Manje enye yezindlela zokuhlola eziphumelela kakhulu futhi eziphakeme kakhulu ezisebenzisayo ezifweni zezinthambo i-angiography yemikhumbi ye-cerebral. Lolu hlobo lukuvumela ukuba uzibone ngeso lengqondo zonke izitho zomuntu nezitsha kwanoma yisiphi isayizi, ngakho udokotela angenza isiphetho mayelana nokuba khona kwe-aneurysm, ukuvinjelwa nama-tumor. Ngaphezu kwalokho, ngokuvamile i-angiography isetshenziselwa ukulungiselela ukuhlinzwa.
Izinkomba ze-angiography
Le nqubo iyadingeka ezimweni ezinjalo:
- i-headache ehlala isikhathi eside, yiziphi izindlela zendabuko ezingakwazi ukubhekana nazo;
- ukungazizwa kahle esifundeni somlomo wesibeletho;
- ukuzondwa, okungahambisani nokushintsha kwesimo somzimba;
- isicanucanu, esingabangelwa ukudla;
- i- syncope evamile;
- isifo senhliziyo esiswini;
- ukwephulwa kwegazi ngegazi.
I-angiography ephuthumayo ishiwo:
- ukuxilongwa kwe-intraoperative;
- isitho ischemia;
- izilonda nokulimala kwemithambo yegazi;
- amathuba okuphindaphinda noma ukuphindaphindiwe okuphindaphindiwe.
I-MRI engiography yemikhumbi ye-cerebral
Le nqubo ihilela ukusebenzisa i-tomograph yamagnetic, okuvumela ukuba uthole isithombe esihle kakhulu. I-MR angiography isetshenziselwa ama-aneurysms wemishini ye-cerebral, ukuqinisekisa ukuthi kukhona khona isifo se-stenosis nesimangalo. Le ndlela yindlela ephephile kakhulu yokuthola ulwazi mayelana nezici zezimpahla, ukusebenza kwazo nezinqubo ezenzeka kuzo. I-angiography ye-Cerebral ikuvumela ukuba uqede isidingo sokuqhathaniswa okuhlukile ukuze uthole ulwazi mayelana nemikhumbi yobuchopho. Kodwa-ke, uma kudingekile ukuphenya izicubu, bese kuqhathaniswa. Umphumela wocwaningo luyisithombe sezitsha kanye nokuhlelwa kwawo okuningiliziwe.
I-CT engiography yemikhumbi ye-cerebral
Le ndlela isetshenziselwa ukuqhuba isifundo sombuso wemikhumbi yobuchopho. Esikhathini socwaningo, kutholakala izithombe ezintathu, okwenza kube lula ukudala izithombe ze-angiographic nokutadisha izitho ezingeni elidingekayo. Ngendlela yekhompiyutha ye-angiography, ukuthola ulwazi mayelana nezitsha zobuchopho kudlula usebenzisa into ehlukile e-iodine equkethe i-iodine, okuthi, lapho udlula ezithombeni, ikuvumela ukuba uthole izithombe ezinemininingwane eningi ngesikhathi sokuskena. Inzuzo ye-MSCT (i-computer-helical computer angiography) ikhono lokutadisha isitsha sobuchopho ngobubanzi obufinyelela ku-1 mm futhi sithole isithombe sayo kunoma yikuphi ukubonakala okungafinyeleleki ezindleleni ezijwayelekile, njenge-cranio-caudal.
Ukuhlolwa kanje:
- Ngaphambi kokuba inqubo iqale, ama-milliliters amabili okuphambene ajojowe ngaphakathi ngaphakathi ukuze ahlole ukuphendula komzimba.
- Njengoba uqinisekile ukuthi ungabikho kokungezwani komzimba , faka into emgodini we-forearm noma ibhulashi.
- Udokotela ubuka umehluko wezitsha okwesikhashana, bese uthatha izithombe.
- Emva kokucubungula izithombe ezinhlelo ezikhethekile, ngeso lengqondo lezi zitsha zihlolwe ngokuhlukile.
Ukuqhathaniswa kwe-angiography yemikhumbi ye-cerebral
Njengoba inqubo ingabangela ezinye izinkinga, amaqembu alandelayo abantu avunyelwe ukwenza lokhu kuhlolwa:
- ukuba nengxenye yokubekezelelana kokuqhathaniswa kwe-iodine (kulokhu kuhlanganiswa i-gadolinium compounds);
- esimweni esibucayi sokugula kwengqondo;
- nezifo ezingapheli zezitho zangaphakathi;
- esiteji esibucayi se-infarction ye-myocardial;
- ukuhluleka ukuhluleka kwenkunzi, ngenxa yokuthi akunakwenzeka ukususa umehluko emzimbeni;
- uma kunezinkinga ngegazi coagulability;
- abesifazane abakhulelwe.
