Presentation Transcript

  1. Cristina Caterina Aldea Scientific Coordinator: Professor Ioan Ştefan Florian MD, PhD “Iuliu Haţieganu”University of Medicine and Pharmacy Cluj-Napoca Vascular malformations. General considerations

  2. Non-neoplastic Vascular Malformations of the Brain • Arteriovenous Malformations (AVMs) • Venous Angioma • Cavernoma • Capillary Teleangiectasia • Direct Fistula ( McCormick-1966 )

  3. Arteriovenous Malformations

  4. Arteriovenous Malformations

  5. Patophysiology

  6. Clinical presentation 1. Hemorrhage - most common - 82% significant IP component - SAH, IVH 2. Seizures 3. Mass effect (increased ICP ) 4. Progressive Neurologic Deficit 7% of patients with AVMs present associated aneurysms

  7. Imaging studies • CT scan • CT angiography • MRI / angio - MRI • Cerebral angiography

  8. Cavernomas = cavernous angioma, cavernous hemangioma

  9. Clinical presentation • Seizures • Progressive Neurological Deficit • Hemorrhage ( usually IP ) > 50 % asymptomatic

  10. Imaging Studies • CT • MRI - hemosiderine ring( “salt and pepper” appearance ) • Angiography – “angiographically occult”

  11. Thank you for your attention!
