Wakambozvibvunza here kuti, mushure mekunge tatora simba kubva muchikafu chatinodya, ropa rine zvinovaka muviri rinocheneswa sei risati rapararira mumuviri wese? Nhasi tichataura nezvetsinga yeropa inokosha zvikuru yakavanzwa mudumbu medu inobatsira pabasa iri. NdiSuperior Mesenteric Vein, inozivikanwawo seSMV muchidimbu. Ichi chikamu chakakosha chekushanda zvakanaka kwegadziriro yedu yekugaya chikafu.
Zvichitaurwa zviri nyore, basa reSuperior Mesenteric Vein nderei?
Fungidzira kuti nzira yeropa iri mudumbu mako yakaita semuti. Iyi SMV yakaita sebazi guru riri pamuti iwoyo. Bazi guru iri rinogamuchira ropa kubva kumatavi madiki (ndiko kuti, tsinga diki dzeropa).
Basa guru retsinga iyi kuunganidza ropa rine zvinovaka muviri zvakawanda asi risina okisijeni kubva munhengo dziri mudumbu redu roriendesa kuchiropa.
Maitiro aya anoitika kuburikidza nehurongwa hwakakosha mumuviri wedu. Tinohudaidza kuti hepatic portal system. Imwe yetsinga huru muhurongwa uhwu iSMV. Izvi zvinoreva kuti zvinovaka muviri zvinotorwa kubva muura hwedu zvinotakurwa kuenda kuchiropa kuti zvicheneswe zvisati zvaparadzirwa mumuviri wese.
SMV inounganidza ropa kubva munhengo idzi:
- Ura hudiki
- Ura hukuru
- Dumbu
- Pancreas
- Chinyorwa Chekuwedzera
SMV inounganidza ropa kubva munzvimbo idzi dzose yoriendesa kune imwe tsinga yakakura inonzi portal vein. Kana tikatora muenzaniso wemuti watakambotaura, kana SMV iri bazi guru, tsinga ye portal yakafanana nehunde yemuti iwoyo. Hunde iyi yakabatana zvakananga nechiropa chedu.
Kana ropa iri rasvika muchiropa, chiropa chinochisefa, chinochichenesa, uye chinochigadzirira zvinodiwa nemuviri. Zvadaro, ropa rinotumirwa kumoyo. Kubva pamoyo, ropa rinoenda kumapapu kunotora okisijeni, uye rozodzoka kumoyo kuti riparadzirwe mumuviri wese. Unonzwisisa here kukosha kwekuita uku?
Ndezvipi zvitubu zvinounza ropa kuSMV?
Takati SMV inogamuchira ropa kubva mutsinga diki. Ngatimbotarisai tsinga idzodzo nenhengo dzavanotora ropa kubva kwadziri.
| Zita retsinga diki (Tributary Vein) | Nhengo Dzemuviri Dzakabviswa Mvura |
|---|---|
| Tsinga dzeJejunal nedzeIleal | Jejunum neileum, zvikamu zveura hudiki |
| Tsinga yeIleocolic | Ileum, cecum, uye caecum |
| Mutsinga wecolic wekurudyi | Mudumbu unokwira |
| Tsinga yepakati pecolic | Karoti yakachinjika |
| Tsinga yemudumbu yekurudyi | Dumbu |
| Tsinga dzepancreaticoduodenal dzakaderera | Pancreas neDuodenum |
SMV iyi iri kupi mudumbu?
Mutsinga uyu weSMV uri mukati medumbu redu. Zviri nyore, uri munzvimbo yakakura mudumbu redu iri pasi pechipfuva uye pamusoro pechiuno, uko kune nhengo dzinokosha.
Inotangira pedyo nembabvu dzedu. Kubva ipapo, tsinga iyi inofamba ichikwira yobatana netsinga yesplenic iri pedyo ne lumbar vertebra yekutanga (L1) yemusana wedu kuti igadzire tsinga ye portal yataurwa pamusoro apa.
Mafambiro anoita tsinga iyi akasiyana zvikuru!
Kazhinji, tsinga netsinga mumuviri wedu zvinofamba pamwe chete, sezvinoita mota dzinofamba munzira mbiri. SMV inomhanya kurudyi rwetsinga yayo inoenderana nayo, iyo superior mesenteric artery. Kunyange zvazvo tsinga iyi ichitakura ropa rine oxygen kuenda kumatumbo, tsinga iyi inotakura ropa rine zvinovaka muviri kubva mumatumbo kuenda kuchiropa.
Zvisinei, dzimwe nguva, nekuda kwechirwere chinoitika pakuzvarwa (malrotation) kana chimwe chinhu chakaita sebundu mudumbu, richidzvanya nhengo dzakapoteredza, tsinga iyi inogonawo kupfuura nekuruboshwe rwetsinga.
Ndezvipi zvirwere zvinokanganisa SMV?
Kufanana nedzimwe nhengo dzese dzemuviri, kune zvimwe zvirwere zvinogona kukanganisa tsinga yeSMV. Zvakakosha kuziva izvi, sezvo zvimwe zvirwere zvinogona kunge zvakakomba uye zvinoda kurapwa nekukurumidza.
Chinhu chinonyanya kukosha ndechekuti, kana uchinzwa kurwadziwa kwakanyanya mudumbu, usambozviregeredza. Enda kuna chiremba nekukurumidza sezvinobvira.
Kune mamiriro maviri makuru anokanganisa:
1. Kupera kweropa muropa (SMV thrombosis)
Apa ndipo panoumbwa ropa rakagwamba mukati metsinga yeSMV. Ichi chinogona kuva chirwere chakakomba zvikuru.
- Chiratidzo chikuru: Kurwadziwa kwakanyanya mudumbu kamwe kamwe ndicho chiratidzo chinowanzoitika.
- Mamwe marudzi: Zvisinei, kune vamwe vanhu, kurwadziwa uku kunogona kuuya kwopera kwemazuva kana mavhiki. Dzimwe nguva, chirwere ichi chinogona kunge chiripo pasina zviratidzo.
Kurapwa chirwere ichi nekukurumidza kunogona kuponesa hupenyu. Saka, kana uchinzwa kurwadziwa kwakanyanya mudumbu, unofanira kuenda kuchipatara cheEmergency Department (ETU) nekukasika.
2. Kukwira kweropa kwakanyanya padivi remuviri (portal BP)
Izvi zvinoreva kuti BP iri mu portal venous system yatakataura nezvayo kare inowedzera.
- Zvikonzero: Kuora kwechiropa uye kuumbwa kweropa ndizvo zvinonyanya kukonzera.
- Kuoma: Izvi zvinogona kukonzera matambudziko anotyisidzira hupenyu, akadai sekubuda ropa mukati memuviri.
Kurapa kunosanganisira kudzora matambudziko uye, mune dzimwe nguva, kutsausa kuyerera kweropa kuti kuderedze BP. Izvi zvese zvinosarudzwa nachiremba wako.
Kudzidza nezvezvinhu zvakaoma kudaro nezvemuviri kunogona kukuremera zvishoma. Hazvina kuipa. Kana chiremba wako akakuudza kuti une chirwere chine chekuita neizvi, usatya. Bvunza chiremba wako kakawanda nezvechero chausinganzwisisi. Iye achakutsanangurira zvese nemashoko akareruka. Patinonyanya kuziva nezvemiviri yedu, zvichava nyore kwatiri kuita sarudzo dzakakodzera nezvehutano hwedu.
Mharidzo Yekuenda Nayo Kumba
- Mutsinga weropa weSuperior Mesenteric (SMV) itsinga huru yeropa inotakura ropa rine zvinovaka muviri kubva muura hwedu nedzimwe nhengo dzemudumbu kuenda kuchiropa.
- Ichi chikamu chakakosha kwazvo che portal venous system chinopa ropa kuchiropa.
- Kugwamba kweropa mutsinga iyi (SMV thrombosis) chirwere chakakomba zvikuru. Kurwadziwa kwemudumbu kamwe kamwe, kwakakombaIchi chiratidzo chikuru, uye mamiriro ezvinhu anoda rubatsiro rwechiremba rwekukurumidzira.
- Kukwira kweropa mumuviri (portal hypertension) kunowedzera kumanikidzwa kweropa mutsinga iyi. Kunogona kukonzerwa nemamiriro ezvinhu akadai sechirwere chechiropa.
- Kana muine kurwadziwa kwakakomba mudumbu kamwe kamwe pasina chikonzero chakajeka, musazviregeredza uye onai chiremba nekukasika kana kuenda kuchipatara cheEmergency Department (ETU).
