Isuzuma riheruka rireba imiyoboro y'amaraso mu bwonko (Transcranial Doppler) - ese ni ikintu cyo gutinya?

Ni ibisanzwe kumva ufite ubwoba no guhangayika gato iyo muganga wawe akubwiye gukora isuzuma ry’ubwonko. Ushobora gutekereza uti "Ni iki cyabaye?" Ariko iyi isuzuma, yitwa transcranial Doppler, nta cyo ugomba gutinya. Mu magambo make, ni ikizamini cyizewe cyane, kimwe n’isuzuma rya ultrasound rikorerwa umubyeyi utwite kugira ngo arebe umwana we.

Mu magambo make, Transcranial Doppler ni iki?

Ubu ni uburyo bukoresha imiraba y'amajwi kugira ngo bugenzure uko amaraso atembera mu mitsi y'amaraso mu bwonko bwawe. Kimwe no kugenzura niba hari imodoka nyinshi mu muhanda, niba imodoka zigenda buhoro, cyangwa niba zigenda buhoro, ubu buryo bwo gusuzuma butuma muganga areba uko amaraso agenda mu mitsi y'amaraso mu bwonko bwawe.

Ibi bikoreshwa mu gusuzuma indwara z'imitsi yo mu bwonko no gukurikirana ibisubizo by'ubuvuzi bumwe na bumwe.

Kuki muganga yagira inama yo gusuzuma iki gipimo?

Tekereza umuntu ahora arwaye isereri, adashobora kuvuga mu buryo butunguranye, cyangwa afite ibimenyetso nko kugira ibinya mu maguru. Mu bihe nk'ibi, muganga ashobora gukeka ko hari ikibazo mu mitegurire y'amaraso mu bwonko. Icyo gihe ni bwo iyi scan iba ingenzi cyane.

Reba imbonerahamwe iri hepfo kugira ngo umenye indwara nyamukuru iki kizamini gishobora gufasha mu gusuzuma.

Iyi scan ikora ite?

Ibibera hano biroroshye cyane. Igikoresho cyo gupima amajwi cyohereza amajwi mu ngirabuzimafatizo z'agahanga kawe. Aya majwi akubita imitsi y'amaraso iri mu bwonko, agakubita uturemangingo tw'amaraso twihuta tubamo, hanyuma akagaruka nk'amajwi. Muganga akoresha ecran ya mudasobwa kugira ngo arebe umuvuduko n'icyerekezo cy'amajwi agaruka kugira ngo afate umwanzuro ku bijyanye n'uko amaraso atembera mu bwonko.

Ese ngomba kwitegura mbere yo gupimwa?

Ariko, niba wambaye indorerwamo z'amaso (contact lenses), ushobora gusabwa kuzikuraho mbere yo gupimwa. Nanone, niba wambaye igitambaro cyo mu mutwe, umutekinisiye ugukorera ikizamini azaganira nawe uburyo bwo kuzikuraho by'agateganyo cyangwa kuzihindura. Uzahabwa ubuzima bwite ukeneye kugira ngo ubikore.

Ni iki kibaho mu gihe cyo gupima?

Uburyo bwo gukora iki kizamini bworoshye cyane.

• Ubwa mbere, uzategekwa kuryama ku gitanda cyo gupimisha cyangwa kwicara ku ntebe.
• Hanyuma, umutekinisiye azashyira gel ikozwe mu mazi ku ruhu rwawe, mu bice bigomba gusuzumwa. Iyi gel ikunze gusigwa inyuma cyangwa imbere y'ijosi ryawe, hejuru y'amagufwa y'uruhago rwawe, imbere y'ugutwi kwawe, cyangwa hejuru y'ijisho ryawe. Ibi biterwa nuko aha ariho imiyoboro y'amaraso ijyana amaraso mu bwonko bwawe iherereye.Iyi gel ntabwo yangiza uruhu kandi ntihumanya imyenda.
• Hanyuma, agakoresho gato kameze nk'ikaramu (kitwa transducer ) karajyanwa hejuru y'agakoresho. Aka gakoresho kohereza amajwi mu bwonko kagafata amajwi agaruka.
• Muri iki gihe, amaraso y'ubwonko bwawe agaragara kuri ecran ya mudasobwa, haba mu mashusho cyangwa mu mashusho y'amabara.
• Igikuru ni uko utagomba kunyeganyeza umutwe cyangwa kuvuga muri iki kizamini.
• Iyo ikizamini kirangiye, gel yakoreshejwe irahanagurwa.

Hari igihe umurongo wa IV ushobora gushyirwa mu mutsi uri mu kuboko kwawe hanyuma ugaterwamo saline. Ibi bikorwa kugira ngo harebwe ko hari umwobo mu mutima wawe ushobora gutuma amaraso agwa mu bwonko.

Ibi birababaza? Bizatwara igihe kingana iki?

Nta bubabare na gato. Nta kubabara cyangwa ububabare bihari. Ushobora kumva urimo gukonja gato iyo ukoze gel. Uzumva urimo gukandagira gato iyo wimuye igikoresho (transducer) ku ruhu rwawe, ni byo gusa.

Ubu buryo bwo gupima busanzwe bumara hagati y'iminota 30 na 60 , bitewe n'ubwoko bw'ikizamini wahawe.

Ni iki kigenda nyuma y'ikizamini? Reka twige ku bisubizo.

Iyo ikizamini kirangiye, ushobora gutaha uwo munsi. Kubera ko ibi ntacyo byangiza ku mubiri, nta kibazo kiri mu gutwara imodoka cyangwa gukora imirimo yawe isanzwe.

Ku bijyanye n'ibisubizo, bishobora kuboneka nyuma gato y'ikizamini. Muganga wawe ashobora kuganira nawe ku bisubizo kuri uwo munsi. Cyangwa ashobora guteganya undi munsi wo kubisuzuma.

Hashobora kubaho ubwoko bubiri bw'ibisubizo:

• Ibisubizo bisanzwe: Ibi bivuze ko nta kibazo cy'amaraso anyura mu bwonko bwawe, kandi byose bigenda neza.
• Ibisubizo bidasanzwe: Ibi bivuze ko umutsi w'amaraso utanga amaraso mu bwonko ushobora kuziba, gufungana, cyangwa kuziba mu bundi buryo. Ibi bishobora kugaragaza ikintu nk'amaraso apfundikiye ava mu mutima (embolism) cyangwa umwobo mu mutima (PFO).

Niba ubonye igisubizo kidasanzwe, ntugatinye. Bivuze ko muganga wawe ashobora gusuzuma indwara yawe no gutangira ubuvuzi bukwiye. Ashobora kandi gutegeka ikindi kizamini kugira ngo amenye byinshi.
