The use of Teflon as wrapping material in aneurysm surgery.
Even if clipping is the ideal and only complete treatment of the intracranial aneurysm, wrapping is a well-known alternative technique when aneurysm clipping is not feasible, or is not completely satisfactory. We present a technique of wrapping using fibres of Teflon material shaped in strings or in pledgets, arranged on or around the area to be treated and fixed by fibrin glue. This Teflon technique was used during the years 1990 to 1992, in 44 treated aneurysms (33% or all aneurysms treated during the same period), and in 3 situations: 1) to reinforce a residual or additional ectasia next to the clipped aneurysm, usually proximal to the clip (25 cases, i.e., 57%), 2) to treat an arterial ectasia, so called preaneurysmal ectasia, which proved not clippable at surgery (10 cases, 23%) and 3) to protect a nervous or vascular neighbouring structure which was compressed by the clip grip (9 cases, 20%). No complication was noted in relation to this technique. Up to now, no other know wrapping material has received worldwide approval for being completely innocuous and effective. The Teflon material has been widely used in neurosurgical microvascular decompression and in cardiovascular surgery. In these fields, its reliability, safety, and lack of harmful effects have been widely recognized and should also apply in aneurysm surgery. A very long follow-up will be necessary to assess the outcome for this new wrapping technique.
