Large‐Vessel Occlusion Art by Sebastian Sanchez, MD

Hopefully your competent? doctor can show you an EXACT PICTURE of your stroke damage and EXACTLY describe the areas and functions it compromised and then the EXACT PROTOCOLS to fix the problems caused by this! Well if you have a competent doctor that can be done. But I bet you don't have a competent doctor!

About the Artist

Sebastian Sanchez is a neurology resident at Yale University. Before commencing his residency, he dedicated 2 years to research as a fellow under the mentorship of Dr Edgar Samaniego at the University of Iowa. During this tenure, he delved into a spectrum of subjects encompassing stroke and intracranial aneurysms.

About the Art

By unveiling intricate cerebral blood flow dynamics, perfusion imaging is a useful tool for clinical decisions in stroke management. It precisely maps the ischemic penumbra and core infarct zones, guiding interventions like endovascular thrombectomy. In large‐vessel occlusion, rapid changes manifest as color variations on perfusion imaging, indicating reduced regional blood flow. This Photoshop‐rendered watercolor, based on perfusion imaging, vividly portrays the evolving impact of a large‐vessel occlusion affecting the M1 segment of the middle cerebral artery. As the blood flow is compromised, the colors in the heat map progress from blue into green, yellow, and red. A representation of the brain's vasculature is superimposed, abruptly interrupted on the observer's right by the occlusion, exemplifying the profound disruption caused by vascular blockages.
