Angiography: uas yog, ib tug piav qhia ntawm cov txheej txheem thiab nta

Cov neeg mob kev txom nyem los ntawm cov kab mob ntawm lub plawv thiab cov hlab ntsha yauv tsis tu ncua kev soj ntsuam kev tshawb fawb. Initial mob ntawm lub pathology tso cai rau qha thiab muab tso rau qhov tseeb mob, thiab kev soj ntsuam ntawm lub puab pab qhia ntxiv rau hauv lub xeev ntawm lub cev thaum lub sij hawm txoj kev kho thiab yog ib tug tiv thaiv kev ntsuas rau cov kev loj hlob ntawm cov teeb meem. Ib tug uas nquag siv txoj kev xeem ntawm cov hlab plawv system kab mob - angiography. Yuav ua li cas yog diagnostically tseem ceeb los qhia manipulation thiab yuav ua li cas nws yog ua, nws yog suav tias yog nyob rau hauv tsab xov xwm.

tag nrho

Thaum lub embodiment ntawm lub tswv yim ntawm cov tsos ntawm cov angiography nws coj ntau tshaj li 30 xyoo tom qab lub fact, raws li cov physiologist Behterev voiced lub thought: "Yog hais tias muaj yog kev daws teeb meem uas tsis dhau X-ray beams, nws yuav tsum tau sau nrog kua xws hlab ntsha thiab yees duab." Yuav kom manipulation tau ua ntau thiab zoo siv, nws muaj plaub ntau xyoo lawm.

Cov neeg mob uas cov kws kho sai, xav: "angiography - yog dab tsi?" Qhov no txoj kev ntawm mob ntawm tus mob thiab leeg tshav permeability uas yog tau siv X-ray zoo nrog. Tus txheej txheem tso cai rau kom ntsuam xyuas hauv qab no tsis:

• ntshav txaus tus nqi;
• vascular qhov chaw;
• lub xub ntiag ntawm congenital anomalies;
• narrowing;
• tsim ntawm circuitous txaus paths;
• mob ntawm cov hlab ntsha uas ntxiv zog rau hlav.

Qhov twg tus txheej txheem ua?

Diagnostic chaw zov me nyuam (nqaim los dav profile) thiab cov tsev kho mob nruab nrog chaw tshwj xeeb rau angiography.

Ntawm no tag nrho tej yam kev mob ntawm asepsis. Nyob rau hauv lub chaw yog tus tsim nyog cov khoom:

• Angiography - ntaus ntawv muaj apparatus rau moj ntsuam xyuas ntawm lub xeev ntawm cov hlab ntsha (cov hlab ntsha, cov leeg, cov hlab ntsha, lymphatic hlab ntsha);
• fluorographic ceev lub koob yees duab;
• ntaus ntawv, lub hom phiaj uas yog nqa tawm X-ray multishot thiab yeeb yaj duab.

Nyob rau hauv lub heev tshwj xeeb diagnostic chaw zov me nyuam ua CT angiography. Qhov no txoj kev tso cai rau koj kom tau ib tug dlaim phaj duab ntawm cov hlab ntsha hauv lub xeev (nyob rau hauv kom meej), thiab yog li ntawd yuav tsum tau siv qhov tseeb tshaj kiag li lawm.

kev tshawb fawb hauv paus ntsiab lus

Nyob rau hauv cov ntshav txog ntsha uas yog tsim nyog los xyuas thiab soj ntsuam muab radiopaque yeeb tshuaj, ib tug derivative ntawm iodine. Qhov no yog ua los ntawm txoj kev hnab cug zis los yog tej. Yog hais tias cov hlab yog nyob rau ntawm ib tug luv luv deb nyob rau hauv daim tawv nqaij, ces cov tshuaj mas txhaj mus rau hauv nws ntawm koob txhaj (tej).

Hnab cug zis yog siv rau ntxaum hlab ntsha, los leeg. Nyob rau hauv lub projection ntawm qhov kev kuaj txog ntsha ua rau lub zos tshuaj loog. Tom qab incision ntawm daim tawv nqaij thiab subcutaneous cov ntaub so ntswg fatty yog analyzed txog ntsha ntxiv thereto introducer (nyias yas raj txog 10 cm nyob rau hauv ntev). Los ntawm lub introducer lawv tsiv mus nyob rau lwm yam kev seev thiab lub catheter, yog li ntawd koj tsis ntawd puas cov phab ntsa hauv cov hlab ntsha. Los ntawm ib tug catheter nkag tau rau hauv tus zoo neeg sawv cev.

Tom qab cov tshuaj nkag mus rau hauv lub nkoj qab thus, nws kis tau los ntawm lub system. Ua ntej, cov hlab ntsha thiab cov leeg uas tau sau, ces arterioles, venules thiab cov hlab ntsha. Thaum lub sij hawm no, nrog rau cov kev pab los ntawm X-ray tshuab coj ib tug ob peb cov duab los yog yees duab luv luv.

Angiography hlab ntsha, los leeg (txoj kev tshawb no tau) yog muab sau tseg rau cov nrab uas tso cai rau koj mus qhia cov ntaub ntawv manipulation lwm tshwj xeeb.

Qhov twg thov li cas?

Soj ntsuam ntawm ib tug mob thiab leeg tshav permeability siv nyob rau hauv lub teb ntawm cov tshuaj, xws li:

• vascular phais - ua ntej phais tus kws kho mob qhia txog qhov chaw nyob thiab tus qauv ntawm cov ua chaw;
• Oncology - Primary teb chaw thiab metastases nais maum kuaj thaum lub sij hawm ntawm kev tsim kho ntawm lub capillary network;
• Pulmonology - mus soj ntsuam mob ntsws vasculature, raws li zoo raws li txiav txim qhov chaw ntawm lub pop-los ntshav;
• Phlebology - tshwj xeeb txiav txim seb lub hav zoov ntawm cov kev txwv, cov tsos ntawm aneurysms, ntshav txhaws, atherosclerosis, vascular kab mob, congenital anomalies ntawm qhov;
• neuroscience - lub paj hlwb hlab ntsha angiography qhia tau hais tias lub xub ntiag ntawm ib aneurysm, los ntshav, narrowing, mob dab.

Yog hais tias koj xav mus tshawb tag nrho cov hlab ntsha ntawm ib tug tej thaj chaw, ces txoj kev ua no yog hu ua ib tug general angiography. Nyob rau hauv cov ntaub ntawv ntawm kev ntsuag lub xeev ntawm ib tug neeg receptacles xws txoj kev tshawb no yog hu ua xim.

cerebral vascular angiography

Yuav kom daim ntawv ntsuam xyuas radiopaque yam khoom uas yog muab los ntawm ib tug catheter cov hlab ntsha xws li:

• txoj cai ncej puab;
• lub xub pwg;
• ulna;
• subclavian.

Lub catheter yog advanced los ntawm cov vascular system mus rau lub cheeb tsam nyob qhov twg lub xeem yog cov ceg txog ntsha. Nyob rau hauv lub lumen muab tshuaj. Tam sim ntawd ua rau ib tug series ntawm kev txhaj tshuaj los ntawm cov sab thiab pem hauv ntej ntawm lub taub hau. Yog hais tias nws yog tsim nyog los xyuas ntau nyob deb lug, ib tug thib ob feem ntawm muab tshuaj. Dua ua raws li los ntawm ib tug series ntawm cov duab nyob rau hauv yuav tsum tau projections. Lub zoo cuab tam yog muab tshem tawm thiab tus mob yog ua kom tiav.

cerebral angiography yuav tsum tau siv ntawm ib lub tuam loog kom loog qhov chaw nyob rau hauv uas lub hnab cug zis. Thaum lub catheter yog advanced los ntawm lub cev, tus neeg mob tsis txhob xav tias tsis xis nyob. Nrog rau cov kev taw qhia txog cov tshuaj tej zaum yuav tshwm sim nyob rau hauv lub qhov ncauj nws yog xim hlau saj, lub ntsej muag yaug kais dej, Thaum tshav kub kub nov ntawm nqaij tawv tu. Los ploj tom qab ib tug ob peb feeb.

Indications rau kev soj ntsuam ntawm lub hlwb hlab ntsha

Ib tug xov tooj ntawm pathological tej yam kev mob uas yuav tsum tau mob (MRI angiography yog ua rau ntxiv kom paub meej):

• aneurysm - expansion txog ntsha, uas yuav ua tau kom ntshav;
• Angioma - vascular mob;
• ischemic stroke - tus kws kho mob soj ntsuam qhov kev xav tau rau thrombolysis;
• hemorrhagic stroke - yog txiav txim los ntawm qhov uas hemorrhage;
• vascular malformation - ib tug kws kho mob soj ntsuam qhov kev theem ntawm cov kab mob thiab qhov chaw los ntshav;
• TBI - los mus txiav txim cov teebmeem ntawm tus poob plig;
• hematoma - cov kws muaj txuj kev kwv yees qhov chaw nyob thiab loj;
• mob - txhais tau tus loj, qhov chaw, lub xeev ntawm mov hlab ntsha.

Angiography hlab ntsha ntawm lub plawv

Coronary angiography - yog dab tsi? Qhov no txoj kev ntawm kev tshawb fawb cov hlab ntsha ntawm lub plawv. Hnab cug zis ntawm cov femoral los yog radial leeg catheter thiab nrhiav tau tus aorta. Radiopaque tshuaj muab qho nyob rau hauv txoj cai thiab sab laug coronary hlab ntsha. Ib tug series ntawm cov dluab yog ua li cas instantly.

Tus neeg mob tej zaum yuav tsis txaus siab ntawm cov tsos ntawm xws tsos mob li thawj coj ntawm cov tshuaj raws li:

• occlusive kab mob;
• thrombosis, thrombophlebitis;
• thromboembolism;
• kev raug mob, nrog los ntawm discontinuities hlab ntsha;
• dissecting aneurysm;
• kev luj xyuas ntawm cov hauj lwm zoo ntawm kev kho mob.

Kev npaj rau kev kuaj pom

Nco ntsoov qhia kom meej rau hauv lub qhaj ntawv ntawm ib tug neeg npau taws me ntsis rau iodine thiab nws cov derivatives. Yog hais tias tus neeg mob muaj ib tug cev xeeb tub, X-rays yog tsis siv. Nyob rau hauv cov ntaub ntawv no, nyiam MR angiography.

Ob lub lis piam cais dej cawv haus ib lub lim tiam - anticoagulants ( "heparin", "warfarin", "Tshuaj aspirin"). Ob peb hnub ua ntej tus mob yog nqa tawm ib tug xov tooj ntawm cov kev tshawb fawb xws li:

• Soj ntsuam ntshav thiab zis kev ntsuam xyuas, coagulation, biochemistry;
• ECG thiab ultrasound ntawm lub siab los;
• fluorography ntsws;
• ntshav hom thiab v tau;
• kev xeem rau kab mob (HIV, kab mob siab, syphilis).

Nyob rau lub tswv yim ntawm angiography yog nqa tawm nyob rau hauv ib tug qauv ntawm radiopaque substance. Cov hlab ntsha yog muab 0.1 ml. Nyob rau hauv cov ntaub ntawv ntawm urticaria, allergic rhinitis, conjunctivitis, arrhythmia siv yeeb tshuaj yog txwv tsis pub.

Nyob rau hauv lub yav tsaus ntuj ua ntej rau txoj kev yog nqa tawm ib tug cleansing enema, tu cov txheej txheem. Specialist assigns sedatives, uas tus neeg mob so kom txaus. Nyob rau thaum sawv ntxov ntawm examinee yuav tsum tsis txhob noj mov los yog haus dej haus nyob rau hauv pem hauv ntej ntawm manipulation xav mus nchuav tag lub zais zis.

nuances kev kawm

Muaj ib tug xov tooj ntawm pathological tej yam kev mob uas yuav tsum tau ib tug ntev thiab ceev faj mus kom ze rau qhov kev npaj ntawm xws li ib tug txheej txheem yog angiography. Yuav ua li cas yog tus neeg mob yuav tsum tau ua li cas rau tus mob yog uneventful?

Ntshav siab, nws yog tsim nyog los tswj. Rau lub hom phiaj no siv "Nifedipine", "Dibazol" "Raunatin" los yog lwm yam antihypertensive tshuaj uas tus neeg mob yog nyob rau hauv qhov kev kho mob.

Nyob rau hauv lub xub ntiag ntawm mob arrhythmias muab "Panangin" los yog poov tshuaj tshuaj dawb. Ntawv sau yuav tshuaj los ntawm ib tug kws kho mob siv mob glycosides. Nyob rau hauv CHD los yog lub plawv mob syndrome siv "nitroglycerin" "Ernits" "Sustak".

raum tus kab mob kab mob yuav tsum tau dej saturation. Pab radiopaque tshuaj yuav tsis tshua ua raws li ib tug irritant neeg saib xyuas thiab yog sai tas nyob hauv cov zis.

Yog hais tias koj muaj ib tug mob los ntawm cov kab mob (sinusitis, ntsws), cov kws prescribes tshuaj tua kab mob los yog sulfonamides ntawm 2 lub lis piam ua ntej rau txoj kev tshawb.

Contraindications rau angiography

Lub diagnostic txoj kev yog tsis nqa tawm thaum muaj ib tug kev hem thawj rau cov xwm txheej thiab noj qab haus huv ntawm tus neeg mob. Qhov no tshwm sim nyob rau hauv tej yam kev mob xws li:

• mob inflammatory kab mob;
• puas siab puas ntsws;
• raum tsis ua hauj lwm;
