Aim: The aim of this study was to evaluate the diagnostic performance of strain ratio elastography in the assessment of retrobulbar orbital fat tissue. Materials and methods: The retrobulbar fat tissue of 14 eyes in 14 participants was scanned by sonoelastography. All the participants had permanent vision loss secondary to glaucoma in at least one eye. The elasticity scores were determined and the strain ratio was based on the comparison of the average strain measured in the retrobulbar fat tissue around the optic nerve at the same depth. Results: The mean strain values for the optic nerve (B) and the retrobulbar fat tissue (A) were 0.78±0.61 and 1.43±0.99, respectively (p=0.005). The mean strain ratio (B/A) was 0.56±0.24. Conclusion: This preliminary study showed that by providing strain values and ratios of different orbital tissues sonoelastography may have a potential use in the diagnosis and follow-up of orbital inflammatory and infiltrative diseases.
AIM: To present our experience on superior cerebellar artery (SCA) aneurysms treated with embolization by using current endovascular techniques. MATERIAL and METHODS: All SCA aneurysms treated by our endovascular team since 2013 were retrospectively evaluated. Clinical information and angiographic findings on presentation, during treatment and on follow-up were noted. RESULTS: Endovascular treatment was the primary treatment method for SCA aneurysms during the study period. Twenty three patients (15 female, 8 male) with a mean age of 50.6 years, 12 of whom with subarachnoid hemorrhage were treated. Treatments included coiling (56%), stent assisted coiling, stentriever assisted coiling, Y stent assisted coiling and flow diversion with either flow diverter placement or telescopic stenting. Two patients died secondary to consequences of subarachnoid hemorrhage. The outcome of 1 patient was Modified Rankin Scale (mRS) 3 and the outcome of remaining 20 patients was mRS 0. The rates of aneurysm occlusion according to Raymond-Roy classification were: class 1 in 11 patients, class 2 in 6 patients and class 3 in 2 patients on a mean follow-up of 15.3 months. Only one patient required retreatment. CONCLUSION: Current endovascular techniques are able to address the high rate of recanalization and retreatment of SCA aneurysms which are currently the major drawbacks associated with primary coiling when compared with surgical treatment. It remains to be shown if use of these latest techniques are associated with increased risk of thromboembolic events.
AIM:To investigate the safety and efficacy of Derivo ® embolisation device (DED), a new-generation flow diverter designed to treat cerebrovascular aneurysms, and its long-term clinical outcomes.
MATERIAL and METHODS:In total, 146 patients with 182 aneurysms were treated with DED. The mean age of the participants was 51.5 years; among them, 46 (31.5%) presented with acute subarachnoid haemorrhage. The mean aneurysm size was 8.3 mm, and 12 aneurysms were involved the vertebrobasilar system. Ophthalmic aneurysms account for most internal carotid artery (ICA) aneurysms.
RESULTS:The Glasgow Coma Scale (GCS) score of 12 patients was <15. DED was associated with a mortality rate of 2.7% and permanent morbidity rate of 3.4%, and a complete aneurysm occlusion rate was achieved in 78.7% of cases after 7.02 months.
CONCLUSION:The DED device is a new-generation flow diverter with excellent opening behaviour and navigational benefits. Our results indicated a safe aneurysm occlusion with optimum morbidity and mortality values despite the fact that almost one-third of the patients presented with subarachnoid haemorrhage.
