Background: Acquiring proficiency for the repair of a cerebrospinal fluid (CSF) leak is challenging in great part due to its relative rarity, which offers a finite number of training opportunities.

Objective: The purpose of this study was to evaluates the use of a 3-dimensional (3D) printed, anatomically accurate model to simulate CSF leak closure.

Methods: Volunteer participants completed two simulation sessions. Questionnaires to assess their professional qualifications and a standardized 5-point Likert scale to estimate the level of confidence, were completed before and after each session. Participants were also queried on the overall educational utility of the simulation.

Results: Thirteen otolaryngologists and 11 neurosurgeons, met the inclusion criteria. A successful repair of the CSF leak was achieved by 20/24 (83.33%), and 24/24 (100%) during the first and second simulation sessions respectively (average time 04:04 ± 1.39 and 02:10 ± 01:11). during the second session was significantly shorter than the first (p < 0.001). Confidence scores increased across the training sessions (3.3 ± 1.0, before the simulation, 3.7 ± 0.6 after the first simulation, and 4.2 ± 0.4 after the second simulation; p < 0.001). All participants reported an increase in confidence and believed that the model represented a valuable training tool.

Conclusions: Despite significant differences with varying clinical scenarios, 3D printed models for cerebrospinal leak repair offer a feasible simulation for the training of residents and novice surgeons outside the constrictions of a clinical environment.

Emergent Phenol Injection of Bilateral Stellate Ganglion for Management of Refractory Malignant Ventricular Arrhythmias.

Am J Case Rep 2020 Mar 19;21:e921465. Epub 2020 Mar 19.

BACKGROUND Management of incessant electrical storm is poorly defined. These 2 case studies demonstrate a simplified percutaneous approach to achieve stellate ganglion ablation (SGA) and to promptly control malignant ventricular arrhythmias. CASE REPORT This report describes 2 patients with deteriorating hemodynamics, progressive ventricular arrhythmias, and worsening heart failure, managed with emergent percutaneous fluoroscopically-guided bilateral SGA to achieve bilateral cardiac sympathetic denervation. While supine and intubated, the left and then right stellate ganglion were identified guided by anatomic landmarks. Using a 22-guage, 3.5-inch spinal needle, contrast dye was injected with appropriate outline of the stellate ganglion at the uncinate process of the C6 vertebra. Bupivacaine 0.5% was injected, followed by phenol 6%. Successful SGA was confirmed by intentional Horner's syndrome with bilateral eye lag. The procedures were completed in about 30 min without complications and there was a dramatic reduction in ventricular arrhythmias. CONCLUSIONS Emergent percutaneous bilateral SGA can be accomplished with a brief procedure resulting in management of electrical storm.
