Ukususwa kwe-Aortic kuyisifo esiyingozi esidinga ukuhlala esibhedlela ngokushesha. Izibalo zibonisa ukuthi ukushona uma kungekho ukuphathwa ngendlela efanele kungu-65-70%, kanti ngisho nalapho kunakekelwa ukwelashwa, inani lokufa liphakeme.
Izimbangela eziyinhloko ze-aortic dissection
I-aneurysm iyinhlanganisela yodonga lwesitsha segazi ngenxa yokuncipha kwayo, noma iqoqo lama-cholesterol plaques. Uma kwenzeka ukuthi i-aneurysm iphule ubuqotho bendonga yangaphakathi yodonga lwe-aortic, intima, igazi kancane kancane liqala ukungena phakathi kwesikhala esingaphakathi nongaphakathi odongeni, kancane kancane ukulukhuphula kancane kancane. Sekule ndawo, isiguli sidinga ukunakekelwa esibhedlela ukuze sigweme ukulimala okunye e-aorta. Ngeshwa, kungenzeka ukuthola ukuklanywa okwamanje kule ngqungquthela kuphela, ngesikhathi kuhlolwa jikelele isimo sezempilo semvelo.
Kamuva, igazi phakathi kwezingxenye zodonga lwezitsha luyaqhubeka, futhi luya phakathi kwezingxenye eziphakathi naphakathi kwe-aorta. Uma kukhona ukuphazamiseka okuphelele, umuntu kungenzeka afe ngenxa yokuphuma kwegazi ngaphakathi noma ukushaywa ubuhlungu. Ngakho-ke, kubalulekile hhayi kuphela ukuxilonga lesi sifo ngokuhamba kwesikhathi, kodwa futhi nokuqaphela ukuthi kungenzeka yini ingozi.
Ngokuvamile, i-aortic aneurysm dissection ine-genetic predisposition, ngakho-ke uma kunezimo ezinjalo emndenini wakho, kufanele uqaphele. Izici ezivusa amadlingozi nezifo ezihlukahlukene eziguquguqukayo. Nasi uhlu lwezigaba zabantu abasengozini kakhulu:
- abantu abangaphezu kuka-60;
- amadoda amnyama;
- Iziguli ezinenhliziyo nesifo se-vascular;
- abantu abaningi kakhulu;
- izidakwa, izidakamizwa;
- iziguli ezine-syphilis kanye nezinye izifo ezibhekene nezicubu ze-necrosis;
- iziguli eziphezulu;
- abadlali.
Abamele lesi sigaba sokugcina kufanele bakhulume ngokwehlukana. Abantu abathintekayo ngokwezemidlalo ngokuvamile banomthwalo okhulayo wokusebenza emsebenzini wesimo senhliziyo, ngakho-ke uhamba ngokushesha kakhulu. Izifo ezithinta abantu abaneminyaka engama-60-70, zitholakala kumgijimi oneminyaka engu-40 ubudala nabagibeli. Isizathu se-dissection ye-aorti singase sibe ukuhlukumezeka okukhulu kakhulu esifundeni se-thoracic.
Izimpawu eziyinhloko ze-aortic dissection yizinhlungu ezivuthayo, ezingenakubekezelelwa enhliziyweni nasendaweni ye-lesion, ukwehla kwipulse ngokucindezela okwandayo. Kukhona neze ezinye izimpawu zalesi sifo.
Ukwelashwa kwe-aortic dissection
Ukwelashwa kwesikhwama kusho ukutholakala esibhedlela kanye nokungenelela okusheshayo. Ukuhlinzwa kuphela kuzosiza ukuyeka ukuqhuma kwe-aortic okuqhubekayo nokuqhekeka okuphelele, ngisho nengxenye yehora lokubambezeleka kungadala impilo yesiguli. Uma lesi simo singabalulekile futhi igazi phakathi kwezindonga ze-aorta lingasuswa ngendlela ehlukile, kuzodingeka ukuthi kube khona ukwelashwa okunomsoco okubandakanya ukuqinisa izindonga zemithambo yegazi nokuncipha kwengcindezi yegazi. Lokhu kuzokwandisa impilo yesiguli iminyaka engu-10-15, kodwa uma i-stratification isiqalile kakade,
Kuye indawo yendawo ethintekile, ungenza ukubikezela okunye:
- Ngokuhlukaniswa kwe-aorta ye-thoracic, izinga lokusinda liphansi kakhulu, njengoba liphazamisa umjikelezo omncane wokusabalalisa futhi kungabangela ukuboshwa okuphelele kwenhliziyo. Kule nkinga, ubuhlungu buzofana nobuhlobo nokuqina kwe- infarction ye-myocardial kanti udokotela onolwazi uzofaka ngokushesha ukuxilongwa okufanele, ukuthumela isiguli ekuhlinzekeni.
- Ukwakhiwa kwe-aorta yesisu ngokuvamile kuvame ukungabonakali kahle, isifo sobuhlungu senzeke ngokuhamba kwesikhathi, esiyinkimbinkimbi yokuxilongwa. Lolu hlobo lwesifo aluyingozi kakhulu, kodwa kubalulekile ukusola ngokuhamba kwesikhathi into engalungile bese yenza i-MRI noma i-tomography.
