carotid stenosis, although some data support surgery over drug,
the benefit is small and depend on life expectancy and surgical skills.
For this patient, her syncope is not caused by carotid stenosis. I always

Surgery/stenting for asymptomatic carotid artery stenosis over 70% is still
controversial.
The key is what caused syncope?
Left carotid artery stenosis usually is not the cause of syncope. Basilar
artery stenosis, however, could induce brain stem ischemia and cause vertigo
and syncope. I did not see basilar artery flow direction on the U/S. If retrograde, a
subclavian steal could cause the syncope.
So you may fix the carotid artery stenosis but not the syncope. The patient

First of all, medicine is the science.

unilateral lobectomy are fully awake.
2. Asymptomatic carotid stenosis does not necessorily need surgical
intervention. I have seen patients with bilateral carotid occlusion without
any stroke or TIA.
Second, medicine is also the art.

Carotid stenosis and renal artery stenosis at 60-70% is not critical. I have
seen a lot of patients follow even more severe stenosis.
Your father eventually needs diagnostic angiogram with aortic and bilateral
lower extremities run-off to evaluate for occlusion. Or he should at least
get arterial dopplers to check the waveforms and ABI (ankle brachial index)
first.

It is called occulo-stenosis reflex which is used in coronary angioplasty“

I guess the stenosis of intracranial artery is due to atherosclerosis or
vessel spasm,
if the former, and there are dizziness, syncope, falls, and recovered in 24
hours, that's TIA. Aspirin is a must, check lipid panel, fasting blood sugar
, and further treatment depends on the location of the stenosis, severity
and other brain diseases.
if vessel spasm, some calcium channel blocker may help, and gingko
derivative meds works in some people.

CT may not be the best, but it in this case detects lots of stenosis.
Therefore, angiogram is necessary in the next step management. And, bypass
is the only choice if the angiogram suggests multiple severe stenosis too.
The lesions appear complicated. Follow the local doctor's suggestions and
find a good hopsital in cardiology if possible. Bypass belongs to open heart
surgery.

Heart failure (HF) is a clinical syndrome caused by the inability of the
heart to pump sufficient blood to meet the metabolic needs of the body.
Heart failure can result from any disorder that reduces ventricular filling
