The cause of pulmonary arteriovenous fistulas after a cavopulmonary anastomosis is not clearly known, but the previous studies regarding their causes have been focused mainly on the hepatic factors. We report two unusual Fontan cases with multiple bilateral pulmonary arteriovenous fistulas. One of them died of progressive hypoxia, and the ...

Microscopic arteriovenous anastomoses are known structures that have many clinical implications, with disease states such as Reynaud's phenomenon and erythromelalgia known consequences of their abnormal functioning. These pre-capillary arteriovenous communications result in increased regional blood flow at the time of capillary filling. Recent advances in imaging technology, providing physiological and ...

The treatment of intracranial dural arteriovenous fistulas (AVF) has progressed considerably over the past few decades. With the introduction of new embolic materials and refinement of endovascular techniques, lesions that in the past may have required extensive surgery, or were considered untreatable, have increasingly become curable. Despite improvements in technology, ...

Vascular malformations occur as a result of an arrest in the development of the vascular system. The modified Hamburg classification distinguishes arterial, venous, arteriovenous, capillary, lymphatic, and mixed vascular malformations. Each malformation is further subdivided based on anatomy and on the time when arrest in development of the embryogenesis occurred; ...

Arteriovenous malformations (AVMs) are direct connections between arteries and veins associated with loss of the intervening capillary bed. In the lungs, pulmonary AVMs can result in right to left shunts and severe cyanosis and dyspnoea. However, the cellular and molecular mechanisms underlying AVM formation are poorly understood. One important clue ...

The temporal artery courses superficially over the temporal bone and thus can be vulnerable to trauma. Although traumatic lacerations of this vessel are indeed common, trauma-induced arteriovenous fistulae involving the temporal artery are relatively rare. Arteriovenous fistulae caused by iatrogenic injury to the temporal artery are rarer still. We report ...
