Outcome of Gamma Knife radiosurgery for trigeminal neuralgia associated with neurovascular compression.

We reviewed 130 patients from 1999 to 2012 to evaluate whether neurovascular compression (NVC) has prognostic value for pain relief in idiopathic trigeminal neuralgia (TN) treated by Gamma Knife radiosurgery (GKRS). Patients were assigned to one of the following groups based on NVC identified by MRI: no NVC, small vessel NVC, and large vessel (defined as part of the vertebrobasilar arterial system) NVC. Follow-up ranged from 4 to 14years.

Effect of Surgecel coverage with topical electrocauterization for preventing and sealing pulmonary air leakage.

Pleural tears usually occur after pneumolysis for dense adhesion or after cone biopsy of lung parenchyma. Repair of the tears is sometimes very difficult. Herein we compared different methods on a pig lung air leak model.
