Review Case Reports Comparative Study
Intraventricular vs intrathecal baclofen for secondary dystonia: a comparison of complications.
Intrathecal baclofen (ITB) is an effective treatment for secondary dystonia. However, in many patients with dystonia, placement of an intrathecal catheter is difficult because of anatomic anomalies or spinal fusion. Intraventricular baclofen (IVB) has been shown to be an effective alternate route for drug delivery in a small series of patients. ⋯ This study shows that IVB is as safe as ITB. There may be a lower risk of catheter or leak-related complications with IVB, although this study was too small to show significance.

Review Case Reports
Optimal surgical approaches for Rathke cleft cyst with consideration of endocrine function.
Surgical indications for Rathke cleft cyst are not clear. ⋯ Minimal incision with radical removal of cyst content is reasonable to prevent the development of endocrine disturbances and other complications. Individualized risks and benefits must be assessed before a decision is reached regarding surgery and surgical method. Patients with recurrent Rathke cleft cyst require careful follow-up with special attention rather than a hasty operation.

Traumatic brain injury has long been associated with abnormal coagulation parameters, but the exact mechanisms underlying this phenomenon are poorly understood. Coagulopathy after traumatic brain injury includes hypercoagulable and hypocoagulable states that can lead to secondary injury by either the induction of microthrombosis or the progression of hemorrhagic brain lesions. ⋯ The goal of this review is to summarize the current knowledge regarding the mechanisms of coagulopathy after blunt traumatic brain injury. The current and emerging diagnostic tools, radiological findings, treatment options, and prognosis are discussed.

Surgical clipping with complete occlusion of the aneurysm and preservation of parent, branching, and perforating vessels remains the most definitive treatment for intracranial aneurysms. ⋯ Endoscopic enhancement of the visual field provided by the endoscope before, during, and after microsurgical aneurysm occlusion may be a safe and effective application to increase the quality of treatment. Although unexpected findings concerning completeness of aneurysm occlusion and compromise of involved vessels could be diminished by endoscopic assessment, total prevention was not accomplished.

Review Case Reports
Flash fluorescence with indocyanine green videoangiography to identify the recipient artery for bypass with distal middle cerebral artery aneurysms: operative technique.
Distal middle cerebral artery (MCA) aneurysms frequently have nonsaccular morphology that necessitates trapping and bypass. Bypasses can be difficult because efferent arteries lie deep in the opercular cleft and may not be easily identifiable. ⋯ The flash fluorescence technique provides quick, reliable localization of an appropriate recipient artery for bypass when revascularization is needed for a distal MCA aneurysm. This technique eliminates the need for extensive dissection of the efferent artery and enables a superficial recipient site that makes the anastomosis safer, faster, and less demanding.
