    Simultaneous balloon angioplasty and stent implantation in supraaortic multiple stenosis
    (2020) Gunesli, Aylin; Akgul, Erol
    Purpose: The aim of this study was to evaluate the success and complications of endovascular treatment in supraaortic multiple stenotic lesions Materials and Methods: The study was planned as a retrospectively. The records of patients who underwent percutaneous interventional treatment for multiple stenosis in the supraaortic vessels between January 1, 2004 and December 31, 2009 were reviewed. Percutaneous endovascular intervention was decided with doppler ultrasonography, magnetic resonance imaging, computed tomography or digital subtraction angiography provided that more than 50% stenosis was detected in the supraaortic vessels. Patients with at least 2 severe stenosis who underwent multiple interventional procedures in one session were included in the study. Results: A total of 34 patients (mean age 60.4 +/- 12.5 years and 6 female (17.4%)) were included in the study. A total of 74 lesions were treated in 34 patients. Stents were used in all procedures. No mortality or serious morbidity was observed during follow-up. The technical success of the procedure was 100%. Restenosis was observed in 4 patients (11.7%) at a mean follow-up of 29.5 +/- 18.3 months. Three of these patients were re-treated. Conclusion: According to the results of our study, endovascular intervention can be safely performed in occlusive atherosclerotic vascular disease of the supraaortic branches. Mortality and morbidity of this treatment is very low. In patients with restenosis during follow-up, re-intervention can be performed safely. If multiple lesions are present in the same patient group, multiple interventions are a safe treatment option.

    Evaluation of the Ophtalmic Artery Flow Pattern with Color-Doppler Ultrasonography in the Patients with Carotid Artery Stenosis
    (2015) Demir, Senay; Akgul, Erol; Aikimbaev, Kairgeldy; Tokmak, Naime; Inal, Mehmet; Aksungur, Erol
    Purpose: To assess whether ophtalmic artery flow patterns reflect the status of cerebral circulation in patients with carotid artery stenosis. Material and Method: Twenty-four patients including 14 men and 10 women, with varying degrees of monolateral or bilateral carotid artery stenosis were included in the study. Patients' ages ranged between 32 and 79 years (mean 60). The control group was composed of 12 subjects without carotid artery stenosis who had undergone digital substaction angiography for different purposes. Digital substraction angiography and color-Doppler ultrasonography were performed in all the patients and the control group. Degrees of carotid artery stenosis and flow patterns and velocities, pulsatility and resistance indices of ophtalmic arteries of two groups were compared. Results: Significant differences in ophtalmic artery flow patterns and velocities, pulsatility and resistance indices between those patients with carotid artery stenosis of more than 70% and the control group were recorded. Conclusion: Imaging of the ophtalmic artery with color-Doppler ultrasonography is a useful and cost-effective method that reflects the status of cerebral circulation in patients with carotid artery stenosis.
