Extradural transcavernous approach to cavernous sinus cavernous hemangiomas.

Objective: Cavernous sinus cavernous hemangioma (CSCH) is a rare extra-axial vascular lesion and is difficult to be removed due to their location, propensity for profuse bleeding during surgery, and relationship to complex neurovascular structures. The purpose of this study is to report our experience of the removal of CSCHs through a completely extradural transcavernous approach.

Methods: Twelve patients with CSCH, who were operated through a purely extradural approach, were retrospectively studied.

Metal-organic frameworks MIL-88A hexagonal microrods as a new photocatalyst for efficient decolorization of methylene blue dye.

Metal-organic frameworks (MOFs) MIL-88A hexagonal microrods as a new photocatalyst show an active performance for methylene blue (MB) dye decolorization using visible light. MB decolorization over the MIL-88A photocatalyst follows first-order kinetics. The addition of a H2O2 electron acceptor can markedly enhance the photocatalytic MB decoloration performance of MIL-88A.

Supracondylar transjugular tubercle approach to intradural lesions anterior or anterolateral to the craniocervical junction without resection of the occipital condyle.

Aim: To clarify the usefulness of supracondylar transjugular tubercle approach for treatment intradural lesions anterior and anterolateral to foramen magnum, in which the posterior portion of the jugular tubercle is removed extradurally through the condylar fossa with the atlanto-occipital joint intact.

Material And Methods: The supracondylar transjugular tubercle approach was applied to 28 craniocervical junction surgeries. These surgeries included clipping a vertebral artery aneurysm in 12 cases and removing intradural tumors ventral and ventrolateral to foramen magnum in 16 cases.

[Surgical management of petroclival meningiomas invading into cavernous sinus].

Objective: To analyze the clinical features, surgical strategy and management outcomes of petroclival meningioma invading into cavernous sinus.

Methods: Fifteen cases with petroclival meningioma invading into cavernous sinus were retrospectively analyzed. The presigmoidal approach was selected to remove tumors.
