Development of sigmoid dural arteriovenous fistulas after transvenous embolization of cavernous dural arteriovenous fistulas.
A 54-year-old woman presented with left proptosis, chemosis, ophthalmoplegia, and tinnitus in March 1989. Angiography demonstrated a left cavernous DA VF. The feeding arteries from the left external carotid artery were embolized. Her symptoms were relieved for a while but soon recurred . On May 2, she was referred to us for treatment. Angiography revealed that all the branches of the left exter...
متن کاملTurn-back embolization technique for effective transvenous embolization of dural arteriovenous fistulas.
For effective transvenous embolization of DAVFs, it is important to place coils at the shunting venous pouch in the initial step of the procedure. When it was difficult to navigate a microcatheter to the shunting venous pouch due to the anatomic relationship of approach routes with targeted pouches, we navigated the microcatheters by a "turn-back technique" within the involved sinuses into the ...
متن کاملEndovascular Treatment of Intracranial Dural Arteriovenous Fistulas.
Endovascular treatment options for dural arteriovenous fistulas (DAVFs) have vastly expanded and become progressively safer in the last several years. Angiographic imaging systems have improved, catheter technology has advanced, and liquid embolic and coil options have increased. As a likely result, an increasing proportion of DAVFs are treated via an endovascular approach. In addition to allow...
متن کاملEndovascular management of intracranial dural arteriovenous fistulas.
Dural arteriovenous fistulas are a heterogeneous group of lesions that comprise 10-15% of intracranial vascular malformations. The treatment strategy is devised after careful consideration of the arterial supply, venous drainage, clinical presentation, and risk of progression, hemorrhage, or neurologic decline. With recent advancements in endovascular technology, the majority of dural arteriove...
متن کاملEndovascular management of spinal dural arteriovenous fistulas.
Spinal dural arteriovenous fistulas (dAVF) are the most common subset of the larger group of spinal vascular malformations. In this chapter, we discuss the definition, epidemiology, clinical presentation, diagnosis, treatment, and outcomes of spinal dAVF. Special attention is given to clinical approach, imaging, and diagnosis with discussion of newer spinal magnetic resonance angiographic techn...
