Iimpendulo zokuthi 'Ziyintoni i-Stroke?' 'Yintoni Edala Ukubetha?' kunye nokuninzi
Ulivile ixesha eliphindaphindiweyo kodwa uyaqhubeka uzibuza: Yintoni na ukubetha? I-stroke yintlupheko engxamisekileyo kwimisebenzi yengqondo. Omnye unokufumana ubunzima bokuthetha okanye ukuthetha ngokucacileyo, ukuhamba, okanye ukuhambisa isigxina ngenxa yokuba igazi liyekile ukuhamba kummandla wengqondo. Ngokuqhelekileyo, oku kubangelwa ukucinywa, okanye ukuphuka, kwesitya segazi.
Ngokungafani neentlangano, ezibizwa ngokuba yi- TIA) , izibonakaliso zabo zizenze zenzeke kwiiyure ezingaphantsi kweeyure ezingama-24, imivimbo ihamba emva kokuphazamiseka kweengxaki ezingapheliyo.
Ubunzima bezinto eziyimpembelelo kuxhomekeke ekubeni umonakalo omkhulu kangakanani kwingqondo, kwaye inxalenye yengqondo echaphazelekayo.
Ziziphi iintlobo ezahlukeneyo zesisu?
Kukho iindidi ezibini zokubetha: ischemic and hemorrhagic.
Olu hlobo lwesisu luyabangelwa ukukhutshwa komzimba wegazi ukuhamba kwindawo yengqondo. Iintlobo eziqhelekileyo zesifo sokukhwabanisa zi:
1) I-Embolic Stroke
Olu hlobo lwesifo luya kwenzeka xa i-clot yegazi okanye i-cholesterol plaque idlulela engqondweni ize ifike kwindawo encinci apho ibanjwa khona. Oku kubangela ukucinywa kwe-artery kwaye kuthintela igazi ekufikeleleni kwicandelo lobuchopho. Kukho ezinye, izizathu ezingaphantsi kwezihlandlo zeempawu ezibandakanya:
2) I-Stroke ye-Thrombotic
Kulo hlobo lokubetha iifom zegazi kunye neengxube zegazi ezibangela ukuphazanyiswa kwegazi kwiindawo zobuchopho.
I-blood clot enjalo, eyaziwa nangokuthi i-thrombus, isoloko ichaphazela imithana encinane yegazi kwingqondo, ingakumbi kubantu abane-cholesterol ephezulu.
EziPhakamileyo zeCholesterol
Ngenxa yokuba iinqanawa zegazi ezincinci zithatha igazi kwiindawo ezincinci zeengqondo, izibetho ze-thrombotic zincinci, kwaye ngamanye amaxesha zibizwa ngokuba yi- lacunar .
Kwezinye iimeko ezinqabileyo, nangona kunjalo, i- clot enkulu yegazi ingayifaka ngaphakathi kwimizi emikhulu yegazi entanyeni, kwaye emva koko iphele ikhiphe i-stroke enkulu .
Utyando lweHemorrhagic
Olu hlobo lwesifo luya kwenzeka xa isitya segazi ngaphakathi kwengqondo siphuka, ukuvumela igazi ukuba lidibanise ngaphakathi okanye malunga nezicubu zeengqondo eziphilileyo. Kwiimeko ezininzi, oku kungumphumo wokunyanzeliswa kwegazi ophezulu ongalawulwayo.
Ezingundoqo zeengcinezelo zegazi
Ngokuxhomekeka kwindawo ekuphumayo ngayo, isifo esiqhekezayo sisabelana
- Intracerebral Hemorrhage : Ukuhlamba kwenzeka ngaphakathi kweengxube zeengqondo.
- Umonakalo we-Subarachnoid : Ukuhlamba kwenzeka kwi-space phakathi kwembini zeembrane ezifihla ingqondo.
- I-Hemorrhage ye-Intraventricular: Ukuhlamba kwenzeka ngaphakathi kweengxenyana zengqondo, ezingenayo i-brain tissue, kodwa kunoko zizaliswe ngumsebenzisi owaziwa njenge-cerebro-spinal fluid. Igazi ngaphakathi kweefriji ezinqabileyo zingabangela ukuba zibethe ngokwazo, kodwa zinokubangela ukuba i- hydrocephalus imeko ephakamileyo yongcinezelo yongxowankulu ingabangela isifo kunye nokufa.
- Ukuhlaselwa kwesigxina : Ukuhlamba kwenzeka ngaphandle kweengxube zengqondo kufuphi nekhanga.
Izibetho ezinomdla zivame ukubangelwa yinqwelo egazini yegazi efana ne- aneurysm okanye i-malm ephazamisayo (i-AVM).
Igazi ngaphakathi kwengqondo livelisa intloko enzima kakhulu, echazwe ngabantu ngabantu njengeyona nto ibuhlungu kakhulu ebomini babo.
Njengoko igazi libuthelela kwingqondo, izicubu zengqondo ziqhelekile kwiindonga zekhanga. Le nkqubo ikhulisa uxinzelelo ngaphakathi kwengqondo, kwinqanaba lokuba ukuphuma kwegazi kwiindawo eziphezulu zengcinezelo ziphazamisekile. Ezi ndawo ziyeke ukusebenza kwaye zibangele iimpawu ezinokuthi zihluke kwizondlo, isicupunu kunye nokuhlanza kwintloko ehamba kunye neempawu eziphazamisayo . Iimpawu eziphazamisayo zegazi zifanele zinyanzeliswe njengoko zihlala zikwazi ukuguquka ngokukhawuleza nakwiimeko ezimbi, zingakhokelela ekufeni ngokukhawuleza.
