Cerebral aneurysm sac growth as the etiology of recurrence after successful coil embolization.
BACKGROUND AND PURPOSE Coil compaction is thought to be the main mechanism for recurrence in cerebral aneurysms with previously successful coil embolization. We hypothesize that sac growth may be equally or more important. The objective was to study the relative roles of coil compaction and sac growth as explanations for aneurysm recurrence requiring retreatment in a study population using quan...
متن کاملAneurysm permeability following coil embolization: packing density and coil distribution
BACKGROUND Rates of durable aneurysm occlusion following coil embolization vary widely, and a better understanding of coil mass mechanics is desired. The goal of this study is to evaluate the impact of packing density and coil uniformity on aneurysm permeability. METHODS Aneurysm models were coiled using either Guglielmi detachable coils or Target coils. The permeability was assessed by takin...
متن کاملAneurysm regression after coil embolization of a concurrent aneurysm.
A 43-year-old woman with two incidental paraclinoid internal carotid artery aneurysms underwent coil embolization of the larger superior hypophyseal aneurysm and 10 weeks later underwent follow-up angiography that showed regression of the smaller, more distal paraclinoid aneurysm. We demonstrate that, although it is a rare occurrence, aneurysms can involute. We discuss potential mechanisms of t...
متن کاملSurgical Support System for Cerebral Aneurysm Coil Embolization
In the medical field, treatments with minimized size of surgery scars to reduce the physical demands of patients are widespread. A typical example of such treatments is a therapy using a catheter. This procedure involves inserting a thin tube called a catheter into a duct of the human body and treating an affected part from inside the duct. Recently, the catheter therapy is also used in the fie...
متن کاملEndovascular coil embolization of cerebral aneurysm remnants after incomplete surgical obliteration.
INTRODUCTION The presence of an aneurysm remnant after incomplete or unsuccessful surgical clipping is associated with persistent risk of regrowth and rupture, and additional treatment is generally recommended. Attempts at surgical re-exploration are technically difficult and carry significant risk. Endovascular therapy can represent a valuable therapeutic alterative in these cases. METHODS W...
