Y-configured Stent with a Double Microcatheter Technique for Ruptured Complex Basilar Tip Aneurysm. A Case Report

A 79-year-old woman had a sudden onset severe headache and became somnolent. On the first day in the hospital, diagnostic cerebral angiography revealed a small broad-necked basilar tip aneurysm with a bleb near the neck. Due to the unfavorable configuration of aneurysm, we decided to use a Y-configured stent with a double microcatheter technique. Although procedural rupture on the bleb near the neck occurred, perioperative neurological state was not changed and her clinical course was uneventful. Because of the stent, complete packing of the aneurysm was possible, hemodynamic stress at the inflow area was reduced and consequently the chance of rebleeding may decrease. Stenting with a double microcatheter technique can be an effective treatment for highly complex intracranial aneurysms.
