Radial Arterial Spasm in Uremic Patients Undergoing Construction of Arteriovenous Hemodialγsis Fistulas: Diagnosis and Prophylaxis with Intravenous Nicardipine

Abstract

Radial arterial spasm in uremic patients undergoing construction of internal arteriovenous (AV) dialysis fistulas was investigated transcutaneously using ultrasonic Doppler flowmetry. In 5 of 15 patients, radial arterial blood flow was significantly decreased 5 min after anastomosing the radial cephalic vein with the radial artery (14.3 ± 4.5%, mean ± SE, of the initial value; p
