Coiling of aneurysms 3 mm in diameter or less has been associated with a relatively high rate of complications, including iatrogenic rupture. The present study aimed to determine the clinical outcome of our technique for coiling small aneurysms. ⋯ Aneurysms 3 mm in diameter or smaller can be coiled safely with the use of both bare platinum and hydrogel-coated coils. In most cases, coiling of small aneurysms can be performed without the use of adjunctive devices such as balloons or stents.

To report five patients who underwent cervical decompressive surgeries and developed persistent postoperative neurologic deficits compatible with spinal cord infarctions and evaluate causes for these rare complications. ⋯ Neuroimaging evaluation of spinal cord infarction after decompressive surgery is done to exclude spinal cord compression, to ensure adequate surgical decompression, and to confirm infarction by imaging. Antecedent, unrecognized preoperative vascular compromise may be a significant contributor to spinal cord infarction by itself or in combination with hypotension.

Clinical Trial
Posterior fossa reconstruction using titanium plate for the treatment of cerebellar ptosis after decompression for Chiari malformation.
We describe our use of a perforated titanium plate to perform a partial posterior fossa cranioplasty in the treatment of cerebellar ptosis and dural ectasia after posterior fossa decompression (PFD). ⋯ Placement of a titanium plate appears to be an effective method of treatment of cerebellar ptosis and dural ectasia after PFD for Chiari malformation.

This study was designed to evaluate the clinical, radiologic, histologic, and surgical outcome characteristics of this disease treated in a single institution. ⋯ Primary adult infradiaphragmatic craniopharyngiomas are relatively rare lesions occurring in young adults. Pituitary dysfunction, visual acuity and/or field deterioration, and headache were the most common chief symptoms. Transsphenoidal surgery, including tearing the cyst walls off the diaphragma sellae and protecting normal pituitary tissue as much as possible, is recommended. Although at the risk of impairing the function of anterior pituitary, transsphenoidal surgery results in a high rate of both visual field and hyperprolactinemia improvement with a low associated risk of recurrence. In terms of pathological aspects, the adamantinous subtype was more common.
