The SolitaireTM AB Neurovascular Remodeling Device (ev3, Irvine, CA, USA) is used to retain coils within an aneurysm, reducing the risk of embolic complications from coil herniation into the parent artery. Stents are deployed after confirming the optimal position of the stent markers across the aneurysm to avoid entry into perforators or branching arteries. Stent marker position is very important to prevent perforating or branching artery infarction. We performed stent-assisted coil embolization using the Solitaire AB stent to treat 2 aneurysms simultaneously. After successful coil embolization, we detached the Solitaire stent in the usual manner. However, the proximal stent marker, which was located at the horizontal segment of the cavernous internal carotid artery, moved into the meningohypophyseal trunk and occluded it. Although the distal markers were positioned optimally, we did not expect the proximal marker to be in the position where it was located. Fortunately, cranial nerve dysfunctions and pituitary deficiency did not develop. It is important to prevent ischemic injury by occlusion of the perforators or branching vessels that can be caused by malpositioned stent markers. We consider where the proximal marker of the stent might be located after detachment.

✓ Two cases of sphenoethmoidal encephalocele with cleft palate are reported in detail. The encephaloceles had prolapsed into the nose and nasopharynx, and protruded into the mouth. Previous examples of this entity are reviewed. Such patients have a typical facial appearance: hypertelorism, median cleft lip, and bifid nose of varied severity. Ocular findings include coloboma of the optic nerve or anophthalmia. The prolapsed cerebral tissue varies from nonfunctional glia elements to vital structures of the hypothalamus-pituitary area. Agenesis of the corpus callosum has been reported consistently. Transcranial access to the bone defect, particularly its posterior portion, is difficult because of distorted cerebral anatomy and abnormal vasculature. The fragility of the prolapsed cerebral tissue makes it difficult to preserve the cerebral tissue intact and to reposition it into the cranium. When there is a cleft palate, it is possible to repair the encephalocele extracranially through a transoral, transpalatal approach, preserving and repositioning the content of the sac. Dural closure and obliteration of the bone defects are other essential steps of the operation. Both patients reported here were successfully operated on by the transoral, transpalatal route, at the age of 3 months and 4 years, respectively. They were followed for several years and had comprehensive endocrinological work-ups. One patient exhibited some pituitary deficiency requiring substitution therapy.
