Zithini iiPulmonary Veins? Masiyiqonde ngokulula.

Sonke siyazi ukuba intliziyo yinjini yomzimba wethu. Eli lungu lincinci elimpompa igazi emzimbeni wonke kwaye linika ubomi kwiseli nganye liyamangalisa ngokwenene. Kodwa ngaba ukhe weva ngenkqubo yemithambo yegazi ebaluleke kakhulu enceda intliziyo isebenze, ingakumbi leyo ibuyisela igazi elinomoya-mpilo ocociweyo emaphashini entliziyweni? Loo nkqubo yemithambo yegazi yinto esiyibiza ngokuba yimithambo yemiphunga, okanye imithambo yemiphunga . Ukwazi ngezi zinto kubaluleke kakhulu ukuze siqonde imizimba yethu.

Yintoni umahluko phakathi kwale mithambo yemiphunga kunye nemithambo yemiphunga?

Ngoku usenokuba nombuzo othi: "Xa sisithi imithambo, sihlala sicinga ngemithambo ethwala igazi elingcolileyo, oko kukuthi, igazi elinomoya-mpilo omncinci. Imithambo-luvo ithwala igazi elicocekileyo, elinomoya-mpilo omninzi. Ngoko ke yintoni ekhethekileyo ngale mimithambo?"

Ewe, uchanekile. Yiloo nto eyenzekayo kuyo yonke indawo emizimbeni yethu. Imithambo yegazi izisa igazi elingenaoksijini entliziyweni, kwaye imithambo yegazi ithwala igazi elineoksijini eliyityebileyo entliziyweni. Kodwa kwimiphunga, apho igazi litshintshiselana khona phakathi kwemiphunga nentliziyo, ibali litshintshile ngokupheleleyo. Nantsi into emangalisayo ngemizimba yethu!

Kalula nje, kukho umahluko omkhulu emibini:

1. Uhlobo lwegazi oluthwalwayo:

• Imithambo Yemiphunga: Le ithwala igazi elingenaoksijini (elibi) ukusuka entliziyweni ukuya emiphungeni.
• Imithambo Yemiphunga: Le ithwala igazi elineoksijini (elicocekileyo) ukusuka emiphungeni ukuya entliziyweni.

2. Icala lokuhamba kwegazi:

• Imithambo Yemiphunga: Ithwala igazi lisuka entliziyweni (lisiya emiphungeni).
• Imithambo Yemiphunga: Ithwala igazi elivela emiphungeni ukuya entliziyweni.

Makhe sijonge le theyibhile ukuze sicacise oku ngakumbi.

Yintoni umsebenzi wemithambo yemiphunga kwaye ifumaneka phi?

Cinga ngayo njengenkonzo yokuhambisa imithwalo. Imiphunga ifana 'neziko lokucoca igazi' emzimbeni wethu. Xa siphefumla, ioksijini esiyiphefumlayo yongezwa egazini, kwaye i-carbon dioxide egazini isuswa egazini ngemiphunga. Umsebenzi ophambili wale mithambo yemiphunga kukubuyisela le 'nxalenye ixabisekileyo' yegazi elicociweyo, elitsha elineoksijini 'kwiziko eliphambili lokusasaza igazi' elibizwa ngokuba yintliziyo.

Ezi ziphakathi kwemiphunga yethu nentliziyo yethu . Imithambo yegazi emincinci kwimiphunga yethu yasekunene neyasekhohlo iyadibana ize iphume kwimiphunga nganye njengemithambo emibini yemiphunga. Emva koko yonke le mithambo idibana ize idibane ne-atrium yasekhohlo yentliziyo. Oko kukuthi, igumbi elikwicala lasekhohlo lentliziyo.

Zingaphi imithambo yegazi esinayo?

Ngokwesiqhelo, uninzi lwethu (malunga nama-60%-70%) lunemithambo emine yemiphunga.

• Zimbini ukusuka kwiphaphu lasekunene.
• Ezimbini zisuka kwiphaphu lasekhohlo.

Kodwa abanye abantu banokuba nezifo ezintathu okanye ezintlanu. Esi asisosifo salo naluphi na uhlobo, kwaye asiyonto yokoyika. Lutshintsho nje oluncinci kwindlela umzimba wethu owenziwe ngayo. Kwizonyango, oku sikubiza ngokuba yi "Anatomical variations". Olu tshintsho alubangeli monakalo ekusebenzeni komzimba.

Ulwakhiwo lwemithambo yemiphunga

Nazi imithambo emine eqhelekileyo yemiphunga:

• Umthambo we-pulmonary olungileyo: Ukhupha igazi elivela kwiindawo eziphezulu neziphakathi zomphunga wasekunene.
• Umthambo wemiphunga ongaphantsi kwesandla sasekunene: Ukhupha igazi elivela kwinxalenye esezantsi yomphunga wasekunene.
• Umthambo we-pulmonary ophambili ngasekhohlo: Ukhupha igazi elivela kwinxalenye ephezulu yomphunga wasekhohlo.
• Umthambo wemiphunga ongaphantsi kwesobunxele: Ukhupha igazi elivela kwinxalenye esezantsi yomphunga wasekhohlo.

Le mithambo mine ivuleka ngokwahlukeneyo iye kwi-atrium yasekhohlo yentliziyo. Igazi elineoksijini lingena kwi-atrium yasekhohlo ngezi zithuba zine. Emva koko igazi liya kwi-ventricle yasekhohlo, apho liphonswa khona liye emzimbeni wonke nge-aorta.

Utshintsho kwimithambo yemiphunga

Abanye abantu banokuba notshintsho oluncinci kwisakhiwo semithambo yabo yamaphaphu. Ezinye zezi nguqu azinabungozi kwaye zisempilweni. Kodwa ezinye zinokuba ziimeko ezinzima ezichaphazela ukusebenza kwentliziyo.

Utshintsho olungenabungozi

Ezi azibangeli ngxaki emzimbeni, kuba ekugqibeleni igazi elinomoya-mpilo omninzi liya ngqo kwi-atrium esekhohlo.

• Isiqu esiqhelekileyo esisecaleni lasekhohlo: Kulapho imithambo emibini evela kwiphaphu lasekhohlo idibana khona ize idibane ne-atrium yasekhohlo njengetyhubhu enye. Kufana neendlela ezimbini ezidibanayo ukuze zenze enye.
• Umthambo wepulmonary wasekunene oncedisayo: Kule meko, kunokubakho omnye umthambo ukongeza kwimithambo emibini eqhelekileyo kwicala lasekunene, oko kuthetha ukuba kunokubakho imithambo emithathu iyonke.

Utshintsho olukhulu oluchaphazela ukusebenza kwentliziyo

Ezi zihlala zizifo zentliziyo ezizalwa nazo. Zibangelwa kukuvaleka okanye utshintsho kwindlela igazi elineoksijini elihamba ngayo ukuya kwi-atrium yasekhohlo.

• Ukubuya Kwemithambo Yemiphunga Epheleleyo (i-TAPVR): Le yimeko enzulu kakhulu. Kule meko , akukho nanye imithambo yemiphunga edibana ne-atrium yasekhohlo yentliziyo. Endaweni yoko, yonke le mithambo idibana ne-atrium yasekunene yentliziyo. Oku kubangela ukuba igazi elineoksijini eninzi lidibane negazi elingenaoksijini. Iintsana ezinale meko kufuneka zenze utyando ukuze ziphile.

• Ukubuya Kwemithambo Yemiphunga Engaphelelanga (i-PAPVR): Kule meko, ubuncinane umthambo omnye wemiphunga uqhagamshelwe kwi-atrium yasekhohlo, nto leyo evumela igazi elicocekileyo ukuba lihambe liye emzimbeni. Nangona oku kungengobungozi njenge-TAPVR, aba bantu basenokufuna unyango. Ngamanye amaxesha, le meko isenokungafunyaniswa de kube mdala.

Ezinye iimeko ezichaphazela imithambo yemiphunga

Ukongeza kwiziphene zokuzalwa, kukho nezinye iimeko ezininzi zempilo ezichaphazela imithambo yemiphunga.

• Ukuvaleka kwemithambo yemiphunga:Umthambo ungavaleka ngenxa yesifo somhlaza emiphungeni okanye entliziyweni.
• I-pulmonary vein stenosis: Ukuncitshiswa kwemithambo enye okanye ngaphezulu. Kwabantu abadala, le meko ngamanye amaxesha inokwenzeka njengesiphumo esingesihle se-catheter radiofrequency ablation, unyango lokubetha kwentliziyo okungahambelaniyo.
• Ukuvaleka kwemithambo yegazi emithanjeni: Ukuqhekeka kwegazi emthanjeni. Oku kuxhaphake kakhulu kubantu abanomhlaza wemiphunga okanye abaye bafakelwa imiphunga.
• Uxinzelelo oluphezulu lwemithambo yegazi emithanjeni: Uxinzelelo oluphezulu kule mithambo yegazi ngenxa yokungasebenzi kakuhle kwecala lasekhohlo lentliziyo.

Ulwalamano phakathi kwe-atrial fibrillation kunye nemithambo ye-pulmonary

Le mivimbo yemiphunga, ingakumbi apho idibana khona ne-atrium yasekhohlo yentliziyo, yindawo ephambili yokuqala kwe-atrial fibrillation , okanye i-A-Fib, imeko apho intliziyo ibetha ngokungacwangciswanga. Yiyo loo nto oogqirha besebenzisa unyango olukhethekileyo kule mivimbo yemiphunga xa benyanga i-A-Fib.

Uyijonga njani imeko yabo yempilo?

Ukuba ugqirha wakho ukrokrela ukuba kukho ingxaki kwimithambo yakho yamaphaphu, unokucebisa iimvavanyo ezininzi, ezifana nezi:

• I-X-reyi yesifuba
• I-Echocardiography (ukuskena kwentliziyo)
• Iskeni ye-MRI
• Iskeni ye-CT

Uyigcina njani imithambo yakho yamaphaphu isempilweni?

Ukuba ugqirha wakho ukufumanise ukuba unesifo semithambo yemiphunga, kubalulekile ukulandela imiyalelo yakhe. Amaxesha amaninzi, ezi ngxaki zibangelwa zezinye iimeko zentliziyo okanye zemiphunga. Ke ngoko, kubalulekile ukunyanga imeko esisiseko ngokufanelekileyo nokuhlala phantsi kweliso likagqirha rhoqo.

Thetha ngokukhululekileyo nogqirha wakho malunga nezinto ezikuxhalabisayo kunye neempawu zakho. Mbuze ngeendlela onokulawula ngazo imeko yakho ekhaya.

Imithambo yemiphunga yinxalenye yomzimba ethuleyo, kodwa ibaluleke kakhulu ekugcineni ubomi bethu buphila. Ukuzazi ezi ndlela kunceda kakhulu ekunyamekeleni impilo yethu iyonke.
