Vula i-arterial traction - rhoqo isifo senhliziyo

Phakathi kokungabikho kokuzalwa komzimba we-cardiovascular system, i-arterial traction ihlala kwindawo ekhethekileyo, ngokuqhelekileyo ibe nobuhlobo obungathandabuzekiyo kunye nokungaqhelekanga kwimizimba, kuba akukho ziintlupheko ezibalulekileyo zesakhiwo kunye nokusebenza kwentliziyo ngesifo. Ngokuqhelekileyo, eli duct, edibanisa ukuhla kwe-aorta, ethwala igazi kuzo zonke izitho zomntwana okhulayo, kunye ne-pulmonary umthambo apho igazi ligeleza kwimiphunga, luyimpawu ezibalulekileyo zohlobo lwe-embryonic of circulation. Kwaye ngexesha le-ultrasound yowesifazane okhulelweyo, ufunyanwa kuwo onke abantwana esibelethweni.

Ukusebenza kombhobho osebenzayo ngokuqhelekileyo kusebenza ngokuqhelekileyo?

Enyanisweni, ukuthetha ukuba umntwana unomzila ovulekileyo wokusebenza, unokuphela kuphela ekupheleni konyaka wokuqala wobomi bentsana-ukuphuma kwegazi kulo mhlaba phantsi kweemeko eziqhelekileyo buthathaka emva kokuqala kokutshatyalaliswa kwintsana kunye nokuphela ngokupheleleyo kwiinyanga ezi-2-3 zobomi. Kodwa ukutsho ukuba le ntsilelo yenkqubo yokujikeleza ikhona, inokwenzeka kuphela kwiinyanga ezimbalwa - kwezinye iimeko, isantya sokutshatyalaliswa kwayo sinciphisa, ingakumbi kubantwana abazalelwe ngaphambi kwesikhathi.

Isizathu sokuvalwa kwesitya segazi phakathi kwe-aorta kunye ne-pulmonary artery ukusabalalisa imiphunga nokuqala kokuphefumla nge-oksijeni yemoya. Kwiimeko eziqhelekileyo, izinga lexinzelelo kwi-pulmonary artery kunye ne-aorta lilingana, okwenza izinto ezifunekayo zokumisa uxhamlwano oluhambelanayo nomjikelezo omkhulu wegazi. Ngokugqithiseleyo, i-arterial traction iyaqhubeka isebenza kubantwana abazalwa ngaphambi kokudala - abanalo ixesha lokuba benze ngokuqhelekileyo iimpahla zamaphaphu kunye nezicubu zamaphaphu, ejongene nokutshintshiselwa kwegesi emzimbeni, kunye neentsana ezinokusuleleka kwiinkampani ezithathelwanayo, ezibandakanya amayeza Intsholongwane kaRubella. Kule meko, akukho phuhliso oluqhelekileyo lwesalathisi se-muscular ye-wall walls, ngoko ke umzila ungasolo uvulekile.

Indlela i-arterial duct ibonakala ngayo

Ngaphandle kwindlela yokuhlala evulekile ebantwini kubonakaliswa ngumfanekiso oqhakazileyo weklinikhi - ngokuqhelekileyo, kunye nobubanzi obuncinane besitye esithethayo, uphuhliso lomzimba aluphuli kwaye akafani neontanga zakhe. Abantwana bayakwazi ukunyamezela imithwalo yempahla eyaneleyo kwiminyaka yabo, kodwa ngaba abantwana abanempilo kaninzi banesifo se-catarrhal, i-bronchitis kunye ne-pneumonia.

Kwimeko apho i-arterial traction ine-diameter eyaneleyo, iinguqu ezimbini zokuphuhlisa iziganeko ziyakwenzeka. Eyokuqala, ukuphazanyiswa okulula kokusebenza ngokuqhelekileyo kwenkqubo yokujikeleza, kuqhutywe umthamo ophezulu wegazi, apho umgangatho oqhelekileyo we-oksijeni, kwi-pulmary artery kunye nokuqhubela phambili, emithanjeni yegazi yemiphunga. Ngako oko, ukubuya kwegazi ngokusebenzisa isangqa esincinci sokujikeleza ukuya kwi-atrium yekhohlo kunye nokwanda kwe-ventricle, kunye nokunyuka kancane kwe-muscular layer. Kukho ukwehla ekunyamezelweni kwemisebenzi yomzimba, izibonakaliso zentuthuko yomzimba zibi kakhulu, izifo ezivuthayo zamaphaphu zenzeka ngezihlandlo eziliqela kwixesha okanye ziya kwinqanaba lesifo esingapheliyo, kodwa imeko epheleleyo yomzimba ayifuneki ixesha elide, kuba izinga le-oksijini egazini lihlala liqhelekileyo. Okwesibini, ukuhluka okugqithisileyo kokuphuhliswa kwesiphene, igazi likhutshwa kwisangqa esincinci sokujikeleza kwegazi ukuya kummandla omkhulu, ukubunjwa kwegesi kwegazi kuphazamiseka kakhulu , kwaye ngenxa yoko, iinkqubo ze-metabolism kwizicubu. Kukho igalelo ekuphuculweni komzimba, i-cyanosis kunye ne-pallor yesikhumba, ukuphucotha iqondo lokuphuhlisa.

Inkqubo yokonyango kwe-arterial tract

Kwinkoliso yamatyala amaninzi, kungakhathaliseki ukuba ubukhulu besiphene, i-arterial traction kufanele iphathwe ngokukhawuleza. Okwangoku, kunokwenzeka ukwenza usebenziso olusilula lula kwiinqanawa eziphambili - ngaphandle kokuchaphazela intliziyo (ukuyeka) kunye nezinye iindlela zokungenelela, i-ligation yendlela yokusebenza eyenziwa. Kwiimeko zamanqanaba ezinje zomoya, kunokwenzeka ukwenza imisebenzi yokugcina i-endovascular - ukuvalwa kwendlela yokutya ngokuncedisa i-intravascular spiral or obturator.
