Fig. 2From: Comparison between intracranial collaterals and cerebral hemodynamics in patients with extracranial carotid stenosis versus combined extra- and intracranial stenosis using transcranial duplexDifference in mRS in both groups. Those 15 patients with extracranial stenosis showed less mRS both upon discharge with mean 2.067 ± 1.033 and after 3 months with mean 1.200 ± 0.941 than those 15 patients with both intracranial and extracranial stenosis both upon discharge with mean 2.800 ± 0.862 and after 3 months with mean 2.933 ± 1.534. Consequently, the first group with only extracranial stenosis showed more significant improvement than the second groupBack to article page
