PURPOSE: Tiny @entity438 pose a significant therapeutic challenge for interventional neuroradiologists. The authors report their preliminary results of endovascular treatment of these @entity439 . METHODS: Between January 2002 and December 2009, 52 tiny @entity438 (defined as  <= 3 mm in maximum diameter) in 46 @entity1 (22 @entity1 ; mean age, 57.9 years) were treated by endosaccular coil embolisation or sole stent deployment in the parent artery. Of 52 @entity439 , 29 had @entity397 and 23 remained unruptured. The initial angiographic results, procedural complications, and clinical outcomes were assessed at discharge. Imaging follow-up was performed with cerebral angiography. RESULTS: One @entity439 coiling procedure failed because of unsuccessful micro-catheterization. Forty-three @entity439 were successfully coil embolized, of which complete occlusion was obtained in 14, @entity432 in 11. The other 8 @entity439 were treated by sole stent deployment in the parent artery. Procedural complications (2 intraprocedural ruptures and 3 @entity1031 events) occurred in 5 (9.6%) of 52 @entity439 , resulting in permanent morbidity in only 1 (2.2%, 1/46) @entity1 . No rebleeding occurred during clinical follow-up (mean duration, 46.7 months). Of the 16 @entity439 that receiving repetitive angiography, 6 initially completely and 3 subtotally @entity439 remained unchanged, 4 initially subtotally and 3 @entity439 progressed to total occlusion. Five sole stent deployed @entity439 received angiographic follow-up (mean duration, 10.0 months), of which 3 remained unchanged, 1 became smaller and 1 progressed to total occlusion. CONCLUSION: Endovascular treatment of tiny @entity438 is technical feasible and relatively safe. Coil embolisation seems to be effective in preventing early recanalisation, whereas sole stenting technique needs further investigation to determine its effectiveness.
