A simplified technique for ICA back pressures.

Abstract

A single puncture technique is described for measurement of the pressure gradient across the carotid bifurcation as well as the internal carotid artery stump pressure in humans. This technique avoids the cumbersome use of 2 sets of needles and clamps in a small operative field. Potential dangers caused by needle puncture to small arteries, including embolization, intramural hematoma and elevation of the intima are reduced. The possibility of trauma to the vagus, superior laryngeal and anomalous recurrent laryngeal nerves is minimized by this technique.
