As defective balloons often lead to disasters, reliable detachable balloons have long been eagerly awaited. We had the opportunity of using ITC detachable balloons on 30 cases with various neurovascular diseases. No defective balloon was found during in vitro testing done immediately prior to their placement in the patient's vascular system. Moreover, there was no premature detachment during catheter manipulation or early deflation within several weeks after detachment. Both immediate and long term follow up showed balloon embolization would be the first choice for various direct arteriovenous fistulae. Also, anatomically inaccessible aneurysms with small necks, less than 1 cc in volume, could be successfully treated by detachable balloons. However, detachable balloons are not ideal embolic material for large and giant aneurysms. In conclusion, when used by properly trained personnel, ITC silastic detachable balloons are a safe, easy to use and reliable option.
