ʻO nā ala nui ʻelua e lawe mai i ke koko i ko mākou puʻuwai: ʻO nā mea āpau e pili ana i ka Vena Cava!

Ua noʻonoʻo paha ʻoe pehea e hiki ai ke koko i loko o ko kākou kino i ka puʻuwai a laila hoʻi i ke koena o ke kino? He hana kupaianaha ia. I kēia lā e kamaʻilio mākou e pili ana i kahi ʻano koʻikoʻi o nā aʻa nui e kōkua ana i kēia hana. Ua kapa ʻia ʻo Vena Cava . Ua lohe paha ʻoe iā ia ma mua. E nānā kākou i ke ʻano o ia mea, kāna hana, a me nā pilikia e hiki ai ke hana.

He aha ka Vena Cava?

I ka ʻōlelo maʻalahi, ʻo ka Vena Cava he ʻelua mau aa koko nui loa i loko o ko kākou kino. Hōʻiliʻili lākou i ke koko i hoʻohana ʻia, nele i ka oxygen mai nā ʻāpana like ʻole o ko kākou kino a hoʻihoʻi iā ia i ka ʻaoʻao ʻākau o ka puʻuwai. E noʻonoʻo iā ia e like me ʻelua mau aa koko nui e hoʻihoʻi i ke koko i hoʻohana ʻia i ka puʻuwai e hoʻomaʻemaʻe ʻia.

ʻElua ʻano o Vena Cava:

1. Superior Vena Cava (SVC): Lawe kēia i ke koko nele i ka oxygen mai ka ʻaoʻao o luna o ko mākou kino, ʻo ia hoʻi, mai nā ʻāpana ma luna o ka umauma (ma luna o ka diaphragm) (no ka laʻana, ke poʻo, ka ʻāʻī, a me nā lima), hoʻi i ka puʻuwai. ʻO kēia ka lua o ka aa nui loa i loko o ko mākou kino.

2. Inferior Vena Cava (IVC): ʻO kēia ke aʻa koko nui loa i loko o ko kākou kino. Lawe ia i ke koko nele i ka oxygen mai nā ʻāpana haʻahaʻa o ko kākou kino, ʻo ia hoʻi, mai nā ʻāpana ma lalo o ka umauma (ma lalo o ka diaphragm) (no ka laʻana, nā wāwae, nā ʻōpū) a i ka puʻuwai.

E noʻonoʻo e like me ke ala kaʻa. ʻO nā aa liʻiliʻi e puka mai ana mai nā ʻāpana haʻahaʻa o ko kākou kino (e like me nā puʻupaʻa, ke akepaʻa, a me ka spleen) ua like ia me nā kaʻa ma ke laina kūlanakauhale. ʻO ke koko deoxygenated a pau mai kēia mau kaʻa e hui pū i loko o kahi kaʻa nui i kapa ʻia ʻo ka inferior vena cava (IVC) . ʻO kēlā kaʻa ka mea e lawe i kēia koko i ka puʻuwai.

Eia kekahi, ʻo nā aa koko e puka mai ana mai nā ʻaoʻao o luna o ko kākou kino (e.g., ka umauma o luna, ke kua o luna) ua like ia me nā kaʻa ma ka Uptown Line. ʻO ke koko deoxygenated e puka mai ana mai kēia mau kaʻa e hui pū me kahi kaʻa nui i kapa ʻia ʻo Superior Vena Cava (SVC) . Hele pū kēlā i ka puʻuwai. ʻO ka puʻuwai ke kikowaena nui, a i ʻole kahi e hele ai, kahi e hui ai ke koko deoxygenated e puka mai ana mai kēia mau laina āpau, ma ke kikowaena kūlanakauhale a me ke kūlanakauhale o luna. Maopopo iā ʻoe?

He aha ka mea e hana maoli ai i ka Vena Cava?

ʻO ka hana nui loa o ka vena cava kiʻekiʻe (SVC) a me ka vena cava kiʻekiʻe (IVC) ʻo ia ka lawe ʻana i ke koko i nele i ka oxygen i ka atrium ʻākau o ko kākou puʻuwai. Mai laila mai, hele kēlā koko i ka ventricle ʻākau o ka puʻuwai. A laila, mai ka ventricle ʻākau mai, hoʻouna ʻia kēia koko i nā māmā ma o ke aʻa pulmonary .

ʻO nā māmā kahi e wehe ʻia ai ke kalapona ʻokikene i loko o ke koko a hoʻohui ʻia ka oxygen hou i ke koko. Ua like ia me ka hoʻohou ʻana i ke koko. A laila hoʻihoʻi ʻia ke koko oxygen hou i ka atrium hema o ka puʻuwai ma o nā aʻa pulmonary .Mai laila mai, hele ke koko i ka ventricle hema , a mai laila mai, hoʻolaha ʻia i loko o ke kino ma o ka aorta . E nānā i ke ʻano paʻakikī, akā ua hoʻonohonoho pono ʻia, o ka ʻōnaehana!

Aia i hea ka Vena Cava?

Aia kēia mau aa koko nui ʻelua, ʻo ia hoʻi ka inferior vena cava (IVC) a me ka superior vena cava (SVC), ma ka ʻaoʻao ʻākau o ko kākou puʻuwai .

Hoʻohui ʻia ko kākou mau aa koko ʻākau a me hema (i kapa ʻia hoʻi he mau aa koko brachiocephalic ) e hana i ka superior vena cava (SVC) . Aia kēia SVC ma ka ʻākau o ka sternum , ka iwi ma waenakonu o ko kākou umauma. Hoʻopili pololei ia i ka atrium ʻākau o ka puʻuwai.

ʻOi aku ka lōʻihi o ka vena cava haʻahaʻa (IVC) . Hoʻomaka ia ma ko kākou ʻōpū, kahi e hui ai nā aʻa iliac maʻamau ʻākau a me hema. Mai laila mai, piʻi ia i ka atrium ʻākau o ka puʻuwai.

Pehea ke ʻano o ka Vena Cava? Pehea kona nui?

ʻO ka vena cava kiʻekiʻe (SVC) he aa nui ia ʻaʻohe ona mau valves i loko.

He aa nui a lōʻihi hoʻi ka inferior vena cava (IVC) , akā hoʻokahi wale nō kona valve kahi e pili ai i ka atrium ʻākau o ka puʻuwai.

ʻO kēia nā aa koko nui loa i loko o ko mākou kino.

• ʻO ka vena cava kiʻekiʻe (SVC) he 7 kenimika ka lōʻihi (kokoke i 3 ʻīniha) a ma kahi o 2 kenimika (ʻoi aku ka liʻiliʻi ma mua o hoʻokahi ʻīniha) ka laulā.
• ʻO ka inferior vena cava (IVC) he 100 millimeters (ma kahi o 4 ʻīniha) ka lōʻihi a ma kahi o 22 millimeters (ʻaneʻane hoʻokahi ʻīniha) ke anawaena.

He aha nā mea i hana ʻia ai kēia mau mea?

ʻO ka vena cava kiʻekiʻe (SVC) a me ka vena cava haʻahaʻa (IVC) nā mea nui i hana ʻia mai:

• Nā pūnaewele Endothelial: Kōkua kēia i ka hoʻololi ʻana i nā meaʻai me nā ʻiʻo.
• ʻIʻo hoʻohui: Hāʻawi kēia i ke kākoʻo i nā aa koko.
• Nā olonā aʻalolo.
• ʻUala elastic: ʻO kēia nā mea e hāʻawi ai i nā aa i ko lākou ʻano kīkoʻo.
• ʻIʻo ʻiʻo.

He aha nā kūlana maʻamau e hoʻopilikia ai i ka Vena Cava?

I kekahi manawa, hiki ke loaʻa kahi ālai ʻia i loko o ka vena cava kiʻekiʻe (SVC) a i ʻole ka vena cava kiʻekiʻe (IVC). Hoʻopilikia kēia i ke kahe koko. Ua kapa ʻia kēia ʻano ʻo Superior Vena Cava Syndrome a i ʻole Inferior Vena Cava Syndrome , ma muli o ka ʻāpana i ālai ʻia.

Aia kekahi mau kumu nui no kēia mau ālai ʻana:

• He puʻupuʻu: no ka laʻanaHiki i ke kanesa o ka māmā , a i ʻole kekahi ʻano kanesa ʻē aʻe, ke pālahalaha a hoʻopili i kēia mau aa koko.
• Nā ʻūpā koko: I kekahi manawa hiki ke hana ʻia nā ʻūpā koko i loko o ka vena cava kiʻekiʻe i nā poʻe me nā catheters venous waena a i ʻole nā ​​​​pacemakers .
• ʻO ka maʻi hānau ʻole: ʻO ia hoʻi kahi mea i hana pono ʻole ʻia i loko o ka ʻōpū.

He aha nā hōʻailona o kahi pilikia me ka Vena Cava?

Ke hoʻopaʻa ʻia ka vena cava kiʻekiʻe (SVC) a i ʻole ka vena cava haʻahaʻa (IVC) e kekahi mea, a i ʻole ke ālai ʻia ke kahe koko mai loko mai, nā hōʻailona e like me:

Nā hōʻailona o ka Superior Vena Cava Syndrome (pale a ʻūlū paha):

• Ka pehu ʻana o ke kino o luna (maka, ʻāʻī, lima).
• Pōkole o ka hanu.
• ʻAngina ( ʻeha umauma).

Nā hōʻailona i hoʻokumu ʻia e ke koko a i ʻole ka puʻupuʻu i loko o ka vena cava kiʻekiʻe (SVC):

• Ka pehu ʻana ma ke kino o luna.
• Pōkole o ka hanu.

Nā hōʻailona o kahi ʻōpū koko i loko o ka vena cava haʻahaʻa (IVC):

• Ka pehu ʻana o nā wāwae.
• ʻEha hope.
• Piʻi ke kaumaha.
• ʻEha nui ma nā wāwae.

Nā hōʻailona i hoʻokumu ʻia e kahi puʻupuʻu ma ka vena cava inferior (IVC):

• ʻEha ʻōpū.
• Ka pehu ʻana o nā wāwae.
• Ka emi ʻana o ke kaumaha.

Nā hōʻailona o ka Inferior Vena Cava Syndrome (pale a hoʻopaʻa paha):

• Ke koko haʻahaʻa.
• Ka pehu ʻana ma ke kino haʻahaʻa.
• Tachycardia (puʻuwai wikiwiki).

Mea nui: Inā loaʻa iā ʻoe kekahi a ʻoi aku paha o kēia mau hōʻailona, ​​e ʻike koke i ke kauka. Hiki i kēia ke lilo i mau hōʻailona o nā maʻi ʻē aʻe, no laila he mea nui e ʻike pono i ke kumu.

He aha nā hoʻokolohua e hana ʻia e nānā i ke olakino o ka Vena Cava?

He nui nā hoʻokolohua a kāu kauka e nānā ai i ke kūlana o ka Vena Cava. ʻO kekahi o lākou:

• ʻO ke kiʻi X-ray o ka umauma (hoʻohana ʻia kēia e nānā i ka vena cava kiʻekiʻe).
• ʻO ka angiography Coronary (hiki i kēia ke nānā aku i ka vena cava kiʻekiʻe).
• Hoʻokolokolo ʻana o ka ultrasound.
• Hoʻāʻo CT Scan (CT - Computed Tomography).
• Hoʻāʻo MRI scan (MRI - Magnetic Resonance Imaging).
• ʻO ka venography a i ʻole ka phlebography (he X-ray kēia o nā aa koko, akā ʻaʻole hoʻohana nui ʻia i kēia manawa).

He aha nā lāʻau lapaʻau no nā pilikia e pili ana i ka Vena Cava?

I ka mālama ʻana i kahi pilikia me ka vena cava superior (SVC) a i ʻole ka vena cava inferior (IVC), hoʻohana pinepine ʻia nā ʻano lapaʻau like.

• Hiki ke hāʻawi ʻia nā diuretics ( nā lāʻau lapaʻau e hoʻonui ai i ka mimi) a i ʻole nā ​​​​steroids e mālama i ka pehu.
• Hiki ke hāʻawi ʻia nā steroids , thrombolytics (nā lāʻau hoʻoheheʻe koko), a me nā anticoagulants (nā lāʻau pale koko) e mālama i nā mea ālai e like me nā ʻūpā koko.
• Hiki ke wehe ʻia kahi ʻūpā koko me ka hoʻohana ʻana i kahi catheter .
• Inā ua haiki ke aʻa (stenosis) ma muli o ke koko ʻaʻa, hiki ke hana ʻia ka angioplasty (ke kaomi ʻana i ka mea e ālai ʻia ai i ka paia o ke aʻa) a hiki ke hoʻokomo ʻia kahi stent ( kahi ʻōmole metala liʻiliʻi).
• Inā he ʻūpē koko a he puʻupuʻu paha , hiki ke hana ʻia ke ʻoki bypass .
• Inā he puʻupuʻu, hiki ke wehe ʻia ma ke ʻoki ʻana.
• Hiki ke hāʻawi ʻia ka chemotherapy a i ʻole ka radiation therapy e mālama i nā ʻōpū.

Eia kekahi, inā loaʻa iā ʻoe ka Deep Vein Thrombosis (DVT) (kahi kūlana e hana ʻia ai nā ʻōpū koko ma nā wāwae) a aia i ka pilikia o kahi ʻōpū koko e hele ana mai nā wāwae a i ʻole pelvis i nā māmā (i kapa ʻia he pulmonary embolism (PE) , hiki i kāu kauka ke hoʻoholo e hoʻokomo i kahi kānana Vena Cava . Hoʻopaʻa kēia kānana i nā ʻōpū koko a kāohi iā lākou mai ka hele ʻana i nā māmā.

Pehea e mālama ai i kou Vena Cava i ke olakino?

E like me nā kīʻaha koko ʻē aʻe i loko o kou kino, hiki iā ʻoe ke mālama i kēia Vena Cava.

• E ʻai i ka meaʻai olakino haʻahaʻa i ka momona paʻa.
• E hoʻoikaika kino i nā manawa a pau.
• E hōʻemi i ke kaumaha.
• Kaohi i nā kūlana e like me ke koko kiʻekiʻe , ka cholesterol kiʻekiʻe, a me ka maʻi diabetes mellitus .

ʻO ka mea hope loa, ʻo ka mea nui loa

Inā loaʻa iā ʻoe kahi paʻa i loko o ka vena cava kiʻekiʻe (SVC) a i ʻole ka vena cava kiʻekiʻe (IVC), he nui nā koho a kāu kauka no ka mālama ʻana. E kamaʻilio me ia e pili ana i ka lāʻau lapaʻau maikaʻi loa no kou kūlana. Inā kuhikuhi kāu kauka i ka lāʻau lapaʻau, e lawe pololei e like me ke kuhikuhi ʻana. Inā ua loaʻa iā ʻoe kekahi ʻoki kino a i ʻole kekahi lāʻau lapaʻau ʻē aʻe, e mālama pono i nā manawa a kāu kauka a hiki i kou hoʻōla piha ʻana. Aia kou olakino ma kou mau lima!

ʻO Vena cava, puʻuwai, kahe koko, nā aʻa koko, koko nele i ka oxygen, vena cava kiʻekiʻe, vena cava haʻahaʻa
