High Pressure koob txhaj tshuaj raws li kws kho mob ntsuam systems nyob rau hauv lub koom haum pab khoom, nrog rau cov X-ray tshuab, ceev zaj duab xis tshuab, duab intensifier thiab dag zoo ib tus neeg saib xyuas thiab cov kev loj hlob ntawm lub tsheb txhob sibtsoo tshwm sim. Nyob rau hauv lub 1980s, muaj ib qho kev tsis siv neeg koob txhaj rau angiography, thiab Jonsson li al. Invented lub stainless steel High Pressure koob txhaj tshuaj siv lub zog hauv paus ntsiab lus. Tsis ntev tom qab, Åke Gilund yees thawj High Pressure koob txhaj tshuaj thiab ob-txoj kev zaj duab xis changer thiab thov Nyob rau hauv angiography. Tam sim no, High Pressure koob txhaj tshuaj muaj tau lug siv nyob rau hauv ib tug ntau yam ntawm angiography, CT enhanced angiography thiab MR enhanced scan.
TSOOM: To taub cov kev sib raug zoo ntawm cov cua kub lub sij hawm ntawm lub High Pressure koob txhaj tshuaj sov ntaus ntawv thiab tus zoo neeg sawv cev kub, thiab xaiv cov CT lug txhim khu cov sij hawm noj ntawm kev txhaj tshuaj thiab txo cov kev phiv thiab tsis xis nyob. Txoj kev Ob tug sib txawv hom (Ⅰ, Ⅱ) kub siab koob txhaj tshuaj extraction kub tau 20,22,24 ℃ zoo neeg sawv cev 100ml, muab tso rau tom qab qhov kub thiab txias ntaus ntawv tom qab lub sij hawm, ntsig txog, nyob rau ntawm lub 2,5,10,20,30,40,50 , 60,80,100,120min tom qab cov kev ntsuas ntawm contrast neeg sawv cev kub thiab cov ntaub ntawv. Tau tib yam tej yam kev mob, lub hom Ⅰ High Pressure koob txhaj tshuaj zoo neeg sawv cev los ntawm lub sov ntaus ntawv tom qab cov cua kub kub yog siab tshaj Ⅱ; Ⅱ hom siab siab koob txhaj tshuaj tsawg kawg 60min curing neeg sawv cev kub yuav ncav cuag 32,5 ℃; ntsuas kub ntawm 20,22,24 ℃ Zoo neeg sawv cev daim ntawv thov hom Ⅰ kub siab koob txhaj tshuaj sov ntaus cua kub lub sij hawm rau 36 ℃ lub sij hawm yog 100,80,60min. Xaus Lub sib piv neeg sawv cev nyob rau hauv hom Ⅱ High Pressure koob txhaj tshuaj yuav tsis tau tib yam los yog nyob ze rau tib neeg kub li ntawm 2 xuab moos tom qab cov cua kub los ntawm tus sov ntaus ntawv. Thaum lub High Pressure koob txhaj tshuaj sov ntaus ntawv yog siv, tus zoo neeg sawv cev muaj peev xwm tsis cuag qhov zoo tshaj plaws txhaj kub nyob rau hauv ib tug luv luv lub sij hawm. Koob txhaj sov ntaus ntawv, lub ntsuas kub ntawm 20 ~ 24 ℃ zoo neeg sawv cev rhuab mus rau lub qub los yog ze rau tus tib neeg lub cev kub yuav tsum tau yam tsawg kawg yog 60 ~ 80min.
MR enhanced scan:
Sib Nqus resonance kub siab koob txhaj tshuaj yog tsim los siv rau cov magnetic resonance imager, yuav ua hauj lwm nyob rau hauv ib tug muaj zog sib nqus teb ib puag ncig. Txij li thaum lub osmotic siab ntawm lub magnetic resonance zoo neeg uas sawv cev qis tshaj hais tias ntawm lub iodine zoo neeg sawv cev, tag nrho cov nqi ntawm tus zoo neeg sawv cev txhaj yuav tsum tau tseem yog me me, ces nws muaj kev ruaj ntseg lug txhim khu nrog lub siab koob txhaj tshuaj. Daim ntawv thov ntawm magnetic resonance kub siab koob txhaj tshuaj yuav raug preset lub li qhov chaw, txhaj ceev, angiography pob sum thiab ncua lub sij hawm. Thiab daim ntawv thov ntawm high-siab koob txhaj yog conducive mus rau lub realization ntawm ceev ceev ua tsis taus pa tuav PP.
