Why is the inflation process of a cutting balloon typically done slowly?

The inflation process of a cutting balloon is typically done slowly to avoid damage to the vessel intima. This is crucial in interventional radiology because the intima, which is the innermost layer of the blood vessel, is delicate. If the balloon is inflated too quickly or at excessively high pressures, it can cause lacerations or other trauma to this layer. By inflating the balloon slowly, operators can monitor the effects on the vessel and ensure that the procedure is performed safely, minimizing the risk of complications such as dissection or perforation.

While maintaining a steady pressure level, allowing for proper visualization, and facilitating quicker recovery of the vessel are also important in interventional procedures, they do not directly pertain to the specific reason for a slow inflation process with a cutting balloon. The primary concern remains the preservation of vessel integrity during the procedure.
