Cerecyte Coils in the Treatment of Intracranial Aneurysms: A Preliminary Clinical Study

  		Fig 1. Line drawing of a Cerecyte coil, consisting of a regular bare platinum coil with PGA running through the lumen of the primary platinum wind of the Cerecyte coil (arrows). This also provides stretch resistance when placing coils into the aneurysm. There is some space between the platinum primary winding of the coil for water to pass inside the loops, leading to hydrolysis of the PGA within the coil.

  		Fig 3. Basilar tip aneurysm (A) with a clinical presentation of a subarachnoid hemorrhage, grade II. After treatment, packing attenuation is assessed as moderate, and there is residual filling of contrast medium at the neck initially (B). On follow-up angiography 6 months later, the aneurysm is now completely occluded (C).

  		Fig 4. Anteroposterior angiogram of an incidental carotid T aneurysm (A), which was completely occluded with Cerecyte coils exclusively (B). Six days after treatment, the patient presented with a hypoaesthesia of the right hand. T2-weighted MR image (C) reveals perianeurismal edema with slight mass effect, which was bright on ADC maps (D), indicating vasogenic edema. Symptoms and MR imaging findings completely resolved within 5 days.
