Review Case Reports
Ruptured spinal artery aneurysm associated with coarctation of the aorta.
Spinal artery aneurysms associated with aortic coarctation are exceptionally rare, with only eight cases reported in the literature that we are aware of, and treatment of the aneurysm described only in one of them. Aortic coarctation often results in an aberrant collateral circulation with hyperdynamic flow and potential spinal artery aneurysm formation, growth, and rupture. Microsurgical, interventional, and medical management of these lesions can be challenging and has rarely been reported. Complication avoidance requires thorough knowledge of the clinical presentation of the disease, the hemodynamic factors involved, and the therapeutic tools available. ⋯ Spinal artery aneurysms induced by aortic coarctation are rare and complex entities. They pose unique surgical and medical challenges. Securing the aneurysm should be prioritized specifically in cases of subarachnoid hemorrhage. Blood pressure should be closely monitored and balanced to reduce the risk of rehemorrhage and at the same time allow for sufficient end-organ perfusion.

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.
