Wake wazibuza ukuthi, ngemva kokumunca amandla ekudleni esikudlayo, igazi elicebile ngezakhamzimba liyahlanzwa kanjani ngaphambi kokuba lisabalale emzimbeni wonke? Namuhla sizokhuluma ngomthambo wegazi obaluleke kakhulu ofihliwe esiswini sethu osiza kulo msebenzi. Ngumthambo we-Superior Mesenteric, owaziwa nangokuthi i-SMV ngamafuphi. Lokhu kuyingxenye ebalulekile yokusebenza kahle kwesistimu yethu yokugaya ukudla.
Kalula nje, uyini umsebenzi we-Superior Mesenteric Vein?
Cabanga ukuthi uhlelo lwemithambo yegazi esiswini sakho lufana nesihlahla. Le SMV ifana negatsha elikhulu kulowo muthi. Leli gatsha elikhulu lithola igazi elivela emagatsheni amancane (okungukuthi, emithanjeni yegazi emincane).
Umsebenzi oyinhloko walo mthambo ukuqoqa igazi elicebile ngezakhamzimba kodwa elingenawo umoya-mpilo ezithweni zomzimba ohlelweni lwethu lokugaya ukudla bese uliyisa esibindini.
Le nqubo yenzeka ngesistimu ekhethekile emzimbeni wethu. Siyibiza ngokuthi uhlelo lwesango lesibindi. Omunye wemithambo eyinhloko kulesi simiso yi-SMV. Lokhu kusho ukuthi izakhamzimba ezimuncwa emathunjini ethu zithuthwa ziye esibindini ukuze zihlanzwe ngaphambi kokuba zisakazwe emzimbeni wonke.
I-SMV iqoqa igazi ikakhulukazi kulezi zitho:
- Amathumbu amancane
- Amathumbu amakhulu
- Isisu
- I-Pancreas
- Isithasiselo
I-SMV iqoqa igazi kuzo zonke lezi zindawo bese ilidlulisela emthanjeni omkhulu nakakhulu obizwa ngokuthi i-portal vein. Uma sithatha isibonelo somuthi esikhulume ngawo ngaphambili, uma i-SMV iyigatsha elikhulu, umthambo we-portal ufana nesiqu salowo muthi. Lesi siqu sixhunywe ngqo esibindini sethu.
Ngemva kokuba leli gazi lifike esibindini, isibindi siyasihlunga, sisihlanze, bese sisilungiselela izidingo zomzimba. Bese kuthi, igazi lithunyelwe enhliziyweni. Lisuka enhliziyweni, igazi liya emaphashini ukuze lithathe umoya-mpilo, bese libuyela enhliziyweni ukuze lisakazwe kuwo wonke umzimba. Uyaqonda ukuthi le nqubo ibaluleke kangakanani?
Yimiphi imifula eletha igazi ku-SMV?
Sithe i-SMV ithola igazi elivela eqoqweni elincane lemithambo. Ake sibheke kalula leyo mithambo kanye nezitho eziqoqa igazi kuzo.
| Igama lomthambo omncane (i-Tributary Vein) | Izitho Ezikhishwe Amanzi |
|---|---|
| Imithambo yeJejunal neyeileal | I-jejunum ne-ileum, izingxenye zamathumbu amancane |
| Umthambo we-Ileocolic | I-Ileum, i-cecum, ne-caecum |
| Umthambo we-colic wangakwesokudla | Ikholoni ekhuphukayo |
| Umthambo we-colic ophakathi | Ikholoni eguquguqukayo |
| Umthambo wesisu nesokudla | Isisu |
| Imithambo ye-pancreaticoduodenal ephansi | I-Pancreas kanye ne-Duodenum |
Ikuphi esiswini le SMV?
Lo mthambo we-SMV utholakala ngaphakathi kwesisu sethu. Kalula nje, ungaphakathi kwesikhala esikhulu esiswini sethu esingaphansi kwesifuba nangaphezu kwe-pelvis, lapho kutholakala khona izitho ezibalulekile.
Iqala eduze kwekheji lethu lezimbambo. Ukusuka lapho, lo mthambo uhamba uye phezulu bese uhlangana nomthambo we-splenic eduze kwe-vertebra yokuqala ye-lumbar (L1) yomgogodla wethu ukuze wakhe umthambo we-portal oshiwo ngenhla.
Indlela lo mthambo ohamba ngayo ikhetheke kakhulu!
Ngokuvamile, umthambo nomthambo emzimbeni wethu kugijima eceleni, njengezimoto ezihamba ngazo zombili izindlela emgwaqweni. I-SMV isebenza ohlangothini lwesokudla lomthambo wayo ohambisanayo, umthambo we-mesenteric ophakeme. Ngenkathi umthambo uthwala igazi elinomoya-mpilo emathunjini, umthambo uthwala igazi elinothile ngezakhamzimba lisuka emathunjini liye esibindini.
Kodwa-ke, ngezinye izikhathi, ngenxa yesimo esenzeka ekuzalweni (i-malrotation) noma into efana nesimila esiswini, esicindezela izitho ezizungezile, lo mthambo ungadlula nangakwesobunxele somthambo.
Yiziphi izimo zezokwelapha ezithinta i-SMV?
Njenganoma yisiphi esinye isitho, kunezimo ezingathinta umthambo we-SMV. Kubalulekile ukuzazi lezi, njengoba ezinye izimo zingaba zimbi kakhulu futhi zidinga ukwelashwa okuphuthumayo.
Into ebaluleke kakhulu ukuthi, uma uzwa ubuhlungu besisu obungachazeki, obunzima, ungalokothi ubushaye indiva. Bonana nodokotela ngokushesha okukhulu.
Kunezimo ezimbili eziyinhloko ezithinta:
1. I-SMV thrombosis
Lokhu kwenzeka lapho kwakheka ihlule legazi ngaphakathi komthambo we-SMV. Lokhu kungaba yisimo esibi kakhulu.
- Uphawu oluyinhloko: Ubuhlungu besisu obungazelelwe nobunamandla yilona uphawu oluvame kakhulu.
- Ezinye izinhlobo: Kodwa-ke, kwabanye abantu, lobu buhlungu bungase bufike budlule izinsuku noma amasonto. Ngezinye izikhathi, lesi simo singase sibe khona ngaphandle kwezimpawu.
Ukuthola ukwelashwa kwalesi simo ngokushesha okukhulu kungasindisa impilo. Ngakho-ke, uma uzwa ubuhlungu obukhulu esiswini, kufanele uye eMnyangweni Wezimo Eziphuthumayo (ETU) wesibhedlela ngokushesha.
2. Umfutho wegazi ophezulu we-portal
Lokhu kusho ukuthi umfutho wegazi ohlelweni lwemithambo yegazi ye-portal esikhulume ngalo ngaphambili uyakhuphuka.
- Izimbangela: I-cirrhosis yesibindi kanye nokuqhekeka kwegazi yizona zimbangela eziyinhloko.
- Ubunzima: Lokhu kungabangela izinkinga ezisongela ukuphila, njengokuphuma kwegazi ngaphakathi.
Ukwelashwa kuhilela ukulawula izinkinga, futhi kwezinye izimo, ukuphambukisa ukugeleza kwegazi kuye ekwehliseni umfutho wegazi. Konke lokhu kunqunywa udokotela wakho.
Ukufunda ngezinto eziyinkimbinkimbi kangaka ngomzimba kungazwakala kukhungathekisa kancane. Kulungile. Uma udokotela wakho ekutshela ukuthi unesifo esihlobene nalokhu, ungesabi. Buza udokotela wakho ngokuphindaphindiwe nganoma yini ongayiqondi. Uzokuchazela konke ngamazwi alula. Lapho sazi okwengeziwe ngemizimba yethu, kulapho kuzoba lula khona ngathi ukwenza izinqumo ezifanele mayelana nempilo yethu.
Umlayezo Wokuya Nawe Ekhaya
- I-Superior Mesenteric Vein (SMV) iwumthambo wegazi omkhulu othwala igazi elicebile ngezakhamzimba lisuka emathunjini ethu nakwezinye izitho zohlelo lokugaya ukudla liye esibindini.
- Lena yingxenye ebaluleke kakhulu yesistimu yemithambo yegazi ethwala igazi esibindini.
- Ukuqhekeka kwegazi kulo mthambo (i-SMV thrombosis) kuyisimo esibi kakhulu. Ubuhlungu besisu obungazelelwe, obukhuluLesi yisibonakaliso esikhulu, futhi yisimo esidinga usizo oluphuthumayo lwezokwelapha.
- Umfutho wegazi ophezulu we-portal uwukwanda kwengcindezi kulesi simiso semithambo yegazi. Kungabangelwa yizimo ezifana nesifo sesibindi.
- Uma uzwa ubuhlungu besisu obungazelelwe, obukhulu ngaphandle kwesizathu esibonakalayo, ungabushayi indiva bese ubona udokotela ngokushesha noma uye eMnyangweni Wezimo Eziphuthumayo (ETU) wesibhedlela.
