Neuroprotective effects of preischemia intraarterial magnesium sulfate in reversible focal cerebral ischemia.

abstract：:In patients with vein of Galen malformations, high-flow shunting decreases cerebral perfusion. By reducing or eliminating these shunts, transarterial embolization can improve cerebral perfusion and clinical outcomes. Quantifying pre- and postembolization shunt blood flow may help determine the optimal timing and effic...
