The Doppler flowmeter as an aid in the diagnosis of the hyperstomy syndrome

A new aid in the diagnosis of the hyperstomy syndrome by non-invasive procedure using the Doppler flowmeter is presented. Several studies prove that there is an increased venous saturation and increased venous pressure in the hyperstomy syndrome, i.e., various degrees of arterialization of the venous system as well as an increase in the venous flow. Based on these studies the authors detected changes of this flow with the Doppler flowmeter interpreted as being the results of the activation of arteriolo-venular communications. In addition, in the first ten cases in which these have been found, serial arteriography confirmed the diagnosis of hyperstomy syndrome.
