Prevalence of Neurovascular Pathologies: A Study on the First 18 Months Activity of Firoozgar Hospital

Background and Aim: Endovascular neurosurgery is widely accepted as a useful modality for the management of neurovascular disorders. This retrospective study aimed to evaluate the causes of diagnostic and therapeutic neuroendovascular procedures, as well as the prevalence, type, location and management of vascular pathologies observed in Firoozgar Hospital, Tehran City, Iran. Methods and Materials/ Patients: In this study, we analyzed the causes and outcomes of the neuroendovascular procedures during 18 months from February 2013 to September 2014 in Firoozgar Hospital, Tehran, Iran. Results: In total, 724 diagnostics and therapeutic neuroendovascular procedures were performed on 561 patients. The mean (SD) age of the patients was 44.83(18.73) years and 598(50.27%) of them were females. The most prevalent cause of these procedures was cryptogenic intracranial hemorrhages (24.58%), followed by ruling out vascular lesions  due to suspicious MRI without neurological defects (14.91%), and suspicious MRI with focal neurologic defects (11.74%).  Conclusion: Endovascular neurosurgery plays a key role in diagnosis and treatment of the most prevalent neurovascular disorders in our referral center.
