Radial artery function was studied in 114 consecutive patients by arteriography, Doppler ultrasound flow detection, and physical examination following prolonged (1-10 days) percutaneous cannulation with a single type of 20-gauge catheter. Cannulations lasting 1-3 days produced 11% arterial occlusion, whereas those lasting 4-10 days induced 29% incidence of occlusion (p less than 0.05). In addition, a significantly higher incidence of cannula dysfunction (38% versus 18%, p less than 0.05) and… CONTINUE READING
