Imiyoboro ibiri y'ingenzi izana amaraso mu mitima yacu: Byose kuri Vena Cava!

Ese wigeze wibaza uburyo amaraso ari mu mubiri wacu agera mu mutima hanyuma akagaruka mu wundi mubiri? Ni igikorwa gitangaje. Uyu munsi tugiye kuvuga ku bwoko bw'ingenzi cyane bw'imitsi minini ifasha muri uyu murimo. Yitwa Vena Cava . Ushobora kuba warigeze kubyumva mbere. Reka turebe icyo ari cyo, icyo bikora, n'ibibazo bishobora gutera.

Vena Cava ni iki?

Mu magambo make, Vena Cava ni imitsi ibiri minini cyane mu mubiri wacu. Ikusanya amaraso yakoreshejwe, yakuwe mu bice bitandukanye by'umubiri wacu, ikayagarura iburyo bw'umutima. Tekereza nk'imitsi ibiri y'ingenzi igarura amaraso yakoreshejwe mu mutima kugira ngo yozwe.

Hari ubwoko bubiri bwa Vena Cava:

1. Superior Vena Cava (SVC): Iyi itwara amaraso adahumeka neza mu gice cyo hejuru cy'umubiri wacu, ni ukuvuga mu bice biri hejuru y'igituza (hejuru ya diaphragm) (urugero, umutwe, ijosi, n'amaboko), ikayasubiza mu mutima. Uyu ni wo mutsi wa kabiri mu bunini mu mubiri wacu.

2. Vena Cava yo hasi (IVC): Uyu ni wo mutsi munini mu mubiri wacu. Utwara amaraso adahumeka neza mu bice byo hasi by'umubiri wacu, ni ukuvuga mu bice biri munsi y'igituza (munsi ya diaphragm) (urugero, amaguru, ingingo zo mu nda) ukayajyana mu mutima.

Tekereza nk'inzira ya bisi. Imitsi mito ituruka mu bice byo hasi by'umubiri wacu (nk'impyiko, umwijima, n'udusimba) ni nk'amabisi ari ku murongo wo hagati mu mujyi. Amaraso yose yakuwe muri izi bisi ahurira hamwe muri bisi nini yitwa inferior vena cava (IVC) . Iyo bisi ni yo itwara aya maraso mu mutima.

Nanone, imitsi ituruka mu bice byo hejuru by'umubiri wacu (urugero, igituza cyo hejuru, umugongo wo hejuru) ni nk'amabisi ari ku murongo wa Uptown. Amaraso yakuwe muri izi bisi ahurira na bisi nini yitwa Superior Vena Cava (SVC) . Ibyo kandi bijya mu mutima. Umutima ni wo gice nyamukuru, cyangwa aho amaraso yakuwe muri izi nzira zose, mu mujyi rwagati no mu mujyi rwagati, ahurira. Urabyumva?

Ni iki gihinduka kuri Vena Cava?

Inshingano y'ingenzi ya vena cava (SVC) na vena cava y'inyongera (IVC) ni ugutwara amaraso yabuze umwuka wa ogisijeni mu gituza cy'iburyo cy'umutima wacu. Kuva aho, ayo maraso ajya mu gituza cy'iburyo cy'umutima. Hanyuma, ava mu gituza cy'iburyo, ayo maraso yoherezwa mu bihaha binyuze mu mitsi y'ibihaha .

Mu bihaha niho hakurwa umwuka wa karuboni mu maraso hanyuma umwuka mushya wongerwa mu maraso. Ni nko kuvugurura amaraso. Amaraso mashya arimo umwuka asubizwa mu gice cy'ibumoso cy'umutima binyuze mu mitsi y'ibihaha .Kuva aho, amaraso ajya muri ventricle y'ibumoso , hanyuma akava aho, agakwirakwira mu mubiri wose binyuze muri aorta . Reba ukuntu sisitemu igoye, ariko itunganijwe neza!

Vena Cava iherereye he?

Iyi mitsi ibiri minini, vena cava iri hasi (IVC) na vena cava iri hejuru (SVC), yombi iherereye iburyo bw'umutima wacu .

Imitsi yacu y'iburyo n'ibumoso ifatana (izwi kandi ko ari imitsi ya brachiocephalic ) ifatanya igakora vena cava nziza (SVC) . Iyi SVC iherereye iburyo bwa sternum , igufwa riri hagati mu gituza cyacu. Ihuza neza n'atriyumu y'iburyo y'umutima.

Vena cava yo hasi (IVC) ni ndende gato. Itangirira mu nda yacu, aho imitsi isanzwe y'iburyo n'ibumoso ya iliac ihurira. Kuva aho, izamuka ikagera ku gice cy'iburyo cy'umutima.

Vena Cava isa ite? Ingana iki?

Vena cava (SVC) ni umutsi munini udafite valves imbere muri wo.

Vena cava yo hasi (IVC) nayo ni umutsi muremure, ariko ifite valve imwe aho ihuzwa n'atriyumu y'iburyo y'umutima.

Iyi ni yo mitsi minini mu mubiri wacu.

• Vena cava (SVC) ifite uburebure bwa santimetero 7 (hafi santimetero 3) n'ubugari bwa santimetero 2 (munsi ya santimetero imwe).
• Vena cava yo hasi (IVC) ifite uburebure bwa milimetero 100 (hafi santimetero 4) n'umurambararo wa milimetero 22 (hafi santimetero imwe).

Ibi bikozwe mu ki?

Vena cava nziza (SVC) na vena cava yoroheje (IVC) bigizwe ahanini na:

• Uturemangingo tw’imbere mu mubiri: Ibi bifasha mu guhanahana intungamubiri n’uturemangingo.
• Imitsi ihuza: Iyi mitsi ishyigikira imitsi.
• Imitsi y'imitsi.
• Imitsi irashya: Iyi ni yo ituma imitsi irushaho kurambuka.
• Imitsi.

Ni izihe ndwara zikunze kwibasira Vena Cava?

Hari igihe hashobora kubaho imbogamizi muri vena cava (SVC) cyangwa inferior vena cava (IVC). Ibi bibangamira urujya n'uruza rw'amaraso. Iyi ndwara yitwa Superior Vena Cava Syndrome cyangwa Inferior Vena Cava Syndrome , bitewe n'igice cyayo cyafunzwe.

Hari impamvu nyinshi z'ingenzi zitera izi mbogamizi:

• Ikibyimba: urugeroKanseri y'ibihaha , cyangwa ubundi bwoko bwa kanseri, ishobora gukwirakwira no gukanda iyi mitsi.
• Amaraso apfundika: Hari igihe amaraso ashobora kupfundika muri vena cava nziza ku bantu bafite catheter zo hagati mu mitsi cyangwa pacemakers .
• Ubusembwa bw'impinja: Ibi bivuze ikintu kidakora neza mu gihe kikiri mu nda.

Ni ibihe bimenyetso by'ikibazo cya Vena Cava?

Iyo vena cava ihanitse (SVC) cyangwa vena cava ihanitse (IVC) ishyizwemo ikintu, cyangwa iyo amaraso afunze imbere, ibimenyetso nka:

Indwara ya Superior Vena Cava (kubangamira cyangwa gukanda) Ibimenyetso:

• Kubyimba igice cyo hejuru cy'umubiri (mu maso, mu ijosi, mu maboko).
• Guhumeka nabi.
• Angina ( kubabara mu gatuza).

Ibimenyetso biterwa no kubyimba kw'amaraso cyangwa ikibyimba muri vena cava nziza (SVC):

• Kubyimba mu gice cyo hejuru cy'umubiri.
• Guhumeka nabi.

Ibimenyetso by'uko amaraso yacitse mu gice cy'imbere cy'imitsi yo mu bwonko (IVC):

• Kubyimba amaguru.
• Kubabara umugongo.
• Kongera ibiro.
• Ububabare bukomeye mu maguru.

Ibimenyetso biterwa n'ikibyimba muri vena cava iri munsi y'imitsi (IVC):

• Kubabara mu gifu.
• Kubyimba amaguru.
• Kugabanya ibiro.

Ibimenyetso bya Inferior Vena Cava Syndrome (kwibasirwa cyangwa gukandamizwa):

• Umuvuduko w'amaraso uri hasi.
• Kubyimba mu gice cyo hasi cy'umubiri.
• Tachycardia (umutima utera vuba).

Icy'ingenzi: Niba ufite kimwe cyangwa byinshi muri ibi bimenyetso, jya kwa muganga vuba. Ibi bishobora no kuba ibimenyetso by'izindi ndwara, bityo rero ni ngombwa kumenya neza ikibazo kirimo.

Ni ibihe bizamini bikorerwa kugira ngo harebwe ubuzima bwa Vena Cava?

Muganga wawe afite ibizamini byinshi kugira ngo arebe uko Vena Cava imeze. Bimwe muri byo birimo:

• X-ray yo mu gituza (iyi ikoreshwa mu kureba vena cava iruta izindi).
• Angiografiya y'imitsi yo mu mutima (ibi bishobora no kureba vena cava ihanitse).
• Isuzuma rya Ultrasound.
• Ikizamini cya CT Scan (CT - Computed Tomography).
• Ikizamini cya MRI (MRI - Magnetic Resonance Imaging).
• Ishusho y'imitsi itandukanya imiterere y'umubiri cyangwa phlebography (iyi ni X-ray y'imitsi, ariko ntabwo ikoreshwa cyane).

Ni ubuhe buryo bwo kuvura ibibazo bifitanye isano na Vena Cava?

Mu gihe cyo kuvura ikibazo hakoreshejwe vena cava ya superior (SVC) cyangwa vena cava ya inferior (IVC), uburyo nk'ubwo bwo kuvura bukunze gukoreshwa.

• Imiti igabanya ubukana bw'amaraso ( imiti itera kwihagarika cyane) cyangwa imiti igabanya ubukana bw'amaraso ishobora gutangwa kugira ngo ivure kubyimba.
• Imiti ya Steroid , imiti igabanya ububabare bw'amaraso (thrombolytics ), hamwe n'imiti igabanya ububabare bw'amaraso (imiti ibuza amaraso kuzura) ishobora gutangwa kugira ngo ivure ibibazo nko kuzura kw'amaraso.
• Udukoko tw'amaraso dushobora gukurwaho hakoreshejwe catheter .
• Iyo imitsi igabanutse (stenosis) bitewe no kuzura kw'amaraso, hashobora gukorwa angioplasty (gukanda ahantu hafunganye ku rukuta rw'imitsi) hanyuma hagashyirwaho stent ( umuyoboro muto w'icyuma).
• Iyo amaraso yanduye cyangwa ikibyimba , hashobora gukorwa operasiyo yo kubaga .
• Iyo hari ikibyimba, gishobora gukurwaho hakoreshejwe uburyo bwo kubaga.
• Uburyo bwo kuvura kanseri hakoreshejwe imiti igabanya ubukana cyangwa imirasire bushobora gutangwa kugira ngo buvure kanseri.

Nanone, niba ufite Deep Vein Thrombosis (DVT) (indwara ituma amaraso acika mu maguru) kandi ukaba ufite ibyago byo kurwara amaraso ava mu maguru cyangwa mu kibuno ajya mu bihaha (byitwa pulmonary embolism (PE) , muganga wawe ashobora gufata icyemezo cyo gushyiramo Vena Cava filter . Iyi filter ifata amaraso acika kandi ikayabuza kujya mu bihaha.

Ni gute wakora Vena Cava yawe ikagira ubuzima bwiza?

Kimwe n'indi mitsi y'amaraso mu mubiri wawe, ushobora kwita kuri iyi Vena Cava.

• Kurya indyo yuzuye irimo ibinure byinshi.
• Gukora imyitozo ngororamubiri buri gihe.
• Gabanya stress.
• Kugenzura indwara nk'umuvuduko ukabije w'amaraso , cholesterol nyinshi, na diyabete .

Amaherezo, ikintu cy'ingenzi kurusha ibindi

Niba ufite ikibazo cyo kuziba kwa vena cava (SVC) cyangwa inferior vena cava (IVC), muganga wawe afite amahitamo menshi yo kuyivura. Muganire ku buryo bwiza bwo kuvura indwara yawe. Niba muganga wawe aguhaye imiti, fata neza nk'uko byategetswe. Niba warabazwe cyangwa ubundi buryo bwo kuvura, menya neza ko ukurikiza gahunda za muganga kugeza igihe uzaba wakize neza. Ubuzima bwawe buri mu maboko yawe!
