34 Cases Of Hemorrhagic Cerebral Infarction Analysis Of Clinical Imaging

Objective:The hemorrhagic cerebral infarction (HI) to analyze the imaging features.Methods:The cases from March 2007 to February 2009 during the Second Hospital of Dalian Medical University Department of Neurology,the new hospital 220 cases of cerebral infarction patients, which found that for 34 cases of hemorrhagic cerebral infarction. All the selected cases are in line with the Chinese Medical Association in 1995 the Fourth National Symposium on cerebrovascular disease,through the "diagnosis of cere- brovascular diseases of various elements of the" standard, have been con- sidered by the brain CT and (or) MRI scan proved to cerebral hemor- rhage.Retrospective analysis of 34 cases of HI patients with a history, clinical manifestations, brain CT,MRI examination,clinical efficacy, such as information and analysis of its short-term prognosis,HI occurred, bleeding type,infarct size,a good site, blood supply, video school performance,X2 test applied statistics. Hemorrhagic cerebral infarction on imaging features for analysis.Results:1.34 cases of HI in this group of patients with cerebral infarction in the same period accounted for 15.45%, of which 16 cases of male, female 18 cases, the age distribution in the 45~86 years old, the average age of 68.09±10.41.2.34 cases of HI in which 26 cases of cerebral embolism (76.47%), seven cases of cerebral thrombosis (20.58%),1 cases of lacunar infarction (2.94%), cardiogenic cerebral embolism in 22 cases (64.71%),history of atrial fibrillation 14 cases (41.18%), 24 cases of large infarction (70.59%). 3. HI cerebral infarction occurred in 1 week after 11 cases (32.35%), the first two weeks in 17 cases (50.0%), and three weeks after the first six cases (17.65%).4.5 cases of patients admitted to the first CT examination that is diagnosed as HI, more than 29 cases are reviewed after the diagnosis of cerebral CT,MRI secondary hemorrhage was found. 30 cases of CT prompted HI, there is no CT review of four cases of hemorrhage secondary line MRI discovered bleeding, nine cases of MRI prompted HI.5. Hematoma type 12 cases (35.29%), both in patients with cerebral embolism, cerebral infarction occurred in 1 week after the 9 cases (75%), mass effect,11 cases (91.66%). 22 cases of non-hematoma-type (64.71%), cerebral infarction occurred in the first two weeks and after 20 cases (90%), six cases of mass effect (27.27%). Evaluation of short-term prognosis, 12 cases of hematoma-type, five cases of effective and ineffective in 7 cases, 41.67% efficient, non-hematoma in 22 cases of type, 18 cases of effective and ineffective in 4 patients, 81.82% efficient.6. Hemorrhagic fociincerebral cortex is located in 23 cases (67.65%), 31 cases of internal carotid artery system at the blood supply area (91.17%), three cases of vertebral-basilar artery system at the blood supply zones, middle cerebral artery infarction in 24 patients(70.58%).7.HI performance in the original CT infarct appeared punctate, patchy, or strip of high-density mass shadow; MRI lesions in acute stage of the performance of short T1,short T2 signal;sub-acute stage of disease,there are short T1,long T2 signal.Conclusion:1.Embolic occlusion of vascular recanalization migration,the establish- ment of collateral circulation is closely related to the occurrence of HI,for cardiogenic cerebral embolism and a large area of cerebral infarction, irrespective of whether the clinical symptoms increased attention should be within two weeks after cerebral infarction review of imaging.2.Hematoma type found in the cerebral embolism, non-hematoma-type and the establishment of collateral circulation; HI occurs sooner, the more serious clinical symptoms,the worse the prognosis;hematoma hematoma type than that of non-timing-based earlytype than nonhematoma hematoma type poor prognosis.3.Prone to large-scale cerebral HI,the cortex than the subcortical infarcttion infarction complicated easier to HI, cerebral artery infarction often occurred in HI, for such patients should be reviewed brain CT, MRI.4.CT, MRI clinical diagnosis of HI is the most important non-invasive examination, the acute phase in CT is more sensitive, CT remains the first choice for the acute phase, subacute phase MRI is more advantage than CT. CT, MRI of hemorrhagic cerebral infarction for clinical diagnosis has an important guiding value.
