Ubuwazi ngemithambo yegazi emangalisayo "esekelayo" emizimbeni yethu? (Ukujikeleza kwegazi okuhlanganisiwe) Ake sixoxe!

Namuhla sizokhuluma ngento emangalisayo nebalulekile emzimbeni wethu . Cabanga nje, uma umgwaqo omkhulu owuthathayo uvaleka ngokuzumayo, yeka ukuthi kubaluleke kangakanani ukuba neminye imigwaqo emincane eseceleni ohamba kuyo. Ngokufanayo, emzimbeni wethu, uma umthambo wegazi oyinhloko (umthambo wegazi) uvaliwe noma wonakele, kukhona uhlelo lwemithambo yegazi "oluhlukile" noma "oluyisipele" olungasetshenziswa esikhundleni salokho. Lokhu yilokho okubizwa ngokuthi (i-Collateral Circulation) kwezokwelapha . Kalula nje, lokhu kufana nohlelo lwemvelo "lokudlula" emzimbeni wethu.

Ngakho-ke, iyini le ndlela ehlukile yemithambo yegazi (ukujikeleza kwegazi okuhlanganisiwe)?

Kalula nje, ukujikeleza kwegazi okuhlanganisiwe kuyisistimu yemithambo yegazi eyengeziwe noma "eyisipele" emzimbeni wakho. Lena yimithambo yegazi esiza ekuguquleni igazi uma umthambo wegazi oyinhloko, njengomthambo noma umthambo, uvaleka noma wonakala ngesizathu esithile. Lokhu kufana nendlela lapho umgwaqo omkhulu edolobheni uvaliwe, izimoto ezithatha imigwaqo eseceleni. Ngokuba nokugeleza kwegazi ngalezi zindlela ezihlukile, izitho ezibalulekile zingaqhubeka nokuthola umoya-mpilo nezakhamzimba ezizidingayo.

Lokhu kuyindlela yokuzivikela emangalisayo emzimbeni wethu. Cabanga ukuthi bekuzokwenzekani uma umthambo wegazi omkhulu uvaleka ngokuzumayo ngaphandle kwalezi zindlela ezihlukile!

Kusebenza kanjani lokhu kusakazwa kwe-collateral? Kuyamangalisa, akunjalo?

Yebo, kuyamangalisa ngempela. Lolu hlelo (lwe-Collateral Circulation ) lusebenza ngezindlela eziningana.

• Imithambo yegazi emincane esekhona: Sinenethiwekhi yemithambo yegazi emincane kakhulu, emincane exhunywe emithanjeni yethu yegazi eyinhloko. Ngaphansi kwezimo ezivamile, le mithambo yegazi ayisebenzi kakhulu, njengemigwaqo emincane engasetshenziswa. Kodwa-ke, lapho ukugeleza kwegazi kuya emthanjeni wegazi omkhulu kuphazamiseka, umzimba uyakubona lokhu. Ngemuva kwalokho, le mithambo yegazi emincane "engalali" iyanda kancane kancane, ivuleke, futhi iqala ukuthwala igazi eliningi.

• Ukwakheka kwemithambo yegazi emisha (i-Angiogenesis): Ngezinye izikhathi, lapho umthambo wegazi omkhulu uvaleka kancane kancane, umzimba wethu uyakuzwa lokhu. Uma uthola isignali yokuthi "akukho igazi elanele eligeleza lapha," umzimba uqala ukwakha imithambo yegazi emisha, emincane. Le nqubo ibizwa ngokuthi i-angiogenesis . Le mithambo emisha isiza ukuthwala igazi endaweni evalekile.

• Umphumela wokuzivocavoca: Ubuwazi ukuthi ukuzivocavoca okuvamile , njengokugijima noma ukuhamba ngokushesha, kungasiza ekuthuthukiseni ukugeleza kwegazi kule mithambo yegazi emisha?Kuvuselela i-angiogenesis. Lokhu kusho ukuthi ukuvivinya umzimba kungaqinisa lolu hlelo "lokusekelayo".

Ngakho-ke, yile ndlela umzimba wethu ozama ngayo ukubhekana nokuphazamiseka kokujikeleza kwegazi .

Ivame kangakanani le ndlela ehlukile yegazi (ukujikeleza kwegazi okuhlanganisiwe)? Ingabe wonke umuntu unayo?

Sonke sizalwa sinezinga elithile lokujikeleza kwegazi okubalulekile . Kodwa-ke, ubukhulu, inani, kanye nokusebenza kahle kwale mithambo yegazi eyengeziwe kungahluka kumuntu nomuntu. Abanye abantu banalolu hlelo oluthuthukisiwe kahle kakhulu, kanti abanye abanalo olwakhiwe kahle. Luyahlukahluka kumuntu nomuntu.

Kunezinhlobo ezintathu eziyinhloko zale mithambo yegazi ehlukile:

• Imithambo yegazi: Lena yimithambo yegazi emikhulu ethwala igazi elinomoya-mpilo lisuka enhliziyweni liye emzimbeni wonke.
• Ama-capillary: Lawa ayimithambo yegazi emincane kakhulu. Asakazeke njenge-mesh. Aletha umoya-mpilo nezakhamzimba emaseli futhi aqoqe imfucuza efana ne-carbon dioxide.
• Imithambo: Lena yimithambo yegazi ethwala igazi elingenawo umoya-mpilo , elicebile nge-carbon dioxide libuyele enhliziyweni lisuka ezingxenyeni ezahlukene zomzimba.

Ngakho-ke zonke izinhlobo ezintathu zemithambo yegazi, imithambo yegazi, imithambo yegazi, kanye nama-capillary, zingasebenza njengezindlela zokunikeza igazi ezihlukile.

Kukuziphi izimo zempilo lapho lokhu kujikeleza kwegazi okubalulekile kubaluleke kakhulu khona?

Lolu hlelo (lokujikeleza kwegazi okuhlanganisiwe) lungasetshenziswa futhi lusize ezimweni ezahlukene zezokwelapha ezivimbela ukugeleza kwegazi, okungukuthi, ukunciphisa ukugeleza kwegazi emithanjeni yegazi. Nazi izibonelo ezimbalwa:

• I-atherosclerosis : Lokhu kwenzeka lapho amafutha ne-cholesterol kwakheka ngaphakathi kwezindonga zemithambo yegazi, kunciphisa umthambo wegazi, kuvimbele ukugeleza kwegazi.
• Isifo Semithambo Yenhliziyo: Ukuhlaselwa yinhliziyo kubangelwa ukuvaleka kwemithambo yenhliziyo ehambisa igazi enhliziyweni.
• I-Ischemic Stroke: Lesi simo senzeka lapho umthambo wegazi ohambisa igazi ebuchosheni uvalekile noma kwakheka ihlule.
• Isifo Semithambo Engasogwini (i-PAD): Lesi sifo sibangelwa ukuncishiswa kwemithambo ehambisa igazi, ikakhulukazi emilenzeni. Esinye sezibonakaliso zalokhu ubuhlungu emilenzeni lapho uhamba.

Kodwa nansi into ebaluleke kakhulu okufanele uyikhumbule! Lolu hlelo (lokujikeleza kwegazi okuhlanganisiwe) luhlala luthinteka ukwehla kokuhlinzekwa kwegazi (i-Ischemia) okubangelwa yilezi zimo.Akunakuvinjelwa ngokuphelele. Ngoba, ngaphambi kokuba umthambo wegazi oyinhloko uvalwe ngokuphelele, lezi ziteshi ezihlukile kudingeka zikhule ngokushesha ngokwanele futhi zikwazi ukuthwala igazi elanele. Ngakho-ke, uma unezimo ezinjalo, noma ngabe unegazi elihlukile elihle, kufanele nakanjani ufune ukwelashwa. Lokhu kuwusizo nje, hhayi ikhambi eliphelele.

Kuthatha isikhathi esingakanani lokhu kusakazwa kwempahla ebambisene?

Uma lolu hlelo (lokujikeleza kwegazi okuhlanganisiwe) lusebenza, leyo mithambo yegazi emincane iyanda kancane kancane bese iqala ukuthwala igazi eliningi. Le mithambo yegazi ekhulisiwe ingase ikwazi ukunikeza igazi elijwayelekile izinyanga, mhlawumbe ngisho neminyaka.

Kodwa-ke, ngokuhamba kwesikhathi, ikakhulukazi njengoba sikhula, le mithambo yegazi ehlukile ingancipha kancane kancane, noma iqale ukuba mincane. Le nqubo ibizwa ngokuthi i-rarefaction . Lesi simo sivame kakhulu kubantu abanesifo senhliziyo nemithambo yegazi . Lapho le mithambo yegazi ehlukile incipha, ukusebenza kwayo kwehla. Ngemuva kwalokho, uma umthambo wegazi omkhulu uvaleka futhi, izimpawu zingaba khona.

Kukuziphi izingxenye zomzimba lapho le mithambo yegazi ehlukile (ukujikeleza kwegazi okuhlanganisiwe) ivame ukutholakala khona?

Lezi zinhlelo zokujikeleza kwegazi ezihlukile zingatholakala ezingxenyeni ezahlukene zomzimba wethu. Isibonelo:

• Isisu
• Izingalo
• Ubuchopho
• Izinyawo nemilenze
• Enhliziyweni (Enhliziyweni)
• Amaphaphu

Eqinisweni, lokhu (i-Collateral Circulation) kuyindlela umzimba oyisebenzisayo ukunqoba isithiyo ekugelezeni kwegazi. Kodwa-ke, njengoba kushiwo ngaphambili, lena akuyona indlela engenakugwenywa engavimbela ngokuphelele umonakalo obangelwa yizimo ezifana nesifo sohlangothi kanye nezifo ezifana ne- (PAD) . Ayikwazi futhi ukuvimba ngokuphelele ukuhlaselwa yinhliziyo noma isifo sohlangothi. Kodwa-ke, kwezinye izimo, kungaba usizo kakhulu, futhi kungasiza ngisho nokusindisa impilo.

Ayini amathemba alokhu esikhathini esizayo?

Abacwaningi bezokwelapha bayaqhubeka nokutadisha lokhu (ukujikeleza kwegazi okuhlanganisiwe) ngentshisekelo enkulu. Ikakhulukazi, kwenziwa ucwaningo mayelana nokuthi imithambo yokwenziwa ehlanganisiwe ingadalwa futhi isetshenziswe yini. Uma into enjalo iphumelela, kuzokwazi ukwandisa ikhono lomzimba lemvelo lokubhekana nezifo ezahlukahlukene eziphazamisa ukujikeleza kwegazi. Lelo ithemba elikhulu.

Ngakho-ke, yiziphi izinto ezibaluleke kakhulu okudingeka sizikhumbule kulokhu? (Umyalezo Wokuya Ekhaya)

Kulungile, ake sikhumbule ezinye zezinto ezibaluleke kakhulu esikhulume ngazo (i-Collateral Circulation) :

• Ukujikeleza kwegazi okuhlanganisiwe kuyindlela yemvelo "yokusekela" imithambo yegazi emzimbeni wethu.Uma umthambo wegazi omkhulu uvalekile, uyasiza.
• Lena yindlela yokuzivikela yomzimba. Ngezinye izikhathi ingaba usizo kakhulu futhi isindise ngisho nokuphila.
• Ukuvivinya umzimba njalo kusiza le mithambo yegazi ehlukile ukuthi ikhule.
• Kodwa-ke, lesi akusona isisombululo esiphelele sezifo. Uma unesifo esifana ne- (Atherosclerosis) , (Coronary Artery Disease) , (Stroke Risk), noma (PAD) , kufanele nakanjani ufune iseluleko sezokwelapha kanye nokwelashwa.
• Ukusebenza kwalezi zindlela ezihlukile kungase kwehle ngokuguga noma izimo ezithile zezokwelapha.
• Ukugcina indlela yokuphila enempilo , ikakhulukazi ukudla ukudla okunempilo kwenhliziyo nokuzivocavoca, kusiza ukugcina lolu hlelo oluhlukile, kanye nohlelo lonke lokujikeleza kwegazi, luphilile.

Ngakho-ke, imizimba yethu iyamangalisa ngempela, akunjalo? Kuyamangalisa ukuthi baklame kanjani izinhlelo eziyinkimbinkimbi kangaka ukuze bazivikele. Kodwa, nakuba kusiza lezo zindlela zemvelo zokuzivikela, kubalulekile futhi ukuthi sinakekele impilo yethu.

Imithambo yegazi ehlukile , izindlela ezengeziwe zegazi, Ukujikeleza kwegazi okuhlangene, ukujikeleza kwegazi, isifo senhliziyo, ukuvaleka kwemithambo yegazi, i-Angiogenesis
