Case ReportsCoil migration after endovascular coil occlusion of internal carotid artery pseudoaneurysms within the sphenoid sinus.
We report two cases of coil migration after endovascular treatment of pseudoaneurysm of the internal carotid artery within the sphenoid sinus with coils and noncovered stents. ⋯ Pseudoaneurysms of the internal carotid artery are a special entity and the environment of the aneurysm within the sphenoid sinus may change over a long time. Coil embolization may lead to the late onset complication of coil migration with the possible risk of acute epistaxis. As a consequence, these patients need a careful and prolonged follow up. FD-CT is an appropriate technique to visualize the implanted coils and if present the migration of coil material.

Case ReportsTechnical considerations of endoscopic septostomy using a biportal approach in a case of hydrocephalus associated with tuberous sclerosis.
We report herein the technical considerations for endoscopic septostomy in a case of hydrocephalus associated with tuberous sclerosis. ⋯ A biportal approach such as the dual endoscopic technique is useful in the treatment of complicated intraventricular lesions with loss of midline structures.

Surgical experience of unilateral laminectomy for bilateral decompression (ULBD) of ossified ligamentum flavum in the thoracic spine.
We describe a new surgical technique for the treatment of ossified ligamentum flavum (OLF) in the thoracic spine through unilateral laminectomy for bilateral decompression (ULBD). ⋯ ULBD is a safe and effective non-fusion technique that provides a good surgically decompressed field. A potential increase in kyphosis following laminectomy can be avoided by this surgical technique, also it preserves the contralateral facet joint, the lamina and the midline ligament structures, while widening the spinal canal.
