Ziziphi iipon?
Iiponi ngummandla wengqondo efumaneka kwi-brainstem. Iiponi zincinci, kwaye zifumaneka kwingxenyana engaphantsi kwengqondo, ukudibanisa i-cortex ye-cerebral kunye ne-medulla oblongata. Iipon iqulethe iisondlo kunye namaphetshana emigulane (iindlela) ezidibanisa imisebenzi yengqondo ezifana nokunyakaza kunye nemiyalezo yenzwa phakathi kwengqondo kunye nomzimba.
Iiponi zidibanisa ukulinganisela entloko, entanyeni nasemzimbeni kwaye idlala indima ephambili ekuhambeni kwamehlo, ukulala, ukuphupha, ukugaya, ukugwinya, ukuphefumla, kunye nentliziyo.
Ngokwezenzululwazi, ii-pons ngezinye izihlandlo zibizwa ngokuba yi-hindbrain, igama elisekelwe kwindawo yeepons ngokubhekiselele kuyo yonke ingqondo ngexesha lophuhliso lwengqondo embryo (ukuvelisa umntwana.)
Izizathu
Ukubetha okubandakanya iipon kungabangelwa yi-clot yegazi (isicic stroke) okanye i-bleed (isifo esiyingozi).
I-stroke ye-ischemic iyenzeka xa i-clot yegazi ifom, ivimba ukuhamba kwegazi ngokusebenzisa umthambo kwindawo ethile kwingqondo. Izaziso ezinzima zenzeka xa isitya segazi siphuka, sinciphisa okanye sinciphisa ukuhamba kwegazi kummandla wengqondo.
Ingaba i-stroke i-ischemic okanye i-hemorrhagic, xa igalelo legazi kummandla wengqondo liphazamisekile, iseli zengqondo ziqala ukufa, ezibangele umonakalo wengqondo .
Ukuphuma kwegazi kudala kungonakalisa umonakalo ngenxa yokuxinzelelo kunye nokucasula kwizakhiwo zengqondo ezisondeleyo.
Iimpawu zenyama kunye nengqondo (ukukhumbula, ukucinga) ubuchule obulawulwa yintsipho yengqondo apho kuphazamiseka khona isifo. Ubungakanani bomonakalo buxhomekeke kwindawo kunye nobukhulu be-stroke.
Kwiimeko ezinqabileyo, ukubetha okubandakanya iipon, okubizwa ngokuba yi-pontine, kungabangela ukulimala komtsalane obangelwa intloko okanye intlungu. Oku kunokwenzeka ngenxa yokuba imithwalo yegazi inika igazi kwiipon kunye nayo yonke inkunkuma ye-brainstem ikhona emqaleni kwentamo, kwaye inokulimala ngenxa yexinzelelo yentamo okanye ukunyanzeliswa ngokukhawuleza okanye ukunyuka kwentloko okanye intamo.
Iimpawu
Izibetho ezenzeka kwiipon zingabangela iintlobo ezininzi zeempawu ezinzulu, nangona indawo encinane yomonakalo ebandakanyekayo.
Ezinye zeempawu ze-pontine uhlangothi luquka ukudibanisa kwezi zilandelayo:
- Ubunzima bokulinganisela
- I-Vertigo (ukutyikitya inzwa)
- Utywala
- Umbono ombini
- Ukulahlekelwa kolawulo
- Ukuthoba ubunzima
- Amagama awanzima
- Ubungqina
- Ukulahlekelwa kwintlungu
- Ubuthathaka kwisiqingatha esinye somzimba
- I sizathu
- I-pontine stroke inokubangela imeko enzima ebizwa ngokuba yi -syndrome . Abantu abavalelwa kwi-syndrome bangakwazi ukuphaphama, baqaphele kwaye bakwazi ukucinga nokuqonda, kodwa banokukwazi ukuhambisa amehlo abo.
Ukuxilongwa
Ukuxilongwa kwe-stroke i-pontine kudinga ukuhlolwa kwe-neurologic . Ezinye iimvavanyo zokucinga ze-diagnostic ezifana ne-Brain MRI kunye ne-Brain MRA okanye i-CT angiogram zingancedisa ukuxilongwa kwe-pontine.
Izinto zobungozi
Iziganeko zobungozi be-pontine isifo esifana nezo zibetha kwezinye iindawo zengqondo, kuquka:
- Igazi elonyukayo
- Sikashukela
- Isifo sentliziyo
- I-fibrillation ye-Atrial
- Ukutshaya
- Yobudala
- Imbali yengonyango yentsapho yecroke
- Ukunyanya
- I-cholesterol engcolileyo kunye namanqatha
- Ukungasebenzi
- Ukusetyenziswa kweziyobisi
Unyango
Unyango lwe-stroke luxhomekeke ekuthotyeni unyango ngokukhawuleza.
Unyango nge-clot ye-drug-dissolving, i-activminogen activator (tPA) inokusebenza ngonyango lwe-stroke ye-ischemic kuphela xa ilawulwa zingakapheli iiyure ezintathu zokuqala kweempawu zokubetha.
Ngexesha lokuphulukana emva kokuphazamiseka, kukho iindlela ezininzi zokwelapha ezinokubangela ukuphucula ukuphuculwa , kubandakanywa abancinci begazi, ukuphathwa kwamanzi, unyango lweengxaki zentliziyo nokugcina ukutya okwaneleyo.
ILizwi
Ukubuyiselwa kwi-pontine isifo sinokwenzeka.
Ukuba uye wafumana unxephezelo lwe-pontine, xa iimpawu zakho zizinzileyo ngokuhamba kwexesha, ukugxilwa kwento yakho yokubuyisela kuya kusekelwe ekukhuseleni iingxaki ezinjengokukhahlela kunye nokuthintela ukubetha okuthe xa kwenzeka.
Izibetho kwi-brain stem ayichaphazeli ubuchule beelwimi, kwaye oku kwenza kube lula ukuthatha inxaxheba kwipilisi yokuvuselela. I-Vertigo kunye nemibono emibini ixazulula ukuba i-stroke iyancipha okanye imodareyitha. Ukwelapha ngokwenyama kunye nokuvuselelwa kubalulekile kubandakanyeka ukuhlaselwa kwesifo.
