Ka tuyige ku ‘omusuwa’ omukulu ogw’omutima gwo (Ascending Aorta) n’obukulu bwagwo.

Leero tugenda kwogera ku kitundu ky’omubiri gwaffe ekikulu ennyo era wadde nga kiyinza okulabika ng’ekizibu katono, eky’angu ennyo okutegeera. Oyo ye (Ascending Aorta) . Mu ngeri ennyangu, kino kye kitundu ekisooka eky’omusuwa omukulu, (Aorta) , ogutandikira ku mutima gwaffe ne gugabira omusaayi mu mubiri gwonna. Kiringa ekitundu ekiteekebwa mu payipu enkulu ekireeta amazzi okuva mu ttanka y’amazzi okutuuka mu nnyumba. Kale, ka tulabe kino (Ascending Aorta) kye ki, kiki ekikituukako, endwadde za ngeri ki gye kiyinza okuleeta, n’engeri y’okukikuuma nga kiramu.

(Ascending Aorta) kye ki? Kivaako ki?

Teebereza nti omubiri gwaffe gulinga ekibuga ekinene. Buli nnyumba, buli dduuka, buli kifo mu kibuga kino kyetaaga amazzi. Mu ngeri y’emu, buli katoffaali mu mubiri gwaffe bwetaaga omusaayi omuyonjo ogujjudde omukka gwa oxygen. Ani akuba omusaayi guno mu mubiri gwonna? Omutima gwaffe. Omusaayi omutima gwe gukuba gutambuzibwa mu mubiri gwonna omusuwa omukulu, ogusinga obunene (Aorta) , oba omusuwa omunene.

Kati eno (Aorta) erina ebitundu ebiwerako.

1. (Ascending Aorta): Kino kye kitundu ekigenda waggulu nga kifuluma mu kisenge ekikulu ekipampagira omusaayi ekiyitibwa Left Ventricle ku ludda olwa kkono olw’omutima. Ono ye protagonist waffe leero.

2. (Aortic Arch): Olwo ttanka eno n’efukamira waggulu ng’omukono gw’omuggo. Kiyitibwa (Aortic Arch).

3. (Descending Aorta): Olwo ttanka eno n’egenda wansi, ng’eyita mu kifuba, ng’eyita mu lubuto. Ekitundu ekyo kiyitibwa (Descending Aorta).

Kale, omulimu omukulu ogwa (Ascending Aorta) kwe kutwala omusaayi ogulimu omukka gwa oxygen ogussibwa omutima ne gutandika okugusaasaanya mu (Aortic Arch) n’okuva awo okutuuka ku mubiri gwonna. Okusingira ddala, emisuwa ebiri emikulu ennyo egiyitibwa Coronary Arteries egigabira omutima omusaayi gitandikira ku kino (Ascending Aorta). Teebereza, ppampu y’amazzi nayo yeetaaga amazzi okukola, bw’etyo bw’ekola.

Kino (Ascending Aorta) kisangibwa wa? Kirabika kitya?

Kino (Ascending Aorta) kisangibwa mu kifuba kyaffe, naddala eggumba eddene wakati mu kifuba, emabega wa (Sternum) , ku kkono w’omutima. Kiyungibwa butereevu ku (Left Ventricle) y’omutima era kigaziwa waggulu.

Mu ndabika, omusuwa gwonna gulabika ng’omuggo gumu omutono. Omusuwa ogulinnya (ascending aorta) kye kitundu ekisinga obumpi mu muggo ogutandikira okumpi n’omutima ne gugenda waggulu. Aortic arch kye kitundu ekifukamira ng’omukono gw’omuggo.

Ascending Aorta etera okuba wakati wa sentimita 5 ne 8 (yinsi nga 2 ku 3) obuwanvu ate nga sentimita 3 ku 4 obugazi. Bukendeera mpolampola mu bugazi nga bwe bugenda wansi mu kifuba.

Bitundu ki ebiri mu Ascending Aorta? Kitondebwa kitya?

Omusuwa gwonna gwawuddwamu ebitundu bibiri ebikulu: omusuwa gw’ekifuba n’omusuwa gw’olubuto.(Ascending Aorta), (Aortic Arch), ne (Descending Aorta) byegattira wamu ne bikola (Thoracic Aorta).

Ascending Aorta etandikira okumpi ne Aortic Heart Valve, esangibwa emabega wa Left Ventricle. Aortic Valve eno eringa oluggi. Kigguka ne kiggalawo okusobozesa omusaayi okukulukuta okuva mu Left Ventricle okuyingira mu Aorta. Ascending Aorta ekoma nga tetunnatuuka ku Brachiocephalic Artery, ettabi eddene erisooka okuva ku Aortic Arch.

Ascending Aorta erina ebitundu bibiri ebikulu:

1. (Aortic Root): Kino kye kikolo kya (Ascending Aorta), ekitundu ekisinga okumpi ne (Aortic Valve). Munda mu kino mulimu obutuli obutono obulinga bbaatule obuyitibwa (Aortic Sinuses) . Wano we watandikira emisuwa egya ddyo ne kkono (Coronary Arteries) (emisuwa egigabira omutima omusaayi). Wano era we wali (Sinotubular Junction - STJ) . STJ we wava (Ascending Aorta) okufuuka ttanka eya bulijjo.

2. Tubular (Ascending Aorta): Kino kitandika oluvannyuma lwa STJ ne kigenda mu maaso okutuuka ku Aortic Arch. Tewali musuwa mulala guva mu kitundu kino.

Okufaananako n’ebitundu ebirala eby’omusuwa, omusuwa ogugenda waggulu gukolebwa layeri ssatu ez’ebitundu by’omubiri. Kilowoozeeko nga payipu, nga erina layers ssatu:

• (Tunica Intima): Eno ye layeri esinga munda. Omusaayi gukulukuta mu kino.
• (Media): Eno ye layeri eya wakati. Kirina ebiwuzi bingi ebiyitibwa elastic fibers. Bino bisobozesa (Aorta) okukonziba n’okugolola okusinziira ku puleesa. Kyokka ekiseera bwe kigenda kiyitawo, ebiwuzi bino bisobola okunafuwa ne ekisenge ne kigonvuwa.
• (Adventitia): Eno ye layeri esinga ebweru. Kirimu obusuwa obutonotono obugabira bbugwe wa (Aorta) ebiriisa.

Mu ngeri ennyangu, Ascending Aorta ‘ekitundu kya payipu’ kikulu nnyo, eky’amaanyi ekisooka okufuna omusaayi okuva ku mutima ne gutandika okugusindika mu mubiri gwonna.

Endwadde ki ezikwata ku Ascending Aorta?

Ebyembi, ekitundu kino ekikulu ennyo nakyo kisobola okufuna endwadde ez’enjawulo. Ka tulabe ebikulu bye biruwa:

• Aortic Aneurysms: Kino kizibu kya bulijjo nnyo. Omusuwa (aneurysm) kwe kunafuwa kw’ekisenge ky’omusuwa, ekiguviirako okubumbulukuka ng’akapiira. Ebitundu ebisoba mu 50% eby’emisuwa gy’omusuwa mu kifuba bibaawo mu musuwa ogugenda waggulu. Ziyinza okubeera mu kikolo ky’omusuwa oba mu musuwa ogulinnya mu nseke. Aortic aneurysms mbeera eziteeka obulamu mu matigga. Kino kiri bwe kityo kubanga emisuwa giyinza okuleeta amaziga mu layers z’omusuwa – embeera eyitibwa aortic dissection . Oba, singa ekutuka ddala, omusaayi ogw’amaanyi guyinza okuvaamu munda mu mubiri. Kino kya mangu.

• (Okuzimba kw’omusuwa gw’omusuwa):Wadde nga Aortic Valve si kitundu kya Ascending Aorta, yeekwata ku bbugwe ow’omunda ow’Aorta Ascending. Aortic Stenosis kwe kufunda kwa Aortic Valve wakati w’ekikolo kya Aortic ne Left Ventricle. Kino kireetera omutima okukola ennyo okusiba omusaayi mu Aorta. Kino kiyinza okuvaako ekinywa ky’omutima okugaziwa.

• (Aortic Valve Regurgitation): Kino kibaawo nga (Aortic Valve) teggadde bulungi. Olwo, mu kifo ky’okugenda mu maaso mu (Aorta), omusaayi gukulukuta ne gudda mu (Left Ventricle). Kino kireetera omutima okukuba omusaayi omungi okusinga ogwa bulijjo. Ekiseera bwe kigenda kiyitawo, omutima guyinza okunafuwa. (Aortic Valve Regurgitation) nayo esobola okubaawo olw’ekitundu kya (Ascending Aorta) okugaziwa.

• Bicuspid Aortic Valve (BAV): Abantu abamu bazaalibwa n’obupapula bubiri mu aortic valve yaabwe mu kifo ky’obusatu. Abantu abalina vvaalu ey’ekika kino bali mu bulabe obw’okulwala emisuwa gy’omusuwa egy’ekika kya ascending aortic aneurysms. BAV etera okuvaako okusannyalala kw’omusuwa, okuddamu okufulumya omusuwa oba byombi.

• Endwadde z’ebitundu ebiyunga: Abantu abalina endwadde nga (Marfan Syndrome) , (Loeys-Dietz Syndrome) , ne (Ehlers-Danlos Syndrome) basobola okufuna ebizibu nga (Aneurysms) kubanga bbugwe w’omubiri (Aorta) asobola okunafuwa.

• Obuzibu bw’okuzimba: Embeera nga Giant Cell Arteritis ne Penetrating Atherosclerotic Ulcers nazo zisobola okwonoona bbugwe w’omusuwa gw’omusaayi.

Wadde ng’obubonero buno buyinza okulabika ng’obutiisa katono, busobola okufugibwa singa buzuulibwa nga bukyali era ne bujjanjabwa obulungi .

Nnyinza ntya okukuuma Ascending Aorta yange nga nnungi?

Ebintu bye bimu by’okola okukuuma omutima gwo n’enkola y’okutambula kw’omusaayi nga bulamu bulungi nabyo birungi eri obulamu bw’omusuwa ogugenda waggulu.

• Lya emmere ennungi era ennungi: Lya emmere erimu sodium (omunnyo), kolesterol n’amasavu amatono. Lya nnyo ebibala, enva endiirwa, emmere ey’empeke, n’ebiwuziwuzi.
• Dduyiro buli kiseera: Kola ekintu ng’okutambula, okudduka oba okuwuga okumala eddakiika ezitakka wansi wa 30 olunaku. Anyweza omutima n’okufuga puleesa.
• Lekera ddala okunywa sigala n’ebintu ebikolebwa mu taaba: Okunywa sigala mulabe omukulu ow’emisuwa. Kinafuya bbugwe w’omusuwa gw’omusaayi n’okwongera obulabe bw’okuzimba emisuwa.
• Okukendeeza oba okulekera awo okunywa omwenge: Omwenge oguyitiridde guyinza n’okwongera ku puleesa n’okwonoona omutima n’emisuwa.
• Okukeberebwa abasawo buli kiseera: Kikulu nnyo okwekebejjebwa buli kiseera ng’omusawo bw’akulagidde naddala ng’olina ebizibu nga puleesa, kolesterol, ssukaali, oba omuntu mu maka go abadde n’obuzibu bw’omusuwa gw’omusaayi.

Ddi lwe nnina okulaba omusawo?

Bw’oba ​​ozuuliddwa ng’olina obulwadde bwa Ascending Aortic Syndrome oba obulwadde bw’omutima obulala, laba omusawo mu bwangu singa ofuna obubonero obupya oba singa obubonero bwo obuliwo bweyongera.

Ekirala, bw’ofuna obubonero bumu oba obusingawo ku buno wammanga, kayinza okuba akabonero akalaga nti omusuwa gubutuka era olina okugenda mu ddwaaliro ery’amangu mu bwangu:

• Okuziyira oba okuzirika (okuzirika).
• Omutima okukuba amangu.
• Obulumi obw’amaanyi mu kifuba oba mu mugongo ogwa waggulu.
• Okukaluubirirwa okussa.

Tobuusa maaso bubonero nga buno. Okufuna obujjanjabi nga bukyali kiyinza okutaasa obulamu.

Obubaka Obutwala Awaka

Omusuwa ogugenda waggulu kye kitundu ekisooka eky’omusuwa ogusinga obunene mu mubiri gwaffe, omusuwa oguyitibwa aorta. Kiyunga ku mutima era kikola kinene nnyo mu kuyamba okusaasaanya omusaayi ogulimu omukka oguyitibwa oxygen ogussibwa omutima mu mubiri gwonna.

Ebizibu ebimu ku Ascending Aorta, gamba ng’omusuwa ogukutuse, biyinza okutta obulamu. Kale, singa omuntu mu maka go alina ebyafaayo by’obulwadde bw’omutima, oba bw’oba ​​ng’olina emyaka egisukka mu 65, yogerako n’omusawo wo ku ngeri gy’oyinza okukendeeza ku bulabe bw’okufuna obuzibu ku Ascending Aorta. Engeri esinga okwekuuma kwe kubeera n’obulamu obulungi. Faayo omutima gwo, kubanga gukukuuma nga mulamu!
