Coil embolization of very small (2 mm or smaller) berry aneurysms: feasibility and technical issues.
BACKGROUND AND PURPOSE The very small size of cerebral aneurysms is considered to be one of the limitations for endovascular treatment, with a high risk for intraoperative rupture. We report on treatment of very small saccular ruptured cerebral aneurysms by coil embolization. All the cases were of 2-mm aneurysms with at least 1 of the dimensions being less than 2 mm. MATERIALS AND METHODS We ...
متن کاملResults of Endovascular Coil Embolization Treatment for Small (≤ 5 mm) Unruptured Intracranial Aneurysms
OBJECTIVE Researchers and clinicians have been unable to fully elucidate the natural course of and proper treatment for unruptured intracranial aneurysms (UIAs) smaller than or equal to 5 mm, particularly with regard to whether close observation or surgery is more appropriate. In this retrospective study, we evaluated the safety and efficacy of endovascular coil embolization of small (≤ 5 mm) a...
متن کاملClinical and angiographic results of coiling of 196 very small (< or = 3 mm) intracranial aneurysms.
BACKGROUND AND PURPOSE Coiling of very small (< or = 3 mm) aneurysms is considered controversial because of technical difficulties and a higher rate of procedural aneurysm ruptures. In this study, we report clinical and angiographic results of coiling of aneurysms 3 mm or smaller in comparison with larger aneurysms in a large, single-center cohort of patients. MATERIALS AND METHODS Between 19...
متن کاملExpanding Endovascular Therapy of Very Small Ruptured Aneurysms with the 1.5-mm Coil.
BACKGROUND Very small ruptured aneurysms (≤3 mm) demonstrate a significant risk for procedural rupture with endovascular therapy. Since 2007, 1.5-mm-diameter coils have been available (Micrus, Microvention, and ev3), allowing neurointerventionalists the opportunity to offer patients with very small aneurysms endovascular treatment. In this study, we review the clinical and angiographic outcome ...
متن کاملDouble microcatheter technique for detachable coil treatment of large, wide-necked intracranial aneurysms.
We describe a technique used to treat two patients with large, wide-necked aneurysms during the past 2 years. In the initial attempts at embolization, evidence of coil instability within the aneurysm or significant impingement of coil loops on the parent artery was observed. Advancement of a second microcatheter into the aneurysm allowed two coils to be braced across the aneurysmal neck before ...
