Large (or Bulbous) Basilar Bifurcation Aneurysms (12.5–25 mm) 265 Patients

  • Charles G. Drake
  • Sydney J. Peerless
  • Juha A. Hernesniemi


Two patients with remote bleeds 15 months and 4 years ago were classified with the 40 unruptured aneurysms (Table 4.1). In the remaining, besides the usual clinical symptoms of subarachnoid hemorrhage (SAH), 23 had CNIII palsy, one of them bilaterally. Trochlear nerve palsy was seen in four, one bilaterally, and sixth nerve palsy in seven patients, three times bilaterally.
