The purpose of this study is to evaluate the role of venous phase timing when compared with technetium-99m Single Photon Emission Computed Tomography (SPECT) during angiographic balloon test occlusion of the internal carotid artery (ICA) and subsequent sacrifice of the ICA. ⋯ Our study demonstrated no correlation between venous phase timing and SPECT. Future studies comparing multiple tests with patients who have had vessel occlusion are necessary to determine the best adjunctive measures to predict delayed ischemia following carotid occlusion.

To assess outcomes after endoscopic endonasal surgery for recurrent or residual pituitary adenomas. ⋯ The endoscopic endonasal approach provides a safe and effective option for recurrent pituitary adenomas. Smaller tumor size, absence of cavernous sinus invasion, and previous microscopic approach were independent predictors of GTR. This finding might suggest that inadequate exposure or limited viewing angle may adversely affect extent of resection in primary microscopic surgeries.

Intracranial arterial atherosclerosis represents a common cause of stroke. Despite aggressive and optimal medical management, many patients will unfortunately suffer additional cerebrovascular events. The role of endovascular intervention for intracranial atherosclerotic disease continues to be uncertain, particularly in regard to extensive, symptomatic stenosis. ⋯ This case illustrates that a long coronary stent might be successfully used to manage extensive intracranial lesions. We also review the efficacy of using 1 very long stent versus multiple overlapping stents, with reference to the coronary angiography literature.

To examine operative findings and outcome of microvascular decompression (MVD) for glossopharyngeal neuralgia (GPN). This research displayed the long-term outcomes of a large series of 35 cases with GPN treated with MVD. ⋯ Classic GPN is usually caused by pulsatile neurovascular compression of the glossopharyngeal and vagus rootlets. MVD is a safe, effective, and durable operation for GPN.

Repeat Intracranial Expansion After Skull Re-Growth in Hyperostotic Disease: A Technical Note.
Camurati-Engelmann disease (CED) is a rare, autosomal-dominant genetic disorder resulting in hyperostosis of the long bones and skull. Patients often develop cranial nerve dysfunction and increased intracranial pressure secondary to stenosis of nerve foramina and hyperostosis. Surgical decompression may provide symptomatic relief in select patients; however, a small number of reports document the recurrence of symptoms due to bony regrowth. We present a patient who had been treated previously with bilateral frontal and parietal craniotomy who experienced recurrence of symptoms due to reossification of her cranial bones. This report underscores the progressive nature of CED and its influence on surgical management. Furthermore, we propose a novel surgical approach with multiple craniectomies and titanium mesh cranioplasties that could potentially offer long-term symptomatic relief. ⋯ Although surgical decompression could provide some patients with CED symptomatic relief, clinicians should consider managing CED as a chronic condition. To the authors' knowledge, this is one of few case reports documenting the recurrence of symptoms in a patient with CED treated by surgical intervention. Furthermore, we propose that multiple craniectomies with titanium mesh cranioplasties confer more permanent symptomatic control, and, more importantly, lower the risk of recurrence secondary to cranial hyperostosis.
