Techniques for Removing Previously Placed Clips

Abstract

We describe techniques for removing previously placed clips. First, the parent artery should be secured to effect proximal flow control. Adherent tissues are dissected by sharp dissecting method using a small knife or microscissors. Then, we open the blade of the clip as little as possible using the clip applier, and the aneurismal clip can be carefully slid out along the line where the clip blade had been. Rough surgical technique might result in rupture of aneurysms. Bypass is also helpful to reduce the risk of ischemia during proximal flow control.
