title: Therapeutic embolization with detachable balloons.
abstract: In our first 18 months' clinical experience with embolization in the chest and abdomen using detachable balloons, successful results were obtained in 34 of 38 patients. One and 2-mm detachable silicone balloons, which can occlude vessels 4--8 mm in diameter, were employed. Prolonged balloon inflation was routinely achieved using iso-osmotic iodipamide meglumine as the filler and limiting inflation volumes to experimentally determined maximums. Improvements in introducer catheter design simplified delivery of the balloon into a variety of circulations. Detachable balloons are not suitable for all embolization purposes, and they are frequently used in conjunction with other agents. When used properly, balloons produce a permanent occlusion that is extremely selective and potentially reversible up to a certain point in the procedure. The balloon technique enables the angiographer to occlude vessels at distances of 2--10 mm beyond the introducer catheter, thus avoiding the need for subselective catheterization and minimizing the dangers of inadvertent embolization.
