Njira ziwiri zazikulu zomwe zimadzetsa magazi mumtima mwathu: Zonse zokhudza Vena Cava!

Kodi munayamba mwadzifunsapo momwe magazi m'thupi lathu amafikira pamtima kenako n'kubwerera ku thupi lonse? Ndi njira yodabwitsa. Lero tikambirana za mtundu wofunika kwambiri wa mtsempha waukulu womwe umathandiza pa ntchitoyi. Umatchedwa Vena Cava . Mwina munamvapo kale za izi. Tiyeni tiwone zomwe zili, zomwe zimagwira ntchito, komanso mavuto omwe angayambitse.

Kodi Vena Cava ndi chiyani?

Mwachidule, Vena Cava ndi mitsempha ikuluikulu iwiri m'thupi lathu. Imasonkhanitsa magazi ogwiritsidwa ntchito, opanda mpweya kuchokera m'zigawo zosiyanasiyana za thupi lathu ndikubwezeretsa kumbali yakumanja ya mtima. Taganizirani ngati mitsempha ikuluikulu iwiri yomwe imabwezeretsa magazi ogwiritsidwa ntchito kumtima kuti ayeretsedwe.

Pali mitundu iwiri ya Vena Cava:

1. Superior Vena Cava (SVC): Iyi imanyamula magazi opanda mpweya kuchokera kumtunda kwa thupi lathu, kutanthauza, kuchokera ku ziwalo zomwe zili pamwamba pa chifuwa (pamwamba pa diaphragm) (monga mutu, khosi, ndi manja), kubwerera kumtima. Iyi ndi mtsempha wachiwiri waukulu m'thupi lathu.

2. Vena Cava Wosauka (IVC): Uwu ndi mtsempha waukulu kwambiri m'thupi lathu. Umanyamula magazi opanda mpweya kuchokera m'zigawo zapansi pa thupi lathu, kutanthauza, kuchokera m'zigawo zomwe zili pansi pa chifuwa (pansi pa diaphragm) (monga miyendo, ziwalo zam'mimba) kupita kumtima.

Taganizirani izi ngati njira ya basi. Mitsempha yaying'ono yomwe imachokera m'magawo otsika a matupi athu (monga impso, chiwindi, ndi ndulu) ili ngati mabasi omwe ali pamzere wapakati pa mzinda. Magazi onse opanda mpweya ochokera m'mabasi awa amalumikizana pamodzi mu basi yayikulu yotchedwa inferior vena cava (IVC) . Basi imeneyo ndiyo imanyamula magazi awa kupita kumtima.

Komanso, mitsempha yomwe imachokera kumtunda kwa thupi lathu (monga chifuwa chapamwamba, kumbuyo chakumtunda) ili ngati mabasi a Uptown Line. Magazi ochotsedwa mpweya ochokera m'mabasi awa amalumikizana ndi basi yayikulu yotchedwa Superior Vena Cava (SVC) . Imeneyo imapitanso kumtima. Mtima ndiye malo ofunikira, kapena komwe umapita, komwe magazi ochotsedwa mpweya ochokera m'mizere yonseyi, pakati pa mzinda ndi m'tawuni, amalumikizana. Kodi mukumvetsa?

Kodi n’chiyani kwenikweni chomwe chimachitika ndi Vena Cava?

Ntchito yofunika kwambiri ya superior vena cava (SVC) ndi inferior vena cava (IVC) ndikunyamula magazi osowa mpweya kupita nawo ku atrium yakumanja ya mtima wathu. Kuchokera pamenepo, magazi amenewo amapita ku ventricle yakumanja ya mtima. Kenako, kuchokera ku ventricle yakumanja, magazi awa amatumizidwa ku mapapo kudzera mu mtsempha wa m'mapapo .

Mapapu ndi komwe mpweya wa carbon dioxide m'magazi umachotsedwa ndipo mpweya watsopano umawonjezeredwa m'magazi. Zili ngati kukonzanso magazi. Magazi atsopano okhala ndi mpweya amabwezeretsedwa ku atrium yakumanzere ya mtima kudzera m'mitsempha ya m'mapapo .Kuchokera pamenepo, magazi amapita ku ventricle yakumanzere , ndipo kuchokera pamenepo, amafalikira m'thupi lonse kudzera mu aorta . Taonani momwe dongosololi lilili lovuta, koma lokonzedwa bwino!

Kodi Vena Cava ili kuti?

Mitsempha ikuluikulu iwiri iyi, inferior vena cava (IVC) ndi superior vena cava (SVC), yonse ili kumanja kwa mtima wathu .

Mitsempha yathu ya kumanja ndi kumanzere (yomwe imatchedwanso mitsempha ya brachiocephalic ) imalumikizana kuti ipange vena cava yapamwamba (SVC) . SVC iyi ili kumanja kwa sternum , fupa lomwe lili pakati pa chifuwa chathu. Imalumikizana mwachindunji ndi atrium yakumanja ya mtima.

Vena cava ya m'munsi (IVC) ndi yayitali pang'ono. Imayambira m'mimba mwathu, komwe mitsempha ya m'mimba yamanja ndi yamanzere imalumikizana. Kuchokera pamenepo, imapita ku atrium yakumanja ya mtima.

Kodi Vena Cava imawoneka bwanji? Ndi yaikulu bwanji?

Vena cava yapamwamba (SVC) ndi mtsempha waukulu womwe ulibe ma valve mkati mwake.

Vena cava ya m'munsi (IVC) nayonso ndi mtsempha waukulu, wautali, koma ili ndi valavu imodzi yomwe imalumikizana ndi atrium yakumanja ya mtima.

Iyi ndi mitsempha ikuluikulu m'thupi lathu.

• Vena cava yapamwamba (SVC) ndi yayitali pafupifupi masentimita 7 (pafupifupi mainchesi 3) ndipo mulifupi mwake ndi pafupifupi masentimita awiri (osakwana inchi imodzi).
• Vena cava ya m'munsi (IVC) ndi yayitali pafupifupi mamilimita 100 (pafupifupi mainchesi 4) ndipo m'mimba mwake pafupifupi mamilimita 22 (pafupifupi inchi imodzi).

Kodi izi zimapangidwa ndi chiyani?

Vena cava yapamwamba (SVC) ndi vena cava yapansi (IVC) zimapangidwa makamaka ndi:

• Maselo a Endothelial: Izi zimathandiza kusinthana zakudya ndi minofu.
• Minofu yolumikizana: Izi zimathandiza mitsempha.
• Ulusi wa mitsempha.
• Ulusi wotanuka: Izi ndi zomwe zimapangitsa kuti mitsempha ikhale yotambasuka.
• Minofu ya minofu.

Kodi ndi matenda ati omwe amakhudza Vena Cava?

Nthawi zina, pakhoza kukhala kutsekeka kwa vena cava yapamwamba (SVC) kapena inferior vena cava (IVC). Izi zimasokoneza kuyenda kwa magazi. Matendawa amatchedwa Superior Vena Cava Syndrome kapena Inferior Vena Cava Syndrome , kutengera gawo lomwe latsekeka.

Pali zifukwa zingapo zazikulu zomwe zimapangitsa kuti izi zilephereke:

• Chotupa: mwachitsanzoKhansa ya m'mapapo , kapena mtundu wina wa khansa, imatha kufalikira ndikufinya mitsempha iyi.
• Magazi amaundana: Nthawi zina magazi amaundana mu vena cava yapamwamba mwa anthu omwe ali ndi ma catheter apakati a mitsempha kapena ma pacemaker .
• Kusabereka bwino: Izi zikutanthauza chinthu chomwe sichimapangidwa bwino chikadali m'mimba.

Kodi zizindikiro za vuto la Vena Cava ndi ziti?

Pamene vena cava yapamwamba (SVC) kapena inferior vena cava (IVC) yapanikizika ndi china chake, kapena pamene magazi atsekedwa mkati, zizindikiro monga:

Zizindikiro za Superior Vena Cava Syndrome (kutsekeka kapena kupsinjika):

• Kutupa kwa thupi lapamwamba (nkhope, khosi, manja).
• Kupuma movutikira.
• Angina ( kupweteka pachifuwa).

Zizindikiro zomwe zimayambitsidwa ndi magazi kuundana kapena chotupa mu vena cava yapamwamba (SVC):

• Kutupa m'thupi lapamwamba.
• Kupuma movutikira.

Zizindikiro za magazi kuundana mu inferior vena cava (IVC):

• Kutupa kwa miyendo.
• Kupweteka kwa msana.
• Kulemera.
• Kupweteka kwambiri m'miyendo.

Zizindikiro zomwe zimayambitsidwa ndi chotupa mu inferior vena cava (IVC):

• Kupweteka m'mimba.
• Kutupa kwa miyendo.
• Kuchepetsa thupi.

Zizindikiro za Inferior Vena Cava Syndrome (kutsekeka kapena kupsinjika):

• Kuthamanga kwa magazi pang'ono.
• Kutupa m'thupi la pansi.
• Tachycardia (kugunda kwa mtima mwachangu).

Chofunika: Ngati muli ndi chimodzi mwa zizindikiro izi, pitani kwa dokotala nthawi yomweyo. Izi zitha kukhalanso zizindikiro za matenda ena, choncho ndikofunikira kudziwa chomwe chikuvuta.

Ndi mayeso ati omwe amachitidwa kuti aone ngati Vena Cava ili bwino?

Dokotala wanu ali ndi mayeso angapo kuti awone momwe Vena Cava ilili. Ena mwa iwo ndi awa:

• X-ray ya pachifuwa (izi zimagwiritsidwa ntchito poyang'ana vena cava yapamwamba).
• Coronary angiography (izi zitha kuyang'ananso vena cava yapamwamba).
• Kufufuza kwa Ultrasound.
• Mayeso a CT Scan (CT - Computed Tomography).
• Kuyesa kwa MRI (MRI - Magnetic Resonance Imaging).
• Kusiyanitsa kwa venography kapena phlebography (iyi ndi X-ray ya mitsempha, koma sikugwiritsidwanso ntchito kwambiri).

Kodi ndi mankhwala otani a mavuto okhudzana ndi Vena Cava?

Pochiza vuto ndi superior vena cava (SVC) kapena inferior vena cava (IVC), njira zofanana zochiritsira zimagwiritsidwa ntchito nthawi zambiri.

• Mankhwala ochepetsa kutupa ( mankhwala omwe amawonjezera kutulutsa kwa mkodzo) kapena ma steroids angaperekedwe pochiza kutupa.
• Mankhwala otchedwa steroids , thrombolytics (mankhwala osungunula magazi), ndi mankhwala oletsa magazi kuundana (mankhwala oletsa magazi kuundana) angaperekedwe pochiza kutsekeka monga magazi kuundana.
• Magazi oundana amatha kuchotsedwa pogwiritsa ntchito catheter .
• Ngati mtsempha wa magazi wachepa (stenosis) chifukwa cha magazi kuundana, angioplasty (kukanikiza khoma la mtsempha) ikhoza kuchitidwa ndipo stent ( chubu chaching'ono chachitsulo) ikhoza kuyikidwa.
• Ngati magazi atuluka kapena chotupa , opaleshoni ya bypass ikhoza kuchitidwa.
• Ngati pali chotupa, chingachotsedwe mwa opaleshoni.
• Mankhwala a chemotherapy kapena radiation angaperekedwe pochiza zotupa.

Komanso, ngati muli ndi Deep Vein Thrombosis (DVT) (vuto lomwe magazi amaundana m'miyendo) ndipo muli pachiwopsezo cha magazi kuundana kuchokera m'miyendo kapena m'chiuno kupita m'mapapo (lotchedwa pulmonary embolism (PE) , dokotala wanu angasankhe kuyika fyuluta ya Vena Cava . Fyuluta iyi imasunga magazi kuundana ndi kuwaletsa kupita m'mapapo.

Kodi mungatani kuti Vena Cava yanu ikhale yathanzi?

Monga mitsempha ina yamagazi m'thupi lanu, mutha kusamalira Vena Cava iyi.

• Idyani zakudya zabwino zokhala ndi mafuta ochepa.
• Kuchita masewera olimbitsa thupi nthawi zonse.
• Chepetsani kupsinjika maganizo.
• Lamulirani matenda monga kuthamanga kwa magazi , cholesterol yambiri, ndi matenda a shuga .

Pomaliza, chinthu chofunika kwambiri

Ngati muli ndi vuto la vena cava yapamwamba (SVC) kapena inferior vena cava (IVC), dokotala wanu ali ndi njira zingapo zochizira. Kambiranani naye za chithandizo chabwino kwambiri cha matenda anu. Ngati dokotala wanu akulemberani mankhwala, imwani monga momwe mwalangizidwira. Ngati mwachitidwa opaleshoni kapena chithandizo china, onetsetsani kuti mwasunga nthawi yokumana ndi dokotala wanu mpaka mutachira bwino. Thanzi lanu lili m'manja mwanu!
