- W1576128548 abstract "OBJECTIVE: To report clinical and radiologic features of intracranial arterial dissections (IAD). BACKGROUND: The absence of external elastic lamina with a thin muscular layer and adventitia predispose to IAD. The frequency and pattern of IAD is unknown in Argentina. We report a single institution series of IAD from Buenos Aires, Argentina. DESIGN/METHODS: Data was retrospectively obtained from the FLENI Stroke Data Bank between 1994 and 2013. We assessed demographic characteristics, clinical presentation, diagnostic tests, acute treatment, and outcome at six months. RESULTS: Of 297 patients with cerebral arterial dissections (CAD), 117 (39%) were extracranial artery dissections (EAD), 97 (33%) were EAD/ IAD, and 83 (28%) were IAD. Mean age for IAD was 44±12 years, and 63% were men. Clinical presentation was: ischemic stroke (71%), pain/Horner/tinnitus (21%), transient ischemic attack (4%), and hemorrhagic stroke (4%).Diagnosis was made by MRI, angio-TC, ultrasound and/or digital subtraction angiography. The most frequent patterns were: stenosis (71%), occlusion (13%), dissection flap (7%), and dissecting aneurysm (8%). Patients were treated with antiaggregants (50%), anticoagulants (46%), r-TPA (2%), surgery (1%) or no treatment (1%).At six-months follow up, 63% of the patients had a mRS 0/1, 32% of 2/3, and 4% of 4/5. One patient died during follow up (1%) CONCLUSIONS: IAD represent a substantial proportion of CAD and may be a frequently underdiagnosed cause of stroke. Intraparenchymal hemorrhage seemed to occur less frequently in our series than previously reported. Study Supported by: Disclosure: Dr. Dossi has nothing to disclose.
