Tose tinoziva kuti mwoyo wedu ndiwo musimboti mukuru unopomba ropa mumuviri wese. Semuchina wemvura. Saka, ropa rakachena, rine oxygen yakawanda rinopombwa nemoyo uyu rinofanira kunge riine nzira huru yekuparadzira ropa mumuviri wese. Nzira huru, yakakura, uye yakasimba yeropa ndiyo aorta, kana kuti sezvatinoti muchiRungu, 'Aorta'. Nhasi tichataura nezve 'Descending Aorta', inova chikamu chakakosha cheiyi aorta.
Zvichitaurwa zviri nyore, chii chinonzi Descenting Aorta?
'Descending Aorta' ndiyo chikamu chakareba kwazvo cheaorta, tsinga yeropa yakakura kwazvo mumuviri wako. Kudzika zvinoreva 'kudzika'. Saka, sezvinoreva zita racho, ichi ndicho chikamu cheaorta chinodzika. Basa rayo guru kutakura ropa rakachena, rakazara neokisijeni kubva pamoyo richidzika nepachipfuva chako nepadumbu. Zvakafanana nepombi huru yemvura inopa mvura kuguta. Pombi huru iyi inobuda mumapazi madiki kuti ipe ropa kune muviri wese.
Pane zvikamu zviviri pane izvi... chii ichocho?
Kunyangwe tsinga yese yeropa inonzi Descenting Aorta isingachinji, tinotaura nezvayo sezvikamu zviviri zvichienderana nekuti iri kupi. Zvakafanana kana mugwagwa mumwe chete unopfuura nemumaguta maviri, unodanwa nemazita akasiyana muguta rega rega.
1. Kudonha kweMwoto weChipfuva: Kana Mwoto weChipfuva uchipfuura nepachipfuva chako (Chipfuva), tinoudaidza chikamu ichocho kuti 'Kudonha kweMwoto weChipfuva'. 'Chipfuva' izwi rekurapa rinoshandiswa kureva zvinhu zvine chekuita nechipfuva.
2. Kudzika kweAorta yedumbu: Tsinga iyi yeropa inochinja zita rayo painopfuura nepadiaphragm, mhasuru inoparadzanisa chipfuva chako nedumbu. Chikamu chiri pasi pediaphragm, chiri mukati medumbu rako, chinonzi Kudzika kweAorta yedumbu. Inotangira pamusoro pedumbu rako kusvika padanho reguvhu rako.
Usazvisanganisa nezvimwe zvikamu zve aorta!
Dzimwe nguva zvikamu zve aorta zvinogona kuvhiringika. Ngatitsanangurei izvozvo zvakare.
- Ko Thoracic Aorta neDescendeng Aorta zvakafanana here?
Kwete. Izvi hazvisi chinhu chimwe chete. Izwi rekuti 'Thoracic Aorta' rinoreva chikamu chose cheaorta chinofamba nepachipfuva. Chinosanganisira zvikamu zvakati wandei:
- Mudzi weAortic: Chikamu chemudzi chakabatana nemoyo.
- Kukwira kwemoyo: Chikamu chinotangira pamoyo chokombamira kumusoro.
- Aortic arch: Chikamu chakakombama chiri pamusoro, chakaita semubato wetsvimbo.
- Kudonha kwemoyo wechipfuva: Ichi chikamu cheKudonha kwemoyo wechipfuva chatiri kutaura nezvacho chiri mukati mechipfuva.
Izvi zvinoreva kuti, chikamu cheDrescending Aorta ndeche Thoracic Aorta.
- Ndeupi musiyano uripo pakati peAorta Inokwira neAorta Inoburuka?
Izvi zviri nyore kwazvo. Funga nezve aorta semubvunzo mukuru (?).
- Chikamu chinokwira chemoyo (ascending aorta) ndicho chinokwira kubva pamoyo.
- Chikamu chinodzika che aorta ndicho chinodzika mushure mekukombama ikoko. Chinotangira pachipfuva kusvika mudumbu.
Chii chinoitwa neDescenting Aorta kumuviri wedu?
Iyi ndiyo nzira huru inopa ropa kuchikamu chezasi chemuviri wedu. Izvi zvinoita kuti mitsipa midiki yeropa (matavi) ibude mairi ndiyo inoita kuti nhengo dzedu dzakawanda dzigamuchire okisijeni nezvinovaka muviri.
| Masisitimu makuru nenhengo dzinogamuchira ropa | Tsananguro iri nyore |
|---|---|
| Sisitimu yekugaya chikafu | Inopa ropa kunhengo dzemuviri dzakadai segurokuro, dumbu, ura hudiki nehukuru. |
| Itsvo | Inopa ropa rinodiwa kuitsvo, iro rinosefa tsvina kubva mumuviri. |
| Madziro ekufema nepachipfuva | Inopa ropa kumapapu netsandanyama dzechipfuva. |
| Sisitimu yekubereka | Inotakura ropa kuenda kumazai evakadzi uye machende evarume. |
| Muzongoza (muzongoza) | Inopa ropa kumusana, chikamu chakakosha chetsinga dzedu. |
| Makumbo | Chubhu iyi inozopedzisira yapatsanuka kuita zvidimbu zviviri yova tsinga huru inotakura ropa kuenda kumakumbo. |
Ngatidzidzeiwo nezvehukuru uye zvidimbu zvetsinga iyi yeropa.
Saizi yeaorta inogona kusiyana zvishoma zvichienderana nezera, saizi yemuviri, uye murume kana mukadzi. Mumunhu mukuru ane hutano hwakanaka, avhareji ye
- Dhayamita yeaorta inodonha pachipfuva inowanzova masendimita 2.5 - 3 .
- Dhayamita yeaorta inoburuka mudumbu inowanzoita masendimita maviri .
Tsinga iyi yakasimba yeropa inoumbwa nezvikamu zvitatu zvikuru zvenyama:
1. Rutivi rwemukati (Tunica Intima): Ropa rinoyerera nepakati perutivi urwu. Rinobatsira kudzora BP nekudzivirira kuumbwa kweropa.
2. Rutivi rwepakati (Media): Rutivi urwu rune tsandanyama diki uye shinda dzinopfava dzinobatsira kuti ropa rirambe richifamba munzira imwe chete. Rutivi urwu runogona kupera simba nekukura.
3. Rutivi rwekunze (Adventitia): Apa ndipo panowana simba nechimiro chetsinga yeropa.
Ndezvipi zvirwere zvinokanganisa Descenting Aorta?
Nekuti inoita basa rakakosha kudaro, kukuvara kwetsinga iyi yeropa kunogona kuva kwakakomba zvikuru. Dambudziko rinowanzoitika i aortic aneurysm .
Zvichitaurwa zviri nyore, aneurysm inzvimbo isina kusimba iri mumadziro etsinga yeropa, zvichiita kuti ibude sebharumu. Izvi zvinokura zvishoma nezvishoma uye zvinogona kuputika rimwe zuva.
Kune mhando dzakasiyana dzeaneurysms dzinoitika mu descending aorta:
- Kurwara kwetsinga dzemuchipfuva (TAA): Izvi zvinoitika mutsinga dzemudumbu dzinodzika muchipfuva. Kukwira kweropa, kukuvara kwechipfuva, uye mamwe matambudziko ekuberekwa (semuenzaniso Marfan Syndrome) zvinogona kukonzera izvi.
- Abdominal Aortic Aneurysm (AAA): Iyi ndiyo mhando yeaneurysm inonyanya kuwanikwa. Inowanikwa mudumbu. Inonyanya kuwanikwa muvanhu vane makore anopfuura 65, kunyanya varume vanoputa fodya . Chikonzero chikuru ndechekuwanda kwemafuta mutsinga dzeropa.
- Thoracoabdominal Aortic Aneurysm (TAAA): Iyi i aneurysm inotangira pachipfuva ichienda mudumbu.
Kana chiremba akawana aneurysm yakaita seiyi, acharamba achiiongorora kuburikidza nekuskena. Kana ikakura kusvika pakukura kune njodzi, achatsvaga kurapwa matambudziko asati aitika.
Matambudziko maviri ane njodzi zvikuru:
1. Kuputika kweAneurysm: Chikamu chakazvimba cheaneurysm chinoputika. Izvi zvinogona kukonzera kubuda ropa rakawanda mumuviri uye kunyange kufa ipapo ipapo.
2. Kuchekwa kweAortic yerudzi rweB (kubvaruka kwemadziro):Kutsemuka kwemukati metsinga yeropa, zvichiita kuti ropa ribude nepaburi richipinda munzvimbo iri pakati pemadziro maviri. Izvi zvinogonawo kukonzera kuti tsinga yeropa itsvuke kana kumisa kufamba kweropa kuenda kunhengo dzemuviri.
Mamiriro ese aya enjodzi dzekurapa dzinoda kurapwa nekukurumidza . Kana paine kusava nechokwadi kudiki, zvakakosha kuenda kuEmergency Treatment Unit (ETU) yechipatara nekukasika.
Ndezvipi zviratidzo zvezvirwere izvi?
Chinhu chinotyisa apa ndechekuti kazhinji, zvirwere zvakaita seaneurysms hazviratidzi zviratidzo pakutanga . Izvi zvinoreva kuti unogona kuva nechirwere chine njodzi chinoitika mumuviri wako pasina matambudziko. Ndosaka zvichikosha kuona chiremba nguva nenguva kuti aongororwe.
Zvisinei, zvimwe zviratidzo zvinonyevera zvinogona kuonekwa kana aneurysm yava kuda kuputika.
| Chiratidzo | Tsananguro |
|---|---|
| Zviratidzo zvekunyevera kuti aneurysm yava kuda kuputika | |
| Kurwadziwa kwemudumbu | Zvinonzwa sekuti moyo uri kurova mudumbu mako. |
| Kurwadziwa kunogara kwenguva refu | Kurwadziwa kunogara kuripo kumusana, kumagaro, muzvidya, mumakumbo, kana mudumbu. |
| Kuzara kwedumbu | Kunzwa kuguta zvakanyanya kunyangwe mushure mekudya zvishoma. |
| Kuoma kufema | Kunzwa kushaya mweya kana kuoma kufema. |
| Zviratidzo zvinoda kurapwa nekukurumidza (Aneurysm Rupture / Dissection) | |
| Kurwadziwa kwakakomba kamwe kamwe | Kurwadziwa kusingatsungiririki muchipfuva, kumusana wekumusoro, kana mudumbu kunoita sekunge kubaya kana kubvarura banga. |
| Dzungu uye kusuruvara | Dzungu , maziso ebhuruu, kana kufenda. |
| Zvimwe zvinhu | Kudikitira, kurova kwemoyo nekukurumidza, kurutsa, kuoma kutaura, kusanzwa simba kune rumwe rutivi rwemuviri. |
Kana ukaona chimwe chezviratidzo izvi zvekukurumidzira, usapedza nguva uye fonera amburenzi nekukasika woenda kuEmergency Treatment Unit (ETU) yechipatara. Sekondi yega yega inokosha.
Zvirwere izvi zvinoonekwa sei?
Kana chiremba wako achifungidzira izvi mushure mekukuongorora, vachakukurudzira kuti utarise kuti une chirwere ichi here kana kuti kwete.
- Kuongororwa kweUltrasound yedumbu
- Kuskena kweComputed Tomography Angiography (CTA)
- Kuskena kweMagineti Resonance Imaging (MRI)
- Kuvhiyiwa kwemoyo kuburikidza neTransesophageal Echocardiogram (TEE)
Miedzo iyi inogona kuona zvakajeka saizi, chimiro, uye kana paine kuzvimba kana kubvaruka kwetsinga yeropa.
Ndezvipi zviri kurapwa?
Kurapwa kunoenderana nehukuru hweaneurysm yako, kukura kwayo nekukurumidza, uye hutano hwako hwese.
- Kuongorora: Kana aneurysm iri diki, chiremba anogona kuiongorora nguva nenguva kuti aone kana iri kukura.
- Mishonga: Mishonga inopiwa kudzora BP uye huwandu hwecholesterol mumuviri. Izvi zvinogona kuderedza mwero wekukura kweaneurysm.
- Kuvhiyiwa: Kana aneurysm yakakura zvine njodzi, kuvhiyiwa kunoitwa kubvisa chikamu chisina simba uye kuchitsiva nemudziyo wekugadzira (graft).
- Kugadziriswa kweEndovascular Aneurysm (EVAR): Iyi inzira isinganyanyi kupindira mumuviri. Chidimbu che stent chinoiswa kuburikidza nekucheka kudiki mudumbu uye chinowedzerwa pamusoro pe aneurysm. Izvi zvinobvumira ropa kuyerera nemutsinga mutsva, zvichideredza kumanikidzwa pamadziro akazvimba.
Mharidzo Yekuenda Nayo Kumba
- Descendeng Aorta ndiyo nzira huru inopa ropa kuchikamu chezasi chemuviri wedu.
- Aortic aneurysm chirwere chinoitika apo tsinga iyi yeropa inoshaya simba uye inoputika sebharumu. Izvi zvinogona kusaratidza zviratidzo pakutanga.
- Kusvuta fodya neBP zvakanyanya ndizvo zvinokonzera zvirwere izvi.
- Kurwadziwa kusingatarisirwi muchipfuva kana mudumbu chinhu chinotyisidzira hupenyu. Enda kuchipatara nekukasika.
- Nekutevera mararamiro ane hutano (kudya zvakanaka, kurovedza muviri, uye kusasvuta), unogona kuchengetedza hurongwa hwako hwese hwemwoyo, kusanganisira aorta yako, hune hutano.
- Kana uine zvinhu zvine njodzi (semuenzaniso, nhoroondo yemhuri yeaneurysm, BP yakakwira, kusvuta), taura nachiremba wako nezvazvo uye uwane bvunzo dzinodiwa.
