3 ONCOTIC ANEURYSMS WITH CEREBRAL INFARCTIONS, CHRONIC ISCHEMIA AND DEVELOPMENT OF SYNANGIOSIS Institute of Neurosurgery Dr. Alfonso Asenjo Santiago. Chile Neuroradiology Department BRAVO E, RIVEROS R, SORDO J, RIVERA R

4 Purpose To present a clinical case with oncotic aneurysms, cerebral infarctions, chronic ischemia and synangiosis.

5 Case Report Female 53 yo Atrial myxoma in 2000 Spontaneus subarachnoid hemorrhage in 2005 Several catheter angiograms with multiple intracranial aneurysms.

6 Multiple Intracranial Aneurysms (2D angiography) Right Internal Carotid Artery AP view Right Internal Carotid Artery Lateral view

7 Multiple Intracranial Aneurysms (2D angiography) Left Internal Carotid Artery AP view Left Internal Carotid Artery Lateral view

8 Multiple Intracranial Aneurysms (2D angiography) Left Vertebral Artery AP view Left Vertebral Artery Lateral view

9 Multiple Intracranial Aneurysms (3D rotational angiography) Right Internal Carotid Artery Left Vertebral Artery

10 Secuelar Brain Lesions (FLAIR) CHRONIC ISCHEMIA?

11 Synangiosis (Catheter Angiogram) Right External Carotid Artery Synangiosis

12 Synangiosis (DynaCT) Right External Carotid Artery Synangiosis

13 Putative Mechanism AJNR Am J Neuroradiol 2001;22:1349-1352 ATRIAL MYXOMA ONCOTIC ANEURYSMS CHRONIC ISCHEMIASYNANGIOSIS

14 Putative Mechanism Neurosci Lett 2006;409:118-123

15 Conclusions This is the first clinical case reporting the presence of multiple oncotic aneurysms, brain ischemia and the development of synangiosis. Chronic ischemia is the trigger for developing synangiosis. Previously, it has been related the presence of myxomatous aneurysms and chronic ischemia. AJNR Am J Neuroradiol 2001;22:1349-1352
