Izinhliziyo Zisetshenziswa Ukuphatha Izinkinga Zenhliziyo Ehlukahlukene
I-catheterization ye-cardiac kanye ne-angiography yizivivinyo ezingenangqondo zokuxilonga lapho izinhlayiya (ama-flexible, amashubhu amancane) adluliselwa emithanjeni yegazi nasenhliziyweni, ukuze ahlolisise ukuma nokusebenza kwenhliziyo nemithambo yegazi ezungezile.
Ngenxa yokuthi ulwazi oluwusizo oluningi lungatholakala kulezi zivivinyo, zenziwa cishe kuzo zonke iziguli ezicatshangelwa ukuhlinzwa komzimba kwanoma yiluphi uhlobo, kuhlanganise nokuhlinzeka nge-bypass , noma i- angioplasty ne- stenting .
Kwenziwa kanjani i-Catheterization?
Umuntu onalezi zivivinyo i-laboratories ekhethekile yokugaya izidakamizwa, futhi efakwe etafuleni elikhethekile lokuhlola. Ngemuva kwe-anesthesia yendawo , i-catheter ifakwa emithanjeni yegazi ku-groin, ingalo, isibindi noma intamo. I-catheter ingeniswa noma nge-incision encane, noma nge-stick-stick. Ngezinye izikhathi, ama-catheters afakwa kusuka kwisayithi engaphezu kweyodwa. Kanye emithanjeni yegazi, ama-catheter athuthukile enhliziyweni esebenzisa isiqondiso se-x-ray.
Phakathi nenqubo, ama-catheter ngokuvamile aqhutshwa ezindaweni ezihlukahlukene ngaphakathi kwenhliziyo, futhi izingcindezi ngaphakathi kwamakamelo ahlukahlukene enhliziyo zilinganiswa. Ukulinganisa lezi zincindezelo ezingenasifo sangasese kungasiza kakhulu ekuhloleni izinhlobo ezithile zesifo senhliziyo. Isibonelo, isifo se-valve senhliziyo singatholakala ngokukala ukuhlukana kwengcindezi phakathi kwamagumbi enhliziyo. Isibonelo, ku- mitral stenosis ukucindezela kwe-atrial kwesokunxele kuphakeme kunomshini we-ventricular wesokunxele lapho i-valve ye-mitral ivulekile, okubonisa ukuthi i-valve ayivuli ngokuphelele, nokuthi ukuvinjelwa okuyingxenye yokugeleza kwegazi kukhona uma kungenjalo.
Ama-sampuli egazi angathathwa phakathi kwe-catheter evela ezindaweni ezahlukene enhliziyweni, ukuze alinganise inani le-oksijini egazini. Amazinga e-oksijeni ohlangothini lwesokudla senhliziyo kufanele apheliswe, kuyilapho amazinga oksijini ehlangothini lwesobunxele senhliziyo (emva kokuba igazi lidlule emaphashini) seligcwalisiwe.
Ngakho ukuhluka okungajwayelekile e-oksijeni yegazi emagumbini ahlukahlukene e-cardiac kungabonisa ukuthi "shunt," noma ukugeleza kwegazi okungavamile ngaphakathi kwenhliziyo, ngokuvamile kubangelwa ukukhubazeka kwenhliziyo okuzalwa njengenhlamba ye- atrial septal .
Okokugcina, ngokufaka idayi ngokusebenzisa i-catheter ngenkathi kuqoshiwe izithombe eziningi ze-x-ray, "ama-movie" angenziwa ngegazi eligeleza egumbini lezinhliziyo, noma nge- artery coronary - inqubo eyaziwa ngokuthi i- angiography (ebizwa nangokuthi i- angiography i-arteriography).
Uma inqubo isiphelile, i-catheter (ama) isusiwe. Ukukhipha igazi kulawulwa ngokubeka ingcindezi endaweni yokufaka indawo yokugaya amaminithi angu-30 kuya kwangu-60.
Kuyini Ukusebenzisa I-Cardiac Catheterization?
I-catheterization ye-cardiac kanye ne-angiography ingabonisa ulwazi olubalulekile mayelana nokusebenza kwenhliziyo yonke, mayelana nokusebenza kwamagumbi omzimba womuntu ngamunye, mayelana namagagasi enhliziyo (kungakhathaliseki ukuthi amancane kakhulu - isifo esibucayi - noma ukuvuza okunamandla kakhulu), mayelana nokukhubazeka kwenhliziyo kwangempela indawo kanye nokuqina kwamabhulogiji emithanjeni ye-coronary .
Ngesinye isikhathi i-catheterization ye-cardiac ingasetshenziswa ukuletha ukwelashwa kwezinkinga ezihlukahlukene zenhliziyo. I-catheterizations yokwelashwa ihlanganisa izinqubo zokwelapha i-mitral stenosis noma i- aortic stenosis , izinqubo zokuvala i- patent foramen ovale , futhi-ke, izinqubo zokuqeda ukuvimbela emithonjeni ye-coronary (i-angioplasty kanye nokubekwa kwe-stent).
Yiziphi Izingozi Ze-Catheterization Ye-Cardiac ne-Angiography?
I-catheterization ye-cardiac kanye ne-angiography iphephile, kodwa ngoba iyindlela enonya ehilela inhliziyo, izinkinga eziningi zingenzeka. Ngenxa yalesi sizathu akekho umuntu okufanele abe ne-catheterization yenhliziyo ngaphandle kokuthi kube khona amathuba okuba ulwazi olutholakala enkambisweni luyoba nenzuzo enkulu.
Izinkinga ezincane zokwelashwa komzimba zihlanganisa ukuphuma kwamanzi endaweni yokufakwa kwe-catheter, ukuphazamiseka kwengqondo okwesikhashana okubangelwa i-catheter ecasula isisu senhliziyo, nezinguquko zesikhashana empilweni yegazi.
Izinkinga ezibaluleke kakhulu zihlanganisa ukuguqulwa kwodonga lwenhliziyo (kubangela isimo esongela ukuphila esibizwa ngokuthi i-tamponade ye-cardiac ), ukuvinjelwa okungazelelwe kwe-artery coronary (okuholela ekuhlaselweni kwenhliziyo ), ukuphuma kwegazi okukhulu, ukushaya isisu , noma ukusabela okwenziwe ngombala osetshenziswe ku-angiography .
Ngaphezu kwalokho, i-catheterization ye-cardiac kanye ne-angiography idinga ukutholakala komuthi othile. Njenganoma yikuphi ukuhlolwa kwezokwelapha esebenzisa imisebe, i-catheterization yomzimba ingaveza ukwanda okwempilo engozini yokuphila komdlavuza.
Izwi elivela
I-catheterization ye-cardiac kanye ne-angiography zihlasela izifo zenhliziyo ezingaba usizo kakhulu ekuhloleni izinhlobo eziningana zesifo senhliziyo, nasekuhleleni ngisho nokuletha ukwelashwa.
