Arteriovenous malformations have a significant cumulative risk for hemorrhage. Treatment options include observation, microsurgical resection, stereotactic radiosurgery, embolization, and multimodal treatment. Treatment selection and timing are based upon AVM features including size, location in eloquent versus non-eloquent parenchyma, pattern of venous drainage, surgical access, rupture status, and prior treatments. Spetzler-Martin grading is the most commonly used classification system used to select treatment, with grades I and II lesions amenable to surgical resection alone, grade III lesions typically treated via a multimodal approach entailing pre-operative embolization followed by microsurgical resection, and grades IV and V lesions generally observed unless ruptured. Embolization in the treatment of AVMs is thus most commonly used as a pre-operative or, occasionally, pre-radiosurgical adjunct. The concept of curative AVM embolization is an attractive one which has emerged within the past few decades, with increasing clinical evidence for its safety and efficacy in recent years. Obliteration rates for curative AVM embolization will be improved by innovation in endovascular techniques and technologies.

Insufficient nidus occlusion is a matter of great concern to routine Onyx embolization of brain arteriovenous malformations (AVMs). This paper described an efficient method which using the diluted Ony...
Arteriovenous malformations frequently require multimodal therapy. Lesions are frequently preoperatively embolized preceding microsurgical resection. The use of intraoperative angiography in a hybrid ...
Embolization of arteriovenous malformations is characteristically used as part of a multimodal treatment approach, pre-operatively to facilitate microsurgical resection or as a preradiosurgical adjunc...
The NASSAU (New ASSessment of cerebral Arteriovenous Malformations yet Unruptured) Analysis: Are the Results From The ARUBA Trial Also Applicable to Unruptured Arteriovenous Malformations Deemed Suitable for Gamma Knife Surgery?
The optimal management of unruptured brain arteriovenous malformations (AVMs) is controversial after the ARUBA trial.
Intracranial arteriovenous malformations (AVMs) consist of an abnormal nidus of blood vessels that shunt blood directly from an artery to a vein and thereby bypass an intervening capillary bed. AVMs m...
In previous studies exploring specific sequences of MRI (susceptibility weighted imaging (SWI) and arterial spin labeling (ASL)), the investigators have shown the great sensibility of thes...
The cerebral arteriovenous malformations correspond to the formation of an entanglement of morphologically abnormal vessels called nidus, which shunt the blood circulation directly from th...
The time-frame and the follow-up elements after embolization of brain arteriovenous malformations are not standardized. Therefore, few reliable follow-up data are available for these patie...
The study is a prospective, multicenter, multinational study to assess the safety and performance of the Easyx (trade name) Antia Liquid Embolic during embolization of intracranial malform...
To evaluate the clinical benefits and risks of hybrid operating techniques in management of cerebral arteriovenous malformations.
A method of hemostasis utilizing various agents such as Gelfoam, silastic, metal, glass, or plastic pellets, autologous clot, fat, and muscle as emboli. It has been used in the treatment of spinal cord and INTRACRANIAL ARTERIOVENOUS MALFORMATIONS, renal arteriovenous fistulas, gastrointestinal bleeding, epistaxis, hypersplenism, certain highly vascular tumors, traumatic rupture of blood vessels, and control of operative hemorrhage.
Abnormal formation of blood vessels that shunt arterial blood directly into veins without passing through the CAPILLARIES. They usually are crooked, dilated, and with thick vessel walls. A common type is the congenital arteriovenous fistula. The lack of blood flow and oxygen in the capillaries can lead to tissue damage in the affected areas.
A congenital disorder that is characterized by a triad of capillary malformations (HEMANGIOMA), venous malformations (ARTERIOVENOUS FISTULA), and soft tissue or bony hypertrophy of the limb. This syndrome is caused by mutations in the VG5Q gene which encodes a strong angiogenesis stimulator.
A spectrum of congenital, inherited, or acquired abnormalities in BLOOD VESSELS that can adversely affect the normal blood flow in ARTERIES or VEINS. Most are congenital defects such as abnormal communications between blood vessels (fistula), shunting of arterial blood directly into veins bypassing the CAPILLARIES (arteriovenous malformations), formation of large dilated blood blood-filled vessels (cavernous angioma), and swollen capillaries (capillary telangiectases). In rare cases, vascular malformations can result from trauma or diseases.
Bleeding within the subcortical regions of cerebral hemispheres (BASAL GANGLIA). It is often associated with HYPERTENSION or ARTERIOVENOUS MALFORMATIONS. Clinical manifestations may include HEADACHE; DYSKINESIAS; and HEMIPARESIS.
Surgery is a technology consisting of a physical intervention on tissues. All forms of surgery are considered invasive procedures; so-called "noninvasive surgery" usually refers to an excision that does not penetrate the structure being exci...
