Ngaba uyazi ngalo mthambo wegazi umangalisayo oya esibindini? (I-Portal Vein) Masithethe ngale nto!

Ngaba wakha wacinga ngemithambo yegazi engaphakathi emizimbeni yethu? Mhlawumbi awukacingi kangako ngayo, akunjalo? Kodwa, namhlanje siza kuthetha ngemithambo yegazi ebaluleke kakhulu nekhethekileyo emizimbeni yethu. Oku kubizwa ngokuba yiPortal Vein . Ngokuchanekileyo, oku kufana nendlela enkulu ethwala igazi lisuka kwizitho ezahlukeneyo ngaphakathi esiswini sethu ukuya esibindini.

Yintoni le portal vein?

Ngamafutshane, umthambo wakho wesango ngumthombo wegazi othwala igazi lisuka kwizitho ezininzi esiswini sakho ukuya esibindini sakho. Isibindi sakho emva koko sicoca eli gazi, silihluze, silicubungule, size silibuyisele entliziyweni yakho. Ukusuka apho, igazi liphamputhwa kuwo wonke umzimba wakho.

Ngokwesiqhelo, njengoko sisazi, imithambo yegazi ithwala igazi ukuya entliziyweni. Nangona kunjalo, imizimba yethu inenkqubo ekhethekileyo ebizwa ngokuba yiHepatic Portal System okanye iPortal Venous System . Oku kwahlukile kancinci kwinkqubo eqhelekileyo. Imithambo yegazi kule nkqubo ayithwali igazi ngqo entliziyweni, kodwa ithwala igazi esibindini. Umthambo wegazi oyintloko kuloo nkqubo yiPortal Vein .

Ukuze uqonde oku, cinga ngako "njengomngxuma" kumzila womdyarho. Lo mthambo wesango yindlela eya esibindini. Isibindi sifana "nendawo yokuma emngxunyeni" apho igazi lenza khona "ulondolozo" olufunekayo.

Xa igazi lingena kwi-portal vein, lizele zizondlo ekufuneka umzimba wethu uzisebenzise ngaphambi kokuba uzisebenzise. Likwaqulethe iityhefu , ezizinto eziyingozi ezingafunwa ngumzimba. Ngoko ke isibindi "siyalilungisa" eli gazi. Oko kukuthi, liguqula izondlo zibe yindlela umzimba onokuyisebenzisa ngoko nangoko okanye uyigcine. Kwangaxeshanye, lisusa iityhefu.

Emva kolu "hlengahlengiso," igazi lilungele ukubuyela entliziyweni. Ngoko ke, liphuma esibindini lize lihlangane nomthambo omkhulu obizwa ngokuba yi-Inferior Vena Cava , apho liya khona kwigumbi eliphezulu lasekunene lentliziyo, i-Right Atrium .

Yintoni umsebenzi wePortal Vein?

Umsebenzi ophambili we-portal vein yakho kukuthwala igazi lisuka kwizitho ezisesiswini sakho liye esibindini sakho ukuze licutshungulwe. Ngoko ke, kubalulekile kwinkqubo ye-portal venous. Ngumnyango ophambili wegazi ukuze lingene esibindini. Zonke ezinye imithambo emincinci ekugqibeleni ziyadibana kwaye ziqhagamshelane nale portal vein. Ngoko ke, ukuze yonke inkqubo isebenze kakuhle, le portal vein kufuneka ibe sempilweni kwaye isebenze kakuhle.

Iintlambo ezizisa igazi kwi-portal vein

Kukho amasebe aliqela anika igazi kwi-portal vein, oko kukuthi, ayayijoyina. Lawa ngala:

• Umthambo weMesenteric oPhezulu (SMV): Lo mthambo uthwala igazi elivela kumalungu aliqela asembindini wesisu sakho, ingakumbi amathumbu akho amancinci.
• Umthambo we-Splenic:Oku kutsala igazi kwi-spleen yakho.
• Umthambo weMesenteric ongaphantsi: Lo uthwala igazi kwiindawo ezithile zamathumbu akho amakhulu.
• Imithambo Yesisu: Le ithwala igazi esiswini sakho.
• Imithambo yeCystic: Le ithwala igazi elivela kwinyongo yakho.

Igazi eliqokelelwayo kuzo zonke ezi veins liya esibindini nge-portal vein.

Iphi le portal vein?

Umthambo wakho wesango uqala emva kwentamo yepancreas yakho naphambi kwe -vena cava yakho engaphantsi . Ukusuka apho, udlulela kwindawo ebizwa ngokuba yi-porta hepatis , okanye i-liver hilum. Le porta yindawo apho imithambo yegazi nezinye izakhiwo zingena zize ziphume khona esibindini.

Yintoni isakhiwo se-portal vein?

Umthambo wakho we-portal wenziwa apho umthambo wakho we-mesenteric ophambili (SMV) kunye nomthambo we-splenic zidibana khona. Ukusuka apho, umthambo we-portal uhamba uye phezulu uye ngasekunene, emva komthambo wakho we-hepatic , ude ufike esibindini.

Njengoko ingena kwi-liver hilum, i-portal vein yakho iyahlukana ibe ngamasebe amabini. La ngamasebe akho e-Left Portal Vein kunye ne -Right Portal Vein . La masebe ayahlukana abe ngamasebe amancinci aya kwiindawo ezahlukeneyo zesibindi.

Iinguqu kwiAnatomy

Ngamanye amaxesha, utshintsho oluncinci kolu lwakhiwo lunokubonwa. Olunye lotshintsho oluqhelekileyo lubizwa ngokuba yi -portal vein trifurcation . Kulapho i-portal vein yahlulahlula ibe ngamasebe amathathu endaweni yamabini njengoko ingena esibindini. La masebe ngala:

• Umthambo wePortal yasekhohlo
• Umthambo wePortal yangaphambili ngasekunene
• Umthambo wePortal yangasemva ekunene

Olu tshintsho alunabungozi. Nangona kunjalo, kubalulekile ukwazisa ugqirha wakho ngalo ngaphambi kokuba wenze utyando oluthile kunye neenkqubo zonyango. Oogqirha baza kwenza uvavanyo lwemifanekiso ngaphambi kotyando ukuze bafunde ngesakhiwo somzimba wakho baze batshintshe inkqubo yotyando njengoko kufuneka.

Ingakanani i-portal vein?

Ngokwesiqhelo, umthambo wakho wesango umalunga neesentimitha ezisi-8 (cm) ubude kwaye ungabi ngaphezu kweemilimitha ezili-13 (mm) ububanzi.

Ziziphi iimeko ezinokuchaphazela umthambo we-portal?

Kukho iimeko ezininzi eziphambili zempilo ezinokuchaphazela le portal vein:

• Uxinzelelo lwegazi oluphezulu kwi-Portal: Oku kukunyuka koxinzelelo lwegazi kwi-portal vein nakumasebe ayo. Le yingxaki enkulu ye -cirrhosis yesibindi .
• I-Portal Vein Thrombosis: Oku kwenzeka xa ihlwili legazi lincipha okanye livala umthambo we-portal okanye elinye lamasebe awo. Le meko idla ngokuchaphazela abantu abane-cirrhosis yesibindi okanye ingxaki yokuxinana kwegazi.

Khumbula, ungoyiki xa ufunda ngezi meko. Eyona nto ibalulekileyo kukulandela iingcebiso zonyango.

Uvavanyo oluqhelekileyo olujonga impilo yomthambo we-portal

Ukuba ugqirha wakho urhanela ukuba kukho ingxaki nge-portal vein, angenza olunye okanye ngaphezulu kwezi vavanyo:

• Iphaneli Epheleleyo Ye-Metabolic (CMP): Oku kujonga ukusebenza kwesibindi sakho kunye nezintso.
• Ubalo lweGazi olupheleleyo (CBC): Oku kunceda ekuqinisekiseni ukuba kukho ukopha kwangaphakathi okubangela uxinzelelo lwegazi oluphezulu kwi-portal.
• Uvavanyo lwe-ultrasound: Olu vavanyo lusetyenziselwa ukubona indlela igazi elihamba ngayo kwinkqubo yemithambo yegazi ye-portal.
• I-Upper Endoscopy: Oku kwenzelwa ukujonga ukopha kwamathumbu (GI), okunokuba yingxaki ye-portal hypertension.

Ziziphi iindlela zonyango eziqhelekileyo?

Ugqirha wakho uza kukucebisa unyango olufanelekileyo ngokusekelwe kwiziphumo zovavanyo. Iindlela zonyango zinokwahluka kakhulu, kuxhomekeke kwingxaki engundoqo. Ezi zinokubandakanya enye okanye ezingaphezulu kwezi zilandelayo:

• Amayeza

Enye into encinci: Ngaba iHepatic Portal Vein kunye neHepatic Veins ziyafana?

Ewe, la magama mabini ngamanye amaxesha anokubangela ukudideka kancinci. I-Hepatic Portal Vein iyafana ne -Portal Vein ebesithetha ngayo ixesha elide. Nangona abantu abaninzi beyibiza nje ngokuba yi-"portal vein," eminye imithombo yezonyango ikwayibhala njenge-"hepatic portal vein." Omabini la magama abhekisa kumthambo wegazi omnye. Igama elithi "hepatic" lithetha into enxulumene nesibindi.

Nangona kunjalo, kulula ukubhidanisa amagama athi "i-hepatic portal vein" kunye "ne-hepatic veins" (ngaphandle kwegama elithi "portal"). Imithambo yesibindi yingqokelela yemithambo emithathu ethwala igazi ukusuka esibindini ukuya kwi-vena cava engaphantsi . Ngoko ke, ngelixa i-hepatic portal vein ithwala igazi *lisiya* esibindini, imithambo yesibindi ithwala igazi *liphuma* esibindini. Uyayazi?
