Dural 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, and vein of Galen malformations. For each lesion type, epidemiology, clinical presentation, imaging findings, classification considerations, and treatment options are discussed.

Background And Objectives: There is no dedicated occlusive device for closing coronary artery fistulas (CAFs), and specific efficacy and safety data of various off-label occlusive devices for CAFs closure are scarce.
Methods: Patients undergoing transcatheter closure of CAFs from January 2011 to December 2022 were included in the single-center retrospective study. The study population was divided into 2 groups: coils group (n=35) and patent ductus arteriosus (PDA) occluders group (n=66).

BACKGROUND Arterioportal fistulas (APFs) are abnormal connections between the arterial and portal venous systems, leading to portal hypertension (PH) and symptoms such as gastrointestinal bleeding, splenomegaly, and hepatic pain. Symptoms typically appear by the age of 2 years in about 75% of cases. CASE REPORT A 7-year-old boy with an asymptomatic APF developed life-threatening complications following a Clostridium difficile infection.

Arteriovenous malformation (AVM, arteriovenous dysplasia) is one of the variants of congenital vascular defects formed as a result of a defect in the development of the arterial and venous systems during ontogenesis with the formation of direct messages between vessels of different diameters. In this regard, high-speed shunting of blood from the arterial part of the vascular system to the venous through fistulas of various calibers occurs. This disease is characterized by a variety of clinical manifestations.

A superior mesenteric arteriovenous fistula (SMAVF) following gastrointestinal surgery represents a rare vascular complication. Enhanced computed tomography with 3-dimensional reconstruction proves to be the most efficacious modality for detecting this uncommon entity. Superior mesenteric angiography becomes imperative to accurately delineate the location and extent of mesenteric vessel involvement, which is essential for devising an optimal treatment strategy.
