Case Reports
Definitive reconstruction of circumferential, fusiform intracranial aneurysms with the pipeline embolization device.
The Pipeline embolization device (PED; Chestnut Medical, Menlo Park, CA) is a new endovascular construct designed to exclude aneurysms from the parent cerebrovasculature. We report the results of the first two human implantations of this device in North America. ⋯ The PED represents an important advance in the endovascular therapy of cerebral aneurysms, targeting primary parent vessel reconstruction rather than endosaccular occlusion as a means by which to achieve exclusion of the aneurysm and definitive anatomic reconstruction of the parent artery.

To describe a variant of the stent-assisted coiling technique in the endovascular treatment of aneurysms with a dome-to-neck ratio less than 1.5. ⋯ We found that the stentjack technique was helpful in the treatment of selective aneurysms with a dome-to-neck ratio smaller than 1.5.

To provide a comparative description of the endoscopic and microsurgical anatomic features of the blood supply to the cranial nerves in the lateral wall of the cavernous sinus. ⋯ Incorporating the endoscopic and microsurgical perspectives ensures a better understanding of the neurovascular relationships in the cavernous sinus lateral wall. This information could be relevant for preservation of the blood supply to the nerves during surgery in or around the cavernous sinus.

Transnasal endoscopic cranial base surgery is a novel minimal-access method for reaching the midline cranial base. Postoperative cerebrospinal fluid leak remains a persistent challenge. A new method for watertight closure of the anterior cranial base is presented. ⋯ The gasket-seal closure is an effective method for achieving watertight closure of the anterior cranial base after endoscopic intradural surgery.

Self-mutilation is a severe symptom of diseases with varying etiologies. It can be observed in the context of mental retardation and after traumatic brain injury. Pharmacological treatment approaches often prove ineffective. ⋯ This technical case report indicates that deep brain stimulation of the posterior hypothalamus could be a promising approach in the treatment of severe self-mutilating behavior.
