    Ocular blood flow and choroidal thickness changes after carotid artery stenting
    (CONSEL BRASIL OFTALMOLOGIA, 2020) BALTACIOĞLU, FEYYAZ; Biberoglu, Esra; Eraslan, Muhsin; Midi, Ipek; Baltacioglu, Feyyaz; Bitargil, Macit
    Purposes: To evaluate changes in ocular blood flow and subfoveal choroidal thickness in patients with symptomatic carotid artery stenosis after carotid artery stenting. Methods: We included 15 men (mean age, 63.6 +/- 9.1 years) with symptomatic carotid artery stenosis and 18 healthy volunteers (all men; mean age, 63.7 +/- 5.3 years). All participants underwent detailed ophthalmologic examinations including choroidal thickness measurement using enhanced depth-imaging optic coherence tomography. The patients also underwent posterior ciliary artery blood flow measurements using color Doppler ultrasonography before and after carotid artery stenting. Results: Patients lacked ocular ischemic symptoms. Their peak systolic and end-diastolic velocities increased to 10.1 +/- 13.1 (p=0.005) and 3.9 +/- 6.3 (p=0.064) cm/s, respectively, after the procedure. Subfoveal choroidal thicknesses were significantly thinner in patients with carotid artery stenosis than those in the healthy controls (p=0.01). But during the first week post-procedure, the subfoveal choroidal thicknesses increased significantly (p=0.04). The peak systolic velocities of the posterior ciliary arteries increased significantly after carotid artery stenting (p=0.005). We found a significant negative correlation between the mean increase in peak systolic velocity values after treatment and the mean preprocedural subfoveal choroidal thickness in the study group (p=0.025, r=-0.61 7). Conclusions: In patients with carotid artery stenosis, the subfoveal choroid is thinner than that in healthy controls. The subfoveal choroidal thickness increases after carotid artery stenting. Carotid artery stenting treatment increases the blood flow to the posterior ciliary artery, and the preprocedural subfoveal choroidal thickness may be a good predictor of the postprocedural peak systolic velocity of the posterior ciliary artery.

    Neutrophil and lymphocyte ratio in craniocervical artery dissection and prognostic correlations of the blood biomarkers
    (2022-03-01) AKDENİZ, ESRA; ÖMERCİKOĞLU ÖZDEN, HATİCE; BALTACIOĞLU, FEYYAZ; MİDİ, İPEK; MİDİ İ., Ciftci A. C., Ekincikli B. T., AKDENİZ E., ÖMERCİKOĞLU ÖZDEN H., Babashova L., BALTACIOĞLU F.
    Background & Objective: The aim of this study was to investigate the relationship of neutrophil to lymphocyte ratio (NLR) and other blood cells markers in craniocervical artery dissection patients and the dynamic changes of these biomarkers during the disease course, and effects on prognosis of the patients. Method: Cranial MR imaging, cranial and cervical MR angiography and DSA were examined, and diffusion weighted imaging (DWI) was performed to show the acute lesion(s). Results: Forty-six patients with craniocervical artery dissection were included in this study; they had a mean age of 42 years. Almost 60% of the patients (n=27) were admitted during acute state. Almost 2/3 of cases had extracranial dissection (n=31) and nearly 40% of the patients (n=18) had trauma. Neutrophil to lymphocyte ratio (NLR) was observed to be higher in the acute phase of the disease while the ratio decreased in the chronic phase. Low hemoglobin, high lymphocyte and a high NLR were found to have a negative correlation with the National Institutes of Health Stroke Scale (NIHSS). Conclusion: Elevation of neutrophil was higher in acute craniocervical artery dissection as a marker of acute inflammatory response. High NLR, low hemoglobin and high eosinophil levels were associated with worse prognosis and functional outcomes.

    Intraocular Pressure and Retinal Nerve Fibre Layer Thickness Changes After Carotid Artery Stenting
    (TURKISH OPHTHALMOLOGICAL SOC, 2017-08-09) BALTACIOĞLU, FEYYAZ; Biberoglu, Esra; Eraslan, Muhsin; Baltacioglu, Feyyaz; Midi, Ipek
    Objectives: The aim of this study was to evaluate intraocular pressure (IOP) and retinal nerve fiber layer (RNFL) changes in patients with carotid artery stenosis (CAS) after carotid artery stenting. Materials and Methods: This study was conducted as a cross-sectional, non-randomised clinical case series. Fifteen male patients (mean age: 63.6ae9.1) with CAS and more than 70% carotid artery narrowing were included. All of the patients were followed in the department of neurology and were operated in the interventional radiology division. Eighteen healthy male subjects (mean age: 63.7ae5.3) were included in the control group. All of the healthy subjects had a detailed ophthalmological examination and subjects with any chronic eye disease were excluded from the study. All of the participants had a detailed ophthalmological examination including tonometry using Goldmann applanation tonometry and RNFL analysis using optical coherence tomography (RTVue-100 5.1). Results: There were no ocular ischemic symptoms in any of the participants. The mean IOP value was 15.1ae2.1 mmHg in the control group and 16.6ae2.4 mmHg before stent implantation, 16.4ae2.2 mmHg at 1 week after implantation, 16.6ae2.5 mmHg at 1 month after implantation, and 16.7ae2.9 mmHg at 3 months after implantation in the CAS group. Mean RNFL thickness was 105ae6 mu m in the control group; in the CAS group, mean RNFL thickness values were 98ae27 mu m before stent implantation and 103ae11 mu m, 101ae10 mu m, and 101ae11 mu m at 1 week, 1 month, and 3 months after stenting. There were no significant differences between the CAS group and control group regarding IOP and RNFL thickness values (p> 0.05). IOP and RNFL thickness also did not show any statistically significant changes from preoperative measurements in 3 months postoperative follow-up in the CAS group (p> 0.05). Conclusion: IOP and RNFL thickness remained unchanged after carotid stent implantation in carotid artery stenosis patients with no signs of ocular ischemic syndrome.
