Parent vessel occlusion via the balloon-assisted, dual microcatheter technique

Dual Microcatheter Retrograde Transvenous Obliteration of Gastric Varices: Coil Embolization as a Substitute for Balloon Occlusion

Dual microcatheter retrograde transvenous obliteration (DMRTO) of gastric varices enables dual microcatheters to be advanced to the gastric varices themselves or to a site adjacent to the varices. The sclerosing agent is infused through the first microcatheter following coil embolization of the outflow vessels through the second microcatheter, which is placed several centimeters back from the v...

Transarterial Balloon-assisted Onyx Embolization of Intracranial Arteriovenous Malformations Using a Dual-lumen Balloon Microcatheter: Two Case Reports

The Onyx system has been well established in recent years as a very important material in the treatment of arteriovenous malformations (AVMs). When using the Onyx, it is essential to wait for the creation of a plug around the tip of the catheter, which enables the effective forward penetration of Onyx. Recent reports have shown that the introduction of a dimethyl sulfoxide compatible dual-lumen...

Parent artery occlusion: a well-established technique.

Parent vessel occlusion for vertebrobasilar fusiform and dissecting aneurysms.

BACKGROUND AND PURPOSE Previous reports of outcome with permanent vessel occlusion (PVO) for large, giant, or fusiform aneurysms in the posterior circulation have been limited. We undertook this study to evaluate the perioperative (within 30 days) and follow-up outcomes for patients treated with permanent occlusion of the vertebral artery for vertebrobasilar fusiform and dissecting aneurysms. ...

Carotid ophthalmic aneurysm rupture after parent vessel occlusion.

We report causes leading to and rupture of a carotid ophthalmic aneurysm after treatment by parent vessel occlusion. The aneurysm was initially symptomatic but unruptured.
