INTRODUCTION This study aimed to define the patterns of basal cerebral venous drainage (BCVD) from cavernous sinus dural arteriovenous fistulas (CSDAVFs). MATERIALS AND METHODS Forty sets of selective angiographic data from 36 patients with spontaneous CSDAVFs (age range, 53-79 years) were retrospectively analyzed for their drainage patterns. Three types(More)
BACKGROUND Radiation therapy is an effective approach in the treatment of highly radiosensitive brain tumors such as germinomas. However, recent studies have reported intellectual disturbances in patients who underwent whole-brain irradiation as children. We detected apoptosis in the infantile murine cerebrum after systemic X-ray irradiation. METHODS(More)
BACKGROUND The cavernous sinus communicates with several para-cavernous sinus venous structures, receiving blood flow from the superficial middle cerebral vein (SMCV), the sphenoparietal sinus (SPS), and the superior ophthalmic vein, and draining into the superior and inferior petrosal sinuses and pterygoid and basilar plexuses. Anatomic variations of these(More)
INTRODUCTION Vertebrobasilar artery occlusion (VBO) produces high mortality and morbidity due to low recanalization rate utilization in endovascular therapy. The use of percutaneous transluminal angioplasty (PTA) to improve recanalization rate additional to local intra-arterial fibrinolysis (LIF) was investigated in this study. Results obtained following(More)
PURPOSE The purpose of this study was to compare the characteristics of shaped microcatheters, including shapability, durability, and luminal changes. MATERIALS AND METHODS Eleven brands of steam-shaped microcatheters and one brand of preshaped microcatheter were evaluated. There were 2 nonreinforced and 10 reinforced devices supported by coils. For(More)
BACKGROUND AND PURPOSE Complete occlusion of intracranial aneurysms is the goal of endovascular treatment and is influenced by several aneurysm-related anatomic factors. The anatomic features of aneurysms can be characterized by three-dimensional reconstructed images by use of rotational digital subtraction angiography (3D-DSA). The purpose of this study(More)
OBJECT The authors compared the usefulness of three-dimensional (3D) reconstructed computerized tomography (CT) angiography with 3D digital subtraction (DS) angiography in assessing intracranial aneurysms after clip placement. A retrospective review of clinical cases was performed. METHODS Between May 2001 and May 2003, 17 patients with a total of 20(More)
SUMMARY The hypoglossal canal contains a venous plexus that connects the inferior petrous sinus, condylar vein, jugular vein and paravertebral plexus. The venous plexus is one of the venous drainage routes of the posterior skull base. Only a few cases of dural arteriovenous fistulas (AVFs) involving the hypoglossal canal have been reported. We describe(More)
A 36-year-old female patient was admitted to our hospital with a rare case of aneurysm at the origin of the accessory middle cerebral artery (MCA) manifesting as severe headache and vomiting. Neurological examination did not detect any abnormalities or consciousness disturbance. Computed tomography demonstrated diffuse subarachnoid hemorrhage. Magnetic(More)
INTRODUCTION The aims of this study were to evaluate the angioarchitecture of cavernous sinus dural arteriovenous fistulas (CSdAVFs), including the number and location of shunted pouches (SPs), and to evaluate whether the location and number of the SPs affect the outcomes of transvenous embolization of CSdAVFs. METHODS Nineteen consecutive cases of(More)
