Uyazi ukuthi sinenethiwekhi yemithambo yegazi esakazeke emizimbeni yethu. Lezi zifana nemigwaqo edlula ezweni. Eminye ifana nemigwaqo emikhulu, eminye ifana nemigwaqo emincane eseceleni. Kodwa kulesi simiso semithambo, abantu abaningi banomthambo owodwa kuphela, okhethekile kancane, futhi obaluleke kakhulu. Namuhla sikhuluma ngalo mthambo abantu abaningi abangakaze bawuzwe obizwa ngokuthi umthambo we-Azygos.
Kalula nje, iyini i-Azygos Vein?
Cabanga ukuthi lena yi-venous enkulu egijima ohlangothini lwesokudla lwesifuba sakho, eduze kakhulu nomgogodla wakho. Ukuze kube sobala, itholakala ngaphakathi kwesifuba sakho (isifuba). Le vein idlala indima ebaluleke kakhulu ohlelweni lokujikeleza kwegazi emzimbeni wethu.
Umsebenzi wayo oyinhloko ukuqoqa igazi eliphelelwe umoya-mpilo, noma "elingcolile" lisuka ngemuva kwesifuba sakho kanye nesisu bese uliyisa enhliziyweni. Ngaphambi kokuya enhliziyweni, leli gazi liqoqwa ku-vena cava ephezulu, omunye wemithambo emikhulu emzimbeni wethu. Ukusuka lapho, igazi liya e-atrium efanele yenhliziyo. Ngemva kokuya enhliziyweni, igazi liphinde ligcwaliswe umoya-mpilo, "lihlanzwe" bese liqala ukujikeleza kuwo wonke umzimba.
Uhlelo lwemithambo ye-azygos luyindaba enkulu!
Lo mthambo we-Azygos awuwona umthambo owodwa. Ufana nekhanda lohlelo lonke `(uhlelo lwemithambo yegazi oluyi-azygous)`. Kuneminye imithambo emincane eminingana kulolu hlelo. Into ebaluleke kakhulu ngalolu hlelo ukuthi lusebenza njengoxhumano olwengeziwe , noma umzila 'wokudlula', phakathi kwemithambo emibili emikhulu emzimbeni wethu, i-`inferior vena cava` (umthambo oyinhloko othwala igazi ohlangothini olungezansi) kanye ne-`superior vena cava` (umthambo oyinhloko othwala igazi ohlangothini oluphezulu).
Cabanga ukuthi yomibili imigwaqo emikhulu eya eColombo ivinjiwe yizimoto. Bekungaba usizo kangakanani ukube bekukhona enye indlela yokudlula izimoto engasetshenziswa? Yileyo ndlela lolu hlelo olusebenza ngayo. Uma omunye waleyo mithambo emibili emikhulu uvinjiwe noma uvalekile ngandlela thile, igazi lingageleza liye enhliziyweni ngalolu hlelo lwe-Azygos. Kwezokwelapha, lokhu sikubiza ngokuthi "i-anastomosis".
Ake sibheke amanye amalungu amabili ayinhloko alolu hlelo.
| Igama lomthambo | Incazelo elula |
|---|---|
| Umthambo we-hemiazygos oyisesekeli | Iqala ezikhaleni eziphakathi kwezimbambo zakho, igijimele ohlangothini lwesobunxele lomgogodla wakho, bese ekugcineni ithululela emthanjeni we-azygos. |
| Umthambo we-Hemiazygos | Lokhu kwakheka ngokuhlangana kweminye imithambo emincane eminingana, njengemithambo emgogodleni kanye nemithambo engaphansi kwezimbambo. Lo mthambo ubuye uqoqe igazi ekugcineni liye emthanjeni we-Azygos. |
Kalula nje, le mithambo emibili emincane ifana nemifula emibili emincane. Yomibili le mifula iyageleza futhi ihlangane ibe umfula omkhulu obizwa ngokuthi i-Azygos. Bese lowo mfula omkhulu uyahamba bese uhlangana ube ulwandle olukhulu olubizwa ngokuthi i-'superior vena cava'.
Lo mthambo uhluke kanjani kweminye imithambo?
Nansi into ekhethekile. Ngokuvamile, imithambo emzimbeni wethu ihlelwe ngababili . Lokho kusho ukuthi uma kukhona umthambo ohlangothini lwesokudla, kukhona nowokwesobunxele. Kodwa indlela umthambo we-azygos ohlelwe ngayo ihlukile kancane. Iningi labantu linomthambo we-azygos owodwa ohlangothini lwesokudla. Uyedwa. Kodwa akuvamile kakhulu, abanye abantu bangakha imithambo emibili ye-azygos ngenkathi bekhula esibelethweni sikamama. Leso yisimo esivamile.
Ngakho-ke kukhulu kangakanani lokhu?
Lo mthambo uvame ukuba ngu-1 cm ububanzi. Kalula nje, ulingana nebhethri le-AAA esilisebenzisa kuma-flashlight kanye nezilawuli ezikude.
Lo mthambo wenziwe ngani?
Njengeminye imithambo yegazi, lena ifana nepayipi eligobekayo elinodonga olunezendlalelo ezintathu.
- Ingqimba engaphakathi: Lokhu kwakhiwe uhlobo lweseli olubizwa ngokuthi amaseli e-endothelial. Lawa akhiqiza amakhemikhali asiza imithambo yegazi ukuthi ifinyele futhi ivuleke.
- Ingqimba ephakathi: Lokhu kwakhiwe ngemisipha ebushelelezi. Lokhu kuvumela umthambo ukuthi uguquguquke kakhulu.
- Ingqimba engaphandle: Lokhu kwakhiwe izicubu ezixhumeneyo ezibizwa ngokuthi `(collagen)` kanye `(elastin).` Lokhu kunikeza imithambo amandla nokunwebeka.
Yiziphi izinkinga nezimo ezithinta umthambo we-azygos?
Ngokuvamile, asivamile ukuba nezinkinga ngalo mthambo ekuphileni kwethu kwansuku zonke. Kodwa-ke, kunezimo ezithile lapho ungalimala khona noma umsebenzi wawo ungashintsha.
1. Ukwanda noma ukuvuvukala komthambo: Uma ukugeleza kwegazi kuvimbekile ngenxa yokwanda komfutho wegazi noma ukuvaleka komthambo, umthambo we-azygos ungavuvukala noma uvuvuke.
2. Ukulimala: Ezingozini ezinkulu, ikakhulukaziLo mthambo ungaqhekeka noma uqhekeke ezimweni ezifana nezingozi zezimoto, ukuwa usuka phezulu, noma ukushaywa kanzima esifubeni ngenkathi udlala imidlalo. Lesi yisimo esiyingozi kakhulu.
3. Ukulimala ngesikhathi sokuhlinzwa: Okunye ukuhlinzwa kwesifuba kungalimaza lo mthambo. Futhi, izinkinga ezivela kumadivayisi afana nama-pacemaker afakwe enhliziyweni zingathinta lo mthambo.
Ezimweni ezinjalo, umfutho wegazi emithanjeni ungakhuphuka noma wehle ngokweqile.
Ukuhlolwa ukuthola ukuthi kunenkinga yini
Uma udokotela wakho esola inkinga ngalo mthambo, angase ancome ukuhlolwa okuhlukahlukene ukuze kuqinisekiswe.
| Igama lokuhlolwa | Kwenzekani? |
|---|---|
| I-Arteriogram noma i-Venogram | Kufakwa idayi ekhethekile emithanjeni bese kuthathwa uchungechunge lwezithombe ze-X-ray. Lokhu kuvumela igazi ukuthi ligeleze kahle. |
| I-X-ray yesifuba | Lokhu kungakunikeza umbono oqondile uma kukhona umehluko omkhulu ngesimo noma ngobukhulu bomthambo. |
| Ukuskena kwe-CT | Lokhu kuvumela izithombe ezinemininingwane eminingi, ezinobukhulu obuthathu zezitho kanye nemithambo ngaphakathi kwesifuba. |
| Ukuskena kwe-MRI (i-MRI) | Lokhu kuvumela izithombe ezicacile zezicubu ezithambile zomzimba kanye nemithambo yegazi. |
Uphatha kanjani umonakalo?
Uma lo mthambo wonakele ngenxa yengozi ethile noma esinye isizathu bese uqala ukopha, odokotela bazothatha isinyathelo ngokushesha. Kungase kudingeke bavule isifuba bese benza inqubo yokuhlinzwa (i-thoracotomy) ukuze banciphise ingcindezi esifubeni futhi basuse igazi eliqongelelekile.
Abanye abantu bazalwa benezinkinga ezithile zokuzalwa kulo mzila. Abantu abanjalo bangase babe sengozini yokuthola izimo ezihlobene nobende noma isifo senhliziyo sokuzalwa. Kodwa-ke, lezi azivamile.
Yini ongayenza ukuze ugcine uhlelo lwakho lwezinzwa luphilile?
Le mikhuba izokusiza kakhulu ukugcina hhayi nje kuphela umthambo we-azygos, kodwa futhi nohlelo lwakho lonke lokujikeleza kwegazi luphilile.
- Yidla ukudla okunempilo okuhle. Nciphisa ukudla okunamafutha amaningi, usawoti kanye noshukela ngangokunokwenzeka.
- Vivinya umzimba njalo. Ngisho nento elula njengokuhamba imizuzu engama-30 ngosuku yanele.
- Phuza amanzi anele. Kubaluleke kakhulu ukuphuza okungenani amalitha amabili kuya kwamathathu amanzi ngosuku.
- Uma unomfutho wegazi ophakeme, lawula kahle. Thatha imithi oyinikezwe udokotela wakho ngesikhathi.
- Uma ubhema, yeka namuhla. Ukubhema kuwumonakalo omkhulu kakhulu ongawenza emithanjeni yakho.
Umthambo we-azygos uyiqhawe elithule kodwa elibaluleke kakhulu emzimbeni wethu. Uma uneminye imibuzo ngawo, noma uma unemibuzo mayelana nempilo yakho, umuntu ongcono kakhulu ongakhuluma naye udokotela womndeni wakho.
Umlayezo Wokuya Nawe Ekhaya
- Umthambo we-azygos umthambo omkhulu ogijima ohlangothini lwesokudla lwesifuba sakho, eduze komgogodla wakho.
- Umsebenzi wayo oyinhloko ukuthwala igazi elingenawo umoya-mpilo lisuka ngemuva kwesifuba nesisu liye enhliziyweni.
- Uma umthambo oyinhloko uvalekile, lolu hlelo lwemithambo lusebenza njengendlela eyengeziwe (yokudlula) ukuze igazi ligeleze.
- Lo mthambo ungonakala ezingozini ezinkulu, ngakho-ke kubalulekile ukufuna iseluleko sezokwelapha nganoma yikuphi ukushaywa okukhulu esifubeni.
- Ukulandela indlela yokuphila enempilo kuyindlela engcono kakhulu yokugcina yonke imithambo yakho iphilile.
