ʻO ultrasound Cardiac intravaskia

ʻO kahi ultrasound Intravascular (IVUS) kahi hōʻike diagnostic. Hoʻohana kēia hoʻokolohua i nā nalu kani e ʻike i loko o nā kīʻaha koko. He mea pono ia no ka loiloi i nā aʻa coronary e hoʻolako i ka puʻuwai.

Hoʻopili ʻia kahi mea kani ultrasound liʻiliʻi i ka piko o kahi ʻōmole lahilahi. Kapa ʻia kēia paipu he catheter. Hoʻokomo ʻia ka catheter i loko o ke aʻa o kou ʻūlū a neʻe i luna i ka puʻuwai. ʻOkoʻa ia mai ka ultrasound duplex maʻamau. Hana ʻia ʻo ultrasound Duplex mai waho o kou kino ma ke kau ʻana i ka transducer ma ka ʻili.

Ana kahi kamepiula pehea e hōʻike ai nā nalu kani i nā kīʻaha koko, a hoʻololi i nā nalu kani i nā kiʻi. Hāʻawi ʻo IVUS i ka mea mālama ola i ka nānā ʻana i nā aʻa o kou coronary mai loko mai.

ʻAneʻane hana ʻia ʻo IVUS i ka wā o ke kaʻina hana. Nā kumu no ke aha e hana ʻia ai e hoʻopili ʻia:

• Ke kiʻi ʻana i ka ʻike e pili ana i ka puʻuwai a i ʻole kāna aʻa koko a i ʻole e ʻike inā pono ʻoe i kahi ʻoki puʻuwai
• Ke mālama nei i kekahi ʻano o nā ʻano puʻuwai

Hāʻawi ka Angiography i kahi nānā maʻamau i nā aʻa coronary. Eia naʻe, ʻaʻole hiki ke hōʻike i nā paia o nā aʻa. Hōʻike nā kiʻi IVUS i nā paia artery a hiki ke hōʻike i ka cholesterol a me nā waihona momona (plaques). Hiki i ke kūkulu ʻana i kēia mau waihona ke hoʻonui i kou makaʻu no ka puʻuwai puʻuwai.

Ua kōkua ʻo IVUS i nā mea hoʻolako e hoʻomaopopo pehea e lilo ai nā stents i clogged. Kapa ʻia kēia stent restenosis.

Hana ʻia ʻo IVUS e hōʻoia i ke kau pololei ʻia ʻana o kahi stent i ka manawa o ka angioplasty. Hana ʻia paha e hoʻoholo i kahi e kau ai kahi stent.

E hoʻohana ʻia ʻo IVUS i:

• E nānā i ke aorta a me ke ʻano o nā paia aʻa, i hiki ke hōʻike i ke kūkulu ʻana i nā pā
• E ʻike i nā kīʻaha koko i pili i ka dissection aorta

Aia kekahi pilikia iki no nā pilikia me ka angioplasty a me ka catheterization puʻuwai. Eia naʻe, palekana loa nā hoʻāʻo ke hana ʻia e kahi kime ʻike. Hoʻohui ʻo IVUS i kahi makaʻu hou aʻe.

Nā pilikia o ka anesthesia a me ke kahakaha ʻana ma:

• Nā hopena i nā lāʻau
• Nā pilikia hanu
• Kahe ʻana o ke kahe, kahe koko
• Maʻi kīnā

ʻO nā pilikia ʻē aʻe e:

• ʻO ka hōʻino i kahi kīʻaha puʻuwai a i ʻole kīʻaha koko
• Maʻi hohola
• Kuʻi naʻau kaulike (arrhythmia)
• ʻO ke kōpaʻa kīnā ʻole (ʻoi aku ka kiʻekiʻe o ka makaʻu i ka poʻe i loaʻa i nā pilikia puʻuwai a i ʻole ka diabetes
• Hahau (kākaʻikahi kēia)

Ma hope o ka hoʻāʻo, hemo loa ka catheter. Kau ʻia kahi bandage ma ia wahi. E noi ʻia ʻoe e moe palahalaha ma kou kua me ka kaomi ma kou ʻūlū no kekahi mau hola ma hope o ka hoʻāʻo e pale i ke kahe ʻana o ke kahe.

Inā hana ʻia ʻo IVUS i ka wā:

• Kāleka Cardiac: E noho ʻoe i ka haukapila ma kahi o 3 a 6 mau hola.
• Angioplasty: E noho ʻoe i ka haukapila no 12 a 24 mau hola.

ʻAʻole hoʻohui ka IVUS i ka manawa e pono ai e noho i ka haukapila.
