Transcutaneous measurement of femoral artery flow
Abstract The measurement of femoral artery blood flow in normal subjects has been accomplished using transcutaneous ultrasonic techniques. The calculation of volume flow depends upon the determination of arterial diameter and mean flow velocity. Arterial dimensions were measured using an echo tracking system which permits identification of the near and far walls of the vessel and its diameter. Flow velocity was measured from the frequency shift that occurs when ultrasound encounters the moving particles in blood. The calculated volume flows agree with those reported using the indicator-dilution methods. The limitations of the present method are discussed.
Introduction ::: The purpose of this study is to compare the tissue incorporation of a novel fenestrated and non-fenestrated crosslinked porcine dermal matrix (CPDM) (CollaMend™, Davol Inc., Warwick, RI) in a porcine model of ventral hernia repair.
