Background: Intracranial dural arteriovenous fistulas (DAVF) are relatively rare vascular malformations. While the pathophysiology of their formation is unknown, they believed to be acquired lesions related intracranial venous hypertension and dura sinus thrombosis. There have been reports tumors associated with DAVF. Here we complete a systematic search literature. Methods: A PRISMA literature...

BACKGROUND The knowledge of the location and morphometric of the lateral venous sinus (transverse and sigmoid), and their relationship with the asterion and other surface anatomical landmarks, it is imperative for posterolateral approaches to the posterior cranial fossa to avoid vascular structures injury and surgical complications. OBJECTIVE Determine an anatomical area security for a drill ...

A 28-year-old woman had a normal delivery (primipara) on January 15, 2009. On March 20, 2009, she suffered sudden onset of severe headache. Protein-S and protein-C levels were within the normal ranges. Computed tomography on admission showed no subarachnoid hemorrhage, and the patient was discharge with analgesic treatment. Four days later the patient presented again to our emergency department...

Purpose: Compromising the endolymphatic sac in the skull base approaches impose a high risk of progressive hearing loss. The authors topographically measured the relationship between endolymphatic sac (ES) and the surrounding anatomic structures in an effort finding the safety distance while incising the presigmoidal dura. Material and methods: Three imported formalin-fixed latex-injected cadav...

BACKGROUND AND PURPOSE To study hemodynamic changes and to determine the value of contrast-enhanced transcranial color-coded sonography (TCCS) for the evaluation of dural arteriovenous fistulae (DAVF) before and after transcatheter embolization. METHODS Twenty-four patients (mean age 61+/-11 years) with occipitally located DAVF were studied with contrast-enhanced TCCS using the transtemporal ...

OBJECTIVE To evaluate the role of transvenous embolization in the treatment of intracranial dural arteriovenous fistulas (DAVFs), including its efficacy and safety. METHODS We retrospectively studied the charts of 24 patients (21 women and 3 men) treated for an intracranial DAVF since 1990 in whom a transvenous approach was attempted either alone (16 patients) or in combination with arterial ...
