Overview: BACKGROUND AND OBJECTIVES: Spinal arteriovenous metameric syndrome (SAMS) is a rare, complex vascular disorder characterized by multifocal spinal cord arteriovenous malformations (SCAVMs) affecting structures derived from the same metameric segment. The long-term clinical outcome of SAMS, particularly after embolization, remains poorly understood. This study evaluated the clinical outcomes of embolization for SAMS compared with nonmetameric SCAVMs. METHODS: This retrospective study included 216 patients with intradural SCAVMs who underwent embolization (62 patients with SAMS and 154 patients without metameric background [non-SAMS group]). Clinical and imaging data were reviewed to assess clinical worsening, hemorrhagic events, and angiographic worsening during the observation period after initial embolization. RESULTS: The overall median observation period was 44 months (IQR, 1-307). The SAMS group was associated with a higher…

Summary (Bulgarian)

Това е обобщение за пациенти и специалисти, базирано на официалното резюме в PubMed. Публикацията е в списание Neurosurgery и засяга теми, свързани с гръбначния стълб (диагностика, лечение или епидемиология — според съдържанието на оригиналната статия). Не замества очен преглед при лекар и не представлява персонализиран медицински съвет.
