متن کاملPrediction of portal pressure from intraoperative ultrasonography.

We attempted to evaluate the intraoperative ultrasonography parameters that correlate with portal pressure (PP) in patients undergoing hepatectomy. METHODS We examined 30 patients in whom PP was directly measured during surgery...
