First-Pass Recanalization with EmboTrap II in Acute Ischemic Stroke (FREE-AIS): A Multicenter Prospective Study.

Objective: We aimed to evaluate the efficacy of EmboTrap II in terms of first-pass recanalization and to determine whether it could yield favorable outcomes.

Materials And Methods: In this multicenter, prospective study, we consecutively enrolled patients who underwent mechanical thrombectomy using EmboTrap II as a front-line device. The primary outcome was the first pass effect (FPE) rate defined by modified Thrombolysis In Cerebral Infarction (mTICI) grade 2c or 3 by the first pass of EmboTrap II.

Clinical outcomes of rescue stenting for failed endovascular thrombectomy: a multicenter prospective registry.

Background: Mechanical thrombectomy (MT) is a primary endovascular modality for acute intracranial large vessel occlusion. However, further treatment, such as rescue stenting, is occasionally necessary for refractory cases. We aimed to investigate the efficacy and safety of rescue stenting in first-line MT failure and to identify the clinical factors affecting its clinical outcome.

Microsurgical efficacy and safety of a right-hemispheric approach for unruptured anterior communicating artery aneurysms.

Objective: We investigated the effectiveness of a right hemispheric surgical approach in treating unruptured anterior communicating artery aneurysms.

Methods: Between January 2005 and June 2012, 305 patients with anterior communicating artery (Acom) aneurysms were treated using the pterional approach. Among them, 113 who underwent microsurgery with an unruptured Acom aneurysm were enrolled in this study.

Relationship between Two Types of Coil Packing Densities Relative to Aneurysm Size.

Background And Purpose: Coil packing density (PD) can be calculated via a formula (PDF ) or software (PDS ). Two types of PD can be different from each other for same aneurysm. This study aimed to evaluate the interobserver agreement and relationships between the 2 types of PD relative to aneurysm size.

Coil embolization of overwide and undertall small intracranial aneurysms with double microcatheter technique.

Background: Overwide and undertall small intracranial aneurysms remain a challenge for coil embolization. The purpose of this study is to evaluate the feasibility and results of intrasaccular double microcatheter endovascular coil embolization of overwide and undertall small intracranial aneurysms.

Methods: Small (<7 mm), overwide (dome-to-neck ratio [DNR] ≤1.

Spinous process morphometry for interspinous device implantation in Korean patients.

Objective: To analyze the interspinous distance and the height, length, and thickness of the lumbar spinous process for interspinous device implantation in Korean patients.

Methods: Morphometric data obtained from plain radiographs of the lumbar and sacral spine were analyzed. The study included 60 matched subjects who visited an outpatient clinic for back pain.

Characteristics and management of residual or slowly recurred intracranial aneurysms.

Objective: Residual aneurysm from incomplete clipping or slowly recurrent aneurysm is associated with high risk of subarachnoid hemorrhage. We describe complete treatment of the lesions by surgical clipping or endovascular treatment.

Methods: We analyzed 11 patients of residual or recurrent aneurysms who had undergone surgical clipping from 1998 to 2009.
