The insular cortex is more susceptible to ischemia following MCA occlusion than other portions of the MCA territory because it has the least potential for collateral supply from the anterior cerebral and posterior cerebral arteries. loss_of_the_insular_ribbon_sign.txt Last modified: 2024/06/07 03:00by 127.0.0.1
