Abstract
Meticulous dissection to detach an aneurysm from perforating arteries and cranial nerves is often indispensable to achieve complete neck clipping. We report surgical techniques for dissection of an unruptured aneurysm using a pterional approach.
Aneurysmal retraction with a suction tube in an appropriate direction is considered to facilitate dissection of aneurysms. For this purpose, our surgical techniques are summarized as follows: 1) Our “hand-resting” operating style. 2) The use of short-size operating instruments securing meticulous dissection of an aneurysm. 3) Dissection in an appropriate direction derived from both a subfrontal and transsylvian operative field. 4) Mobilization of parent arteries, which is considered to secure aneurysmal retraction.
A wide operative view and steady aneurysmal retraction contribute to the safe dissection and clipping of unruptured aneurysms, preserving the parent arteries and its perforators.
