Two Cases of Intracranial Aneurysm Treated with Coil Embolization Using the T-stenting Technique

抄録

Objective: We report two cases of unruptured intracranial aneurysms treated with the coil embolization using T-stenting technique.Case Presentations: Case 1 was a 49-year-old woman with wide-neck basilar tip aneurysm (10.8 mm × 9.8 mm × 8.9 mm) riding on the origin of the bilateral posterior cerebral arteries. Case 2 was an 84-year-old woman with left internal carotid artery-posterior communicating artery aneurysm (16.8 mm × 13.5 mm × 12.6 mm) and the ipsilateral posterior communicating artery (Pcom) was branched from the dome of the aneurysm. Both cases were treated with coil embolization using the T-stenting technique without any neurological deficits.Conclusion: Although the T-stenting technique is accompanied by a difficulty on the occasion of stent placement in comparison with the Y-stenting technique, such a technique has a potential benefit to reduce the risk of thrombotic complications.
