Mezenteri\u010dna ishemija, predstavlja hroni\u010dno stanje izazvano slabim snabdevanjem creva krvlju, a posledica je su\u017eenja ili blokade jedne od tri glavne arterije koje prokrvljuju crevni sistem. Tako\u0111e mo\u017ee da se javi iznenada usled krvnog ugru\u0161ka koji spre\u010dava dotok krvi i dovodi do pojave iznenadnog bola u stomaku i, re\u0111e, do krvavih stolica. Nedostatak krvi bogate kiseonikom mo\u017ee trajno da o\u0161teti creva. Stoga, ovo stanje zahteva momentalno lekarsko zbrinjavanje. <\/span><\/p>\n

Simptomi<\/span><\/h2>\n

Simptomi akutne mezenteri\u010dne ishemije izazvane krvnim ugru\u0161kom obuhvataju dijareju, iznenadni bol u stomaku i povra\u0107anje, dok simptomi hroni\u010dne mezenteri\u010dne ishemije arterije uzrokovani gubljenjem njene elati\u010dnosti, obuhvataju bol u stomaku nakon obroka i dijareju. \u00a0<\/span><\/p>\n

Mezenteri\u010dna ishemija sastoji se iz tri progresivne faze. One su slede\u0107e: <\/span><\/p>\n

Najpre se javlja hiperaktivna faza, u kojoj su primarni simptomi jak bol u stomaku i pojava krvave stolice. Mnogi pacijenti se oporave i njihova bolest ne napreduje u slede\u0107u fazu;<\/span><\/p>\n

Ukoliko se ishemija nastavi sledi paraliti\u010dna faza; tokom ove faze, bol u stomaku se \u0161iri i na druge delove stomaka koji postaje osetljiv na dodir, a crevna pokretljivost se smanjuje, rezultiraju\u0107i oticanjem stomaka, krvave stolice nestaju, a prilikom pregleda ne mogu se uo\u010diti zvuci crevne pokretljivosti;<\/span><\/p>\n

Kona\u010dno, faza \u0161oka nastaje kada te\u010dni sadr\u017eaj po\u010dinje da isti\u010de kroz o\u0161te\u0107enu crevnu sluzoko\u017eu. Ovo mo\u017ee da rezultira stanjem \u0161oka i metaboli\u010dke acidoze pra\u0107ene dehidratacijom, niskim krvnim pritiskom, ubrzanim radom srca, i konfuzijom. Pacijenti koji do\u0111u u ovu fazu \u010desto su u kriti\u010dnom stanju i potrebna im je intenzivna nega. <\/span><\/p>\n

\u00a0<\/span><\/p>\n

Uzroci<\/span><\/h2>\n

Mezenteri\u010dna ishemija<\/span> arterije obi\u010dno se sre\u0107e kod osoba koje imaju otvrdnu\u0107e arterija koje snabdevaju creva krvlju, a koje se granaju direktno od aorte. Ovo stanje se \u010de\u0161\u0107e javlja kod pu\u0161a\u010da, kod ljudi sa visokim krvnim pritiskom ili kod osoba sa visokim nivoom holesterola u krvi. <\/span><\/p>\n

Mezenteri\u010dna ishemija tako\u0111e mo\u017ee da se javi i kao posledica pojave krvnog ugru\u0161ka, naziva se jo\u0161 \u2018embolus\u2019i iznenada blokira jednu od mezenteri\u010dnih arterija. Ugru\u0161ci obi\u010dno dolaze iz srca ili aorte. Ovi ugru\u0161ci se \u010de\u0161\u0107e sre\u0107u kod ljudi sa poreme\u0107ajima sr\u010danog ritma, poput atrijalne fibrilacije (pretkomorsko treperenje). <\/span><\/p>\n

\u00a0<\/span><\/p>\n

Komplikacije<\/span><\/h2>\n

Najozbiljnija komplikacija mezenteri\u010dne ishemije jeste smrt koja nastupa nakon nedostatka dotoka krvi (infarkta) u crevima.<\/span><\/p>\n
