Ngaba wakha wazibuza ukuba eli lungu limangalisayo libizwa ngokuba yingqondo yethu lisebenza njani imini nobusuku? Isizathu esiphambili saloo nto kukufumana igazi rhoqo. Sonke sivile ngemithambo yegazi emikhulu engaphambili entanyeni (imithambo ye-carotid), kodwa ubusazi na ukuba kukho enye imithambo yegazi ebaluleke ngokulinganayo ethwala igazi liye engqondweni ukusuka ngasemva entanyeni, ngaphakathi emqolo? Yiloo nto siza kuthetha ngayo namhlanje.
Ngamafutshane, yintoni iVertebral Artery?
Imithambo yegazi ye-vertebral yimithambo yegazi emibini emikhulu ehamba ngemithambo yegazi entanyeni yethu kwaye ihambisa igazi kwingqondo nakwintambo yomqolo. Ngokuchanekileyo, sinemithambo yegazi ye-vertebral emibini , enye ngasekunene nenye ngasekhohlo. Le mithambo mibini ihamba inyuka ngomqolo ize idibane ezantsi kwekhakayi ukuze yenze umthambo wegazi omkhulu. Siwubiza ngokuba yi-basilar artery. Ngokwezonyango, le nkqubo iphela ibizwa ngokuba yi-vertebrobasilar system .
Khawuthelekelele, ingqondo yethu ifana nesixeko esikhulu. Kukho imibhobho emibini ephambili ehambisa amanzi kweso sixeko. Omnye yimithambo ye-carotid esiyaziyo sonke. Omnye umbhobho obaluleke kakhulu ngulo mthambo we-vertebral.
Ibaluleke ngantoni le mithambo yegazi?
Indima yale mithambo yegazi ayibalulekanga kangako. Le mithambo mibini yethambo lomqolo inika i-20% yegazi lilonke ebuchotsheni, eliliziko lolawulo lomzimba wethu wonke. I-80% eseleyo ivela kwimithambo ye-carotid esiyikhankanyileyo ngaphambili.
Le mithambo yegazi ikwahluma ibe ngamasebe amancinci. Elona candelo likhulu kula linika igazi kwinxalenye ebaluleke kakhulu yobuchopho bethu. Yiyo leyo i-cerebellum, okanye i-cerebellum.
Kwenzeka ntoni kwi-cerebellum?
Uyakhumbula indlela owafunda ngayo ukukhwela ibhayisekile usengumntwana? Wawa kangaphi wawa ekuqaleni? Kodwa emva koko waqhela. Ngendlela efanayo, izinto ezininzi emzimbeni wethu, ezinje ngokulinganisela , intshukumo , intetho, kunye nokubona, zilawulwa kakuhle yile nxalenye yengqondo. Ngoko cinga ngendlela exabiseke ngayo le mithambo yomqolo enika igazi kuyo.
Iphi le mithambo yomqolo?
Le mithambo yegazi mibini iqala kwinxalenye ephezulu yesifuba sethu, ngaphantsi nje kwe-collarbone, njengemithambo yegazi ebizwa ngokuba yi-subclavian arteries. Ukusuka apho, ihamba iye phezulu ngemingxuma ekhethekileyo (i-transverse foramen) kwi-vertebrae yentamo, njengemoto edlula kwiingxunya ezininzi kwindlela yeentaba.
Kolu hambo, le mithambo yegazi yahlulwe yangamacandelo amane kwaye ibizwa ngokuba yiyo. Nangona oku kuyinto yezonyango kancinci, masiyijonge ngale ndlela ukuze kube lula ukuyiqonda.
| Icandelo | Kalula nje... |
|---|---|
| Inxalenye V1 | Ukuqala kohambo: Le yindawo apho umthambo wegazi uqala khona de ungene emgogodleni. |
| Inxalenye V2 | Uhambo ngaphakathi komqolo: Le nxalenye yomqolo wesibeleko ihamba ukusuka kwi-C6 ukuya kwi-C2 inyuka yonke ngaphakathi kwithambo lomqolo. Kufana nokuhamba ngaphakathi kwikheyiji ekhuselekileyo. |
| Inxalenye V3 | Goba phambi kokuba ungene ekhayeni: Lo mthambo wegazi ujikeleza ngaphezu kwethambo eliphezulu lentamo (C1), ulungiselela ukungena ekhayeni. |
| Icandelo V4 | Indawo oya kuyo - Intracranial: Indawo apho umthambo wegazi ungena khona ekhayeni uze udibane nomthambo wethambo lomqolo kwelinye icala ukuze kwenziwe umthambo wethambo we-basilar. |
Ziziphi izifo ezichaphazela le mibhobho yegazi ixabisekileyo?
Njengeminye imithambo yegazi, le mithambo yegazi yomqolo nayo inokuba neengxaki. Ingxaki ephambili kukuqokelelana kwamafutha kunye ne-cholesterol ngaphakathi kwemithambo yegazi. Oku sikubiza ngokuba yi -atherosclerosis .
Khawucinge nje ngokufana nokugqwala okwakhela ngaphakathi kombhobho wamanzi ngokuhamba kwexesha. Emva koko ingaphakathi lombhobho liyancipha kwaye ukuhamba kwamanzi kuncipha. Yiyo loo ndlela ioyile eqokelelana ngayo ngaphakathi kwezi mithambo yegazi. Siyibiza ngokuba yiVertebral Artery Stenosis , oko kuthetha ukuba umthambo wegazi uyancipha.
Xa imithambo yegazi incipha ngolu hlobo, iziphumo ezininzi eziyingozi zinokwenzeka:
- Amahlwili egazi:Ukuhamba kwegazi kunokuvaleka kwiindawo ezixineneyo kwaye kungenzeki amahlwili egazi. Ukuba eli hlwili legazi liyaqhekeka lize livale omnye umthambo omncinci engqondweni, kunokuba yingozi kakhulu.
- I-TIA (i-Ministroke) kunye ne-Stroke: Ukuqhekeka kwegazi okanye ukuvaleka kwegazi eliya kwinxalenye yengqondo kunokuyonakalisa. Oku sikubiza ngokuba yi-stroke. Ngamanye amaxesha iimpawu ziyavela zize ziphele imizuzu embalwa. Oku kubizwa ngokuba yi-"Transient Ischemic Attack - TIA" okanye i-ministroke. Oku kukwaluphawu olubalulekileyo lwe-stroke enkulu.
- Ukungasebenzi kakuhle kwemithambo-luvo: Oku kuthetha ukuba umva wengqondo awufumani gazi laneleyo. Oku kunokubangela iimpawu ezifana nesiyezi, ukukhubeka xa uhamba, kunye nokungaboni kakuhle.
Ukongeza, kukho nezinye iingxaki ezininzi:
- Ukuqhaqha kwemithambo yegazi: Le yimeko apho udonga lomthambo wegazi lunokukrazuka ngenxa yengozi, ukwenzakala entanyeni, okanye iimeko ezithile zemfuza (umz. i-fibromuscular dysplasia). Le yimeko engxamisekileyo enokubangela isifo sohlangothi.
- Isifo sikaBowhunter: Esi sisifo esingaqhelekanga. Okwenzekayo kukuba xa umntu ejika intloko yakhe ecaleni, ukukhula kwamathambo, okubizwa ngokuba yi-bulging disc, kuyayicinezela i-vertebral artery. Igama layo livela kuba lifana nesimo somntu odubula isaphetha. Iimpawu ezifana nesiyezi kunye namehlo aluhlaza okwesibhakabhaka zenzeka kuphela xa intloko ijikisiwe.
Sizikhusela njani ezi mithambo yegazi zixabisekileyo?
Ekubeni eyona nto iphambili yomonakalo kule mithambo yegazi kukuncitshiswa kwemithambo yegazi (i-stenosis) esithethe ngayo ngaphambili, eyona nto ingcono onokuyenza kukuthintela oko. Kukho izinto ezilula, kodwa ezibaluleke kakhulu onokuthi uzenze ukuze wenze oko.
- Yiba ngumntu okhutheleyo: Fumana ubuncinci imizuzu engama-30 yokuzilolonga ngamandla aphakathi phantse yonke imihla evekini. Ukuhamba ngokukhawuleza, ukubaleka, okanye ukukhwela ibhayisekile zezona ndlela zilungileyo.
- Yitya ukutya okunempilo kwentliziyo: Nciphisa ukutya okuneoyile eninzi, i-cholesterol, kunye netyuwa kangangoko unako. Faka iziqhamo, imifuno, iimbotyi kunye neentlanzi ezincinci ekutyeni kwakho.
- Gcina ubunzima obusempilweni: Kubaluleke kakhulu ukugcina ubunzima obufanele ubude bakho. Ukuba utyebile kakhulu, zama ukunciphisa ubunzima kancinci kancinci.
- Lawula ezinye izifo: Ukuba unezifo ezifana nesifo seswekile, uxinzelelo lwegazi oluphezulu, okanye i-cholesterol ephezulu , landela imiyalelo kagqirha wakho kwaye usebenzise amayeza amiselweyo ngqo ukuze uzilawule.
- Kuphephe ukutshaya ngokupheleleyo: Ukutshaya yeyona nto ibangela ukonakala kwemithambo yegazi. Ukuba uyatshaya, yenza konke okusemandleni akho ukuyeka. Yeyona nto ilungileyo onokuyenza emzimbeni wakho.
Ufanele uye nini kugqirha?
Kukho iimpawu ezithile, ukuba ziyavelaAkucetyiswa ukuba ulibazise konke konke. Ezi zinokuba ziimpawu zestroke. Eyona nto ingcono onokuyenza ngexesha elinjalo kukuya kwiSebe leNgxamiseko (ETU) kwisibhedlele esikufutshane ngoko nangoko.
| Qaphela! Ukuba unale mpawu, yiya kwi-ETU ngoko nangoko! | |
|---|---|
| I-Vertigo Enzima | Isiyezi esingalawulekiyo esivakala ngathi ihlabathi liyakujikeleza. |
| Ukungalingani | Ukuziva ngathi uza kuwa, awukwazi ukuma okanye ukuhamba ngokuthe tye. |
| Utshintsho lombono | Ukubona kabini okanye ukulahleka ngequbuliso kokubona. |
| Ukukhubazeka komzimba | Ukuba ndindisholo okanye ubuthathaka kwelinye icala lobuso, ingalo, okanye umlenze. |
| Ukurhuqa nokuwisa ngaphandle kwesizathu | Ukuba ngequbuliso uwela phantsi ngaphandle kwesizathu esithile, ngaphandle kokulahlekelwa zingqondo. |
Musa ukuzityeshela ezi mpawu. Ixesha libaluleke kakhulu xa uhlaselwa sistroke. Umzuzwana ngamnye odlulayo ngaphandle konyango unyusa umonakalo engqondweni. Ke ngoko, kubalulekile ukufuna ingcebiso kagqirha ngoko nangoko.
Umyalezo Wokuya Ekhaya
- Imithambo yegazi emqolo yimithambo yegazi emibini ebaluleke kakhulu enika igazi engqondweni yethu nakwithambo lomqolo.
- Ukuqokelelana kwe-cholesterol ngaphakathi kwezi mithambo yegazi kunokubangela ukuxinana (i-stenosis) kunye neemeko ezinzulu ezifana ne-stroke.
- Indlela yokuphila esempilweni (ukutya okunempilo, ukuzilolonga, kunye nokuphepha ukutshaya) inokukhusela le mithambo yegazi ixabisekileyo.
- Ukuba ufumana iimpawu zestroke, ezinje ngesiyezi esinzima, ukulahleka kolungelelwano, utshintsho embonweni, okanye ukuphelelwa zimvakalelo kwelinye icala lomzimba, musa ukuchitha ixesha kwaye yiya kwiSebe lezeMpilo eziNgxamisekileyo (ETU) lesibhedlele ngoko nangoko.
- Ukuba unenkxalabo malunga nempilo yakho, thetha nogqirha wakho wosapho.
