WEB Clinical Assessment of IntraSaccular Aneurysm Therapy (WEBCAST)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01778322
Recruitment Status : Completed
First Posted : January 29, 2013
Last Update Posted : March 15, 2023

Microvention-Terumo, Inc.

Brief Summary:
The objective of this clinical study is to evaluate clinical utility of the WEB Aneurysm Embolization System used to embolize intracranial aneurysms

Condition or disease Intervention/treatment
Intracranial Aneurysm Procedure: Intracranial aneurysm embolization

Detailed Description:

The following parameters will be evaluated as part of this study:

  • Aneurysm morphology
  • Aneurysm size
  • For ruptured aneurysms: Hunt and Hess Classification of Subarachnoid Hemorrhage (SAH)
  • Size of the embolization device(s) used in the procedure
  • Intra-procedural assessment of aneurysm occlusion and flow stasis
  • Degree of aneurysm occlusion post-procedure (percentage occlusion, Raymond Scale and other scores as appropriate)
  • Aneurysm occlusion durability
  • Recanalization rate
  • Device-related changes in Modified Rankin Scale from baseline
  • Complications/adverse events
  • Rebleed/new bleed

Index Embolization Cohort
WEB Aneurysm Embolization System
Procedure: Intracranial aneurysm embolization
Treatment of intracranial aneurysms

Primary Outcome Measures :
  1. Durability of occlusion [ Time Frame: 6 months ]
    Evaluated by the Corelab

Secondary Outcome Measures :
  1. Recurrence/recanalization rate [ Time Frame: 6 months ]
    Evaluated by the Corelab, based on Raymond Roy occlusion scale

  2. Modified Raymond Scale [ Time Frame: 6 months ]
    Evaluation of patient's functional level of activity by the physician

  3. Percentage occlusion of target aneurysm [ Time Frame: 6 months ]
    Evaluated by the Corelab

Other Outcome Measures:
  1. Fluoroscopy time [ Time Frame: procedure ]
    Duration of fluoroscopy time will be recorded during the procedure
