Need a better strategy to find strategic infarcts?
Strategic infarcts are infarcts located in structures directly related to cognition.
Damage to these structures results in dementia without any other significant volume loss.
These infarcts are like a ninja. Just one shot right to the heart to take it down.
Just one infarct in one of these important structures can cause dementia like a shot to the heart.
So which structures are these?
Well, there are many structures that have been implicated in strategic infarct dementia.
But the main ones are hippocampus, internal capsule (ant & genu), thalamus (paramedian) & caudate.
I remember this w/the mnemonic:
One HIT CAUses dementia
H = Hippocampus
I = Internal Capsule
T = Thalamus
CAUD = Caudate
Now you can be a ninja looking for these ninja infarcts!
Dolichoectasia, when arteries balloon or elongate, can compress cranial nerves & cause syndromes not responsive to MICROvascular decompression (i.e., padding), but MACROvascular decompression (i.e., moving artery off nerve) works. But you need a rig that pulls forward/inward w/ adjustable tension. Here’s how…
Feeling stuck in the middle when it comes to middle cerebral artery infarcts?
It may be only one vessel, but you can get many different infarct patterns & symptoms depending on where it’s occluded!
Here’s what you NEED to know:
FIVE MAIN INFARCT PATTERNS
1. Occlusion of the MCA stem or proximal M1 segment before the lenticulostriate origin
--Involves deep & superficial territories
--Weakness is usually severe. Face, arm, & leg are similarly affected
--Remember: Whole MCA occlusion = Whole hemiparesis
2. Lenticulostriate artery (LSA) Infarcts
--Involves deep territory
--Hemiparesis, hemisensory, occasional aphasia & visual hallucinations
--Remember: LSA stands for Limp (weakness), Sensory deficits, & occasional Aphasia
3. Distal M1 segment occlusion after the LSA origin
--Involves whole superficial MCA territory
--Sometimes weakness in face & arm > leg (brachiofacial hemiparesis)
--Remember: Distal MCA occlusion can somewhat spare the DISTAL most extremity (leg)
4. Superior Division occlusion
--Uncommon bc superior trunk is so short
--Involves frontal & anterior parietal lobe, including pre- & post-central gyri
--Prominent faciobrachial hemiparesis w/matching hemisensory
--Rarely visual field defect
--Remember: Superior is more = more pronounced motor deficits than inferior division
5. Inferior Division occlusion
--Involves temporal gyri & superior/inferior parietal lobule
--Facial brachial weakness is more mild than w/superior division
--Common visual field defect (homonymous hemianopia or upper quadrantopia)
--Remember: Inferior is less, so motor deficits are less pronounced
--Remember: Inferior starts w/the letter “I” = “eye” so visual field deficits
Hopefully now your reports won’t middling when it comes to middle cerebral artery infarcts!

با بحرانِ بعدی میتونم بزنم زیر تمامِ میزهای جهان و جلوی بازشدن هیچ گرهای رو نگیرم. گرههایی که تا قبل از این با دندون نگهشون داشته بودم.
کیلومترها از خودم و هرآنچه میخواستم دورم، اما دیگر هیچ اهمیتی ندارد. پوچی همهچیز نمایان شده و این روزها صرفا با جدیتی غمآلود و غیرضروری ادامه میدهم. تا کجا؟ این هم اهمیتی ندارد...
