Njira za Mtima Zimagwiritsidwa Ntchito Kuthetsa Mavuto Amtundu Wambiri
Catheterization ya cardiac ndi angiography ndizovuta zowunikira mayesero omwe ma catheters (omwe amatha kusintha mosavuta, timapapu ting'onoting'ono) amadutsa m'mitsempha ya mitsempha ndi m'mtima, kuti tifufuze momwe thupi ndi mitsempha yowzungulira imayendera.
Chifukwa chakuti zowonjezereka zowonjezereka zitha kupezeka ku mayeserowa, zimagwiritsidwa ntchito pafupifupi odwala onse omwe akuganiziridwa chifukwa cha opaleshoni ya mtima yamtundu uliwonse, kuphatikizapo opaleshoni , kapena angioplasty ndi stenting .
Kodi Catheterization Yachitika Bwanji?
Munthu yemwe ali ndi mayesero awa ndi labotale yapadera yokhala ndi kanyumba, ndipo akuyikidwa pa tebulo lapadera. Pambuyo popatsidwa anesthesia , kathete imalowetsedwa mu mitsempha ya mitsempha pamphuno, mkono, mkono kapena khosi. Catheter imalowetsedwa kupyolera mu kapangidwe kakang'ono, kapena pogwiritsa ntchito ndodo ya singano. Nthawi zina, catheters amachokera ku malo amodzi. Kamodzi mu mitsempha ya mitsempha, catheters yapita patsogolo pamtima pogwiritsa ntchito x-ray.
Panthawiyi, catheters nthawi zambiri amayendetsedwa kumalo osiyanasiyana mkati mwa mtima, ndipo zovuta mkati mwa zipinda zosiyanasiyana za mtima zimayesedwa. Kuyeza mavuto awa osakayika kungathandize kwambiri pakupeza matenda ena amtima. Mwachitsanzo, matenda a valve yamtima amatha kupezeka poyeza kusiyana kwa kusiyana pakati pa zipinda za mtima. Mwachitsanzo, mu mitral stenosis , kumapeto kwa mphamvu ya atriyali yapamwamba kwambiri kuposa mphamvu ya kumapeto kwa ventricular pamene mitsempha yamagetsi imatseguka, zomwe zimasonyeza kuti valve sikutseguka kwathunthu, komanso kuti chitetezo chochepa cha magazi chikapezeka pamene sichingakhalepo.
Zitsanzo zamagazi zimatha kutengedwa kudzera mu catheter kuchokera kumadera osiyanasiyana mu mtima, kuti azindikire kuchuluka kwa mpweya m'magazi. Mafuta a oksijeni kumbali yowongoka ya mtima ayenera kuchotsedwa, pamene ma oksijeni omwe ali kumbali ya kumanzere ya mtima (pambuyo poti magazi adutsa m'mapapu) adzalandidwanso.
Kusiyana kwakukulu kwa magazi m'magulu osiyanasiyana a mtima kungasonyeze "shunt," kapena kutuluka mwazi kwabwino mkati mwa mtima, kawirikawiri zimayambitsidwa ndi zofooka za mtima monga matenda a atrial septal .
Pomaliza, pobaya jekeseni kudzera mu catheter pomwe zithunzi zojambula bwino zowonongeka zalembedwa, "mafilimu" amatha kupangidwa ndi magazi omwe akuyenda kudzera m'zipinda za mtima, kapena kudzera m'mitsempha yamakono - njira yotchedwa angiography (yotchedwanso arteriography).
Mukamaliza kukonza, catheter (s) ikuchotsedwa. Kutsekemera kumayang'aniridwa mwa kuyika kukakamizidwa pa malo oika kathetera malo 30 - 60 minutes.
Kodi Catheterization ya Cardiac Imagwiritsidwa Ntchito Bwanji?
Catheterization ya cardiac ndi angiography zingathe kuwunikira mfundo zofunika zokhudzana ndi ntchito ya mtima, zokhudzana ndi magulu a mtima wamtima, za valve za mtima (ngati ziri zochepa kwambiri - stenosis - kapena zowopsya - kubwezeretsedwa), zokhudzana ndi zofooka za mtima, ndi za malo ndi zolimba za mabomba mu mitsempha yamakono .
Nthawi zina catheterization ya mtima ikhoza kugwiritsidwa ntchito popereka mankhwala osiyanasiyana. Catheterizations ochiritsira amagwiritsa ntchito njira zothandizira mitral stenosis kapena aortic stenosis , njira zothetsera patent foramen ovale , ndipo ndithudi, njira zothandizira kuthetsa mitsempha mu mitsempha yotchedwa coronary arteries (angioplasty ndi stent placement).
Kodi Zowopsa za Catheterization ya Cardiac ndi Angiography?
Catheterization ya cardiac ndi angiography sizikhala zotetezeka, koma chifukwa ndi njira zosautsa zomwe zimakhudza mtima, zovuta zambiri zingatheke. Pa chifukwa ichi palibe munthu amene ayenera kukhala ndi catheterization ya mtima pokhapokha ngati pali chifukwa chodziwikiratu kuti zomwe mwapeza kuchokera ku ndondomekozi zidzakhala zopindulitsa kwambiri.
Zing'onozing'ono zowonongeka kwa mtima zimaphatikizapo kutuluka magazi pang'ono pamalo a catheter kuika, kusokonezeka kwapakati pa mtima chifukwa cha catheter kumapweteketsa mtima, komanso kusintha kwa kanthawi kochepa m'magazi.
Zovuta zowonjezereka zimaphatikizapo kuwonongeka kwa khoma lamtima (kuchititsa chiopsezo chotchedwa moyo chosokoneza mtima ), mwadzidzidzi kutsekedwa kwa mitsempha yaumphawi (yomwe imatsogolera ku matenda a mtima ), kutaya mwazi kwambiri, kupwetekedwa mtima , kapena kusokonezeka kwa dye yomwe imagwiritsidwa ntchito mu angiography .
Kuonjezerapo, catheterization ya mtima ndi angiography zimafuna kuwonetseredwa ndi mankhwala enaake. Mofanana ndi mayeso aliwonse a zamankhwala pogwiritsa ntchito ma radiation, catheterization ya mtima ingachititse kuwonjezeka kochepa pa moyo wanu nthawi zonse kuti mukhale ndi khansa.
Mawu Ochokera
Catheterization ya cardiac ndi angiography ndizovuta zowona mtima zomwe zingakhale zothandiza kwambiri pakupeza mitundu yambiri ya matenda a mtima, komanso pokonzekera komanso kupereka mankhwala.
