I-angiography yeCerebral

I-Cerebral angiography yinkqubo esebenzisa idayi ekhethekileyo (izinto ezahlukileyo) kunye ne-x-reyi ukubona ukuba igazi lihamba njani ngengqondo.

I-angiography yeCerebral yenziwa esibhedlele okanye kwiziko le-radiology.

• Ulele kwitafile ye-x-ray.
• Intloko yakho igcinwe isebenzise umtya, iteyiphu, okanye iisanti zeebhegi, ke AKUKHO uyihambisayo ngexesha lenkqubo.
• Phambi kokuba uvavanyo luqale, unikwa umthomalalisi ukuze akhulule.
• I-electrocardiogram (ECG) ibeka esweni umsebenzi wentliziyo yakho ngexesha lovavanyo. Izinti ezincangathi, ezibizwa ngokuba zezizikhokelo, ziya kubekwa ezingalweni nasemilenzeni. Iingcingo zidibanisa izikhokelo kumatshini we-ECG.

Indawo yomzimba wakho, ihlala i-groin, iyacocwa kwaye ibonakaliswe ngeyeza lendawo (iyeza). Ityhubhu ebhityileyo engenanto ebizwa ngokuba yi-catheter ibekwa ngomthambo. I-catheter ishukunyiswa ngononophelo kwimithambo yegazi engundoqo kwindawo yesisu nasesifubeni iye emthanjeni entanyeni. IX-reyi inceda ugqirha akhokelele i-catheter kwindawo efanelekileyo.

Nje ukuba i-catheter ikho, idayi ithunyelwa nge-catheter. Imifanekiso ye-X-ray ithathwa ukuze ibone indlela idayi ehamba ngayo kwimithambo yegazi kunye nemithambo yegazi yengqondo. Idayi inceda ukuqaqambisa naziphi na iibhloksi ekuhambeni kwegazi.

Ngamanye amaxesha, ikhompyuter isusa amathambo kunye nezicubu kwimifanekiso ebonwayo, ukuze kubonakale kuphela imithambo yegazi ezele yile dayi. Oku kubizwa ngokuba yi-digital subtraction angiography (DSA).

Emva kokuba i-x-ray ithathiwe, i-catheter iyarhoxiswa. Uxinzelelo lusetyenziswa emlenzeni kwindawo ekufakwe kuyo imizuzu eli-10 ukuya kweli-15 ukunqanda ukopha okanye isixhobo sisetyenziselwa ukuvala umngxunya omncinci. I-bandage eqinileyo iyasetyenziswa. Umlenze wakho kufuneka ugcinwe ngokuthe ngqo kwiiyure ezi-2 ukuya kwezi-6 emva kwenkqubo. Jonga indawo yokuphuma kwegazi okungenani iiyure ezili-12 ezizayo. Kwiimeko ezinqabileyo, kusetyenziswa umthambo wesihlahla endaweni yomthambo we-groin.

I-Angiography ene-catheter isetyenziswa ngokufuthi ngoku. Kungenxa yokuba i-MRA (magnetic resonance angiography) kunye ne-CT angiography inika imifanekiso ecacileyo.

Ngaphambi kwenkqubo, umboneleli wakho uya kukuvavanya kwaye a-odole uvavanyo lwegazi.

Xelela umboneleli ukuba:

• Unembali yeengxaki zokopha okanye uthathe amayeza anciphise igazi
• Uye waba neempendulo ezichaseneyo nedayi yokuthelekisa ye-x-ray okanye nayiphi na into ye-iodine
• Ngamana unokukhulelwa
• Yiba neengxaki zomsebenzi wezintso

Unokuxelelwa ukuba ungatyi okanye usele nantoni na iiyure ezi-4 ukuya kwezi-8 phambi kovavanyo.

Xa ufika kwindawo yovavanyo, uya kunikwa ingubo yasesibhedlele ukuba uyinxibe. Kufuneka ususe bonke ubucwebe.

Itafile ye-x-ray inokuziva kunzima kwaye ibanda. Unokucela ingubo okanye umqamelo.

Abanye abantu baziva bebuhlungu xa kunikwa iyeza lokuthamba (iyeza). Uya kuziva iintlungu ezimfutshane, ezibukhali kunye noxinzelelo njengoko i-catheter isiwa emzimbeni. Nje ukuba ukufakwa kokuqala kugqityiwe, awuyi kuva catheter kwakhona.

Umahluko unokubangela imvakalelo efudumeleyo okanye evuthayo yolusu lobuso okanye lwentloko. Oku kuqhelekile kwaye kuhlala kuhamba kwimizuzwana embalwa.

Unokuba nokuthantamisa okuncinci kunye nokugruzuka kwindawo yenaliti emva kovavanyo.

I-angiography yeCerebral ihlala isetyenziselwa ukuchonga okanye ukuqinisekisa iingxaki kwimithambo yegazi esengqondweni.

Umboneleli wakho unokuyalela olu vavanyo ukuba uneempawu okanye iimpawu ze:

• Imithambo yegazi engaqhelekanga kwingqondo (i-vascular malformation)
• Ukuhambisa isitya segazi kwingqondo (aneurysm)
• Ukunciphisa imithambo kwingqondo
• Ukudumba kwemithambo yegazi kwingqondo (vasculitis)

Ngamanye amaxesha isetyenziselwa:

• Jonga ukuhamba kwegazi kwithumba.
• Vavanya imithambo yentloko nentamo ngaphambi kotyando.
• Fumana ihlwili elinokubangela ukubetha.

Ngamanye amaxesha, le nkqubo inokusetyenziselwa ukufumana ulwazi oluthe kratya emva kokuba kufunyenwe into engaqhelekanga yi-MRI okanye i-CT scan entloko.

Olu vavanyo lunokwenziwa nokulungiselela unyango (iinkqubo ze-radiology zongenelelo) ngendlela yemithambo ethile yegazi.

Umahluko wokwahluka kwedayi ephuma emthanjeni wegazi unokuba luphawu lokopha.

Imithambo emxinwa okanye evaliweyo inokucebisa:

• Iidiphozithi zeCholesterol
• Ispasm somthambo wobuchopho
• Ukuphazamiseka okwazuzwa njengelifa
• Amahlwili egazi abangela ukubetha

Ngaphandle kwendawo yegazi inokubangelwa:

• Amathumba ebongo
• Ukopha ngaphakathi kokhakhayi
• Unyango
• Unxibelelwano olungaqhelekanga phakathi kwemithambo kunye nemithambo kwingqondo (i-arteriovenous malformation)

Iziphumo ezingaqhelekanga zisenokubangelwa ngumhlaza oqale kwelinye icala lomzimba kwaye uye wanwenwela kwingqondo (metastatic brain tumor).

Iingxaki zinokubandakanya:

• Ukusabela okungahambelaniyo nedayi eyahlukileyo
• Igazi eligazi okanye ukopha apho kufakwa khona i-catheter, enokuthintela ukuhamba kwegazi emlenzeni okanye esandleni (kunqabile)
• Ukonakala kumthambo okanye udonga lweartery olusuka kwi-catheter, olunokuthi lubambe ukuhamba kwegazi kwaye lubangele ukubetha (kunqabile)
• Umonakalo kwizintso ezivela kwi-IV Umahluko

Xelela umboneleli wakho ngoko nangoko ukuba unayo:

• Ubuthathaka kwimisipha yakho yobuso
• Ubudenge emlenzeni wakho ngexesha okanye emva kwenkqubo
• Intetho egudileyo ngexesha okanye emva kwenkqubo
• Iingxaki zombono ngexesha okanye emva kwenkqubo
