Within the past decade, endovascular coiling has proven to be safe and effective and has supplanted neurosurgical clipping as a first line treatment. However, coiling of very small aneurysms ( <4 mm) has been considered controversial because of conflicting data about their rate of rupture and the technical difficulties associated with repair. Improvements in technology and new techniques have renewed interest in the endovascular treatment of these aneurysms. This exhibit will review feasibility of endovascular occlusion, which factors predict successful occlusion, indication for the procedure and the various techniques and their risks.

Introduction Natural history: Rupture and Re-rupture rates. Is it feasible?: Size, Location, Anatomy, Un-ruptured vs ruptured Is it safe?: Complications, Rate of hemorrhage, Patient status, Un-ruptured vs ruptured Techniques: Standard single microcatheter approach, Multiple microcatheters, Balloon assisted, Stent assisted. Indications and Contraindications. Follow-up

Occlusion of very small aneurysms have similar long term results as larger aneurysms.  Techniques available for the Interventional Neuroradiologist to successfully occlude very small aneurysms.  Indications for endovascular occlusion
