Long-term clinical and radiologic results of small cerebral aneurysms embolized with 1 or 2 detachable coils

Stent-assisted coiling of very small wide-necked intracranial aneurysms: Complications, anatomical results and clinical outcomes

“…In our series, stent was successfully deployed in 104 of 108 patients (96.3%), stent deployment failed in 3.7% of patients. The results of two other studies were similar to ours [13][14][15]. Procedural rupture, one of the most significant complications of coiling, may be caused by perforation with the microguidewire or microcatheter, or may occur during coil placement.…”

“…Several earlier reports stated that the risk of intraprocedural aneurysm rupture is higher if the aneurysm is <3 mm in maximum diameter. Jun L et al reported an intraprocedural rupture rate of 3.8% [14]. Van Rooij et al and Nguyen et al reported that the intraprocedural rupture rate of very small aneurysms was more than twice (7.7%) and five times (11.7%) that of the rate of larger aneurysms, respectively [17,18].…”

Endovascular embolization of small ruptured intracranial aneurysms using a biplane angiographic system with three-dimensional rotational digital subtraction angiography

“…11,12 A high coil packing ratio is harder to accomplish in small aneurysms than in larger ones because of the risk of rupture during embolization and the tendency for coils to drop out of the microcatheter during endovascular packing. 4 We used 3D GDCs to form the initial basket framing, with coil loops bridging the aneurysm neck. This avoids protrusion into the parent artery and allows for complete treatment of some wide-necked aneurysms.…”

“…Endovascular surgery for these lesions is challenging because of technical difficulties, aneurysm rupture and coil migration. 4 We aimed to retrospectively review our experience of endovascular embolization of small ruptured intracranial aneurysms with particular regard to efficacy and safety.…”

Sole Stenting Technique for the Treatment of Uncoilable Very Small Aneurysms in the Intracranial Internal Carotid Artery

“…However, coil embolization of very small aneurysms has been considered controversial because of technical difficulties, such as initial selection or reselection after dropping out of microcatheters during coil packing and high rate of procedural aneurysm rupture. 19) In these cases, surgical clipping is also prone to technical difficulty because very small aneurysms are often thin-walled and may be too small to accept a clip without narrowing or tearing of the parent vessel. 23) Although several recent studies including meta-analysis have shown the feasibility and good results of coil embolization for very small aneurysms, the reported procedural rupture rate was higher than that of larger aneurysm (À3 mm diameter).…”
