A prospective study published online Oct. 8 in Neurosurgery found a handheld near-infrared scanner had 91.2% sensitivity and 50.0% specificity for intracranial hemorrhage in 141 patients with traumatic brain injury. Arissa Medical reported adequate occlusion in 15 of 16 complex brain aneurysms at 12 months with its Syntra device, according to company-reported data.

    In a prospective study published online Oct. 8 in Neurosurgery, 141 patients with mild, moderate or severe traumatic brain injury at two hospitals in Peshawar, Pakistan, had an Infrascanner 2000 examination, a handheld near-infrared device, followed by noncontrast CT. CT confirmed hemorrhage in 125 of 141 patients (88.6%). The device showed sensitivity of 91.2%, specificity of 50.0% and negative predictive value of 42.1%. The authors concluded it may serve as a rapid triage adjunct where CT access is delayed but should not replace CT imaging.

    Arissa Medical announced 12-month results from a prospective, single-arm, nonrandomized pilot study of its Syntra intrasaccular device at Instituto de Neurocirugia Dr Alfonso Asenjo in Santiago, Chile. The company reported a 93.75% rate of adequate aneurysm occlusion, with 15 of 16 patients achieving Raymond-Roy class I or II, and zero device- or procedure-related serious adverse events, according to NeuroNews International. The results are company-reported, and the study remains ongoing, the company said.
