Zesikhashana kuhlasela ischemic

Zesikhashana kuhlasela ischemic, ngokuvamile ukuthuthukisa ngokuzumayo isho noma yiluphi ukuntuleka ebalulekile ephindela ngokuphelele ngaphansi kwamahora amabili nane. Lenchazelo kuyahluka ububanzi izimpawu ezinhlobonhlobo. Kufanele kuqashelwe ukuthi isimo abanakwethenjwa ngaso sonke isikhathi senziwa ischemia. Ngokwesibonelo, migraine noma nabanesithuthwane syndrome ephelezelwa ebalulekile ukubonakaliswa zezinzwa. Ukulondoloza izimpawu ischaemia isikhathi esingaphezu kwehora kungase kubonise ukuthi angomunye ubuchopho izicubu infarction zabhekana.

Specific ukubonakaliswa isimo ubonisa ukuthi le nqubo esigabeni sokugembula ehlinzekwa wumnikezeli ngegazi nge Umthambo ethize (maphakathi palsy, carotid, kanye nezinye).

Zesikhashana kuhlasela ischemic has izindlela pathophysiological. On leli qiniso likhombisa stereotypical nemvelo, ubude kanye nokuvama iziqephu yansukuzonke.

Ngokwesibonelo, okufutshane-time (imizuzu eyishumi nanhlanu noma ngaphansi), okuphindaphindiwe (izikhathi emihlanu kuya kweyishumi ngelanga), uhlobo olulodwa lobuthakathaka nokuquleka wonke esandleni noma esihlakaleni nokuba khona (noma ukungabi khona) yokukhuluma iziyaluyalu kungase kubonise ukuvaleka proximal noma occlusion kwemithambo yegazi, ephelezelwa ukuntula in eseduze liningi igazi. Lesi simo kuholela ischemia ebalulekile cortex ukunakwa abobulili Nenkabazwe. Nokho, ngakolunye uhlangothi, omunye isiqephu yokukhuluma isiyaluyalu nayo ubuthaka isandla noma esihlakaleni ngesikhathi amahora ayishumi nambili siyenzeka at ongaphakeme ukugeleza kwegazi ngenxa embolism. Ndawonye nale cishe obumba endaweni infarct e kwesokunxele Lobe engaphelele.

Acute unhlangothi ischemic echibini omunye imithambo eyenza umuntu acabange eseZwini kubangela ukuthuthukiswa kwe-lesion, esingeqile eyodwa isentimitha. Lesi simo luchazwa ngokuthi transiently-lacunar kuhlasela ischemic. Standing ohlelweni basilar-vertebral, esimweni uma base bekhulelwe umphumela distal (zamazwe amabili) noma proximal basilar Umthambo stenosis e ezilwaneni ezinomgogodla, ngokuvamile kubonakala khona iziphonso isiyezi, dysarthria futhi umbono double.

Ngakho, lezivakashi kuhlasela ischemic cuphuluza izici ezimbili: embolism futhi amathonsi ebalulekile liningi igazi. Esimweni sokuqala, isimo indlela isobala. Ngezinga elincane nesenzakalo wafunda TIA isizinda ukunciphisa endawo igazi ebuchosheni. Kungenzeka ukunciphisa inflow ngenxa lwemithambo stenosis noma occlusion of ngezinga ezibucayi. Lokubaluleke kakhulu iyona basuke bengenazo izibambiso igazi ligeleze endaweni ischemia. Ngaphezu kwalokho, kubalulekile ukuba acabangele kuyaqina bomkhumbi odongeni, igazi viscosity nezinye izinto. Zesikhashana kuhlasela ischemic amafomu ezifana uthathwa njengomgcini kweqiniso, okungukuthi, njengoba iziqephu akuzona umsuka embolic.

State abaphindela ngokuphelele. Nokho, ukubukeka kwabo nesixwayiso amathuba unhlangothi esikhathini esizayo. Ngakho, izindlela pathophysiological kulaba ababili uthi kufanele kubhekwe ndawonye. Kufanele kuqashelwe ukuthi udokotela akakwazi ukuba anakekele iziguli ukuhlaselwa lezivakashi ischemic, engazi nezimbangela zayo. Lapho lesi simo kuyadingeka ukubeka ukuxilongwa ethize.

esibhedlela okuyimpoqo iziguli wadalula iminyaka nokuba izikhalazo ngaphezu kwangaphambili iminyaka emihlanu (ngaphandle kucatshangelwa nobudala) amadala kwamashumi amane nanhlanu. Ukwelashwa kuboniswa ngenxa izifo zenhliziyo, kuhlanganise isifo sokuqina kwemithambo yegazi, ngemva akukho izinsuku ezingaphezu kwezimbili kusukela ngomzuzu ukuthi kukhona lezivakashi kuhlasela ischemic. Ukwelashwa Kwenziwa esibhedlela ngemuva kocwaningo kunesidingo ukuze kuqinisekiswe lesi sifo. Ukwelashwa ihlose ekuvimbeleni isimo Ukuphinda, kanye nesenzakalo yokushaywa unhlangothi, isifo senhliziyo.
