Arteriovenozna malformacija (AVM), malformacija mozga, je zam\u0161enost arterija i vena u mozgu ili ki\u010dmenoj mo\u017edini (spinalna arteriovena malformacija).<\/p>\n

U normalnim okolnostima, krv bogata kiseonikom ulazi u mozak kroz arterije, koje se granaju u manje arteriole i jo\u0161 manje krvne sudove (kapilare). Mozak uzima kiseonik iz krvi u kapilarima. Krv bez kiseonika se onda kre\u0107e u male venule a zatim u ve\u0107e vene koje prebacuju krv iz mozga u srce i plu\u0107a.<\/p>\n

Kod Arteriovenozne malformacije, krv se kre\u0107e direktno iz arterija u vene, preska\u010du\u0107i kapilare. Arterije i vene kod AVM-e se mogu probu\u0161iti, izazivaju\u0107i krvarenje u mozgu. Arteriovenozna malformacija se mo\u017ee javiti bilo gde u telu, ali se naj\u010de\u0161\u0107e javlja u mozgu ili ki\u010dmi. I pored toga, AVM-e su retke i zahvataju manje od 1% populacije.<\/p>\n

 <\/p>\n

Simptomi<\/h2>\n

Ovaj poreme\u0107aj ne mora da poka\u017ee bilo kakve simptome sve dok AVM ne pukne, izazivaju\u0107i krvarenje u mozgu (izliv krvi). U vi\u0161e od pola mo\u017edanih malformacija, izliv krvi je prvi znak. Kod ljudi bez izliva krvi, simptomi mogu uklju\u010diti:<\/p>\n

Napade,<\/p>\n

Glavobolju ili bol u jednom delu glave,<\/p>\n

Oslabljenost mi\u0161i\u0107a ili oduzetost jednog dela tela<\/p>\n

 <\/p>\n

Ili neke jo\u0161 ozbiljnije neurolo\u0161ke znake i simptome, u zavisnosti od mesta malformacije, kao \u0161to su:<\/p>\n

Gubitak vida,<\/p>\n

Jaka glavobolja,<\/p>\n

Slabost, utrnulost, ili paralizu,<\/p>\n

Te\u0161ko\u0107e prilikom govora,<\/p>\n

Zbunjenost ili nemogu\u0107nost razumevanja drugih,<\/p>\n

Gubitak ravnote\u017ee<\/p>\n

 <\/p>\n

Uzroci<\/h2>\n

Uzrok AVM-e nije poznat, ali istra\u017eiva\u010di veruju da se javlja jo\u0161 prilikom razvoja fetusa.<\/p>\n

 <\/p>\n

Faktori rizika<\/h2>\n

Bilo ko mo\u017ee biti ro\u0111en sa arteriovenoznom malformacijom mozga, ali ve\u0107i je rizik kod mu\u0161karaca i onih koji imaju istoriju bolesti u porodici.<\/p>\n

 <\/p>\n

Komplikacije<\/h2>\n

Komplikacije kod AVM-e uklju\u010duju:<\/p>\n

Krvarenje u mozgu (izliv krvi u mozak). Arteriovenozna malformacija izaziva prejak pritisak na zidove o\u0161te\u0107enih arterija i vena, \u0161to ih \u010dini tankim i slabim. Ovo mo\u017ee dovesti do bu\u0161enja i oticanja krvi u mozak (izliv krvi).<\/p>\n

Smanjen nivo kiseonika u tkivo mozga. Kod AVM-e, krv preska\u010de splet kapilara i te\u010de direktno iz arterija u vene krv se kre\u0107e brzo kroz tu izmenjenu putanju zato \u0161to ga ne usporavaju kanali manjih krvnih sudova.<\/p>\n

Tanki ili slavi krvni sudovi. ). Arteriovenozna malformacija izaziva prejak pritisak na tanke i slabe\u00a0 zidove krvnih sudova. Izbo\u010denje na zidu krvnog suda (aneurizam) mo\u017ee se javiti i postati podlo\u017ean pucanju.<\/p>\n

O\u0161te\u0107enje mozga. Kako osoba raste, telo mo\u017ee uklju\u010diti vi\u0161e arterija da snabdevaju krv usled AVM-e. Kao rezultat toga, AVM-e mogu postati jo\u0161 ve\u0107e i zauzmu ili potisnu delove mozga. To mo\u017ee da spre\u010di protok za\u0161titnih te\u010dnosti koje slobodno teku kroz hemisfere mozga.<\/p>\n

Ako se te\u010dnost nagomila, mo\u017ee gurnuti tkivo mozga u lobanju. (hidrocefalija).<\/p>\n

 <\/p>\n

Prevencija<\/h2>\n

Ovo je uro\u0111eni poreme\u0107aj i ne mo\u0111e se spre\u010diti.<\/p>\n","protected":false},"author":9,"featured_media":0,"template":"","yoast_head":"\nArteriovenozna malformacija (AVM) - Humanitas.net<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/www.humanitas.net\/sr\/diseases\/arteriovenozna-malformacija-avm\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Arteriovenozna malformacija (AVM) - Humanitas.net\" \/>\n<meta property=\"og:description\" content=\"Arteriovenozna malformacija (AVM), malformacija mozga, je zam\u0161enost arterija i vena u mozgu ili ki\u010dmenoj mo\u017edini (spinalna arteriovena malformacija).
