Wake wacabanga ukuthi ubuchopho bethu buyinkimbinkimbi futhi buklanywe ngendlela emangalisayo kangakanani? Ukuze ubuchopho busebenze kahle, budinga ukuhlinzekwa njalo kwegazi elihlanzekile neligcwele umoya-mpilo. Ngakho-ke ukuze benze lo msebenzi kahle, ubuchopho bunohlelo lokuphepha olumangalisayo kakhulu. Kufana nendawo enkulu ephakathi kwedolobha, ekusiza ukuthi uthathe omunye umgwaqo uma kukhona ukuminyana kwezimoto. Namuhla sikhuluma ngalolu hlelo lokuphepha olumangalisayo.
Iyini i-Circle of Willis?
Kalula nje,
i-Circle of Willis (CoW) iyisakhiwo esifana nendandatho esakhiwe yimithambo yegazi
(imithambo yegazi) etholakala phansi kobuchopho bethu, okungukuthi, phansi. Inesimo esifana ne-pentagram. Lena yindawo exhumanisa imithambo yegazi emibili eyinhloko enikeza igazi ebuchosheni bethu. Cabanga ukuthi kunemithambo yegazi emibili eyinhloko eletha igazi ebuchosheni bethu. 1.
I-Internal Carotid Artery: Lena yindlela enikeza igazi eliningi ngaphambili kobuchopho. 2.
I-Vertebral Artery: Lena yindlela enikeza igazi ngemuva kobuchopho. Ngakho-ke, yomibili le mithambo emikhulu ihlangana endaweni ezungezayo ebizwa ngokuthi i-Circle of Willis. Ngenxa yalokhu, uma kukhona ukuvinjelwa noma ukuvaleka komthambo owodwa, igazi lingathunyelwa endaweni edingekayo ngomunye umthambo. Lokhu kufana nohlelo lwemvelo 'oluphephile' lokuphepha kobuchopho bethu. Ibizwa ngokuthi "i-Ring of Willis" ukuhlonipha isazi se-anatomist uThomas Willis, owathola okuningi ngalesi sakhiwo esimangalisayo.
Ingabe wonke umuntu unalo leli ndandatho?
Nansi into emangalisayo. Ngokusho kwabacwaningi, abantu abangaphansi kwengxenye yabantu banendandatho
ephelele ye-Willis . Lokho kusho ukuthi iningi labantu lingase libe nokwehluka okuncane, noma ukungapheleli, kule ndandatho. Ukuhlukahluka okunjalo kungokwemvelo. Lezi izinguquko zemvelo ezenzeka lapho imithambo yethu yegazi yakheka esibelethweni. Lokhu akusona isifo noma isici.
Ukuba nendandatho kaWillis engaphelele akusho ukuthi uyagula. Abantu abaningi baphila impilo enempilo ngendandatho kaWillis engaphelele.
Kodwa, nansi into. Uma umuntu one-annulus engaphelele enesifo esihlobene nemithambo yegazi ebuchosheni, njenge
- stroke , imiphumela ingaba mikhulu kancane. Ngoba leyo 'ndlela ehlukile' noma 'indlela yokuphambuka' esikhulume ngayo ayisebenzi kahle. Lokhu akuyona into esingayishintsha, yile ndlela umzimba wethu owakhiwe ngayo.
Iyini incazelo yangempela yeRing of Willis?
Indlela engcono kakhulu yokuqonda lokhu ukucacisa ngesibonelo se-traffic roundabout esikhulume ngaso ekuqaleni. Cabanga nge-roundabout enkulu efana naleyo ese-Colombo Town Hall. Ixhumanisa imigwaqo emikhulu eminingana. Manje cabanga ukuthi kunengozi enkulu komunye wemigwaqo emikhulu futhi umgwaqo uvalwe ngokuphelele. Kwenzekani-ke? Izimoto ezivela kweminye imigwaqo zingasebenzisa le roundabout, zidlule umgwaqo ovalwe bese zifika lapho ziya khona. I-Ring of Willis yenza
lokhu kanye . Uma umthambo wegazi omkhulu othwala igazi ebuchosheni uvalekile noma wonakele, uma kukhona i-Ring of Willis ephelele, igazi elivela kolunye uhlangothi lingadlula kule ring futhi linikeze igazi engxenyeni yobuchopho ephucwe igazi. Lokhu kuvimbela umonakalo omkhulu ezimweni eziningi. Ukuba ne-Ring of Willis ephelele kungakuvikela emiphumeleni emibi yalezi zimo ezilandelayo:
| Isimo sezokwelapha | Isivikelo esinikezwa yiRing of Willis |
|---|
| Isifo sohlangothi | Ngisho noma umthambo wegazi uvalekile, igazi liyaphambukiswa ngenye indlela, okunciphisa umonakalo ebuchosheni. |
| Ukuqhuma kwe -aneurysm yobuchopho | Kusiza ukugcina igazi litholakala ezindaweni ezizungeze umthambo owonakele. |
| Ukuqongelela kwamafutha emithanjeni yegazi (i-atherosclerosis) | Njengoba umthambo uncipha kancane kancane, ukugeleza kwegazi kweminye imithambo kuyanda ukuze kulungiswe ukuntuleka kwawo. |
| Isifo Semithambo Ye-Carotid | Ngisho noma umthambo omkhulu entanyeni uvaleka, uyasiza ekugcineni igazi ligeleza ebuchosheni. |
Yimaphi amathuba okuthi udokotela akutshele ngalokhu?
Ngokuvamile, abantu abaningi ngeke bazi ukuthi banendandatho kaWillis baze baxilongwe. Kodwa-ke, kwezinye izimo, udokotela wakho angakutshela ngakho.
- Uma une -aneurysm yobuchopho: Cishe u-85% we-aneurysms yobuchopho yenzeka ku-Ring of Willis.
- Uma une- stroke : I-stroke ingabangelwa ukuvaleka noma ukuphuma kwegazi emthanjeni wegazi eRingini likaWillis.
- Uma unesifo seMoyamoya: Lesi yisifo esingavamile kakhulu esibangela ukuthi imithambo yegazi eseRingini likaWillis inciphe kancane kancane futhi ivaleke.
- Uma kudingeka ukuhlinzwa phansi kobuchopho: Isibonelo, lapho kwenziwa ukuhlinzwa kwe-aneurysm noma isimila se-pituitary gland, kubaluleke kakhulu ukugwema ukulimaza indandatho kaWillis.
- Uma une -brain scan : Uma une-exam ekhethekile, njenge -MRI yobuchopho noma i-cerebral angiogram, umbiko ungafaka ulwazi mayelana nohlobo lwe-Ring of Willis yakho.
Yini okufanele siyenze ukuze sigcine iRing of Willis iphilile?
Njengoba sixoxile ngaphambili, asikwazi ukushintsha isakhiwo seRing of Willis. Kuyinto ekhona lapho umuntu ezalwa. Kodwa-ke, kunezinto eziningi esingazenza ukuze sigcine imithambo yegazi engaphakathi kwaleyo ring iphilile futhi ingenazo izithiyo. Kalula nje,
sidinga ukulawula izici eziyingozi ezonakalisa imithambo yegazi ebuchosheni. Ake sibheke ukuthi ziyini lezi zinto eziyingozi. Ukulawula lezi akukuhle kuphela kwiRing of Willis yakho, kodwa nakuwo wonke umzimba wakho, ikakhulukazi inhliziyo yakho.
| Isici sengozi | Okufanele ngikwenze |
|---|
| Umfutho Wegazi Ophakeme | Sebenzisa umuthi njengoba nje udokotela emyalile. Nciphisa usawoti odliwayo. Zivocavoce. |
| I-Cholesterol Ephezulu | Nciphisa amafutha, ukudla okuthosiwe, kanye nokudla okusheshayo. Yidla imifino eminingi, izithelo, kanye nemifino eluhlaza. |
| Isifo sikashukela | Gcina amazinga kashukela egazini lakho elawulwa. Landela ukudla kwakho kanye neseluleko sezokwelapha. |
| Ukubhema | Yeka ukubhema ngokuphelele. Lokhu kubangela umonakalo omkhulu emithanjeni yegazi. |
| Ukukhuluphala ngokweqile | Lawula isisindo somzimba wakho ngokudla okufanele kanye nokuzivocavoca njalo. |
| Ukusetshenziswa Kotshwala | Gwema ukuphuza utshwala ngokweqile. |
Into engcono kakhulu ongayenza ukukhuluma nodokotela womndeni wakho ngalezi zinkinga bese ulungisa indlela yakho yokuphila ukuze ivumelane nawe.
Umlayezo Wokuya Nawe Ekhaya
- I-Circle of Willis iyindandatho evikelayo phansi kobuchopho eyakhiwa yiqoqo lemithambo yegazi ehambisa igazi ebuchosheni.
- Umsebenzi wayo oyinhloko ukunciphisa umonakalo ebuchosheni ngokuphambukisa igazi ngenye indlela uma omunye wemithambo yegazi ethwala igazi ebuchosheni uvalekile.
- Akuwona wonke umuntu onale ndandatho 'ephelele'. Iningi labantu linokwehluka okuncane. Akusona isifo, kodwa yisimo semvelo esivela ekuzalweni.
- Nakuba singenakukwazi ukushintsha isimo sale ndandatho, singayigcina le mithambo yegazi iphilile ngokulawula umfutho wegazi, i-cholesterol, isifo sikashukela , nokugwema ukubhema.
- Uma uhlolwa ubuchopho noma ukhuluma ngesimo sempilo, uma udokotela ekhuluma ngalokhu, ungesabi ukubuza nokuthola. Unelungelo lokwazi ngomzimba wakho.
Umjikelezo kaWillis, ukuhlinzekwa kwegazi ebuchosheni, isifo sohlangothi, i-aneurysm yobuchopho, imithambo yegazi ebuchosheni, isakhiwo sobuchopho, i-anatomy ngesiSinhala
