The algorithm of treatment of septic lateral sinus thrombosis (SLST) has undergone a paradigm shift with the understanding of the natural history of sigmoid sinus thrombosis. Thus, the recent medical literature promulgates the management of these cases with no sinus exploration. However, in view of marked paucity of literature on the cited subject, not much is known about this form of treatment...

BACKGROUND Aneurysmal rupture accounts for the majority of nontraumatic subarachnoid hemorrhage (SAH). Increasingly recognized is the occurrence of nontraumatic convexity SAH unaccounted for by aneurysmal rupture. CASE REPORT These presentations require consideration of rare but clinically significant sources of SAH. We report a patient presenting with prolonged mild headaches and acute onset...

We present a rare case of Venous Thrombosis in Subclavian, Axillary, Brachial Veins with extension to Internal Jugular vein, right sigmoid sinus and simultaneous Pulmonary embolism during the treatment with low molecular weight heparin.

Purpose Transcatheter angiography is the gold standard for evaluating the condition and anatomy of the dural sinuses in patients with arteriovenous fistulas (AVFs); however, the patency and intraluminal condition of the dural sinuses can also be evaluated on magnetic resonance imaging (MRI). The purpose of this study was to evaluate the usefulness of MRI for the diagnosis of sinus occlusion. Ma...

BACKGROUND AND PURPOSE Combined transarterial balloon-assisted endovascular embolization with double-lumen balloon microcatheters and concomitant transvenous balloon protection was described as a promising treatment technique for dural arteriovenous fistulae of the transverse and sigmoid sinus. The purpose of this study was to evaluate the technical efficacy and safety of this combined treatmen...

BACKGROUND AND PURPOSE Blood flow of the internal jugular vein and intracranial venous sinuses is affected by respiratory state. The purpose of this study was to clarify the changes in flow velocity and direction and signal intensities of sigmoid sinuses on phase-contrast (PC) MR images obtained with regular breathing and with deep inspiratory breath holding. METHODS One hundred seven subject...

Two cases of a second dural arteriovenous fistula (DAVF), both developing in different locations after selective transvenous embolization of the first DAVF, are presented. One recurrent DAVF developed on the sigmoid sinus 5 months after transvenous embolization of a DAVF in the paratransverse sinus channel, and the other recurrence developed around the jugular bulb 5 months after transvenous em...

A 62-year-old woman was evaluated for tinnitis and headache. Magnetic resonance imaging and angiography revealed the coexistence of a tentorial tumor encroaching the junction of the right transverse-sigmoid sinuses, and dural arteriovenous fistulous malformation (AVFM) of the right transverse sinus. AVFM was not manipulated at all during the surgery. The pathology was fibroblastic meningioma. P...
