Percutaneous Coil Embolization for the Treatment of a Giant Brachial Artery Pseudoaneurym in a Child.

Brachial artery pseudoaneurysm is a rare phenomenon. When a diagnosis of brachial artery pseudoaneurysm is established, early and appropriate treatment should be performed as soon as possible to prevent possible complications, such as hemorrhage, rupture, and upper limb and finger losses. Open surgical repair is usually the cornerstone of treatment; however, we here report a case of giant brachial pseudoaneurysm in a 2-year-old girl, which was successfully treated with percutaneous coil embolization.

Spontaneous occlusion of cerebral arteriovenous malformation following partial embolization with Onyx.

Management options for brain arteriovenous malformations (AVMs) are surgery, radiosurgery, and endovascular embolization. The aim of partial embolization in endovascular treatment is to make total resection possible. However, increased risk of bleeding in partial embolization creates some controversies about treatment options.
