Publication Metadata only Risk Factors, Etiological Classification, Topographical Location, and Outcome in Medullary Infarctions(2017-07-01T00:00:00Z) GÖKÇAL, ELİF; Baran, Gode; Niftaliyev, Elvin; GÜZEL, Vildan; ASİL, Talip; GÖKÇAL, ELİF; GÜZEL, VİLDAN; ASİL, TALIPAn understanding of the etiological mechanisms is important for therapeutic decisions and prognostic evaluation of patients with ischemic stroke. The object of this study was to evaluate the risk factors, etiological subtypes, and topography of lesion in patients with medullary infarctions (MIs). Besides, we also investigated early neurological deterioration, new vascular events, and functional outcome of all patients at 3-month follow-up. We analyzed our database consisting of patients who were diagnosed with acute MI and who were admitted within 24 hours of onset. Etiological classification of stroke was made on the basis of the Trial of Org 1972 in Acute Stroke Treatment criteria. All of the infarctions were grouped into anteromedial, anterolateral, lateral, and posterior arterial territories and also categorized into those involving the upper, middle, or lower medulla oblongata. Early neurological deterioration, major vascular events within the first 3 months of follow-up and modified Rankin Score at 3 months were reviewed. A total of 65 patients with medullary infarctions were reviewed. Involved arterial territories differed according to the etiological classification. Large artery atherosclerosis was the most common etiological subtype; however, small vessel disease was the most common subtype in medial MIs. The lesions involving the anteromedial territory were common in the upper medullary region, whereas the lesions involving the posterior and lateral territories were common in the lower medulla oblangata. Recurrent stroke was seen in the posterior and lateral territories; however, early progression and poor functional outcome were mostly seen in lesions involving the anteromedial territories.Publication Open Access Multiple Spontaneous Intracranial-Extracranial Arterial Dissections in a Patient with Osteogenesis Imperfecta(2017-01-01T00:00:00Z) KOLUKISA, MEHMET; GÖKÇAL, ELİF; GÜRSOY, Azize Esra; DENİZ, ÇİĞDEM; ARALAŞMAK, Ayşe; ASİL, Talip; KOLUKISA, MEHMET; GÖKÇAL, ELİF; GÜRSOY, AZIZE ESRA; DENİZ, ÇİĞDEM; ARALAŞMAK, AYŞE; ASİL, TALIPA 40-year-old male with osteogenesis imperfecta (OI) was admitted to the hospital with an acute right monoparesis. Diffusion-weighted MRI showed infarction in the territory of the left anterior cerebral artery (ACA) and in the left posterior cerebral artery (PCA). In his vascular imaging, occlusion of the left vertebral artery (VA) starting from V2 segment was consistent with dissection and pseudoaneurysm in the right ACA. We presented this case because of the presence of spontaneous and simultaneous occurrence of both intracranial and extracranial arterial dissections in OI.Publication Metadata only Progressive deficit in isolated pontine infarction: the association with etiological subtype, lesion topography and outcome(2017-09-01T00:00:00Z) GÖKÇAL, ELİF; Niftaliyev, Elvin; Baran, Gozde; DENİZ, ÇİĞDEM; ASİL, Talip; GÖKÇAL, ELİF; BARAN, GÖZDE; DENİZ, ÇİĞDEM; ASİL, TALIPIt is important to predict progressive deficit (PD) in isolated pontine infarction, a relatively common problem of clinical stroke practice. Traditionally, lacunar infarctions are known with their progressive course. However, few studies have analyzed the branch atheromatous disease subtype as a subtype of lacunar infarction, separately. There are also conflicting results regarding the relationship with the topography of lesion and PD. In this study, we classified etiological subtypes and lesion topography in isolated pontine infarction and aimed to investigate the association of etiological subtypes, lesion topography and clinical outcome with PD. We analyzed demographics, laboratory parameters, and risk factors of 120 patients having isolated pontine infarction and admitted within 24 h retrospectively. PD was defined as an increase in the National Institutes of Health Stroke scale >= 2 units in 5 days after onset. Patients were classified as following: large artery disease (LAA), basilar artery branch disease (BABD) and small vessel disease (SVD). Upper, middle and lower pontine infarcts were identified longitudinally. Functional outcome at 3 months was determined according to modified Rankin scores. Of 120 patients, 41.7% of the patients were classified as BABD, 30.8% as SVD and 27.5% as LAA. 23 patients (19.2%) exhibited PD. PD was significantly more frequent in patient with BABD (p 0.006). PD was numerically higher in patients with lower pontine infarction. PD was associated with BABD and poor functional outcome. It is important to discriminate the BABD neuroradiologically from other stroke subtypes to predict PD which is associated with poor functional outcome in patients with isolated pontine infarctions.
