On the basis of recent findings about the pathophysiology of cluster headache and through the experience reported in recent literature, we have reviewed the outcome of four patients affected by drug-resistant cluster headache treated in our department by posterior hypothalamic deep brain stimulation with a follow-up of more than 5 years. ⋯ The long-lasting pain reduction and the improvement in the patients' symptoms should be considered a real positive prospective, not only because there was uncertainty about the persistence of the beneficial effects at a long-term follow-up, but also for the improvement of the quality of life. The stimulation can restore important aspects concerning the psychic condition that very often constitutes an important limiting factor in normal daily life for this type of patient.

Cerebrospinal fluid leakage and meningitis caused by frontal sinus (FS) exposure are characteristic complications of bifrontal craniotomy used for treating skull base tumors and anterior communicating artery aneurysms. Prevention of these complications is of utmost importance. We describe in detail our procedure for sealing exposed FSs during bifrontal craniotomy and present the results and outcomes of the procedure. ⋯ Our results indicate the effectiveness of our technique in the prevention of FS-related postoperative complications.

To provide an incidence and descriptive evaluation of kinking of the internal carotid artery (ICA) after carotid endarterectomy (CEA) in a consecutive CEA series that included the use of intraoperative duplex ultrasonography (IDUS) monitoring and to determine the effect of kink patch repair on long-term postoperative ICA restenosis. ⋯ ICA kinking stenosis after CEA was a common finding in this CEA series. Because of their unique anatomic and hemodynamic properties, the identification and assessment of kinks after CEA required the use of IDUS monitoring. A selective patch closure method for kinked vessels with peak systolic velocities of ≥ 120 cm/second identified by IDUS was effective in resolving hemodynamically significant stenosis and minimizing long-term postoperative restenosis.
