How I do it: direct pressure measurement in moyamoya bypass.

ABSTRACT

BACKGROUND: The direct quantitative measurement of donor and recipient pressures in patients with moyamoya vasculopathy (MMV) during superficial temporal artery-middle cerebral artery (STA-MCA) bypass surgery has yet to be reported in academic literature. METHOD: Using a wireless pressure wire, we describe our approach to measuring seven pressure parameters in MMV patients step-by-step. CONCLUSION: Direct intraluminal pressure measurement of donor and recipient arteries provides a practical and accurate means to quantify cerebral hemodynamic parameters in MMV patients, enhancing understanding of individualized hemodynamic changes pre- and post-surgery.
