We report 2 cases of symptomatic delayed vasospasm after neck clipping of unruptured juxta-dural ring aneurysms of the left internal carotid artery. Case 1 is a 53-year-old woman with multiple unruptured juxta-dural ring aneurysms. Case 2 is a 21-year-old woman with a carotid ophthalmic aneurysm. Aphasia and/or Gerstmann syndrome appeared 8 days and 12 days after clipping surgery, respectively. Angiograms revealed severe vasospasm of the left middle cerebral artery in Case 1 and the left M2 portion in Case 2. These symptoms were fully resolved by intra-arterial papaverine treatment and hyperbaric oxygen therapy. We emphasize that vasospasm is a possible complication after clipping of unruptured juxta-dural ring aneurysms.
