Personal profile

Dr. Sviri graduated medical school at the Technion-Israel Institute of Technology. Dr. Sviri did his training in Neurosurgery in Haifa, Israel and did a clinical skull base and cerebrovascular fellowship at the University of Washington, where he is currently affiliated as assistant professor. Dr. Sviri is currently vice chairman in the department of neurosurgery at the Rambam (Maimonides) Health Care Campus in Haifa, Israel. The hospital provides Level I trauma services for more than 2 million north Israel residents. Dr. Sviri holds an appointment as a clinical assistant professor in neurosurgery at the Israel institute of Technology. He joined the Houston Methodist Research Institute Neurosciences Research Program in 2014 as an Assistant Affiliate Member.

Research interests

Dr. Sviri’s research program focuses on clinical evaluation of cerebral blood flow and metabolism in traumatic brain injury and after spontaneous subarachnoid hemorrhage. His current research is focused on defining the relationship between cerebral autoregulation impairments and cerebral metabolism after traumatic brain injury. Dr. Sviri has studied and described the impact of cerebral vasospasm on blood flow to the brain stem and established a new transcranial Doppler grading criteria for posterior circulation vasospasm. Dr. Sviri has also described the appearance of cerebral vasospasm in a new imaging modality – the perfusion CT. The studies on TBI focused on evaluation of the time course for autoregulation recovery after severe traumatic brain injury, suggesting that some patients recovered their autoregulation early and some have a late recovery with an autoregulation paralysis for couple of weeks and more after the injury. Dr. Sviri also found that in severe traumatic brain injury the metabolic rate for oxygen is impaired as some of the patients have mild impairments and those with severe injury lost their ability to extract and to use oxygen.
