cerebralhemorrhage腦出血

cerebralhemorrhage是指原發(fā)性非外傷性腦實(shí)質(zhì)內(nèi)出血80%以上由高血壓性腦內(nèi)細(xì)小動(dòng)脈病變引起,固又稱高血壓動(dòng)脈硬化性腦出血發(fā)病率高，占全部腦卒中20％—30％Hypertensionisthemostcommonunderlyingcauseofnontraumaticintracerebralhemorrhage病理

pathology多為腦動(dòng)脈深穿支破裂所致豆紋動(dòng)脈最為常見，次為丘腦穿通動(dòng)脈、基底動(dòng)脈旁中央支多發(fā)于大腦半球基底核區(qū)，次為腦葉、腦干和小腦Mosthypertensivehemorrhagesoriginateincertainareasofpredilection,correspondingtolong,narrow,penetratingarterialbranches.Theseincludethecaudateandputaminalbranchesofthemiddlecerebralarteies(42%);branchesofthebasilararterysupplyingthepons(16%);thalamicbranchesoftheposteriorcerebralarteries(15%);branchesofthesuperiorcerebellararteriessupplyingthedentatenucleiandthedeepwhitematterofthecerbellum(12%);andsomewhitematterbranchesofthecerebralarteries(10%).出血可直接破壞腦組織血腫擠壓周圍組織，引起腦組織水腫、顱內(nèi)壓增高，嚴(yán)重可引起腦疝臨床表現(xiàn)

subarachnoidhemorrhage,SAH蛛網(wǎng)膜下腔出血是多種病因所致腦底部或腦及脊髓表面血管破裂的急性出血性腦血管病，血液直接流入蛛網(wǎng)膜下腔，又稱原發(fā)性SAH。此外，臨床還可見因腦實(shí)質(zhì)內(nèi)、腦室出血、硬膜外或硬膜下血管破裂等血液穿破腦組織流入蛛網(wǎng)膜下腔者，稱為繼發(fā)性SAHSubarachnoidhemorrhage,SAH—theprimarysubarachnoidhemorrhage.Manyetiologicalfactorsmakecerebralbasalpart,cerebralandspinalcordsurfacebloodvesselsrupture.Followingthese,bloodenterssubarachnoidspace,whichiscalledSAH.Inaddition,succeedingSAHisthatbloodenterssubarachnoidspacewhichiscausedbyrupturingofbloodvesselincerebralparenchyma,epidural,infraduramaterorventricularhemorrhage.病因
