First impressions about Adherus, a new dural sealant.

PURPOSE: The aim of the study is to report our first impressions about Adherus, a novel dural sealant, used in neurosurgical endoscopic transnasal procedures. METHODS: We retrospectively reviewed the clinical and surgical records of the first 11 patients with intraoperative high-flow cerebrospinal fluid leak treated with the aid of Adherus at our center between February and October 2014. The healing at the level of the dural plasty was monitored and evaluated radiologically and with regular endoscopic inspections. RESULTS: With a median follow-up of 210 days, no postoperative CSF leak or surgical site infections were found in any of the cases. CONCLUSIONS: Based on our preliminary experience, this new dural sealant seems to provide an effective aid in dural plasty during endoscopic transphenoidal procedures.

Haemorrhagic presentation of a craniopharyngioma in a pregnant woman.

Objective. Craniopharyngioma is a rare tumour, and, consequently, acute clinical presentation and diagnosis, during pregnancy, of this pathology are quite difficult to find. Only few cases are reported in the literature, and no one describes these two conditions in association. Methods. We report a particular case of craniopharyngioma presenting both of the above conditions. Results. The patient was successfully operated with endoscopic technique. Conclusions. Rare and difficult cases, created by the superposition of different clinical conditions, need multidisciplinary management, with collaboration, integration, and cooperation between different medical specialists.

Treatment of high-grade spondylolisthesis with Schanz recoil screws: our experience.

PURPOSE: Spondylolisthesis surgical treatment is often difficult with higher degree of slip and related techniques still debated. We have taken into consideration double thread recoil Schanz screws. This system should allow the best reduction of the slip, treating only the affected vertebrae. METHODS: We retrospectively analyzed 46 patients affected by grade II or higher spondylolisthesis, treated with circumferential arthrodesis using Schanz screws. Duration of surgery, complications, reduction, and rate of fusion have been recorded. RESULTS: We found that duration of surgery and complications were similar or slightly lower if compared to our standard Posterior Lumbar Interbody Fusion procedures. However, radiological results and clinical outcome appear better in cases treated with Schanz screws. CONCLUSIONS: Fixation system with Schanz screws seems to be effective in reducing the slip, treating only the affected level, in high grade of spondylolisthesis.
