Publication Metadata only Evaluation of cerebral hemodynamic status in patients with unilateral symptomatic carotid artery stenosis during motor tasks, through use of transcranial Doppler sonography(2022-04-01T00:00:00Z) Milanlıoğlu, Aysel; YAMAN KULA, ASLI; KOLUKISA, MEHMET; ASİL, Talip; YAMAN KULA, ASLI; KOLUKISA, MEHMET; ASİL, TALIPBackground: Carotid artery stenosis increases cerebral ischemic event risk through changing different cerebral hemodynamic parameters. Objective: To investigate how cerebral hemodynamics in the M1 segment of middle cerebral artery change in patients with carotid artery stenosis, after motor tasks using transcranial Doppler sonography (TCD). Methods: Thirty-two healthy subjects and 30 patients with unilateral symptomatic carotid artery stenosis were recruited. The patient population was divided into three groups according to the degree of stenosis (group 1: ≥50 to 69%, group 2: 70 to 89% and group 3: ≥90 to 99%). TCD was used to measure the pulsatility index (PI) and cerebral vasomotor reactivity (CVR). Results: In the patient group, significant differences for symptomatic side PI values (p=0.01) and mean CVR increases (p=0.05) were observed, compared with the healthy controls. However, the difference was not statistically significant for asymptomatic side PI values and mean CVR increases. The results from the intergroup comparison showed significantly higher percentages of symptomatic and asymptomatic side CVR increases in group 1, compared with groups 2 and 3 (p=0.001 and p=0.002, respectively). Conclusions: Our study showed that cerebral autoregulation and hemodynamic mechanisms are impaired in patients with carotid artery stenosis. Furthermore, the impairment of PI and CVR tends to get worse with increasing degrees of stenosis. In addition, this study demonstrated that assessment of these two hemodynamic parameters in clinical practice might be helpful for monitoring the progress of carotid artery stenosis.Publication Open Access Endovascular Therapy of Acute Ischemic Stroke by Interventional Cardiologists: National Initial Experience(2013-10-29) TASAL, Abdurrahman; Bacaksiz, AHMET; VATANKULU, Mehmet Akif; SONMEZ, Osman; TURFAN, Murat; ERDOGAN, Ercan; KARADELI, Hasan Huseyin; Kolukisa, MEHMET; KUL, Seref; ALTINTAS, Ozge; Asil, TALİP; GOKTEKIN, Omer; BACAKSIZ, AHMET; KOLUKISA, MEHMET; ASİL, TALIPObjectives: We report our initial experience with thrombectomy devices in patients with acute ischemic stroke. Study design: Demographic, clinical, and angiographic findings of 19 consecutive patients (7 females and 12 males; mean age 61.4±12.5 years) with acute ischemic stroke were evaluated retrospectively. Results: The mean initial National Institutes of Health Stroke Scale (NIHSS) score was 19.5±5.6. Middle cerebral artery was the occluded artery in all of the patients (proximal occlusion in 11, distal in 8 and tandem occlusions in 7 patients). Successful revascularization was achieved in 16 patients (84%). The mean NIHSS score was 8.4±8.2 at 24 hours after the procedure, and 60% of patients showed a modified Rankin scale score of ≤2 at 90 days. New occlusion by migrated emboli was observed in 2 (11%) cases. None of the patients had experienced post-procedural symptomatic intracerebral hemorrhage; 3 patients died during the three-month follow-up. In all patients, thrombectomy was performed with retrievable Solitaire AB stent system. Conclusion: This single-center experience with mechanical thrombectomy devices demonstrated that high success rates can be achieved by experienced interventional cardiologists in equipped cath labs throughout the country.Publication Open Access One-year follow-up in patients with brainstem infarction due to large-artery atherothrombosis(2015-01-01) Kolukisa, MEHMET; GUELTEKIN, Tugce Ozdemir; BARAN, Gozde Eryigit; Aralasmak, AYŞE; KOCAMAN, Guelsen; GUERSOY, Azize Esra; Asil, TALİP; KOLUKISA, MEHMET; ARALAŞMAK, AYŞE; GÜRSOY, AZIZE ESRA; ASİL, TALIPBackground: Posterior circulation infarction accounts for approximately 25% of the ischemic strokes. A number of different conditions may be associated with the development of brainstem infarction. Prognosis and recurrence rate of brainstem infarction due to large-artery atherothrombosis is still controversial. Methods: A total of 826 patients with ischemic stroke were admitted to our clinic during a 15-month period. Patients with clinical and radiological evidence of brainstem infarction were comprehensively assessed with appropriate vascular imaging modalities and for cardiological causes. Subjects with an established diagnosis of large-artery atherothrombosis were followed up for 1 year in terms of prognosis and recurrence rates. Results: Of the 101 patients with an established brainstem infarction, the diagnostic work-up indicated the presence of large-artery atherothrombosis as the causative factor in 53. A recurrent stroke was detected in the posterior circulation within the first 3 months in 5.8% and within 1 year in 9.8% of these individuals. The 1-year mortality rate was 11.7%. All patients with recurrent stroke had intracranial vascular narrowing at baseline. Conclusion: Our findings demonstrate a particularly high rate of recurrence and mortality at 1 year among patients who have a brainstem infarction due to intracranial arterial stenosis.

Although DSA (digital substraction angiography) is regarded as the gold standard, noninvasive methods of CT, CTA and MRI, MRA are widely used for diagnosis. Aim: Our aim is to illustrate noninvasive imaging findings in CCD. Conclusion: Emphasizing on diagnostic pitfalls, limitations and mimicking diseases.
