Introducere. Malformaţiile arteriovenoase cerebrale (MAV) sunt anomalii congenitale cu şunt arteriovenos de mare debit. Riscul anual de re-hemoragie la MAV-uri rupte este estimat la 5-15%. Scop. Rezumatul analizează tehnicile endovasculare moderne în tratamentul MAV cerebrale, cu accent pe strategii complexe şi selecţia pacienţilor, pe baza studiilor recente. Material şi metode. Pentru redactarea acestui rezumat s-a realizat o revizuire sistematică a literaturii din baze oficiale (PubMed, Scopus) pentru perioada 2020-2025, incluzând recenzii, studii de caz şi serii clinice privind embolizarea MAV cerebrale. Au fost analizate tehnici moderne, selecţia pacienţilor, rata de ocluzie, complicaţiile şi rezultatele funcţionale. Rezultate. Abordul transvenos a demonstrat eficienţă în MAV-uri dificil accesibile arterial (cu rate de ocluzie >90%). Concluzii. Tehnicile endovasculare moderne extind opţiunile pentru MAV cerebrale inoperabile. Selecţia meticuloasă a candidatului şi aborduri transvenoase, baloanele de control al fluxului, embolizarea etapizată, navigaţia 3D şi microcateterile cu vârf detaşabil oferă rate de ocluzie de 90-100%,cu morbiditate <5%.
Introduction. Cerebral arteriovenous malformations are congenital anomalies characterized by high-flow arteriovenous shunting. The annual risk of re-bleeding in ruptured AVMs is estimated at 5-15%. Objective. The abstract analyzes modern endovascular techniques in the treatment of cerebral arteriovenous malformations (AVMs), with a focus on complex strategies and patient selection, based on recent studies. Material and methods. A systematic literature review (PubMed, Scopus) was conducted for this abstract, covering 2020-2025, including reviews, case reports, and clinical series on cerebral AVM embolization. Modern techniques, patient selection, occlusion rates, complications, and functional outcomes were analyzed. Results. The transvenous approach has shown high efficacy in AVMs with difficult arterial access (with >90% occlusion rates). Conclusion. Modern endovascular techniques expand treatment options for inoperable cerebral AVMs. Careful patient selection, along with transvenous approaches, flow-control balloons, staged embolization, 3D navigation, and detachable-tip microcatheters, achieve occlusion rates of 90-100%, with morbidity <5%.
