| Abstract |
|
Subarachnoid hemorrhage (SAH) from vertebral artery (VA) dissecting aneurysms is rare and potentially fatal. Early rebleeding from ruptured VA dissecting aneurysms excessively reduces favorable outcome rates of the ruptured dissecting aneurysms, so that early diagnosis and treatment are essential for preventing early rebleeding and devastating results. A 52-year-old man was referred to our hospital due to an abruptly developed severe headache and sequential mental change. SAH due to ruptured left VA dissecting aneurysm was noted. We performed early endovascular internal trapping, and successful flow arrest on final angiogram was confirmed. About 6 hours later after internal trapping of the aneurysm, his mentality abruptly deteriorated and rebleeding was confirmed. We present this case of early rebleeding from vertebral dissecting aneurysm after endovascular internal trapping, along with a literature review. |
