Rat PLTx er en sofistikert Mikrokirurgiske prosedyre med et treningsprogram som er høy i pris og lang i varighet20. Kompleksiteten av rotte PLTx protokollen har forhindret forskere bruker denne dyremodell. Sammenlignet med full-size rotte LTx, presenterer rotte PLTx microsurgeon ikke bare en utfordring å en transplantasjon prosedyre, men også en utfordring å lever resection i en liten dyr. Derfor er en visualisert Mikrokirurgiske protokoll som beskriver hele prosedyren i detalj avgjørende for...

Aktuelle, er det et stort avvik mellom antall donert leveren organer og antall pasienter venter en donert lever. Mangel på leveren organer er et globalt problem. Å utvide donor bassenget, levertransplantasjon (LTx) og levende donor LTx ble utviklet for å bruke en delvis lever som pode1.
For ytterligere å undersøke mekanismen bak delvis levertransplantasjon (PLTx), har relevante dyremodeller vært etablert2,3,4,5. I rotte PLTx er lever lobes kappet i vivo og ex vivo å etterligne forholdene i levende donor LTx og dele LTx, henholdsvis i menneskelig. Et papir publisert i Tidsskriftet av visualisert eksperimenter presentert en detaljert protokoll med en 50% rotten PLTx bruker en ex vivo hepatectomy5. Imidlertid blitt rotte PLTx med en i vivo hepatectomy ikke har rapportert i visualisert litteratur.
I tillegg til forskjellen i vivo og ex vivo hepatectomies spiller teknikken av utfører en hepatectomy seg også en viktig rolle i å bestemme utfallet av PLTx. foreløpig i mange kirurgiske studier med rotta PTLx modellen, leveren lobes var resected etter å plassere en enkelt ligation på pedicle av leveren lobe2,3,6,7,8,9. Men å plassere en enkelt ligatur før reseksjon ikke er egnet for alle lever fliker, som forskjellige leveren lobes har forskjellige former og størrelser. En enkel ligation ved foten av den median lobe bærer en høy risiko for å forårsake en innsnevring vena cava, som til slutt kan påvirke utstrømming av delvis leveren pode10,11. Derfor kreves en oppdatering hepatectomy teknikk basert på kunnskap om rotte hepatic anatomien innen rotten PTLx.
I protokollen beskrevet i denne studien, ble en oppdatert fartøyet orienterte 70% hepatectomy innlemmet i prosedyren av rotte PLTx. Portal venene og hepatic arteriene venstre lateral lobe (LLL) og median lobe (ML) ble dissekert og delt individuelt før fjerning av leveren parenchyma. Deretter ble nedsatt venene LLL og ML samskrevet av piercing suturer. Ved å bruke personlige ligations og flere gjennomtrengende suturene i stedet for å plassere en enkelt ligation, kunne rest stump ml spredt over vena cava. Derfor ble innsnevring infrahepatic vena cava skyldes en surgical ligation unngått. I tillegg okklusjon av blodtilførselen LLL og ML av individuelle ligations før fjerning av leveren parenchyma redusert hastigheten på blø i rest leveren stump, og dermed minsker påvirkning av blodtap eksperimenter11.
For microsurgeons er det en betydelig utfordring å rekonstruere riktig hepatic arterien (PHA) for en lever pode på grunn av svært liten diameter på fartøyet. Selv om spørsmålet om nytt arterialization i LTx er virkelig nødvendig er fortsatt under debatten12,13,14, har mange Mikrokirurgiske teknikker for å rekonstruere arteria hepatic vært foreslått14 . Her introduserer vi en ny teknikk for re arterialization av leveren graften, som anastomoses felles hepatic arterien (CHA) til PHA forstørret på en ende-til-side-måte. Med denne ende-til-side-teknikken, er to hepatic arterier forbundet med en anastomose med større diameter. Jo større diameter på anastomose er, enklere hånd suturing er å utføre og jo større forbedring i patency av anastomose blir.

re-arterialized rat partial liver transplantation with an in vivo vessel-oriented 70% hepatectomy

Delt levertransplantasjon og levende leveren donor leveren transplantasjon ble utviklet i klinikken å utnytte leveren organer på en mer effektiv måte. For bedre å forstå mekanismen bak disse kirurgiske prosedyrer, ble en rotte delvis levertransplantasjon (PLTx) modell etablert for relevante kirurgisk studier. På grunn av kompleksiteten i rotte PLTx modellen kreves en protokoll med detaljerte beskrivelser. En artikkel publisert tidligere rapportert som var ex vivo hepatectomy brukes til å oppnå 50% rotten PLTx. I motsetning til denne protokollen introdusert vi et nytt arterialized PLTx med en i vivo 70% hepatectomy. En oppdatert fartøyet orienterte hepatectomy ble innlemmet i rotte PLTx å avgrense Mikrokirurgiske prosedyren. Portal venene og hepatic arterieene av det venstre lateral lobe og median flik var individuelt dissekert og samskrevet før fjerning av leveren parenchyma, og dermed redusere sannsynligheten for blødning i rest leveren stump. Videre ble en ende-til-side fartøyet anastomose mellom vanlige hepatic arterien og forstørret riktig hepatic arterien innført for å arterialize re hepatic arterien. Med denne ende-til-side fartøyet anastomose teknikken, ble diameteren på anastomose utvidet, og dermed redusere vanskeligheten av hånd Sutur og opprettholde en høy rate av anastomotisk patency. Videre var mansjett anastomose infrahepatic vena cava litt endret. En del av omkrets leveren parenchyma rundt vena cava mottaker ble bevart under mansjett anastomose å opprettholde tredimensjonal form av vaskulær lumen. Denne delen av leveren parenchyma ble fjernet etter å ha fullført anastomose. Med denne endringen, ble trinnet involverer plassering av oppholdet suturer utelatt, og dermed ytterligere redusere mansjett anastomose tiden. Ved å bruke denne protokollen av rotte PLTx, ble et lavt leveren enzym nivå, en intakt lever lobular arkitektur og en høy overlevelse oppnådd etter mikrokirurgi.

Totalt fullført 31 tilfeller av syngeneic arterialized rotten PLTx bruker denne protokollen. Alle mottakerne overlevde fram til slutten av observasjon. Kroppsvekten til mottakerne begynte å gjenopprette etter postoperativ dag (POD) 4. Skråningen av kroppsvekten var tilnærmet de en normal Lewis rotte POD 6 (Figur 8), som indirekte underforstått utvinning av mottakeren. Histologisk, en liten spredning av galle duct ble observert hos mottakerne, og lever lo...
