Uyazi ukuthi amathumbu ethu enza umsebenzi ongakanani ukugaya kahle ukudla esikudlayo nokumunca izakhamzimba ezikunikezayo emizimbeni yethu? Kufana nefektri. Ngakho-ke, ukuze senze lo msebenzi kahle, amathumbu ethu adinga nokunikezwa kwegazi elihlanzekile, elinomoya-mpilo, nelicebile ngezakhamzimba okuqhubekayo. Namuhla, sizokhuluma ngomunye wemithambo yegazi eyinhloko enikeza lokho kunikezwa kwegazi okuyigugu. Kwezokwelapha, lokhu sikubiza ngokuthi i-Superior Mesenteric Artery . Nakuba igama liyinkimbinkimbi kancane, umsebenzi ulula kakhulu. Ake sibone ukuthi lokhu kuyini.
Kalula nje, iyini i-Superior Mesenteric Artery?
Lona umthambo obalulekile osuka ngqo emthanjeni wegazi oyinhloko nomkhulu kunayo yonke emzimbeni wethu, i-aorta . Cabanga ukuthi umbhobho wamanzi omkhulu kunayo yonke emzimbeni wethu yi-aorta. Ngakho-ke lo mthambo we-mesenteric ophakeme uwumbhobho omncane osuka lapho.
Igama elithi 'Superior' egameni lalo lisho 'ngaphezulu'. Lokhu kungenxa yokuthi litholakala ngaphezu kweminye imithambo ehambisa igazi emathunjini. Kukhona nomunye umthambo obizwa ngokuthi 'Inferior Mesenteric Artery'. Uhlinzeka ngegazi ezingxenyeni ezingezansi zamathumbu ethu amakhulu.
Ngakho-ke umsebenzi oyinhloko walo mthambo we-mesenteric ophakeme ukuhlinzeka ngegazi elinomoya-mpilo nelicebile ngezakhamzimba engxenyeni ephakathi yesimiso sethu sokugaya ukudla, okuyi-pancreas, amathumbu amancane, kanye namathumbu amakhulu. Lokhu kutholakala kwegazi kubalulekile ukuze lezi zitho zisebenze kahle.
Ikuphi le mithambo yegazi? Ikhula kanjani?
Lo mthambo utholakala phakathi nohlelo lwethu lokugaya ukudla, esiswini sethu. Uqala e-aorta bese ugijima ngemuva kwepancreas yethu.
Amagatsha amaningi amancane aqhamuka kulo mthambo oyinhloko, njengoba nje amagatsha eqhamuka esiqwini esiyinhloko somuthi. Igatsha ngalinye lihlinzeka ngegazi ezingxenyeni ezahlukene zesimiso sokugaya ukudla. Ake sibheke ukuthi ayini la magatsha ayinhloko nokuthi ahlinzeka ngegazi ezithweni zomzimba.
| Igama legatsha lomthambo (igatsha lomthambo) | Izitho/izingxenye ezihlinzeka ngegazi |
|---|---|
| Umthambo we-pancreaticoduodenal ophansi | Ekhanda le-pancreas kanye ne-duodenum (ingxenye yokuqala yamathumbu amancane) |
| Umthambo we-colic ophakathi | Ikholoni eguquguqukayo |
| Umthambo we-colic wesokudla | Ingxenye ekhuphukayo yamathumbu amakhulu (ikholoni ekhuphukayo) |
| Imithambo yeJejunal ne-Ileal | Izingxenye eziphakathi nendawo zokugcina zamathumbu amancane (iJejunum ne-Ileum) |
| Umthambo we-Ileocolic | I-appendix, ingxenye yokugcina yamathumbu amancane, kanye nengxenye yokuqala yamathumbu amakhulu (i-cecum) |
Okukhethekile ukuthi amagatsha omthambo we-mesenteric ophakeme kanye namagatsha omthambo we-mesenteric ophansi axhumene. Cabanga ngakho njengokuthi lapho umgwaqo omkhulu uvinjiwe, sithatha umgwaqo oseceleni ohlukile. Ngenxa yalezi zixhumanisi, noma ngabe umthambo owodwa uvinjiwe, igazi lisenganikezwa emathunjini ngezinga elithile. Lona umklamo omuhle wemvelo.
Yiziphi izifo ezithinta lo mthambo?
Njenganoma yimuphi omunye umthambo wegazi, umthambo we-mesenteric ophakeme ungathinteka yizimo ezithile zezokwelapha. Kubalulekile ukuzazi lezi, njengoba ngezinye izikhathi zingaba zimbi kakhulu.
| Isimo | Kuchazwe kalula |
|---|---|
| I-Mesenteric Ischemia | Lena inkinga evame kakhulu. Kwenzeka lapho i-cholesterol namafutha enqwabelana ngaphakathi kwemithambo yegazi (i-atherosclerosis) noma kwakheka ihlule legazi (i-thrombus) .Ukugeleza kwegazi emathunjini kuyancipha noma kuvimbeke ngokuphelele. Lesi yisimo esibucayi esidinga ukwelashwa okuphuthumayo. |
| I-Mesenteric Aneurysm | Okwenzekayo lapha ukuthi udonga lomthambo luyancipha futhi luqhume njengebhaluni. Lokhu kuyingozi ngoba ngelinye ilanga lokhu kuqhuma kungaqhuma futhi kubangele ukopha okukhulu esiswini. |
| Isifo se-Nutcracker | Lesi yisimo esingavamile. Njenge-nutcracker, umthambo wezinso wesobunxele ubhajwa phakathi komthambo we-mesenteric ophakeme kanye ne-aorta. Lokhu kuvimbela ukugeleza kwegazi elihlungiwe lisuka ezinso libuyele enhliziyweni. Lokhu kungabangela izimpawu ezifana nobuhlungu emhlane kanye negazi emchameni. |
| I-Superior Mesenteric Artery Syndrome | Lesi futhi yisimo esingavamile kakhulu. Kulesi simo, ingxenye yokuqala yamathumbu amancane (i-duodenum) inamathela phakathi komthambo we-mesenteric ophakeme kanye ne-aorta. Lokhu kuvimbela ukudla ukuthi kudlulele ngale kwesisu. Izimpawu ezifana nobuhlungu besisu nokuhlanza zingase zivele ngemva kokudla. |
Siyivikela kanjani le mithambo ebalulekile?
Eqinisweni, ukugcina uhlelo lokujikeleza kwegazi lomzimba wethu wonke luphilile kuyinto ebaluleke kakhulu, hhayi lo mthambo kuphela. Kunezinto ezimbalwa ezilula ongazenza ukuze wenze lokho.
- Isimiso esihle sokuzivocavoca: Vivinya umzimba okungenani izinsuku eziningana ngesonto. Ngisho nento efana nokuhamba, ukugijima, noma ukugibela ibhayisikili ilungile.
- Ukudla okunempilo kwenhliziyo: Nciphisa ukudla okunamafutha amaningi, i-cholesterol, nosawoti ngangokunokwenzeka. Yidla imifino eminingi, izithelo, ubhontshisi, nokudla okune-fiber eningi.
- Yeka ukubhema ngokuphelele: Ukubhema kuwumonakalo omkhulu emithanjeni yegazi.
- Gcina isisindo esinempilo: Kubaluleke kakhulu ukugcina isisindo esinempilo ngobude bakho. Uma ukhuluphele ngokweqile, zama ukunciphisa isisindo.
- Lawula ezinye izifo: Uma unezimo ezifana nesifo sikashukela, i-cholesterol ephezulu, noma umfutho wegazi ophakeme , landela imiyalelo kadokotela wakho, uphuze imithi yakho ngendlela efanele, futhi ulawule lezo zimo kahle. Lezi zifo zingalimaza imithambo yakho yegazi.
Kufanele ubonane nini nodokotela?
Uma unezinye zezimpawu ezilandelayo, ungazinaki. Ungachithi isikhathi, bona udokotela wakho ngokushesha.
- Ubuhlungu obukhulu, obungazelelwe besisu.
- Igazi elisendle noma igazi elisemchameni.
- Ukwehlisa isisindo ngaphandle kwesizathu.
Izimpawu ezinjengalezi zingaba uphawu lwesinye sezimo esixoxe ngazo ngenhla, ngakho-ke ukufuna ukwelashwa kusenesikhathi kungasiza ekuvimbeleni izimo ezingathi sína kakhulu.
Ekuphetheni, umthambo we-mesenteric ophakeme uyingxenye ebalulekile yokugcina uhlelo lwethu lokugaya ukudla luphilile futhi lusebenza kahle. Uma ukugeleza kwegazi kuvimbekile, kungavela izinkinga ezinkulu. Ngakho-ke, sonke masiqaphele ukugcina uhlelo lwethu lonke lokujikeleza kwegazi luphilile ngokwamukela indlela yokuphila enhle.
Umlayezo Wokuya Nawe Ekhaya
- I-Superior Mesenteric Artery iyi-artery enkulu ethwala igazi elinomoya-mpilo kanye nezakhamzimba ezithweni ezibalulekile njengamathumbu ethu kanye ne-pancreas.
- Uma kwakheka ama-fat deposits noma ama-blood clots ngaphakathi kwale artery (i-mesenteric ischemia) , ukugeleza kwegazi emathunjini kunganqamuka, okuholela esimweni esibucayi.
- Ungalokothi ungazinaki izimpawu ezifana nobuhlungu besisu obungazelelwe, obukhulu noma igazi esitulweni. Funa iseluleko sezokwelapha ngokushesha.
- Ukudla okunempilo, ukuvivinya umzimba njalo, ukugwema ukubhema, nokulawula izifo ezifana nesifo sikashukela kanye nomfutho wegazi ophezulu kungagcina lo mthambo kanye nomzimba wonke uphilile.
