Iintliziyo Zentliziyo Zisetyenziselwa Ukujongana Neengxaki Ezininzi Zeentliziyo
I-catheterization ye-cardiac kunye ne-angiography ziyi-test cisters (i-flexible long tubes), zidluliselwa kwimithambo yegazi kunye nentliziyo, ukuze kuhlolwe i-anatomy kunye nomsebenzi wentliziyo kunye nemithambo yegazi ejikelezayo.
Ngenxa yokuba ulwazi oluninzi luncedo lunokufumaneka kule mivavanyo, lwenziwa kuzo zonke izigulane ezicatshangelwa ukuhlinzwa komzimba kwanoma yiluphi uhlobo, kubandakanya ukuhlinzwa ngonyango , okanye i- angioplasty kunye ne- stenting .
I-Catheterization eyenziwa njani?
Umntu onaloo mvavanyo ku-laboratory ekhethekileyo yokutya, kwaye ufakwa kwitafile ekhethekileyo yoviwo. Emva kokuba i- anesthesia yendawo inikezwe, i-catheter ifakwe kwimithambo yegazi kwi-groin, ingalo, isandla okanye intamo. I-catheter ifakwe okanye ngokufakela encinci, okanye nge-stick-stick. Ngamanye amaxesha, ii-catheters zifakwe kwiziko elingaphaya kwesinye. Ngesinye imilambo yegazi, i-catheters iqhubekele entliziyweni isebenzisa i-x-ray isikhokelo.
Ngethuba le nkqubo, i-catheters iqhutywe kwiindawo ezahlukahlukeneyo ngaphakathi kwentliziyo, kwaye iingcinezelo eziphantsi kwamagumbi athile entliziyo zilinganiswa. Ukulinganisa ezi ngcinezelo zengcinezelo kunokunceda kakhulu ekuhloleni iintlobo ezithile zesifo senhliziyo. Ngokomzekelo, isifo se-valve senhliziyo singabonwa ngokulinganisa ukunyanzeliswa kwengcinezelo phakathi kwamagumbi ezinhliziyo. Ngokomzekelo, kwi- mitral stenosis ukuxinzelelo kwe-arrivals ekhohlo kuphezulu kunexinzelelo lwe-ventricular ekhohlo xa i-valral mitral evulekile, ebonisa ukuba i-valve ayivuli ngokupheleleyo, kwaye ukukhutshwa okukodwa kwegazi kukhoyo xa kungenjalo.
Iisampuli zegazi zingathathwa kwi-catheter ezivela kwiindawo ezahlukeneyo entliziyweni, ukwenzela ukulinganisa inani le-oksijini egazini. Amanqanaba e-oksijeni kwicala lasekunene lentliziyo kufuneka liphele, ngelixa i-oksijeni yamanqanaba kwicala lasekhohlo lentliziyo (emva kokuba igazi lidlule emiphakeni) lizaliswe.
Ukuhluka okungaqhelekanga kwi-oksijini yegazi kwiindidi ezahlukeneyo zentliziyo kunokubonisa ukuba "shunt," okanye ukugeleza kwegazi okungavamile ngaphakathi kwentliziyo, ngokuqhelekileyo kubangelwe iintsilelo zesifo senhliziyo esinjengenkunkuma ye-septal defect .
Ekugqibeleni, ngokufaka idayi ngekathetha ngelixa uluhlu lweemifanekiso ze-x-ray zibhalwa, "iifrimu" zingenziwa ngegazi eligeleza kwiigumbi zengqondo, okanye nge- artery corridary - inkqubo ebizwa ngokuba yi- angiography (ebizwa ngokuba arteriography).
Emva kokuba inkqubo igqityiwe, i-catheter (s) isuswe. Ukuhlamba kulawulwa ngokubeka uxinzelelo kwisiza sokufaka indawo yesikhala sokufumana imizuzu engama-30 ukuya kwimizuzu engama-60.
Yintoni ICatheterism yeCardiac isetyenziselwa?
I-catheterization ye-cardiac kunye ne-angiography ingabonisa ulwazi olubalulekileyo malunga nomsebenzi wenyama yonke, malunga nomsebenzi wendawo yamagumbi e-cardiac, malunga neentsimbi zomoya (nokuba zincinci - okanye ziphosakele kakhulu-ukubuyiswa kwakhona), malunga nokukhubazeka kwentliziyo, kunye indawo kunye nobunzima beempawu zokuthintela kwimibhobho ye-coronary .
Maxa wambi i-catheterization yenyama ingasetyenziselwa ukuhambisa unyango lweengxaki ezahlukeneyo zeentliziyo. I-catheterizations yezokwelapha iquka iinkqubo zokwelapha i-mitral stenosis okanye i- aortic stenosis , iinkqubo zokuvala i- patent foramen ovale , kwaye kunjalo, iinkqubo zokuphelisa iimbalo ze-coronary arteries (i-angioplasty kunye nokufakwa kwe-stent).
Ziziphi izingozi zeCatheter Catheterization kunye neAngography?
I-catheterization ye-cardiac kunye ne-angiography zikhuselekile, kodwa ngenxa yokuba ziyimigaqo echaphazela intliziyo, kukho iingxaki ezininzi. Ngenxa yalesi sizathu akukho mntu kufuneka abe ne-cardiac catheterization ngaphandle kokuba kunokwenzeka ukuba ulwazi olufunyenweyo kule nkqubo luya kuba luncedo olukhulu.
Inkathazo encinci ye-catheterization yenyama iquka ukuphuma kwamanzi kwisayithi lokufakela i-catheter, ukuphazamiseka kwesigxina sentliziyo ebangelwa yi-catheter ecasula intliziyo yesimo, kunye nokutshintsha kwexeshana kwixinzelelo legazi.
Iingxaki ezibaluleke ngakumbi zibandakanya ukugqithisa kwindonga yentliziyo (kubangela imeko ebungozi yobomi ebizwa ngokuthi i- tamponade ye-cardia ), ukukhutshwa ngokukhawuleza kwe-artery coronary (ekhokelela ekuhlaselweni kwentliziyo ), ukuphuma kwegazi ngokubanzi, ukuphaphaza, okanye ukusabela okubonakalayo kwidayi esetyenziswa kwi-angiography .
Ukongezelela, i-catheterization ye-cardiac kunye ne-angiography idinga ukufikelela kwindawo ethile. Njengoko naluphi na uvavanyo lwezonyango usebenzisa i-radiation, i-catheterization ye-cardiac inokuvelisa ukwanda okwenziwe kumngcipheko wokuphila komhlaza.
ILizwi
I-catheterization ye-cardiac kunye ne-angiography iyingozi yokuhlola i-cardiac tests ezinokuba luncedo kakhulu ekuhloleni iintlobo ezininzi zesifo senhliziyo, kunye nokucwangcisa kwanokuhambisa unyango.
