1 A, Depth and angle of the puncture needle entry.
A, Depth and angle of the puncture needle entry. Neuroimages demonstrate CT-guided percutaneous injection of fibrin glue. B, Preoperative CT scans demonstrate a collection of CSF (CT value=12.3) within the cyst. C, Intraoperative CT scans demonstrate the needle placement into the center of the cyst. D, Postoperative CT scans demonstrate hyperattenuated material (CT value=48.5) within the cyst, consistent with aggregated fibrin glue. The CT values before and after fibrin glue placement are shown in B and D. E−F, Pictures of puncture needle (E) and syringe pump system (F) consisting of 2 syringes connected via a connecting stent.
