CharcotâBouchard aneurysms are aneurysms of the brain vasculature which occur in small blood vessels (less than 300 micrometre diameter). CharcotâBouchard aneurysms are most often located in the lenticulostriate vessels of the basal ganglia and are associated with chronic hypertension. [1] CharcotâBouchard aneurysms are a common cause of cerebral hemorrhage. CharcotâBouchard aneurysm rupture might be linked to senile plaque formation in the Alzheimer's disease. [2]
Retinal microaneurysms are seen in conditions like diabetic retinopathy, [3]: 498 HIV related retinal microangiopathy, [3]: 467 sickle cell retinopathy, [3]: 533 idiopathic macular telangiectasia [3]: 601 etc. In diabetic retinopathy, due to breakdown in bloodâretinal barrier, microaneurysms may leak plasma constituents into the retina, or it may thrombose. [3]: 498
If a CharcotâBouchard aneurysm ruptures, it will lead to an intracerebral hemorrhage, which can cause hemorrhagic stroke, typically experienced as a sudden focal paralysis or loss of sensation. [1]
CharcotâBouchard aneurysms are aneurysms in the small penetrating blood vessels of the brain. They are associated with hypertension. The common artery involved is the lenticulostriate branch of the middle cerebral artery. Common locations of hypertensive hemorrhages include the putamen, caudate, thalamus, pons, and cerebellum. [ citation needed]
As with any aneurysm, once formed they have a tendency to expand and eventually rupture, in keeping with the Law of Laplace. [4] [5]
Usually not detected by CT angiography. [5] Retinal microaneurysms can be diagnosed using ophthalmoscopy, fundus photography, FFA, and OCT. [6]
CharcotâBouchard aneurysms are named for the French physicians Jean-Martin Charcot and Charles-Joseph Bouchard. [7] [8] Bouchard discovered these aneurysms during his doctoral research under Charcot. [9]
