Anastomosis Portocaval rite te otinga ki ngā raruraru me te tātaritanga o te kaiao

To tatou tinana kua he pūnaha whakaaro-i roto i te tino pai o te tohanga. I roto i te take o ngā raruraru i roto i tetahi o te tohanga hei utu kē te tari, meinga nei e te aroaro o anastomoses. I tua atu, i ētahi wā tautuhi enei collaterals tohu haumanu o etahi mate.

E wehea venous oko toto tangata ki ngā rōpū e toru matua: te pūnaha o te rua tomokanga, raro me runga uaua tuwhera. Ia o enei rōpū whakarato te matamua o te toto i etahi wāhi o te tinana. I waenganui ia ratou, i reira e he maha o pūhui e kua karangatia e portocaval me kava anastomoses caval. Na reira, kua puta ki te tetahi o nga pūnaha, pērā i blockage o nga uaua, na e tika ana ki te aroaro o ta'ero ora matamua venous te.

Na tango i te titiro ofi ange anastomoses portocaval. Ko pūhui o te rua tomokanga (v porta.) Na raro o runga ranei venous tuwhera (v iho et pai iahoki.) A, ka te wāhi e whai ake nei ratou:

- te pū kai raro. Ko te toto i te rua tomokanga e tomo te uaua puku, e he whānui anastomose ki esophageal. uaua Esophageal, i tahuri, rere ki te uaua unpaired me hemiazygos e rerengia ana ki te v. iahoki matua pai;

- tōu. kawea te matamua o te toto i roto i roto i ngā mātāpuna e toru i te runga, waenganui, me wahi o raro rawa o reira. rere atu i te wahi o runga ki te raro rua mesenteric, waenganui i te toto - ki te iliac ā, me te pae hopea i te raro - i roto i te sex ā-(ka huaina i roto i te iliac ā-). Noatia, i roto i te matotoru o te tōu e hono ratou, ka hanga i anastomoses portocaval;

- mārōrō taiepa puku (a tawhio noa te mowhiti pito). anastomosis matatini, te puna o e ko te uaua o ngā pūnaha e toru katoa. Portal rua he rua pito e kua whakaritea i roto i te ate paihere porohita. Mai i te iahoki vena cava pai i roto i te anastomosis o runga ngā epigastrium, engari no te mea o te vena cava iho - epigastrium raro Vienna;

- tākihi capsule. I roto i tenei rohe, i te pūhui o te rua mesenteric iho (i te rua tomokanga) me uaua tākihi (i te raro o te tuwhera).

Me ahau mea e kore e anake anastomoses portocaval reira. I etahi wahi uru te runga me raro vena cava iahoki. E huaina taua pūhui kava anastomoses caval. E toru o ratou:

- he mārōrō, taiepa puku. Haunga anastomosis ki te rua tomokanga, te raro me te tuwhera o runga whānui me e hono tahi i te tahi;

- plexus vertebral. I roto i te anastomoses tuarā rua runga ki te rohe o te pūnaha rua, upoko me te kaki runga tuwhera, me te i roto i te wahi o raro - ki uaua lumbar o te iahoki vena cava iho. Ko te kupu, i hanga te anastomosis e te plexus vertebral;

- tinana. Lumbar iahoki (iho iahoki vena cava) me unpaired me hemiazygos iahoki (vena cava pai).

Te tikanga mea ta'ero matamua whakakorekore. Hei tauira, i roto i te syndrome o takawhita portal ko te tūranga tātaritanga nui anastomoses portocaval. Ko te meka Ko e i roto i te aroaro o tenei mate, he tokomaha o nga faaiteraa haumanu hono ki a ratou. He Kei te toto i varices esophageal, me te i te tōu. Ko te tohu matarohia ko te "upoko kakaru". faaite te reira i ano i runga i te taiepa puku mārōrō, me te whakaputa rua anastomosing. Ko tenei katoa e tika ana ki te meka i te mea o te pēhanga nui haere i roto i te toto tomokanga rua e rerengia ana i roto i ara e wātea ana katoa ki reira. Ko te take mō te takawhita tomokanga he mate ate, pērā i cirrhosis, kakā, me ētahi atu pāpaka neoplastic.

Ko te kupu, ko te aroaro o anastomoses ko te wāhi tino nui i roto i te mahi o te tinana. tākaro rātou i te wāhi tino hira i roto i te maha tukanga mate, a he tino nui mō te whakatau motuhake i te tinana o ngā raruraru, me mo te tātaritanga o etahi pathologies.
