Stenting o na moku o ka naau

No ka iapaau ana o coronary naau maʻi, a ua muli ma ka hou o ka coronary arteries (lākou e hānai ai i ka myocardium), i ka makahiki 1977 hoʻonui angioplasty o kēia mau moku, ua hana no ka manawa mua. Ma ka hapanui o na hihia, ke kumu hou o na arteries e momona hoʻokomo kālā ma luna o ka intima o ka moku, a hiki aku i ka lako hou i lawa no o oxygen i na cardiomyocytes. E like me ia i kaʻilihune, ka ulu 'angina a me myocardial infarction.

Hoʻonui angioplastyʻano hana ua ma muli o ka mea i ai i ka naau ma ka femoral artery hānai catheter ma ko lakou hope o Nyos i ka cuff (hoʻonui deflated). Ma lalo o X-Ray hooponopono catheter ua iiaeaaony pololei a hiki i ke kahua o ka hou, a laila, ua inflated ka hoʻonui - ka artery ua hoʻonui. Ka papa hana haawi maikai hualoaʻa, akā, pinepine relapse (artery hou-narrows, a me ka nui loa).

I mea e hohola aku i ka laulā o ka hoʻonui angioplasty, ua ulu kauka hou i ka iaoia - cardiac vascular stenting. A stent mea he mea hao omo hei, heʻano o kuhiliʻole kila ponoi. Loko o ka artery, ia Hoʻonui i ka pono,ʻaʻole hiki ia i ka spasm. Heart vascular stenting ua hanaʻia e kekahi mea a i waiwai. A nui ka uku hoopanee i stents i i kapa komo iā ia me ka polymeric mea a me ka lāʻau lapaʻau 'ona (e laʻa me, cytotoxic anticancer ai'). Stenting o na moku o ka naau ia catheters ke emi ka uku o ke kahua o atherosclerotic plaques. Akā, e pono ke kuai hoomanao ana ma ka hoʻohana 'ana i kēia mau stents i ka uku o ka hoola ana o ka pā paia o na arteries emi, a mea he ololi o ke thrombosis kamepiula.

Stenting o na moku o ka naau i like na like me hoʻonui angioplasty. Aia He hoʻokahi wale nō okoa ma ka hoʻonui stentʻia, lole komoʻuʻuku nona iwi. he catheter ka wā i hoʻolaunaʻia ma loko o ka coronary artery wahi ua wehe ', a laila inflate i ka hoʻonui, ke stent no straightening ka wahi kahi i artery ua hou. Penei, i ka hoomaka artery paia ua hoʻoikaika a me ka ikaika, mai loko.

Ma ka keia kahua o ka naau stents - ka papa haʻawina i coronary artery holo alaʻokoʻa pakuiia auanei lakou. It E e kaulana kekahi maikaʻi kēia lākiō o stenting: ka spasm o ka coronary arteries i hoʻonui angioplasty e kūkulu i kekahi myocardial infarction, i hiki ke käpae 'ma ka hoʻohana' ana i ka stent. Stenting o arteries o ka naau manawa - i kekahi koho iaoia o coronary artery holo alaʻokoʻa pakuiia auanei lakou. Eia hou, ina ma ka papa o ka hana o ka hoʻonui angioplasty coronary artery spazmiruyutsya, he mea hiki i ka hooulu ana o myocardial infarction, a me ka stent ma keia kulana kōkua i loaʻa i kēia complication nui. I ka coronary artery holo alaʻokoʻaʻoki kino hapalua o ka hoʻomanawanui iki mai hoʻomohala stenosis o ka shunt. Kona stenting mea he pono koho i ka puana coronary holo alaʻokoʻa. I mea'ōnaehana mānowai koko stents - i kekahi koho e thrombolysis, a me ka maikaʻi 'ike loea hou no ka iapaau ana o ka huʻi myocardial infarction' ana i loko o ka hora mua o kona ulu ana.

Eia naʻe, loaʻa nō contraindications no keia ina hana. Stent i hoʻokomo 'mea,ʻaʻole hiki i eiei hou o ka coronary arteries. Nō hoʻi, he insurmountable keʻakeʻa nei mea liʻiliʻi (emi o 2.8 mm) anawaena o ka hou artery.

No ka mea Kāohiʻana o thrombotic hanana i kēia ke kaʻina hana no ua hana ma luna o ke kāʻei kua o anticoagulants.

Ma hope o ia i ka hana, i ke ahonui i koe i loko o ka haukapila no ka 5-7 lā a puni ka huahelu, 'inikua hooponopono. Postoperatively mau antiplatelet a me ka anticoagulation Inc.
