Emikutu emikulu ebiri egireeta omusaayi ku mutima gwaffe: Byonna bikwata ku Vena Cava!

Wali weebuuzizzaako engeri omusaayi mu mubiri gwaffe gye gutuuka ku mutima ate ne gudda mu mubiri gwonna? Enkola eyeewuunyisa. Leero tugenda kwogera ku kika ekikulu ennyo eky’omusuwa omunene oguyamba ku mulimu guno. Kiyitibwa Vena Cava . Oboolyawo wali okiwulirako emabegako. Ka tulabe kiki kye kiri, kiki kye kikola, n’ebizibu bye kiyinza okuleeta.

Vena Cava kye ki?

Mu ngeri ennyangu, Vena Cava misuwa ebiri eminene ennyo mu mubiri gwaffe. Zikung’aanya omusaayi ogukozesebwa, ogutaliimu mukka gwa oxygen okuva mu bitundu by’omubiri gwaffe eby’enjawulo ne guzza ku ludda olwa ddyo olw’omutima. Kilowoozeeko ng’emisuwa emikulu ebiri egizza omusaayi ogwakozesebwa mu mutima okuyonjebwa.

Vena Cava alina ebika bibiri:

1. Superior Vena Cava (SVC): Kino kitwala omusaayi ogutaliimu mukka gwa oxygen okuva mu kitundu eky’okungulu eky’omubiri gwaffe, kwe kugamba, okuva mu bitundu ebiri waggulu w’ekifuba (waggulu w’ekifuba) (okugeza, omutwe, ensingo, n’emikono), okudda ku mutima. Guno gwe musuwa ogw’okubiri mu bunene mu mubiri gwaffe.

2. Inferior Vena Cava (IVC): Guno gwe musuwa ogusinga obunene mu mubiri gwaffe. Kitambuza omusaayi ogutaliimu mukka gwa oxygen okuva mu bitundu by’omubiri gwaffe ebya wansi, kwe kugamba, okuva mu bitundu ebiri wansi w’ekifuba (wansi w’ekifuba) (okugeza amagulu, ebitundu by’olubuto) okutuuka ku mutima.

Kilowoozeeko ng’ekkubo lya bbaasi. Emisuwa emitono egiva mu bitundu by’omubiri gwaffe ebya wansi (nga ensigo, ekibumba, n’ennywanto) bulinga bbaasi eziri ku layini y’omu kibuga wakati. Omusaayi gwonna ogutaliimu mukka gwa oxygen oguva mu bbaasi zino gwegatta wamu mu bbaasi ennene eyitibwa inferior vena cava (IVC) . Bbaasi eyo y’etwala omusaayi guno okutuuka ku mutima.

Ate era, emisuwa egiva mu bitundu by’omubiri gwaffe ebya waggulu (e.g., ekifuba ekya waggulu, omugongo ogwa waggulu) giringa bbaasi eziri ku Uptown Line. Omusaayi ogutaliimu mukka oguva mu bbaasi zino gwegatta ku bbaasi ennene eyitibwa Superior Vena Cava (SVC) . Ekyo nakyo kigenda ku mutima. Omutima gwe kifo ekikulu oba ekifo we bagenda, omusaayi ogutaliimu mukka oguva mu layini zino zonna, wakati mu kibuga ne waggulu, we gwegatta. Otegedde?

Kiki ddala ekituuka ku Vena Cava?

Omulimu ogusinga obukulu ogw’omusuwa ogw’okungulu (SVC) n’omusuwa ogwa wansi (IVC) kwe kutwala omusaayi ogutaliimu mukka gwa oxygen okutuuka mu kitundu kya ddyo eky’omutima gwaffe. Okuva awo, omusaayi ogwo gugenda mu kisenge kya ddyo eky’omutima. Oluvannyuma, okuva mu kisenge kya ddyo, omusaayi guno gusindikibwa mu mawuggwe nga guyita mu musuwa gw’amawuggwe .

Amawuggwe we gaggyibwamu kaboni dayokisayidi ali mu musaayi n’ateekebwa mu musaayi omukka omupya. Kiringa okuzza obuggya omusaayi. Olwo omusaayi omupya ogulimu omukka gwa oxygen guddizibwa mu kitundu kya kkono eky'omutima nga guyita mu misuwa gy'amawuggwe .Okuva awo, omusaayi gugenda mu kisenge kya kkono , era okuva awo, ne gusaasaanyizibwa mu mubiri gwonna nga guyita mu aorta . Laba engeri enkola eno gy’ezibu ennyo, naye ng’etegekeddwa bulungi!

Vena Cava esangibwa wa?

Emisuwa gino eminene ebiri, omusuwa ogwa wansi (IVC) n’omusuwa ogw’okungulu (SVC), gwombi gusangibwa ku ludda olwa ddyo olw’omutima gwaffe .

Emisuwa gyaffe egya ddyo n’egya kkono egitamanyiddwa (era giyitibwa brachiocephalic veins ) gyegatta ne gikola emisuwa egy’oku ntikko (SVC) . SVC eno esangibwa ku ddyo w’omugongo , eggumba eriri wakati mu kifuba kyaffe. Kiyungibwa butereevu ku kitundu kya ddyo eky’omutima.

Omusuwa oguyitibwa inferior vena cava (IVC) guwanvuwa katono. Kitandikira mu lubuto lwaffe, emisuwa egy’awamu egya ddyo ne kkono gye gigatta. Okuva awo, kitambula okutuuka mu kisenge kya ddyo eky’omutima.

Vena Cava eringa etya? Kiba kinene kitya?

Omusuwa oguyitibwa superior vena cava (SVC) musuwa munene ogutalina vvaalu munda mu gwo.

Omusuwa ogwa wansi (IVC) nagwo musuwa munene era muwanvu, naye gulina vvaalu emu gye gukwatagana n’omusuwa ogwa ddyo ogw’omutima.

Zino ze misuwa egisinga obunene mu mubiri gwaffe.

• Omusuwa oguyitibwa superior vena cava (SVC) guweza sentimita nga 7 (kumpi yinsi 3) n’obugazi bwa sentimita nga 2 (obutakka wansi wa yinsi emu).
• Omusuwa ogwa wansi (IVC) guweza milimita nga 100 (yinsi nga 4) ate mu buwanvu bwa milimita nga 22 (kumpi yinsi emu).

Bino bikolebwa mu ki?

Omusuwa ogw’okungulu (SVC) n’omusuwa ogwa wansi (IVC) okusinga bikolebwa:

• Obutoffaali obuyitibwa endothelial cells: Buno buyamba okuwanyisiganya ebiriisa n’ebitundu by’omubiri.
• Ebitundu ebiyunga: Bino biwa obuwagizi eri emisuwa.
• Ebiwuzi by’obusimu.
• Ebiwuzi ebiwanvuwa: Bino bye biwa emisuwa obutonde bwagwo obw’okugolola.
• Ebinywa ebikola ebitundu by’omubiri.

Embeera ki ezitera okukwata ku Vena Cava?

Oluusi, wayinza okubaawo okuzibikira mu misuwa egy’okungulu (SVC) oba mu misuwa egy’okunsi (IVC). Kino kitaataaganya okutambula kw’omusaayi. Embeera eno eyitibwa Superior Vena Cava Syndrome oba Inferior Vena Cava Syndrome , okusinziira ku kitundu ki ekizibiddwa.

Waliwo ensonga enkulu eziwerako eziviirako okuzibikira kuno:

• Ekizimba: okugezaKookolo w’amawuggwe , oba kookolo ow’ekika ekirala, asobola okusaasaana n’okunyigiriza emisuwa gino.
• Okuzimba omusaayi: Oluusi okuzimba omusaayi kuyinza okutondebwa mu misuwa egy’okungulu mu bantu abalina emisuwa egy’omu makkati oba ebyuma ebikuba omukka .
• Congenital malformation: Kino kitegeeza ekintu ekitakola bulungi nga kikyali mu lubuto.

Bubonero ki obulaga obuzibu ku Vena Cava?

Omusuwa ogw’okungulu (SVC) oba omusuwa ogwa wansi (IVC) bwe gunyigirizibwa ekintu, oba omusaayi bwe guzibiddwa okuva munda, obubonero nga:

Superior Vena Cava Syndrome (okuzibikira oba okunyigirizibwa) Obubonero:

• Okuzimba kw’omubiri ogwa waggulu (ffeesi, ensingo, emikono).
• Okussa obubi.
• Angina ( okulumwa mu kifuba).

Obubonero obuva ku kuzimba omusaayi oba ekizimba mu misuwa egy’oku ntikko (SVC):

• Okuzimba mu mubiri ogwa waggulu.
• Okussa obubi.

Obubonero bw’okuzimba omusaayi mu misuwa egya wansi (IVC):

• Okuzimba kw’amagulu.
• Obulumi bw’omugongo.
• Okweyongera kw’omugejjo.
• Obulumi obw’amaanyi mu magulu.

Obubonero obuva ku kizimba mu misuwa egya wansi (IVC):

• Obulumi mu lubuto.
• Okuzimba kw’amagulu.
• Okugejja.

Obubonero bw’obulwadde bwa Inferior Vena Cava Syndrome (okuzibikira oba okunyigirizibwa):

• Puleesa ekka.
• Okuzimba mu mubiri ogwa wansi.
• Tachycardia (omutima okukuba amangu).

Ekikulu: Bw’oba ​​olina ekimu oba ebisingawo ku bubonero buno, laba omusawo mu bwangu. Bino era biyinza okuba obubonero bw’endwadde endala, n’olwekyo kikulu okumanya ddala ekikyamu.

Bikebere ki ebikolebwa okukebera obulamu bwa Vena Cava?

Omusawo wo alina okukeberebwa okuwerako okukebera embeera ya Vena Cava. Ebimu ku byo mulimu:

• X-ray y’ekifuba (kino kikozesebwa okutunuulira omusuwa ogw’okungulu).
• Coronary angiography (kino era kiyinza okutunuulira omusuwa ogw’okungulu).
• Okukeberebwa mu ngeri ya Ultrasound.
• Okugezesebwa kwa CT Scan (CT - Computed Tomography).
• Okukebera mu ngeri ya MRI scan (MRI - Magnetic Resonance Imaging).
• Contrast venography oba phlebography (kino X-ray y’emisuwa, naye tekikyakozesebwa nnyo).

Bujjanjabi ki obw’ebizibu ebikwata ku Vena Cava?

Nga ojjanjaba ekizibu oba omusuwa ogw’okungulu (SVC) oba ogw’omusuwa ogwa wansi (IVC), enkola z’obujjanjabi ezifaananako bwe zityo zitera okukozesebwa.

• Diuretics ( eddagala eryongeza omusulo) oba steroids ziyinza okuweebwa okujjanjaba okuzimba.
• Steroids , thrombolytics (eddagala erisaanuusa omusaayi okuzimba), n’eddagala eriziyiza okuzimba omusaayi (eddagala eriziyiza okuzimba omusaayi) biyinza okuweebwa okujjanjaba ebizibikira ng’okuzimba omusaayi.
• Omusaayi oguzimba osobola okuguggyamu ng'okozesa ekituli .
• Singa omusuwa gufunda (stenosis) olw’omusaayi okuzimba, angioplasty (okunyiga ekizibikira ku bbugwe w’omusuwa) kuyinza okukolebwa ne stent ( akatundu akatono ak’ekyuma) kuyinza okuteekebwamu.
• Singa wabaawo omusaayi oguzimba oba ekizimba , basobola okulongoosebwa nga bayita mu ngeri ya bypass .
• Singa wabaawo ekizimba, osobola okukiggyamu ng’olongooseddwa.
• Chemotherapy oba radiation therapy esobola okuweebwa okujjanjaba ebizimba.

Ate era, bw’oba ​​olina obulwadde bwa Deep Vein Thrombosis (DVT) (embeera omusaayi mwe gukola okuzimba mu magulu) era ng’oli mu bulabe bw’okuzimba omusaayi okuva ku magulu oba mu kisambi okutuuka mu mawuggwe (ekiyitibwa pulmonary embolism (PE) , omusawo wo ayinza okusalawo okussaamu ekyuma ekisengejja omusaayi ekya Vena Cava . Omusengejja guno gutega ebizimba omusaayi ne guziyiza okugenda mu mawuggwe.

Oyinza otya okukuuma Vena Cava yo nga nnungi?

Okufaananako n’emisuwa emirala mu mubiri gwo, osobola okulabirira Vena Cava eno.

• Lya emmere ennungi erimu amasavu amatono.
• Dduyiro buli kiseera.
• Kendeeza ku situleesi.
• Fuga embeera nga puleesa , kolesterol omungi, ne sukaali .

N’ekisembayo, ekisinga obukulu

Bw’oba ​​olina ekizibiti mu misuwa egy’oku ntikko (SVC) oba mu misuwa egy’okunsi (IVC), omusawo wo alina engeri eziwerako gy’ayinza okugijjanjaba. Yogera naye ku bujjanjabi obusinga obulungi ku mbeera yo. Omusawo bw’aba akuwadde eddagala, limira ddala nga bwe yakulagidde. Bw’oba ​​olongooseddwa oba obujjanjabi obulala, kakasa nti okuuma essaawa z’omusawo okutuusa lw’oteredde mu bujjuvu. Obulamu bwo buli mu mikono gyo!
