O malforma\u021bie arteriovenoas\u0103 a creierului ( MAV) este o combina\u021bie de vase de sânge anormale care conecteaz\u0103 arterele \u0219i venele din creier. În timp ce arterele sunt responsabile pentru transportarea sângelui bogat în oxigen de la inim\u0103 la creier \u0219i venele sunt responsabile pentru transportarea sângelui f\u0103r\u0103 oxigen înapoi la pl\u0103mâni \u0219i la inim\u0103, o întrerupere a acestui proces poate avea loc, \u0219i astfel apare un MAV. Aceast\u0103 condi\u021bie este rar\u0103 \u0219i afecteaz\u0103 mai pu\u021bin de un procent din popula\u021bie. O dat\u0103 diagnosticat, un MAV la creier poate fi deseori tratat cu succes pentru a preveni complica\u021biile, precum deteriorarea creierului sau accidentul vascular.<\/p>\n

 <\/p>\n

Simptome<\/h2>\n

O malforma\u021bie arteriovenoas\u0103 a creierului poate s\u0103 nu dea semne sau alte simptome pân\u0103 ce MAV-ul prezint\u0103 o ruptur\u0103, ce duce la sângerarea creierului (hemoragie). În aproape jum\u0103tate din MAV-urile creierului, hemoragia este primul semn.<\/p>\n

Persoanele care nu prezint\u0103 hemoragie de obicei experimenteaz\u0103 urm\u0103toarele simptome cauzate de un MAV al creierului:<\/p>\n

Atac de apoplexie<\/p>\n

Dureri de cap<\/p>\n

Durere ascu\u021bit\u0103 într-o zon\u0103 anumit\u0103 a capului<\/p>\n

Sl\u0103biciune muscular\u0103 sau amor\u021beal\u0103 într-o anumit\u0103 zon\u0103 a corpului<\/p>\n

 <\/p>\n

Semne mai serioase \u0219i simptome pot surveni în func\u021bie de severitatea condi\u021biei individului \u0219i localizarea MAV-ului. Aceste simptome pot include:<\/p>\n

Dureri de cap pulsatile<\/p>\n

Sl\u0103biciune \u0219i amor\u021beal\u0103<\/p>\n

Pierderea func\u021biei mu\u0219chilor<\/p>\n

Vedere deteriorat\u0103<\/p>\n

Vorbire deteriorat\u0103<\/p>\n

Stare confuz\u0103 sau inabilitatea de a în\u021belege<\/p>\n

Instabilitate sever\u0103<\/p>\n

 <\/p>\n

Cauze<\/h2>\n

Cauza MAV-ului la creier este necunoscut\u0103, dar cu toate acestea cercet\u0103torii cred c\u0103 majoritatea MAV-urilor apar ca urmare a dezvolt\u0103rii anormale a vaselor de sânge în timpul dezvolt\u0103rii fetale.<\/p>\n

 <\/p>\n

Factori de risc<\/h2>\n

Orice persoan\u0103 se poate na\u0219te cu un MAV la creier. Cu toate acestea, unii factori pot prezenta un risc mai mare, precum:<\/p>\n

Persoane masculine: MAV-urile sunt mai des întâlnite la persoane de sex masculin<\/p>\n

Istoric familial de MAV: Posibilitatea de mo\u0219tenire a malforma\u021biilor vasculare precum MAV-urile este mai mare<\/p>\n

 <\/p>\n

Complica\u021bii<\/h2>\n

Complica\u021biile unui MAV pot include:<\/p>\n

Reducerea cantit\u0103\u021bii de oxigen pentru \u021besuturile creierului: F\u0103r\u0103 suficient oxigen, \u021besuturile creierului pot sl\u0103bi sau pot muri complet. Acest fapt are drept rezultat simptome asem\u0103n\u0103toare accidentelor vasculare, precum deteriorarea vorbirii, sl\u0103biciunea, amor\u021beala, orbirea, sau instabilitatea sever\u0103.<\/p>\n

Vase de sânge sub\u021biate sau sl\u0103bite: o umfl\u0103tur\u0103 la peretele unui vas de sânge poate ap\u0103rea atunci când se pune presiune asupra sa, astfel cauzând un MAV rupt al creierului.<\/p>\n

Deteriorarea la nivelul creierului: Blocajul lichidelor protectoare la creier.<\/p>\n
