Endovascular arterial occlusion accomplished using microcoils deployed with and without proximal flow arrest: results in 19 patients.

Abstract

In our small series, microcoils were found to be safe and effective for neurovascular occlusion. When both intravenous heparin (5000 U IV bolus) and heparinized catheter flush solutions (5000 U/L) are used, flow arrest during coil placement is unnecessary to prevent clinically apparent embolic complications.
