Pulmonary ventilation / perfusion scan

ʻO ka pulmonary ventilation / perfusion scan e pili ana i ʻelua mau hoʻokolohua scan nukilika e ana i ka hanu ʻana (ventilation) a me ka holo ʻana (perfusion) ma nā wahi āpau o nā māmā.

ʻO ka hoʻomaʻemaʻe pulmonary ventilation / perfusion he 2 mau ho'āʻo. Hana ʻokoʻa ʻia a hui pū paha lākou.

I ka wā o ka perfusion scan, hāʻawi kahi mea mālama ola i ka albumin radioactive i loko o kou aa. Kau ʻia ʻoe ma luna o kahi pākaukau hoʻoneʻe ma lalo o ka lima o kahi scanner. Nānā ka mīkini i kou mau māmā i ke kahe ʻana o ke koko ma o lākou e ʻike i kahi o nā ʻāpana radioactive.

I ka nānā ʻana o ka ea, hanu ʻoe i ke kinoea radioactive ma o ka pale maka i kou wā e noho ana a e moe ana paha i ka papa ma lalo o ka lima scanner.

ʻAʻole pono ʻoe e hōʻoki i ka ʻai ʻana (wikiwiki), ma kahi papaʻai kūikawā, a i ʻole lawe i nā lāʻau i mua o ka hoʻāʻo.

Hana ʻia kahi x-ray umauma ma mua a ma hope paha o kahi ea a me ka perfusion scan.

Hōʻaʻahu ʻoe i ke kapa komo haukapila a i ʻole nā ​​lole ʻoluʻolu i loaʻa ʻole nā ​​mea hoʻopaʻa kila.

ʻIke paha ka papa ʻaina a anuanu paha. ʻIke paha ʻoe i kahi ʻōkuʻu ʻoi loa ke kau ʻia ka IV i ke aa i kou lima no ka ʻāpana perfusion o ka scan.

Hoʻohana ʻia ka makakiʻi i ka nānā ʻana o ka ea i kou hopohopo e pili ana i kahi wahi liʻiliʻi (claustrophobia). E moe mālie ʻoe i ka nānā ʻana.

ʻAʻole hoʻokumu ka pahu radioisotope i ka maʻamau.

Hoʻohana ʻia ka scan ea e ʻike ai i ke ʻano o ka neʻe ʻana o ka ea a kahe ke koko ma waena o nā akemāmā ʻO ke aniani perfusion ke ana i ka lako o ke koko ma o nā māmā.

Hana pinepine ʻia kahi ea a me ka scan perfusion e ʻike i kahi embolus pulmonary (kōkuʻu koko i nā akemāmā). Hoʻohana ʻia ia i:

• Kuhi i ka holo maʻamau (shunts) i nā kīʻaha koko o nā akemāmā (nā moku pulmonary)
• Hōʻike i nā wahi āpana (ʻokoʻa nā wahi māmā) ka hana o ka māmā i ka poʻe me ka maʻi pulmonary holomua, e like me COPD

Pono ka mea hāʻawi i kahi ea a me ka scan perfusion a laila loiloi iā ia me kahi x-ray umauma. Pono nā ʻāpana āpau o nā māmā ʻelua e lawe kaulike i ka radioisotope.

Inā piʻi i lalo nā māmā ma lalo o ka nui maʻamau o radioisotope i ka manawa o ka ea a i ʻole ka perfusion scan, ma muli paha o kekahi o kēia mau mea:

• Pāpale alanui
• ʻO ka maʻi pulmonary obstructive maʻi (COPD)
• Pulumonia
• Ka hoʻopili ʻana o ke aʻa aʻa
• Pneumonitis (pehu o nā ake māmā no ka hanu ʻana i kahi mea haole)
• Embolus pulmonary
• Hoʻoemi i ka hanu a me ka hiki o ka ea

Ua like nā pōpilikia me nā x-ray (radiation) a me nā kui kui.

ʻAʻohe radiation e hoʻokuʻu ʻia mai ka scanner. Akā, ʻike ia i ka radiation a hoʻololi iā ia i kiʻi.

Aia kahi liʻiliʻi e hōʻike i ka pāhawewe mai ka radioisotope. Hoʻohana pōkole nā ​​radioisotopes i ka wā scans. Haʻalele nā ​​radiation a pau i ke kino i kekahi mau lā. Eia nō naʻe, e like me ka hōʻike ʻana o ka pāhawewe, aʻoaʻo ʻia ka makaʻala no nā wahine hāpai a hānai paha.

Aia kekahi pilikia iki no ka maʻi a i ʻole ke kahe ʻana ma ka pūnaewele kahi i hoʻokomo ʻia ai ka nila. ʻO ka makaʻu me ka scan perfusion ka mea like me ka hoʻokomo ʻana i kahi nila kuʻi no kekahi kumu ʻē aʻe.

I nā hihia kakaʻikahi, hiki i kekahi kanaka ke hoʻomohala i kahi alapiʻi i ka radioisotope. Hoʻopili paha kēia i kahi hopena anaphylactic koʻikoʻi.

ʻO ka pulmonary ventilation a me ka perfusion scan hiki ke lilo i kahi koho haʻahaʻa haʻahaʻa i ka angiography pulmonary no ka loiloi ʻana i nā maʻi o ke kahe o ke koko.

ʻAʻole hiki i kēia hoʻāʻo ke hāʻawi i kahi kuhi definite, keu hoʻi i ka poʻe me ka maʻi lolo. Pono paha nā hoʻokolohua ʻē aʻe e hōʻoia a kāpae paha i nā hopena o kahi ea pulmonary a me ka scan perfusion.

Ua hoʻololi nui ʻia kēia hōʻike e CT pulmonary angiography no ka diagnose pulmonary embolism. Eia nō naʻe, hiki i nā poʻe me nā pilikia puʻupaʻa a i ʻole ka allergy e hoʻohālikelike i ke kala ke loaʻa palekana i kēia hōʻike.
