Cerebral Microbleeds (CMBs) Exploration Of The Relationship With Ischemic Stroke

Purpose：By observing the micro brain hemorrhage and the clinical andimaging data of ischemic stroke, a risk factor for further study the microbrain hemorrhage, imaging, and to provide basis for clinical diagnosisand treatment.Method：Collection in November2012to November2013in our hospitalneurology in CMBs cases,30cases of cerebral CT, MRI, SWI, exclusionof calcification, tumor, etc., statistical CMBs in patients with risk factorsof the disease, good location, quantity, clinical signs and symptoms,auxiliary examination and prognosis related to clinical data, statisticalanalysis.Result：1.Age,hypertension,heart disease,high cholesterol,the use ofanticoagulation and antiplatelet agents, cerebral amyloid angiopathy,lacunar cerebral infarction risk factors in patients for CMBs.2.Studies have shown that CMBs is not completely asymptomatic,CMBs and number Patients with cognitive impairment and dysfunction,there is a certain correlation with the increase of number of CMBs,cognitive impairment and dysfunction in patients withprogressive.Clinical symptoms of CMBs mainly depends on the locationand number.3. CMBs lesions according to different causes in bilateral basalganglia, thalamus, namely the deep brain parenchyma area, secondly in cortex and subcortical areas, brain stem the cerebellum also havedistribution, number of deep brain tissue CMBs lesions significantly morethan the cortex.4. CMBs antiplatelet drug users than those not happen CMBsantiplatelet drug users, the detection of micro brain bleeding volumeincreased significantly.5. During the admission of these patients in hospital，26of the30CMBs patients witnessed improvement，4cases for the development ofcerebral hemorrhage,1cases died.Conclusion：1.Hypertension is an important risk factor of CMBs, blood pressurelevel is higher, the longer the duration, the more serious themicrovascular damage, the incidence of CMBs is higher, the morenumber of lesions.2.CMBs existence and development of great danger, after theoccurrence of CMBs sustainable for many years, early asymptomatic, butwith the passage of time, the number of CMBs increase gradually,increasing volume and can be further evolution of cerebralhemorrhage.CMBs size and quantity change reflects the potential smallvascular lesions own risk increases, the size or number may be assess itssecondary ICH risk reference index.3. With CMBs ischemic cerebral apoplexy patients takingantiplatelet aggregation drugs after an increased risk of brain hemorrhage.4. Head MRI SWI sequence is the most sensitive diagnostic CMBs,the most accurate imaging methods.
