Filum terminale arteriovenous fistulae (FTAVF) are rare entities. For those with fistulous point located in the lower sacral region (below S2), neither surgical nor endovascular strategy are the optimal treatment.

Transvenous embolization (TE) has been increasingly applied for arteriovenous malformation (AVM) treatment. Transient cardiac standstill (TCS) has been described in cerebrovascular surgery but is unco...
An 80-year-old female presented with a long history of severe pulsatile tinnitus, vertigo, and decreased hearing. She was found to have a large right-sided tentorial arteriovenous fistula (AVF) with e...
Tanycytic ependymoma (TE), a rare subtype of ependymoma, was classified as grade II ependymoma by the World Health Organization in 2000 and 2007. Preoperative diagnosis of TE is challenging due to its...
The vascular access is the mainstay of hemodialysis. Arteriovenous fistula has been prioritized as the first choice of long-term vascular access for its inferior rate of complications and improved pat...
The purpose of this study is to determine whether surgical section of the filum terminale in children, when added to standard medical therapy, will result in a reliable and clinically-sign...
A new endovascular route for the treatment of brain AVMs may be possible in some cases: Trans-Venous Embolization (TVE). The technique uses microcatheters to navigate to the draining veins...
In previous studies exploring specific sequences of MRI (susceptibility weighted imaging (SWI) and arterial spin labeling (ASL)), the investigators have shown the great sensibility of thes...
The primary purpose of this study is to evaluate the safety and efficacy of partial splenic artery embolization in the treatment of symptomatic portal vein hypertension. A secondary aim is...
The primary purpose of this prospective, randomized trial is successful intravenous (IV) cannulation on first attempt with the use of either the Vein Viewer (VV) or standard cannulation me...
Fiberoptic endoscopy designed for duodenal observation and cannulation of VATER'S AMPULLA, in order to visualize the pancreatic and biliary duct system by retrograde injection of contrast media. Endoscopic (Vater) papillotomy (SPHINCTEROTOMY, ENDOSCOPIC) may be performed during this procedure.
Congenital arteriovenous malformation involving the VEIN OF GALEN, a large deep vein at the base of the brain. The rush of arterial blood directly into the vein of Galen, without passing through the CAPILLARIES, can overwhelm the heart and lead to CONGESTIVE HEART FAILURE.
A vessel that directly interconnects an artery and a vein, and that acts as a shunt to bypass the capillary bed. Not to be confused with surgical anastomosis, nor with arteriovenous fistula.
A method of hemostasis utilizing various agents such as Gelfoam, silastic, metal, glass, or plastic pellets, autologous clot, fat, and muscle as emboli. It has been used in the treatment of spinal cord and INTRACRANIAL ARTERIOVENOUS MALFORMATIONS, renal arteriovenous fistulas, gastrointestinal bleeding, epistaxis, hypersplenism, certain highly vascular tumors, traumatic rupture of blood vessels, and control of operative hemorrhage.
An abnormal direct communication between an artery and a vein without passing through the CAPILLARIES. An A-V fistula usually leads to the formation of a dilated sac-like connection, arteriovenous aneurysm. The locations and size of the shunts determine the degree of effects on the cardiovascular functions such as BLOOD PRESSURE and HEART RATE.
Surgery is a technology consisting of a physical intervention on tissues. All forms of surgery are considered invasive procedures; so-called "noninvasive surgery" usually refers to an excision that does not penetrate the structure being exci...
