Verification of bleeding points in carotid blowout syndrome using guidewire manipulation.

Purpose: Carotid blowout syndrome (CBS) is a catastrophic complication of aggressive treatment of head and neck cancer. Early detection of bleeding points with embolization is a life-saving procedure; however, some bleeding points may be difficult to identify. Our aim was to determine whether guidewire manipulation (GWM) could be used to verify bleeding point locations in patients with CBS.

Transvenous Coil Embolization of Cavernous Sinus Dural Arteriovenous Fistula on a Revised Classification.

Background: Transvenous coil embolization is an effective method to manage cavernous sinus dural arteriovenous fistulas (CSDAVFs). However, some CSDAVFs may be associated with complex angioarchitecture, leading to difficult access. In this article we report our experience with coil embolization of CSDAVFs.

Aggressive cavernous sinus dural arteriovenous fistula: Angioarchitecture analysis and embolization by various approaches.

Background: Most cavernous sinus dural arteriovenous fistulas (CSDAVFs) present with benign neuro-ophthalmic symptoms. CSDAVFs manifesting with aggressive neurologic symptoms are rare. The purpose of this study was to analyze the different angioarchitectures of aggressive CSDAVFs and to report our experiences of embolization.

Transvenous embolization of cavernous sinus dural arteriovenous fistula via angiographic occlusive inferior petrous sinus.

Background: Trans-inferior petrous sinus (IPS) coil embolization is an efficient and safe method to manage cavernous sinus dural arteriovenous fistulas (CSDAVFs). However, some CSDAVFs may be associated with angiographic occlusive IPS making access difficult. The purpose of this study was to report our experience of transvenous embolization of the CSDAVF via angiographic occlusive IPS.

Anatomic Variation of Facial Vein in Carotid-Cavernous Fistula and Trans-Facial Vein Embolization.

Objective: Trans-facial vein (FV) embolization via the internal jugular vein is an alternative approach to embolization of carotid cavernous fistulas (CCFs). The purpose of this study is to report the anatomic variation of FVs and our experience of trans-FV embolization of CCFs.

Methods: Over 6 years, 26 patients (12 men and 14 women; age range 27-72 years old) with CCFs underwent trans-FV embolization because of anterior drainage of fistulas.
