Ikozvino imwe yenzira dzakabudirira uye dzakakwirira-inyanzvi yekuongororwa inoshandiswa muzvirwere zvevascular isiography yemakemikari midziyo. Rudzi urwu runokubvumira kufungidzira zvese nhengo dzevanhu nemidziyo yehukuru chero upi zvake, saka chiremba anogona kugumisa pamusoro pekuvapo kweanerysm, kuvhara uye matumbo. Mukuwedzera, kazhinji angiography inoshandiswa kugadzirira kuvhiyiwa.
Zviratidzo zvekunyora
Iyi nzira inodiwa mumamiriro ezvinhu akadaro:
- hukama hurefu kwenguva refu, iyo nzira dzetsika dzisingakwanisi kubata nadzo;
- kunzwa kusanzwisisiki munharaunda yemudzinza;
- chizunguzi, chisingafananidzi nekushanduka kwomuviri wemuviri;
- kushungurudzika, kusina kukonzerwa nokudya;
- frequency syncope ;
- congenital heart disease;
- kukanganisa kweropa kupararira mumamota.
Emergency angiography yakatemerwa:
- intraoperative diagnostics;
- nhengo ischemia;
- zvipembenene nekukuvara kwemidziyo yeropa;
- mukana wekudzokazve kana kubatana kwakapfurikidza.
MRI angiography yemidziyo yemagetsi
Izvi zvinosanganisira kushandisa magnetic tomograph, inokubvumira kuwana mufananidzo wakaisvonaka. MR angiography inoshandiswa kune aneurysms yemakemikari emidziyo, kusimbisa kuvapo kwe stenosis uye occlusions. Iyi nzira inzira yakachengeteka yekuwana ruzivo pamusoro pemamiriro ezvinhu emidziyo, kushanda kwavo uye nzira dzinoitika mazviri. Cerebral angiography inokubvumira kubvisa chidimbu chekusiyanisa kuumbwa kuwana ruzivo pamusoro pemidziyo yeuropi. Zvisinei, kana zvakakosha kuongorora zvirwere, zvino kusiyana kunoshandiswa. Mugumisiro wekutsvaga mufananidzo wemidziyo ine zvakanyatsorongwa.
CT angiography yemidziyo yemakumbo
Iyi nzira inoshandiswawo kuitisa chidzidzo chemamiriro emamiriro ezvinhu europi. Mukati yeongororo, mifananidzo mitatu-miviri inowanikwa, iyo inoita kuti zvive nyore kuumba mifananidzo yeangiographic uye kuongorora nhengo panzvimbo yakakodzera. Nekombiyuta nzira yekuongorora, kuwana ruzivo pamusoro pemidziyo yeuropi inopfuura achishandisa chinhu chakasiyana-siyana che-iodine, iyo, kana ichipfuura nhengo dzenhengo, inokubvumira kuti uwane mifananidzo yakanyatsotsanangurwa panguva yekunyorwa. Kubatsira kwe MSCT (multi-helical computer angiography) ndiko kukwanisa kudzidza chiropi muhupi nemamita anenge 1 mm uye kuwana chifananidzo chayo chero ipi zvayo mumagadzirirwo asingakwanisi kugadziriswa nenzira dzakasarudzika, dzakadai secanio-caudal.
Kuongororwa kwakaitwa seizvi:
- Pamberi pemitambo yacho inotanga, maviri milliliters eparanisi inorohwa mukati-kati kuti ione kuti muviri unoita sei.
- Sezvo uine chokwadi mukusavapo kwemazuva ose , pinda zvinhu mumhino yepamberi kana brashi.
- Chiremba anoona musiyano wemidziyo kwekanguva, zvino anotora mifananidzo.
- Mushure mokushandura zvifananidzo mumapurogiramu chaiwo, fungidzira kuti midziyo yakasiyana-siyana.
Contraindications kune angiography yemakemikari midziyo
Sezvo nzira iyi inogona kukanganisa mamwe matambudziko, mapoka evanhu anotevera anoregererwa kuita izvi:
- kusagadzikana zvikamu zve iodine-ine inopesana (munyaya iyi gadolinium makundi anopiwa);
- mumutambo wakaoma wekurwara mupfungwa;
- ane zvirwere zvisingaperi zvezviviri zvemukati;
- mumutambo wakaoma wemyocardial infarction;
- kutambura kubva mukukundikana kwetsotsi, nekuda kwekuti hazvibviri kubvisa kusiyana kwemuviri;
- kana pane zvinetso neropa coagulability;
- vakadzi vane pamuviri.
