Supradiaphragmatic hematoma is a type of hematoma that occurs after transsphenoidal (TS) resection of pituitary adenoma and requires special management. ⋯ Supradiaphragmatic hematoma can be clinically and radiologically distinguished from other types of hematoma occurring after TS resection of pituitary adenoma. Transcranial surgery should be performed to manage supradiaphragmatic hematoma, when symptomatic. Insertion of an EVD at the time of evacuation is mandatory to relax the brain and to alleviate the hydrocephalus.

Many new endovascular devices have been used under the guidance of the International Subarachnoid Aneurysm Trial. Clipping still offers higher occlusion rates, and its technique continues to evolve, resulting in smaller exposures and reduced manipulation to brain tissue. We sought to evaluate the routine use of the minisphenoidal approach to manage intracranial aneurysms in a high-volume institution. ⋯ Evolution of endovascular techniques has paved the way for minimizing surgical exposures. Routine use of the minisphenoidal approach for managing ruptured, unruptured, and previously coiled aneurysms is safe and provides adequate exposure with robust occlusion rates.

No clear consensus yet defines the endpoints for operative learning curves in the transition to minimally invasive endoscopic techniques. This retrospective review of our first 202 patients who underwent endoscopic pituitary resection examines the statistical learning curve related to operative times-a measure of our surgical team's efficiency and complication rate, a reflection of surgical skill and maturity. ⋯ Our learning curve-defined endpoints for 2 measures, operative time and complication rates, support improved outcomes for reduced CSF leaks, the most common complication, with increasing operative experience. We will continue to examine the implications related to safety, efficacy, and the need for subspecialization in this minimally invasive surgery.

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.

Oblique lumbar interbody fusion is a commonly used surgical method of achieving lumbar interbody fusion. There have been some reports about complications of oblique lumbar interbody fusion at the L2-L3 level. However, to our knowledge, there have been no reports about ureter injury during oblique lumbar interbody fusion. We report a case of ureter injury during oblique lumbar interbody fusion to share our experience. ⋯ Our study shows that a low threshold of suspicion of ureter injury and careful manipulation of retroperitoneal fat can be helpful to prevent ureter injury during oblique lumbar interbody fusion at the upper level.
