Wake wacabanga ngokujulile ngendlela ukudla neziphuzo esizidlayo okunika ngayo imizimba yethu amandla? Ngemva kokumunca ukudla esikudlayo emathunjini ethu, lezo zakhi zomzimba aziyi ngqo emizimbeni yethu yonke. Konke kufanele kuqale kuyiswe esitshalweni esimangalisayo sokucubungula. Leso yisibindi sethu. Ngakho-ke, umgwaqo omkhulu, noma isango elikhulu, elithatha zonke lezi zinto kusukela ezindaweni ezifana namathumbu nesisu kuya esibindini yilo Mthambo We-Portal esikhuluma ngawo namuhla. Uma ungasebenzi kahle, wonke umzimba ungaphazamiseka. Ake sibheke ukuthi uyini, usebenza kanjani, nokuthi ungawugcina kanjani uphilile.
Kuyini i-Portal Vein kalula?
Kalula nje, i-Portal Vein iwumthambo wegazi okhethekile othwala igazi lisuka ezithweni eziningana ezinkulu esiswini sakho uliyise esibindini sakho. Ngokuvamile, imithambo emzimbeni wethu ithwala igazi lisuka ezithweni libuyele enhliziyweni. Kodwa lo mthambo we-Portal uhlukile kancane. Awuthwali igazi liye enhliziyweni, kodwa uliyisa esibindini.
Cabanga ngalokhu. Ukudla okudlayo kuyagaywa emathunjini, futhi izakhamzimba ezikutholayo zimuncwa egazini. Kodwa ngesikhathi esifanayo, ezinye izinto eziyingozi emzimbeni wethu (ubuthi) nazo zingangezwa egazini. Manje, uma leli gazi lithunyelwa ngqo kuwo wonke umzimba, ngeke libe lihle kangako, akunjalo?
Yilapho i-Portal Vein kanye neSibindi kusisiza khona. I-Portal Vein ifana nomgwaqo omkhulu oletha izinto zokusetshenziswa embonini enkulu. Isibindi yileyo mboni.
- Ukucutshungulwa kwezakhamzimba: Isibindi sicubungula ushukela, amavithamini, namaminerali egazini elivela emathunjini sibe izinto umzimba wethu ongazisebenzisa. Noma yikuphi okungaphezulu kugcinwe ukuze kusetshenziswe kamuva.
- Ukususa ubuthi: Futhi, izinto eziyingozi egazini, njengemithi eseleyo, zihlungwa yisibindi, zicutshungulwe zibe izinto ezingenangozi, bese zilungiselelwa ukususwa emzimbeni.
Ukuze kwenziwe le misebenzi ebalulekile, igazi elivela ezithweni zesisu kumele liqale lifinyelele esibindini. Lowo ngumsebenzi oyinhloko we-Portal Vein.
Lolu hlelo lwe-Portal Venous lusebenza kanjani?
I-Portal Vein ayisebenzi yodwa. Iyingxenye enkulu yesistimu enkulu. Sibiza lolu hlelo ngokuthi i-Portal Venous System. Lolu hlelo luqoqa igazi ezithweni eziningi ezibalulekile esiswini sethu. Lezi zitho yilezi:
- Amathumbu amancane
- Amathumbu amakhulu
- Isisu
- I-Pancreas
- Ubende
- Inyongo
Cabanga ngazo zonke lezi zitho ezincane zegazi esithweni ngasinye njengamagatsha omfula. Wonke la magatsha ayahlangana ukuze akhe umfula owodwa omkhulu. Lowo mfula omkhulu yi-Portal Vein. Bese lo mfula ugeleza uye "efektri enkulu" ebizwa ngokuthi isibindi.
Ngemva kokuba isibindi sesihlanze kahle leli gazi futhi sacubungula izakhamzimba, kudingeka libuyiselwe enhliziyweni. Lokhu kwenzeka ngesinye isimiso semithambo yegazi. Igazi liphuma esibindini bese lijoyina umthambo omkhulu obizwa ngokuthi i-Inferior Vena Cava, lapho liya khona liye e-atrium yesokudla yenhliziyo. Ukusuka lapho, liphonswa libuyele emzimbeni wonke.
Kalula nje, i-Portal Vein iyisango elikhethekile eliletha igazi esibindini ukuze lihlanzwe . Ngaphandle kwayo, umzimba wethu ubungeke ukwazi ukumunca kahle izakhamzimba noma ukususa ubuthi.
Yimiphi imithambo eyinhloko eletha igazi ku-Portal Vein?
Umthambo wesango wakhiwa ukuhlangana kweminye imithambo emikhulu eminingana. Lokhu kubizwa ngokuthi 'imifula', njengemifula yomfula. Lolu lwazi lungase lubonakale luyinkimbinkimbi kancane ngokwezokwelapha kuwe, kodwa leli thebula lenza kube lula ukuliqonda.
| Igama Lemithambo | Isitho esiyinhloko esithwala igazi |
|---|---|
| Umthambo we-Superior Mesenteric (SMV) | Igazi lilethwa lisuka emathunjini amancane nasezindaweni zamathumbu amakhulu. |
| Umthambo we-Splenic | Igazi lilethwa lisuka ebhodweni. |
| Umthambo we-Mesenteric ophansi | Igazi lilethwa lisuka ezingxenyeni ezisele zamathumbu amakhulu. |
| Imithambo Yesisu | Igazi liyakhishwa esiswini. |
| Imithambo Yesicanucanu | Kukhishwa igazi enyongweni. |
Umthambo we-portal wakhiwa ikakhulukazi ukuhlangana kwemithambo emibili, i-Superior Mesenteric Vein kanye ne-Splenic Vein.
Yiziphi izifo ezithinta i-Portal Vein?
Ngenxa yokuthi iwumthambo obaluleke kangaka, noma iyiphi inkinga ngayo ingaholela ezinkingeni ezinkulu zempilo. Kunezimo ezimbili eziyinhloko ezingabonakala.
| Isimo | Kuchazwe kalula |
|---|---|
| Umfutho wegazi ophezulu we-Portal | Lokhu kwenzeka lapho umfutho wegazi emthanjeni we-portal kanye nemithambo ehambisana nawo ukhuphuka . Njengoba nje ipayipi lamanzi livaliwe, umfutho ongaphakathi kwalo uyakhuphuka. Imbangela enkulu yalokhu yi-cirrhosis yesibindi. Lapho isibindi siba lukhuni futhi igazi lingasakwazi ukugeleza kuso kalula, umfutho ongaphakathi komthanjeni we-portal uyakhuphuka. Lesi yisimo esiyingozi kakhulu. |
| I-Thrombosis ye-Portal Vein | Lokhu kwenzeka lapho kwakheka ihlule legazi emthanjeni we-portal. Leli hlule legazi linganciphisa noma livale ngokuphelele umthambo. Lesi simo sivame kakhulu nakubantu abane-cirrhosis yesibindi kanye nezinkinga zokujiya kwegazi. |
Udokotela uzixilonga kanjani lezi zinkinga?
Uma udokotela wakho esola inkinga nge-portal vein, angase ancome ukuhlolwa okuningana.
- Ukuhlolwa kwegazi: Iphaneli Ephelele Yokusebenza Kwe-Metabolic (CMP) yokuhlola ukusebenza kwesibindi nezinso kanye ne-Complete Blood Count (CBC) ukuhlola izinto ezifana nokopha.
- I-Ultrasound Scan: Lokhu kungasetshenziswa ukubona ukuthi igazi ligeleza kanjani nge-portal vein, isivinini sayo, nokuthi ngabe kukhona yini amahlule egazi.
- I-Upper Endoscopy: Enye yezinkinga ezinkulu ze-portal hypertension ukuvuvukala kwemithambo esesiswini nasesiswini. Lokhu kungaqhuma futhi kophe igazi. I-endoscopy ihilela ukufaka ikhamera ngomlomo ukuhlola isimo sale mithambo.
Ngokusekelwe emiphumeleni yalezi zivivinyo, udokotela wakho uzonquma ukuthi yikuphi ukwelashwa okudingayo. Kungaba imithi, ukuhlinzwa okuncane, noma ukuhlinzwa okukhulu.
Ungawugcina kanjani umthambo we-portal ophilile?
Ungabona ukuthi impilo ye-Portal Vein ihlobene ngqo nempilo yesibindi. Ngakho-ke ukuze sigcine lo mthambo uphilile, sidinga ukunakekela isibindi sethu. Futhi sidinga nokugcina lonke uhlelo lwethu lokujikeleza kwegazi luphilile. Nazi ezinye izinto ezilula ongazenza ukuze wenze lokho.
1. Lawula izifo eziyisisekelo: Uma unezifo ezifana nesifo sikashukela, i-cholesterol ephezulu, umfutho wegazi ophakeme, njll., zilawule. Thatha imithi oyinikezwe udokotela wakho ngesikhathi. Uma lezi zifo zingalawulwa, zingalimaza isibindi nemithambo yegazi.
2. Yidla ukudla okunempilo kwenhliziyo: Ukudla okunempilo nokulinganiselayo akukhona nje ukwehlisa isisindo. Kuyitshalomali elikhulu ohlelweni lwethu lwenhliziyo nemithambo yegazi. Nciphisa ukudla okunamafutha amaningi, usawoti, noshukela, bese udla imifino eminingi, izithelo, ubhontshisi, kanye ne-fiber. Amaphethini okudla afana ne-"Mediterranean Diet" atholakale emuhle kakhulu kulokhu.
3. Ukuzivocavoca njalo: Ukuzivocavoca kuthuthukisa ukujikeleza kwegazi emzimbeni wonke. Zama ukuhamba, ukugijima, noma ukubhukuda okungenani imizuzu engama-30 ngosuku. Uma ungenaso isikhathi sokuzivocavoca kakhulu, hlala umatasa usuku lonke. Sukuma esihlalweni sakho uhambe kancane, bese usebenzisa izitebhisi esikhundleni se-lifti.
4. Ungaphuthelwa ukuya kudokotela wakho: Ngisho noma ungenazo izifo, bona udokotela wakho okungenani kanye ngonyaka ukuze ahlolwe ngokuphelele. Ngaleyo ndlela, uma kunenkinga, ingatholakala futhi yelashwe kusenesikhathi.
Ungakhohlwa ukuthi uma isibindi sakho siphilile, umthambo wakho we-portal cishe nawo uphilile. Into engcono kakhulu ongayenza ukuvikela isibindi sakho ukuyeka ngokuphelele noma ukunciphisa ukuphuza kwakho utshwala.
Umlayezo Wokuya Nawe Ekhaya
- I-Portal Vein iwumthambo wegazi oyinhloko othwala igazi lisuka ezithweni zohlelo lokugaya ukudla esiswini sethu liye esibindini.
- Isibindi sisebenza 'njengesihlungi', sicubungula izakhamzimba ezikuleli gazi futhi sisuse ubuthi. I-Portal Vein ibalulekile kulo msebenzi.
- Izifo ezifana ne-cirrhosis yesibindi zingabangela ukwanda kwengcindezi emthanjeni we-portal (i-Portal Hypertension) kanye namahlule egazi (i-Thrombosis). Lezi yizimo ezibucayi.
- Ungavikela isibindi sakho kanye nomthambo we-portal ngokulandela indlela yokuphila enempilo (ukudla okuhle, ukuvivinya umzimba) nokugwema utshwala.
- Uma unesifo sesibindi noma unemibuzo ngaso, umuntu ongcono kakhulu ongakhuluma naye ngaso udokotela wakho.
