Cerebral AVM's consist of an abnormally large connection between the arterial and the venous systems resulting in a wide variety of configurations, which are grossly subdivided into five types. Emphasis is given to the basic surgical principles of first understanding the nature of the lesion; second, having a thorough preoperative awareness of the ...

Pulmonary Arteriovenous Malformations
Chest, 2013Pulmonary arteriovenous malformations (PAVMs) are abnormal vascular structures that most often connect a pulmonary artery to a pulmonary vein, bypassing the normal pulmonary capillary bed and resulting in an intrapulmonary right-to-left shunt. As a consequence, patients with PAVM can have hypoxemia and paradoxical embolization complications, including ...

Brain arteriovenous malformations
Nature Reviews Disease Primers, 2015An arteriovenous malformation is a tangle of dysplastic vessels (nidus) fed by arteries and drained by veins without intervening capillaries, forming a high-flow, low-resistance shunt between the arterial and venous systems. Arteriovenous malformations in the brain have a low estimated prevalence but are an important cause of intracerebral haemorrhage ...

Pancreatic Arteriovenous Malformation
Digestive Surgery, 2003We report a case of a 57-year-old male with a pancreatic arteriovenous malformation (AVM). The diagnosis was made by CT scan and angiography. In the reported case, bleeding from AVM into the biliary tract caused haemobilia and bleeding into the pancreatic head caused abdominal pain. Pancreatic AVM has been only rarely reported as a cause of haemobilia.

Bruits and Arteriovenous Malformations
Archives of Neurology, 1977To the Editor.— Bruits were noted in 12 of 25 patients with angiographically demonstrated arteriovenous malformations (AVMs) encountered in a 15-year period. There was a significant correlation of bruits to both size (larger than 3 × 3 cm in 12 of 14) and duration of symptoms (longer than five years in 11 of 13) in the 23 patients with exclusively ...

Intrarenal Arteriovenous Malformation
Journal of Urology, 1980Our surgical experience with 7 cases of intrarenal vascular malformation is reported. Based on angiographic criteria the so-called congenital arteriovenous fistula of the kidney may be classified either as the cirsoid type, which represents a truly congenital form of arteriovenous malformation, or as the aneurysmal type, which is considered to be ...

Arteriovenous malformations in the brain
Current Treatment Options in Neurology, 2002Arteriovenous malformations (AVM) are a leading cause of intracerebral hemorrhage, especially among the young. Because they pose a lifelong risk of serious bleeding, definitive treatment to obliterate the AVM should be pursued in the majority of patients.

Arteriovenous malformations of the colon
The American Journal of Surgery, 1977Arteriovenous malformations have become recognized as a major cause of massive bleeding of the colonic origin. Although an arteriographic unit capable of serial magnification is ideal for detecting arteriovenous malformations in the bowel, the diagnosis may still be made by a combined approach of conventional arteriography, colonoscopy and operative ...
