Dorsal internal carotid artery (ICA) aneurysms are notorious for their high morbidity and mortality. They have an extremely fragile wall and have a high chance of rupture and clip slippage during the intraoperative and postoperative period. Strategies proposed to mitigate these problems encompass including part of the normal ICA wall in addition to neck of aneurysm in clip blades, as well as the use of encircling materials (silicon, cellulose, Weck's clip) over a clip. The Achilles' heel of the problem is to take an appropriate thickness of the normal ICA in clip blades. Too less or too much of this can spell disaster. This is easier said than done during an actual surgical procedure. So, in this difficult situation, is there any better method of clipping? We propose a fenestrated clip in which the clip blades are placed just at the beginning of fenestration and at right angles to the clip. This occludes the aneurysm taking part of the normal ICA wall in the clip blades. The fenestration hugs the ICA and prevents clip slippage. This has been explained with appropriate figures in the two and three-dimensional format. There cannot be a single stop solution for a complex disease like dorsal ICA aneurysm. The present proposed design is an attempt to provide a better clipping chance in these difficult aneurysms. Future work on this design can prove its usefulness.
