I-echocardiogram ye-transchoopdigram (TEE) uvavanyo olusetyenziswa ukuhlola isakhiwo kunye nomsebenzi wentliziyo yakho. Njenge- echocardiogram eqhelekileyo , i-TEE isebenzisa amaza omsindo ophezulu ukuvelisa ixesha langempela, ukuhamba komfanekiso wentliziyo yokubetha. Nangona kunjalo, ngelixa i-echocardiography ephambili iyenziwa ngokubeka i-wave transducer kwindonga yakho yesifuba, kunye ne-TEE i-transducer idluliselwa kwisipopu (ityhubhu yakho yokugwinya).
I-TEE inokuvelisa imifanekiso ecacileyo yomzimba, kwaye ukusebenzisa i-TEE esikhundleni se-echocardiogram efanelekileyo inokuba luncedo kakhulu phantsi kweemeko ezifanelekileyo.
I-TEE eyenziwe njani?
Ukuba unayo i-TEE uza kuqala unikezwe ngokukrakra, kwaye i-gag reflex yakho iya kugxothwa ngokutshiza i-anesthetic yendawo yangasemva emqaleni wakho. I-transducer ye-echo iya kuthi idluliselwe emlonyeni nasemqaleni, kwaye iphantsi kwe-oophagus yakho de ibe ibeke ngqo emva kwentliziyo yakho.
Xa usesesikhundleni, i-transducer isetyenziselwa ukuhlawulela amagagasi omsindo entliziyweni yakho, njengokuba kunjalo kwi-echocardiogram. Amaza omsindo abuyelayo aqhutyelwa umfanekiso ohambelayo wentliziyo yakho kwaye uqikelelwe kwikhompyutheni yekhompyuter ukuhlalutya.
Inzuzo
Inzuzo yangempela ye-TEE kukuba iyakwazi ukuvelisa imifanekiso enemifanekiso enzulu ngakumbi kune-echocardiogram eqhelekileyo. Oku kungenxa yokuba umfanekiso we-echo wenziwe ngokusuka emva kwentliziyo - amaza omsindo akudingeki angene ngaphakathi kwembambo yentambo kunye neengxube zamaphaphu ngaphambi kokufikelela entliziyweni.
Kufuneka nini i-TEE efanelekileyo?
Kukho imeko zintathu apho i-TEE inganconywa ngaphezu kwe-echocardiogram epheleleyo.
Okokuqala, i-TEE iyakunceda nayiphi na imifanekiso eko efanelekileyo ayifumaneki ngeteknoloji ze-echo eziqhelekileyo. Oku kungenzeka kubantu abaneendonga zesifuba ezinzima kakhulu, okanye ababenomfesane, okanye i-traum tract or recent surgery.
Ngamanye amaxesha kunzima ukuyifumana umfanekiso ocacileyo kunye ne-echo epheleleyo ngenxa yesizathu esicacileyo. Nge-TEE, imifanekiso emihle ye-echo ifumaneka malunga nabani na.
Okwesibini, i-TEE inokwenziwa kwigumbi lokusebenza ngexesha lokuvulwa kwentliziyo evulekile. I-TEE intraoperative iyanceda ngokukhethekileyo ekusebenziseni i-valve inhliziyo, ingakumbi xa wenza ukulungiswa kwe-valve ukuphatha ukubuyiswa kwe-mitral . I-TEE inokunika impendulo ngokukhawuleza kumgqithisi ogqirha njengoko kulungiswa.
Okwesithathu, i-TEE inokubaluleka kakhulu ekuhloleni ukuba isigulane siphuhlisa i-blood clots kwi-atrium yekhohlo. Ngokomzekelo, ukubonakalisa nge-TEE ukuba akukho maqhepha egazi akhoyo apha angenza ukuba i- cardioversion ye-fibrillation ye-atrial ikhuseleke kakhulu.
Iingxaki
Ingxaki eqhelekileyo kwi-TEE yintsikelelo ethile yokunyakaza nokuphunga komqala ngexesha le nkqubo. Nangona kunjalo, ngokuqhelekileyo kulula ukulawula le mpawu nge-sedation kunye ne-numbing yomqala. Unokuba nesifo somqala kwimini embalwa emva kwenkqubo. Ngokuqhelekileyo, i-perforation ye-oophagus iyakwenzeka, yinto engxamisekileyo yokuphaphazelekayo, kwaye ngokukhawuleza kuphuma igazi kwi-esophagus ibonakala. Nangona kunjalo, ezi ziganeko ezimbi kakhulu aziqhelekanga, kwaye i-TEE ithathwa njengekhuselekile.
