Lub siab yog lub luag haujlwm rau ntau txoj kev ua hauv lub cev. Nws cov kev khiav dej num muaj xws li kev tswj cov rog thiab cov piam thaj, kom ntshav siab nrog cov enzymes uas pab tau, tsis muaj kev sib tov ntawm co toxins los ntawm sab nraud. Thaum raug rau sab nraud, thiab nrog rau kev mob hauv lub cev, muaj ntau yam hloov hauv cov nqaij hauv daim siab.
Dab tsi yog qhov txawv txav ntawm daim siab?
Feem ntau, daim siab lub cev ua rau daim tawv nqaij (lub cev nqaij daim tawv tseem ceeb ntawm hom kab mob hepatocytes) yog homogeneous, tsis muaj zog echogenic qauv, ntawm cov kab mob uas muaj ntshav thiab cov hlab ntsha.
Diffuse hloov hauv tus qauv ntawm lub siab qhia tias parenchyma hloov tag nrho. Tshaj li, nws tuaj yeem ua ob qho tib si tsis muaj kev hloov ntawm cov kev hloov hauv nruab nrab (mob pes tsawg txoj kev hloov hauv daim siab parenchyma) thiab qhov chaw muaj mob hnyav (parenchyma ntawm lub siab ntxiv echogenicity).
Diffuse hloov tau muaj tus cwj pwm txawv. Yog li, cov nram qab no hom kev hloov yog txawv:
- fibrous;
- sclerotic;
- hypertrophic;
- dystrophic;
- o.
Diffuse steatosis ntawm lub siab yog ib tug kab mob txuam nrog metabolic teeb meem hauv hepatocytes. Vim li ntawd, dystrophic hloov hauv lub siab yog cai, thiab muaj roj nyob hauv qhov chaw ntawm cov qoob loo hepatic.
Nrog ultrasound, muaj ib qho kev nce hauv daim siab, ib qho kev nce hauv nws cov echogenicity (qhov siv ntawm cov teeb liab reflected ultrasound) thaum tswj lub uniformity ntawm nws cov qauv. Nrog rau kev loj hlob ntxiv, txoj kev "tshua tshaj plaw" ntawm qhov parenchyma tshwm, uas qhia tau hais tias qhov pib ntawm kev txhim kho cov kab mob steatohepatitis thiab kab mob siab.
Ua rau diffuse daim siab hloov
Kev hloov hauv daim siab ntsws tuaj yeem tshwm sim rau ntau yam, vim tias muaj ntau yam tseem ceeb uas muaj feem cuam tshuam rau hauv lub nruab nrog cev. Cov no suav nrog:
- quav quav cawv;
- noj tshuaj;
- metabolic disorders;
- kev siv cov zaub mov tsis zoo-zoo;
- txhua yam kabmob kev mob, thiab lwm yam
Tsis tas li hloov cov kev hloov hauv lub parenchyma ntawm lub siab qhia tias muaj kab mob. Tab sis nyob rau hauv qee zaus lawv yuav ua tau rau qhov tsim nyog ntawm cov pathologies nram qab no:
- viral mob siab;
- kab mob siab cawv ;
- fatty degeneration ntawm lub siab;
- kab mob siab ntsws ntev ntev;
- cirrhosis;
- cholangitis , lwm yam zoo li
Cov tsos mob ntawm lub cev hloov ntawm diffuse
Diffuse hloov hauv cov ntaub so ntswg hauv daim siab yuav pib tsis muaj cov kev mob tshwm sim, tsis muaj kev cuam tshuam tus neeg. Feem ntau cov kev hloov puav leej raug kaw thaum tiv thaiv kev kuaj mob, nrog rau kev kuaj mob ultrasound.
Lub siab, vim nws loj thiab ceev, haum zoo qhia ultrasonic tsis, ces nws zoo scanned nrog ultrasound. Cov ntawv cim tseg (lo lus) ntawm qhov txawv ntawm daim tawv nqaij txawv yog cov kev tshwm sim hauv qab no thaum kawm:
- heterogeneous ntaub qauv;
- nce parenchyma echolarsity;
- qhov muaj cov chaw ntawm txo thiab nce echogenicity;
- nce siab loj;
- hloov cov qauv ntawm cov hlab ntsha.
Kev kho ntawm diffuse daim siab hloov
Kev kho ntawm diffuse cov kev hloov yog ua tiav tom qab tshab xyuas qhov tseeb uas ua rau
- kuaj ntshav;
- magnetic resonance imaging;
- angiography;
- keeb kwm kev kuaj ntawm lub siab daim ntaub, thiab lwm yam.
Ntxiv nrog rau kev tshuaj xyuas lub siab, nws yuav tsim nyog los kuaj xyuas tag nrho cov plab hnyuv.
Txoj kev kho mob yog nyob ntawm seb cov txiaj ntsim ntawm kev tshawb nrhiav pom dab tsi. Qee zaum, tsuas yog ua raws li kev noj haus thiab kev tiv thaiv ntawm kev coj cwj pwm phem, hauv lwm tus - noj tshuaj thiab kev pabcuam kev phais.
