Dural arteriovenous fistulas (dAVF) are abnormal arteriovenous shunts between meningeal arteries and intracranial dural sinuses or veins. This chapter discusses the anatomy, classification schemes, pathophysiology, clinical presentation, pediatric dAVFs, imaging characteristics, natural history, and management.

Portosystemic arteriovenous fistulas
Gastrointestinal Radiology, 1980The authors report the angiographic demonstration of arteriovenous fistulas in three patients. The fistula was believed to be spontaneous in one case, related to abdominal surgery and to abdominal trauma in the other two cases. The importance of angiography in the diagnosis and evaluation of this disease has been emphasized in the literature.

The Journal of Trauma: Injury, Infection, and Critical Care, 1987
We present a case of a splenic arteriovenous fistula (AVF) occurring postsplenectomy. The splenectomy was performed as a result of severe blunt abdominal trauma. The fistula was discovered in the postoperative period and controlled with intravascular coils. Splenic AVF are usually due to rupture of a pre-existing splenic artery aneurysm, post-traumatic,

The physiology of an arteriovenous fistula
The American Journal of Surgery, 1923Cardiac hypertrophy and proximal dilatation of the artery have been so frequently associated with arteriovenous fistulas that it has long seemed highly probable that there must be some causative relationship between the two. That such a relation exists has been denied by clinicians, both ancient and modern, and the association of the two conditions ...

Cerebral arteriovenous fistulae
2021Dural arteriovenous fistulae (dAVFs) are diverse, complex lesions that share the common feature of arteriovenous shunting without an intervening nidus. In this chapter, the ensuing discussion is organized by dAVF location, followed by further consideration of less common, distinct types of dAVFs-carotid cavernous fistulae, pial arteriovenous fistulae ...
