Cerebral angiography

Cerebral angiography yog txheej txheem uas siv cov xim tshwj xeeb (cov khoom sib piv) thiab duab xoo hluav taws xob kom pom cov ntshav ntws mus rau lub hlwb li cas.

Cerebral angiography tiav hauv tsev kho mob lossis chaw hluav taws xob.

• Koj pw ntawm ib lub rooj ua yees duab.
• Koj lub taub hau tau tuav tseem siv pluaj, ntaub nplaum lossis ntaub pua av, yog li koj TSIS TXHOB txav nws thaum lub sijhawm ua haujlwm.
• Ua ntej pib qhov kev sim, koj tau muab cov tshuaj loog me me los pab koj so kom txaus.
• Ib qho electrocardiogram (ECG) tswj xyuas koj lub siab thaum ua kev kuaj. Cov ntawv nplaum ib qho, hu ua cov tawv nqaij, yuav muab tso rau ntawm koj txhais tes thiab ceg. Cov xov hlau sib txuas ua rau lub tshuab ECG.

Ib thaj chaw ntawm koj lub cev, feem ntau ua puab tais, yog ntxuav thiab loog nrog lub zos loog tshuaj (tshuaj loog). Ib txoj hlab nyias nyias, hu ua lub raj xa dej yog tso rau ntawm cov leeg ntshav. Txoj raj yas txuas yog maj mam txav los ntawm cov hlab ntshav loj hauv plab thiab hauv siab mus rau hauv cov leeg leeg hauv caj dab. Kev xoo hluav taws xob pab tus kws kho mob coj tus ntsuas catheter rau txoj hauj lwm kom yog.

Thaum cov catheter tso rau hauv qhov chaw, lub zas xim yuav xa los ntawm lub raj xa dej. Cov duab xoo hluav taws xob tau siv los saib seb cov xim txav txav los ntawm cov leeg thiab cov hlab ntshav ntawm lub hlwb. Cov xim tuaj yeem pab ua kom muaj kev cuam tshuam twg hauv cov ntshav khiav.

Qee zaum, khoos phis tawm tshem cov pob txha thiab cov nqaij ntawm cov duab uas tau pom, kom tsuas yog cov hlab ntsha uas muaj cov zas xim pom. Qhov no hu ua digital rho cov duab xis sab xis (DSA).

Tom qab xoo hluav taws xob xoo, ntsuas lub raj yas tawm. Kev thov siab rau ntawm txhais ceg ntawm qhov chaw ntxig rau 10 mus rau 15 feeb kom cheem los ntshav lossis siv khoom los siv kaw lub qhov me me. Ib txoj siv tawv nruj yog tom qab thov. Koj txhais ceg yuav tsum ua ncaj rau li 2 txog 6 teev tom qab kev ua haujlwm. Saib thaj tsam ntawd los ntshav tsawg kawg 12 teev tom ntej. Muaj qee zaus, mob pob tes leeg yog siv hloov ntawm cov leeg puab leeg.

Angiography nrog cov raj yas siv tau tsawg dua tam sim no. Qhov no yog vim MRA (sib nqus resonance angiography) thiab CT angiography muab cov duab pom tseeb dua.

Ua ntej ntawm txoj kev, koj tus kws kho mob yuav kuaj koj thiab kuaj ntshav.

Qhia tus kws kho mob yog koj:

• Muaj keeb kwm ntawm teeb meem los ntshav lossis siv cov tshuaj uas yog ntshav dua
• Tau ua xua tsis haum rau xoo hluav taws xob xoo xim lossis lwm yam tshuaj iodine
• Tej zaum cev xeeb tub
• Muaj teeb meem lub raum kev ua haujlwm

Luag yuav kom koj tsis txhob noj lossis haus ib yam dabtsi rau 4 rau 8 teev uantej txoj kev kuaj xyuas.

Thaum koj tuaj txog ntawm qhov chaw kuaj sim, koj yuav tau hnav khaub ncaws hnav hauv tsev kho mob. Koj yuav tsum tshem tag nrho cov hniav nyiaj hniav kub.

Lub rooj xoo hluav taws xob yuav hnov ​​mob thiab txias txias. Koj tuaj yeem thov kom pam vov lossis tog hauv ncoo.

Qee tus neeg hnov ​​mob qog thaum muab tshuaj loog (pleev tshuaj loog). Koj yuav hnov ​​ib nyuag, qhov mob thiab lub siab thaum lub raj xa mus rau hauv lub cev. Thaum thawj zaug tso thawj zaug, koj yuav tsis hnov ​​qhov catheter lawm.

Qhov tsis sib thooj yuav ua rau sov lossis kub siab ntawm daim tawv nqaij ntawm lub ntsej muag lossis taub hau. Qhov no ib txwm ua thiab feem ntau yuav ploj mus li ntawm ob peb feeb.

Tej zaum koj yuav muaj qhov sib tw me thiab ua pob rau ntawm qhov chaw ntawm kev txhaj tshuaj tom qab kuaj.

Cerebral angiography feem ntau siv los txheeb xyuas lossis paub qhov teeb meem nrog cov hlab ntshav hauv lub hlwb.

Koj tus kws kho mob yuav xaj kom kuaj mob no yog tias koj muaj cov tsos mob lossis cov cim ntawm:

• Cov hlab ntsha hauv ntshav tsis zoo hauv lub hlwb (vauv tsis zoo)
• Bulging cov hlab ntsha hauv lub hlwb (aneurysm)
• Nqaim ntawm cov hlab ntsha hauv lub hlwb
• Kev o ntawm cov hlab ntshav hauv lub hlwb (vasculitis)

Nws qee zaum siv rau:

• Saib ntshav ntws mus rau lub qog.
• Txheeb xyuas cov hlab ntsha ntawm lub taub hau thiab caj dab ua ntej kev phais mob.
• Nrhiav ris tsho uas tej zaum ua rau mob stroke.

Qee qhov xwm txheej, tus txheej txheem no yuav raug siv kom tau txais cov ncauj lus kom ntxaws tom qab qee yam txawv txav tau kuaj los ntawm MRI lossis CT scan ntawm lub taub hau.

Kev kuaj ntshav no tseem tuaj yeem npaj tau rau hauv kev kho mob (cov txheej txheem tiv thaiv hluav taws xob) los ntawm qee cov ntshav ntsha.

Qhov zas xim uas ntws tawm ntawm cov hlab ntshav tuaj yeem yog cov cim qhia tias los ntshav.

Cov hlab ntsha nqaim los yog txhaws tej zaum yuav qhia:

• Cov roj ntsha tso nyiaj
• Spasm ntawm lub paj hlwb cov leeg
• Inherited mob
• Cov ntshav txhaws ua rau mob stroke

Qhov tawm ntawm cov ntshav cov ntshav tuaj yeem yog vim:

• Lub hlwb hlav
• Los ntshav hauv lub pob txha taub hau
• Aneurysm
• Kev sib txuas tsis zoo ntawm cov hlab ntsha thiab cov leeg ntshav ntawm lub hlwb (arteriovenous malformation)

Cov txiaj ntsig tsis zoo kuj yog los ntawm mob qog nqaij hlav uas pib nyob rau lwm qhov ntawm lub cev thiab tau kis mus rau lub hlwb (metastatic hlav hlav).

Teeb meem yuav suav nrog:

• Kev tsis haum cov tshuaj pleev rau cov xim sib txawv
• Tso ntshav txhaws lossis ntshav uas cov tso raj txuas rau, uas tuaj yeem thaiv cov ntshav ntws mus rau ceg lossis tes (tsawg)
• Kev puas tsuaj rau cov leeg ntshav lossis leeg phab ntsa los ntawm txoj raj, uas tuaj yeem thaiv cov ntshav kev thiab ua rau mob stroke (tsis tshua muaj)
• Kev puas tsuaj rau lub raum los ntawm qhov sib txawv ntawm IV

Qhia koj tus kws kho mob sai li sai tau yog tias koj muaj:

• Tsis muaj zog ntawm koj cov leeg ntsej muag
• Loog ntawm koj txhais ceg thaum lossis tom qab cov txheej txheem
• Hais lus tsis meej thaum lub sijhawm lossis tom qab txheej txheem
• Cov teeb meem tsis pom kev zoo lub sijhawm lossis tom qab cov txheej txheem
