Arteriovenous malformations of the brain are congenital vascular lesions that affect 0.01-0.50% of the population, and are generally present in patients aged 20-40 years. The usual clinical presentations are haemorrhage, seizures, progressive neurological deficit, or headache. Results of natural history studies have shown a yearly haemorrhage rate of 1-

Arteriovenous malformations (AVMs) are fast-flow vascular malformations composed of a complex vessel network directly connecting feeding arteries to draining veins. The intervening normal capillary network is absent. Proper diagnosis and treatment of AVMs is challenging and in need of an interdisciplinary team of experienced physicians.

Object. Important central nervous system (CNS) manifestations in patients with hereditary hemorrhagic telangiectasia (HHT) include arteriovenous malformations (AVMs) and dural arteriovenous fistulas (DAVFs). Hereditary hemorrhagic telangiectasia is caused by germline mutations of two genes: ENG (HHT Type 1) and ACVRL1 (HHT Type 2).

Arteriovenous malformations (AVMs) represent one of the most complex lesions encountered by the vascular neurosurgeon. They are thought to arise by a developmental aberration early in fetal life leading to structurally abnormal vessels, characterised by arteriovenous shunting. AVMs may present in a number of ways, the most devastating being hemorrhage.

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 ...

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 ...

BRAIN ARTERIOVENOUS MALFORMATIONS
Neuroimaging Clinics of North America, 1998The diagnostic evaluation of a brain arteriovenous malformation requires a thorough understanding of the imaging features seen on CT, MR, and conventional angiography. Therapeutic planning requires a comprehensive understanding of the angioarchitecture of AVMs, necessitation selective and superselective angiography in order to give an accurate ...

Uterine arteriovenous malformation
Archives of Gynecology and Obstetrics, 2004Uterine arteriovenous malformations are very rare and potentially life-threatening. They can present with menorrhagia, postpartum bleeding, postmenopausal bleeding, an asymptomatic mass, or congestive heart failure.We present a 37-year-old woman with massive uterine bleeding that started abruptly 3 weeks after D and C and was found to be due to ...

Uterine Arteriovenous Malformations
Seminars in Ultrasound, CT and MRI, 2021Uterine arteriovenous malformations are rare but may represent a life-threatening cause of vaginal bleeding. The typical patient affected is a multiparous woman during her thirties. The origin can be congenital or acquired, with the latter being more common after uterine surgery and presenting mainly as arteriovenous fistulous connections into the ...

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.
