Arteriyovenöz Malformasyonlar
Özet
Serebral arteriyovenöz malformasyonlar, normal kılcal damar ağı olmaksızın arterler ve venler arasında doğrudan bağlantı kuran anormal damar yumaklarıdır. Genellikle intrakraniyal kanama ve nöbetlerle ortaya çıkan bu yapıların tanısı beyin görüntüleme yöntemleriyle konulur. Tedavi süreçleri, lezyonun boyutu ve konumuna göre mikrocerrahi, embolizasyon veya radyocerrahi gibi yöntemlerin tek başına veya kombinasyon halinde uygulanmasını içerir. Bu vasküler lezyonlar gelişimsel süreçteki bozukluklardan kaynaklanmakta olup, özellikle genç yetişkinlerde klinik tabloya neden olmaktadır.
Cerebral arteriovenous malformations are abnormal clusters of vessels that create direct connections between arteries and veins without an intervening capillary network. These structures, which typically present with intracranial hemorrhage and seizures, are diagnosed primarily through brain imaging techniques. Treatment strategies involve the application of microsurgery, embolization, or radiosurgery, either alone or in combination, depending on the lesion's size and location. These vascular lesions result from developmental abnormalities and predominantly manifest in young adults.
