Kua whakaaro koe me pēhea te rere o te toto i roto i tō tātou tinana ki te ngākau, kātahi ka hoki ki te toenga o te tinana? He tukanga whakamiharo tēnei. I tēnei rā ka kōrero tātou mō tētahi momo uaua nui tino nui e āwhina ana i tēnei mahi. Ko te Vena Cava tōna ingoa. Kua rongo pea koe i mua. Me titiro tātou ki tōna āhua, ki āna mahi, me ngā raruraru ka pā mai.
He aha te Vena Cava?
He whakarāpopototanga noa iho, ko ngā uaua nui e rua o roto i tō tātou tinana, ko te Vena Cava . Ka kohia e rātou te toto kua whakamahia, kāore i te whai hāora mai i ngā wāhanga rerekē o tō tātou tinana, ka whakahokia ki te taha matau o te ngākau. Whakaarohia he rite ki ngā uaua matua e rua e whakahoki ana i te toto kua whakamahia ki te ngākau kia horoia.
E rua ngā momo o te Vena Cava:
1. Te Vena Cava o te Runga Rawa (SVC): Ka haria e tēnei te toto kore-hāora mai i te taha whakarunga o tō tātou tinana, arā, mai i ngā wāhanga i runga ake i te uma (i runga ake i te diaphragm) (hei tauira, te upoko, te kaki, me ngā ringa), hoki atu ki te ngākau. Koinei te uaua tuarua nui rawa atu o tō tātou tinana.
2. Te Vena Cava o raro (IVC): Koinei te uaua nui rawa atu o tō tātou tinana. Ka haria e ia te toto rawakore-hāora mai i ngā wāhanga o raro o tō tātou tinana, arā, mai i ngā wāhanga i raro i te uma (i raro i te diaphragm) (hei tauira, ngā waewae, ngā whekau puku) ki te ngākau.
Whakaarohia he ara pahi. Ko ngā uaua iti e puta mai ana i ngā wāhanga o raro o ō tātou tinana (pērā i ngā whatukuhu, te ate, me te whēkau) he rite ki ngā pahi i te raina taone nui. Ko ngā toto kore-hāora katoa mai i ēnei pahi ka honoa ki roto i tētahi pahi nui e kiia nei ko te vena cava o raro (IVC) . Ko taua pahi te mea e kawe ana i tēnei toto ki te ngākau.
Waihoki, ko ngā uaua e puta mai ana i ngā wāhanga o runga o tō tātou tinana (hei tauira, te uma o runga, te tuara o runga) he rite ki ngā pahi i runga i te Uptown Line. Ko te toto kore-hāora e puta mai ana i ēnei pahi ka hono atu ki tētahi pahi nui e kiia nei ko te Superior Vena Cava (SVC) . Ka haere hoki tēnā ki te ngākau. Ko te ngākau te pokapū matua, te wāhi rānei e hono atu ai te toto kore-hāora e puta mai ana i ēnei rārangi katoa, i te tāone nui me te uptown. Kei te mārama koe?
He aha tonu te mea ka tupu ki te Vena Cava?
Ko te mahi nui rawa atu a te vena cava o runga (SVC) me te vena cava o raro (IVC) ko te kawe i te toto kore-hāora ki te atrium matau o te ngākau. Mai i reira, ka haere taua toto ki te ventricle matau o te ngākau. Kātahi, mai i te ventricle matau, ka tukuna tēnei toto ki ngā pukahukahu mā te uaua pūkahukahu .
Ko ngā pūkahukahu te wāhi e tangohia ai te hauhā waro i roto i te toto, ā, ka tāpirihia he hāora hou ki te toto. He rite ki te whakahou i te toto. Kātahi ka whakahokia te toto hou kua whai hāora ki te atrium maui o te ngākau mā roto i ngā uaua pūkahukahu .Mai i reira, ka haere te toto ki te ventricle maui , ā, mai i reira, ka tohatohahia puta noa i te tinana mā te aorta . Tirohia te uaua, engari te pai o te whakaritenga o te pūnaha!
Kei hea te Vena Cava?
Kei te taha matau o te ngākau ēnei uaua nui e rua, te vena cava o raro (IVC) me te vena cava o runga (SVC).
Ka honoa ō tātou uaua matau me ō tātou uaua maui (e kiia ana ko ngā uaua brachiocephalic ) hei hanga i te vena cava superior (SVC) . Kei te taha matau o te sternum tēnei SVC, te wheua i waenganui o te uma. Ka hono tika ki te atrium matau o te ngākau.
He roa ake te uaua o raro o te ngākau (VTI) . Ka tīmata i roto i te puku, te wāhi e hono ai ngā uaua iliac matau me maui. Mai i reira, ka piki ki te atrium matau o te ngākau.
He aha te āhua o te Vena Cava? He pēhea te rahi?
Ko te vena cava teitei (SVC) he uaua nui kāore he takirere i roto.
He uaua nui, he roa hoki te uaua cava o raro (IVC) , engari kotahi te takirere e hono ana ki te atrium matau o te ngākau.
Koinei ngā uaua nui rawa atu o tō tātou tinana.
- Ko te vena cava o runga (SVC) e 7 henimita (tata ki te 3 inihi) te roa, ā, e 2 henimita (iti iho i te inihi) te whānui.
- Ko te uaua cava o raro (IVC) e tata ana ki te 100 mirimita (tata ki te 4 inihi) te roa, ā, e tata ana ki te 22 mirimita (tata ki te inihi) te whānui.
He aha te mea i hangaia ai ēnei?
Ko te nuinga o ngā mea e titoa ana i roto i te vena cava o runga (SVC) me te vena cava o raro (IVC) ko:
- Ngā pūtau endothelial: Ka āwhina ēnei ki te whakawhiti matūkai me ngā kiko.
- Te kiko hono: Ka tautoko ēnei i ngā uaua.
- Ngā muka io.
- Ngā muka pīwariwari: Koinei ngā mea e homai ana ki ngā uaua te āhua totoro.
- Te kiko uaua.
He aha ngā āhuatanga noa e pā ana ki te Vena Cava?
I ētahi wā, ka āraihia te vena cava o runga (SVC) me te vena cava o raro (IVC). Ka whakararuraru tēnei i te rere o te toto. Ka kiia tēnei āhuatanga ko te Superior Vena Cava Syndrome , ko te Inferior Vena Cava Syndrome rānei, i runga i te wāhanga kua āraihia.
He maha ngā take matua mō ēnei aukati:
- He pukupuku: hei tauiraKa taea e te mate pukupuku pūkahukahu , e tētahi atu momo mate pukupuku rānei, te horapa me te pēhi i ēnei uaua.
- Ngā totoka: I ētahi wā ka puta he totoka i roto i te vena cava teitei i roto i te hunga whai catheter uaua pokapū , pacemaker rānei.
- Te āhua whānau kore: Ko te tikanga o tēnei he mea kāore i te tika te hanganga i roto tonu i te kōpū.
He aha ngā tohu o te raruraru o te Vena Cava?
Ina pēhia te vena cava o runga (SVC) me te vena cava o raro (IVC) e tetahi mea, ina āraia rānei te rere o te toto mai i roto, ka puta ngā tohu pēnei i:
Ngā Tohu o te Mate Puku o te Upoko o te Vena Cava (ārai, pēhi rānei):
- Te pupuhi o te tinana o runga (te mata, te kaki, ngā ringa).
- Te poto o te manawa.
- Angina ( mamae o te uma).
Ngā tohu i puta mai i te toto totoka, i te pukupuku rānei i roto i te vena cava teitei (SVC):
- Te pupuhi i te tinana o runga.
- Te poto o te manawa.
Ngā tohu o te toto totoka i roto i te vena cava o raro (IVC):
- Te pupuhi o ngā waewae.
- Mamae tuara.
- Te pikinga o te taumaha.
- Te mamae nui o ngā waewae.
Ngā tohu i puta mai i te pukupuku i roto i te vena cava o raro (IVC):
- Mamae puku.
- Te pupuhi o ngā waewae.
- Te whakahekenga taumaha.
Ngā Tohu o te Inferior Vena Cava Syndrome (ārai, pēhi rānei):
- Te toto toto iti.
- Te pupuhi i te tinana o raro.
- Tachycardia (tere o te ngakau).
He mea nui: Ki te pā mai tētahi, ētahi rānei o ēnei tohu, me toro atu ki te tākuta tonu. He tohu anō hoki ēnei nō ētahi atu mate, nō reira he mea nui kia kitea te āhua o te mate.
He aha ngā whakamātautau e mahia ana hei tirotiro i te hauora o te Vena Cava?
He maha ngā whakamātautau a tō tākuta hei tirotiro i te āhua o te Vena Cava. Ko ētahi o ēnei ko:
- He hihi-X o te uma (ka whakamahia tēnei hei tirotiro i te vena cava o runga).
- Te angiography coronary (ka taea hoki te tirotiro i te vena cava o runga).
- Whakamātautau ultrasound.
- Whakamātautau Matawai CT (CT - Tomography Rorohiko).
- Whakamātautau matawai MRI (MRI - Magnetic Resonance Imaging).
- Te venography rerekē, te phlebography rānei (he hihi-X tēnei o ngā uaua, engari kāore e whakamahia nuitia ana i ēnei rā).
He aha ngā rongoā mō ngā raruraru e pā ana ki te Vena Cava?
Mēnā kei te rongoatia te raruraru o te vena cava o runga (SVC) me te vena cava o raro (IVC), ka whakamahia pinepinetia ngā tikanga maimoatanga ōrite.
- Hei rongoā i te pupuhi, ka taea te hoatu i ngā diuretics ( ngā rongoā hei whakanui ake i te putanga mimi) me ngā steroids rānei.
- Ka taea te hoatu i ngā steroids , ngā thrombolytics (ngā rongoā whakarewa toto toto), me ngā anticoagulants (ngā rongoā ārai toto toto) hei rongoā i ngā aukati pēnei i te toto totoka.
- Ka taea te tango i te toto totoka mā te whakamahi i te catheter .
- Mena ka whaiti te uaua (stenosis) nā te toto totoka, ka taea te mahi angioplasty (te pēhi i te aukati ki te pakitara o te uaua) ā, ka taea te whakauru i tētahi stent ( he ngongo whakarewa iti).
- Mena he toto totoka, he pukupuku rānei , ka taea te mahi pokanga bypass .
- Mena he pukupuku kei reira, ka taea te tango ma te pokanga.
- Ka taea te hoatu i te chemotherapy , te radiation therapy rānei hei rongoā i ngā pukupuku.
