Persistent idiopathic facial pain (PIFP) can be refractory to conventional management approaches. Neuromodulatory procedures such as percutaneous trigeminal nerve stimulation (TNS) have been sparsely reported as potential treatment options for amelioration of debilitating refractory pain associated with PIFP. The present study investigated the use of percutaneous TNS in a series of patients with PIFP to evaluate the potential efficacy of pain relief. ⋯ The results from the present study have indicated that percutaneous stimulation of the trigeminal nerve is efficacious in the treatment of PIFP and can significantly decrease morphine equivalent use. Further longitudinal studies are required to validate our results.

Dural arteriovenous fistulas (DAVFs) with perimedullary venous drainage are very rare intracranial DAVFs. Treating DAVF via an endovascular electrocoagulation technique, to the best of our knowledge, has not been reported in the literature. We therefore report the first successful case. ⋯ The endovascular electrocoagulation technique is very effective in the management of complex DAVFs with perimedullary venous drainage.

Stereotactic needle biopsy provides a minimally invasive option for the diagnosis of intracranial lesions but is limited by inconclusive diagnoses on frozen pathology. For rapid pathology, 5-aminovelunic acid and sodium fluorescein have previously demonstrated potential as diagnostic adjuvants. Stereotactic biopsy with near-infrared (NIR) fluorophores has not been reported. We identified 5 representative cases using NIR fluorescent dye indocyanine green (ICG) administered in a high dose, delayed manner. ⋯ SWIG provides rapid intraoperative confirmation of pathologic brain tissue by permeating neoplastic or inflammatory brain tissue via a mechanism similar to that of gadolinium enhancement. SWIG-guided stereotactic biopsy can improve surgical efficiency by enhancing confidence in acquisition of target tissue.

Wrap-clipping is one of the recommended treatments for ruptured blood blister-like aneurysms (BBAs) of the internal carotid artery (ICA). However, the long-term clinical and angiographic outcomes of this procedure have not yet been elucidated. The present study examined the long-term efficacy of wrap-clipping using a polytetrafluoroethylene membrane, an ideal wrapping material, for BBAs. ⋯ Wrap-clipping using a polytetrafluoroethylene membrane for ruptured BBAs is a useful and acceptable procedure with long-term effectiveness. The effectiveness of this method can be ensured using modern monitoring methods.

To evaluate values of cerebrospinal fluid (CSF) and serum procalcitonin (PCT) for diagnosis of intracranial infection after craniotomy and relationship between them and to explore value of PCT in guiding clinical use of antibiotics. ⋯ CSF PCT is a good marker for intracranial infection and could be used to help confirm intracranial infection and provide guidance for clinical use of antibiotics when combined with serum PCT.
