Izindonga zemithambo yegazi zibuthakathaka ngenxa yezizathu ezihlukahlukene, amafayili alahlekelwa ukuqina kwawo, okugcina ekuholela ekuvukeni. Ngaphandle kokwelapha, lesi sifo siphelela ngokuqala ngokukhipha imithi, bese kuthiwa uphelelwe ngokuphelele umthambo ongaziphapha ngaphakathi. Njengoba umuthi wezokwelapha ubonisa, i-aneurysm ejwayelekile kakhulu ye-aorta yesisu isingama-75% kuwo wonke amacala okuphazamiseka kwegazi.
I-Aneurysm ye-aorta yesisu - izimbangela
Ukulimala nokunciphisa izindonga zemithambo yegazi kubangela:
- ukucindezeleka komzimba;
- izifo zenyama ezithathelwanayo, ezimaza emithanjeni nasemithanjeni, ngokwesibonelo, ukuphilisa ;
- ukutholakala kwesifo sengculaza , ngoba lesi sifo sikhuthaza ukuchithwa kwe-cholesterol (lipid plaques) ezindongeni zezimpahla, okuholela ekusenikeni kwe-lumen nokunyuka kwengcindezi phakathi nokugeleza kwegazi;
- i-aortitis;
- izifo zofuzo ezihlotshaniswa nezinguquko kuzicubu ezixhunyiwe.
I-Aneurysm ye-aorta yamathumbu - izimpawu
Uphawu oluvame kakhulu futhi oluvame ukwenzeka kakhulu lomonakalo we-artery ubuhlungu be-syndrome. Uvela ngakwesobunxele kwesisu nangendawo eseduze neveli, angakwazi ukugcoba ngemuva, ikakhulukazi emhlane ongezansi. Ngaphezu kwalokho, ubuhlungu ngezinye izikhathi buhlinzeka ekuguleni, emilenzeni engezansi nasezintweni. Ukungahambi kahle ngokuvamile kuvambela i-paroxysmal, nakuba ezinye iziguli zikhalaza ngesifo sosizi esiqhubekayo. Lesi sibonakaliso sibangelwa ngenxa yecindezelo eyenziwa ngodonga oluthile lwe-aortic, ezimpandeni zezinzwa zomgogodla, kanye ne-plexuses ye-nerve esikhaleni se-retroperitoneal.
Izici ezengeziwe:
- umzwelo we-pulsation eqinile esiswini;
- ukuvula;
- ukuzwa ubunzima ngaphezu kwenkaba;
- ukunciphisa ukudla;
- ukuhlanza kanye nokucabangela;
- ukuqunjelwa okungapheli;
- ukwehla kwesisindo somzimba.
Kokubili i-aneurysm evamile kanye neyokuphefumula ye-aorta yesisu ingathuthuka kalula, ngezinye izikhathi ihambisane nobuhlungu obukhulu esiswini nasezindaweni zamathumbu. Ngakho-ke, iziguli ngokuvamile azihambi esibhedlela ukuze zithole usizo, zichaza lesi sigameko nge-indigestion ejwayelekile.
Ukuhlukana kwe-Aneurysm kwe-aorta yesisu
Njengomthetho, ngesikhathi kuqhuma ngokuphelele umthambo, ukuphuma kwangaphakathi kwangaphakathi kwenzeka, okuhambisana nesimo sokuphazamiseka kwesiguli. Cishe wonke amacala aqeda umphumela obulalayo ngenxa yokulahlekelwa okukhulu kwegazi. Ngokwezifundo zezokwelapha, uma ububanzi be-aneurysm ye-aorta yesisu buyi-5 cm noma ngaphezulu, ingozi yokuphuka kwayo iyakhula kuma-70%. Ingozi enkulu ukuthi akunakwenzeka ukubikezela umzuzu wokuphuka kunoma yiziphi izimpawu noma izimpawu zomgomo.
I-Aneurysm ye-aorta yesigxobo esiswini - ukwelashwa
Njengoba kunikezwa ukuthi lesi sifo esibuzwayo asivame ukutholakala esiteshini sokuqala, ayikho imithi noma enye yokwelashwa okulondolozayo. Ukwelashwa kwe-aneurysm ye-aorta yesisu kwenziwa kuphela ngendlela yokuhlinzwa.
I-Aneurysm ye-aorta yesigxobo esiswini - ukusebenza
Okusemqoka kokungenelela kokuhlinzwa ukukhipha ingxenye ehlanganisiwe ye-aorta ewonakele kusukela ekuphumeni kwegazi okuphelele. I-lumen engekho ifakwe esikhundleni se-prosthesis ekhethekile eyenziwe ngezinto zokwenziwa, okufakwa phakathi kwezindonga ezinempilo yesitsha segazi. Ezimweni lapho ukwandiswa kwemithambo ye-aliac kwenzeka khona futhi ukuhanjiswa kwendonga ka-aorti kuyaqhubeka, kusetshenziselwa i-bifurcation ehlangene emaphethelweni e-prosthesis.
Ukusebenza kwenziwa ngaphansi kwe-anesthesia jikelele futhi kuphephile, ngoba isisusa esisekelwe i-aortic asiyona ingozi ngokuphelele emzimbeni futhi inqatshelwe.
