Waiziva here nezve "tsinga dzeropa" dzinoshamisa dziri mumiviri yedu? (Collateral Circulation) Ngatikurukurei!

Nhasi tichataura nezvechimwe chinhu chinoshamisa uye chakakosha mumuviri wedu . Fungidzira, kana mugwagwa mukuru wauri kufamba nawo ukangoerekana wavharwa, zvakakosha sei kuva nemimwe migwagwa midiki yekufamba nayo. Saizvozvowo, mumuviri wedu, kana tsinga huru yeropa (tsinga yeropa) yakavharwa kana kukuvara, pane "imwe nzira" kana "backup" yetsinga yeropa inogona kushandiswa panzvimbo payo. Izvi ndizvo zvinonzi (Collateral Circulation) mukurapa . Zvichitaurwa zviri nyore, izvi zvakafanana ne "bypass" system yechisikigo mumuviri wedu.

Saka, chii chinonzi nzira iyi yekuwedzera tsinga dzeropa (collateral circulation)?

Zvichitaurwa zviri nyore, kutenderera kweropa mumuviri inzira yekuwedzera kana kuti "yekuchengetedza" yetsinga dzeropa mumuviri wako. Idzi ndidzo tsinga dzeropa dzinobatsira kutsausa ropa kana tsinga huru yeropa, senge tsinga kana tsinga, ikavharika kana kukuvara nekuda kwechimwe chikonzero. Izvi zvakafanana nenzira iyo kana mugwagwa mukuru muguta wakavharwa, mota dzinofamba mumigwagwa yedivi. Nekuva neropa richiyerera nenzira idzi dzakasiyana, nhengo dzinokosha dzinogona kuramba dzichigamuchira okisijeni nezvinovaka muviri zvavanoda.

Iyi inzira inoshamisa yekudzivirira muviri wedu. Fungidzira zvaizoitika kana tsinga huru yeropa ikangoerekana yavharika pasina nzira idzi dzakasiyana!

Kutenderera uku kwemari kunoshanda sei? Zvinoshamisa, handiti?

Ehe, zvinoshamisa chaizvo. Iyi sisitimu (yeCollateral Circulation ) inoshanda nenzira dzakasiyana-siyana.

• Mitsipa midiki yeropa iripo kare: Tine network yemitsipa midiki yeropa yakatetepa yakabatana netsinga dzedu huru dzeropa. Mumamiriro ezvinhu akajairwa, iyi haisi kushanda zvakanyanya, semigwagwa midiki isingashandiswi. Zvisinei, kana kuyerera kweropa kuenda kutsinga huru yeropa kukakanganiswa, muviri unoona izvi. Zvadaro, mitsipa midiki iyi "isina kurara" inokura zvishoma nezvishoma, inovhurika, uye inotanga kutakura ropa rakawanda.

• Kuumbwa kwetsinga itsva dzeropa (Angiogenesis): Dzimwe nguva, kana tsinga huru yeropa ikavharika zvishoma nezvishoma, muviri wedu unonzwa izvi. Painowana chiratidzo chekuti "hapana ropa rakakwana rinoyerera pano," muviri unotanga kuumba tsinga itsva, diki dzeropa. Maitiro aya anonzi angiogenesis . Mitsinga mitsva iyi inobatsira kutakura ropa munzvimbo yakavharika.

• Kushanda kwekurovedza muviri: Waizviziva here kuti kurovedza muviri nguva dzose , sekumhanya kana kufamba nekukurumidza, kunogona kubatsira kuvandudza kuyerera kweropa mutsinga itsva idzi dzeropa ?Zvinokurudzira angiogenesis. Izvi zvinoreva kuti kurovedza muviri kunogona kusimbisa iyi "backup system".

Saka, iyi ndiyo nzira iyo muviri wedu unoedza kubata nayo nekukanganiswa kwekufamba kweropa .

Nzira iyi yeropa yakasiyana (collateral circulation) yakajairika sei? Munhu wese anayo here?

Tose tinozvarwa tiine mwero wekufamba kweropa . Zvisinei, saizi, huwandu, uye kushanda zvakanaka kwetsinga idzi dzeropa zvinogona kusiyana kubva pamunhu kusvika pamunhu. Vamwe vanhu vane sisitimu iyi yakagadzirwa zvakanaka, nepo vamwe vasina kukura zvakanyanya. Inosiyana kubva pamunhu kusvika pamunhu.

Kune mhando nhatu huru dzetsinga dzeropa dzinoshandiswa:

• Tsinga dzeropa: Idzi ndidzo tsinga huru dzeropa dzinotakura ropa rine oxygen kubva pamoyo kuenda kumuviri wese.
• Macapillaries: Aya matsinga eropa madiki akanaka kwazvo. Akapararira semambure. Anoendesa okisijeni nezvinovaka muviri kumasero uye anounganidza marara akaita secarbon dioxide.
• Tsinga: Idzi ndidzo tsinga dzeropa dzinotakura ropa risina oxygen , rakapfuma necarbon dioxide kudzokera kumoyo kubva kumativi akasiyana emuviri.

Saka marudzi ese matatu etsinga dzeropa, tsinga dzeropa, tsinga dzeropa, uye capillaries, anogona kushanda senzira idzi dzekupa ropa.

Kutenderera uku kweropa kwakakosha zvikuru mumamiriro api ehutano?

Iyi sisitimu (Collateral Circulation) inogona kushanda uye kubatsira muzvirwere zvakasiyana-siyana zvinotadzisa kuyerera kweropa, kureva kuti, kuderedza kuyerera kweropa mutsinga dzeropa. Heano mimwe mienzaniso mishoma:

• Atherosclerosis : Apa ndipo apo mafuta necholesterol zvinoungana mukati memadziro etsinga, zvichiita kuti tsinga dzitete, zvichivhara kufamba kweropa.
• Chirwere chemwoyo: Kurwiswa kwemoyo kunokonzerwa nekuvharika kwetsinga dzemwoyo dzinopa ropa kumoyo.
• Ischemic Stroke: Chirwere ichi chinoitika kana tsinga dzinoendesa ropa kuuropi dzavharika kana kuti ropa ragwamba.
• Chirwere chePeripheral Artery Disease (PAD): Chirwere ichi chinokonzerwa nekutetepa kwetsinga dzinopa ropa, kunyanya kumakumbo. Chimwe chiratidzo cheizvi kurwadziwa kwemakumbo pakufamba.

Asi hechino chimwe chinhu chakakosha kurangarira! Iyi (Collateral Circulation system) system inogara ichikanganiswa nekudzikira kweropa rinopihwa (Ischemia) kunokonzerwa nemamiriro ezvinhu aya.Hazvigone kudzivirirwa zvachose. Nekuti, mutsinga huru yeropa isati yavharwa zvachose, nzira idzi dzinofanira kukura nekukurumidza uye dzikwanise kutakura ropa rakakwana. Saka, kana uine zvirwere zvakadaro, kunyangwe uine ropa rakanaka, unofanira kutsvaga kurapwa. Izvi zvinongobatsira chete, kwete mhinduro yakazara.

Kutenderera uku kwemari kunotora nguva yakareba sei?

Kana nzira iyi (collateral circulation) yatanga kushanda, tsinga diki dzeropa dzinokura zvishoma nezvishoma dzotanga kutakura ropa rakawanda. tsinga idzi dzakakura dzinogona kupa ropa rakajairika kwemwedzi, pamwe kunyange makore.

Zvisinei, nekufamba kwenguva, kunyanya sezvatinokura, idzi tsinga dzeropa dzinogona kutetepa zvishoma nezvishoma, kana kutanga kudzikira. Maitiro aya anonzi rarefaction . Dambudziko iri rinonyanya kuitika kuvanhu vane chirwere chemwoyo . Kana idzi tsinga dzeropa dzichitetepa, kushanda kwadzo kunoderera. Zvadaro, kana tsinga huru yeropa ikavharika zvakare, zviratidzo zvinowanzoonekwa.

Mitsipa iyi yeropa (collateral circulation) inowanzowanikwa muzvikamu zvipi zvemuviri?

Maitiro aya ekufambisa ropa anogona kuwanikwa munzvimbo dzakasiyana dzemuviri wedu. Semuenzaniso:

• Dumbu
• Maoko
• Uropi
• Tsoka nemakumbo
• Mumoyo
• Mapapu

Kutaura zvazviri, iyi (Collateral Circulation) inzira inoshandiswa nemuviri kukunda chipingamupinyi mukuyerera kweropa. Zvisinei, sezvambotaurwa, iyi haisi nzira isingakanganisike inogona kudzivirira zvachose kukuvara kunokonzerwa nemamiriro ezvinhu akadai sestroke nezvirwere zvakaita se (PAD) . Haikwanisewo kumisa zvachose kurwara kwemoyo kana sitiroko. Zvisinei, mune dzimwe nguva, inogona kubatsira zvikuru, uye inogona kutobatsira kuponesa hupenyu.

Ndezvipi zviri kutarisira izvi mune ramangwana?

Vaongorori vezvekurapa vari kuramba vachidzidza izvi (collateral circulation) nechido chikuru. Kunyanya, kutsvagurudza kuri kuitwa pamusoro pekuti mitsipa yesimbi inogona kugadzirwa here kana kushandiswa. Kana chinhu chakadaro chikabudirira, zvinokwanisika kuwedzera kugona kwemuviri kutsungirira zvirwere zvakasiyana-siyana zvinokanganisa kufamba kweropa. Ndiyo tariro huru.

Saka, ndezvipi zvinhu zvakakosha zvatinofanira kurangarira kubva pane izvi? (Mharidzo Yekuenda Kumba)

Zvakanaka, ngatiyeukei zvimwe zvezvinhu zvakakosha zvatataura nezvazvo (Collateral Circulation) :

• Kutenderera Kweropa muChwaro (Collateral Circulation) inzira yechisikigo ye "backup" yetsinga dzeropa mumuviri wedu.Kana tsinga huru yeropa ikavharika, idzi dzinobatsira.
• Iyi inzira yekudzivirira muviri. Dzimwe nguva inogona kubatsira zvikuru uye inotoponesa hupenyu.
• Kurovedza muviri nguva dzose kunobatsira kukura kwetsinga idzi dzeropa.
• Zvisinei, iyi haisi mhinduro yakakwana kuzvirwere. Kana uine chirwere chakadai se (Atherosclerosis) , (Coronary Artery Disease) , (Stroke Risk), kana (PAD) , unofanira kutsvaga mazano echiremba uye kurapwa.
• Kushanda kwenzira idzi dzimwe kunogona kudzikira nekukura kana mamwe mamiriro ehutano.
• Kuramba uine mararamiro ane hutano , kunyanya kudya chikafu chine hutano pamoyo uye kurovedza muviri, zvinobatsira kuchengetedza iyi nzira yekurapa, pamwe chete nehurongwa hwese hweropa, hwakanaka.

Saka, miviri yedu inoshamisa zvechokwadi, handiti? Zvinoshamisa kuti vakagadzira sei masisitimu akaomarara kudaro kuti vazvidzivirire. Asi, nepo vachibatsira nzira idzodzo dzekuzvidzivirira, zvakakoshawo kuti titarisire hutano hwedu.
