Shining light on neurovascular disease

Tortuosity and fragility of the intracranial vasculature have precluded the application of novel intravascular imaging modalities during the treatment of cerebrovascular pathologies. In other circulatory beds, these technologies have transformed clinical and therapeutic decision-making. A new report demonstrates the clinical use of high-resolution intravascular imaging in the human cerebrovasculature using neuro optical coherence tomography. This technology provides an unprecedented opportunity to examine the luminal dimensions of cerebrovascular disease. We expect that the neurointerventional community will rapidly adopt this technology-similar to wider adoptions by other vascular specialties-for both a better understanding of underlying disease and clarity of endovascular therapeutic safety and effectiveness.
