Modern endovascular methods of treatment of arteriovenous anastomoses:

• Using spirals or balloons
• With the help of liquid embolizing substances

Arteriovenous fistula is an abnormal connection between the artery and the vein. Native pathology is often combined with the presence of several communication vessels. In this regard, the complete elimination of pathology is often impossible. Treatment can consist in embolizing the area of pathology by the method of stationary occlusion or in its surgical removal.

Examples of treatment of arteriovenous anastomoses

AV shunt of anterior cerebral artery

The operation was performed by the method of stationary balloon occlusion of the place of formation of pathological shunting

Before surgery

After surgery

Angiogram of AVM mixed type of spinal cord

Before exclusion from the circulation

After the operation, the AVM is turned off from the circulation

Arteriovenous anastomoses mixed type

CT scan before surgery

The AV shunt of the posterior cerebral artery is disconnected using separable GDC spirals

Before surgery

After surgery

Before surgery

After surgery

From the pool of the internal carotid artery AVM is disconnected from the blood stream using a liquid embolizing agent

Before embolization

Thrombotic fluid in the AVM structure

After embolization
