Case ReportsTraumatic anterior communicating artery pseudoaneurysm with cavernous sinus fistula.
A traumatic carotid-cavernous fistula and an intracranial pseudoaneurysm are uncommon but well-known complications of head trauma. A rare subtype of arteriovenous fistula may occur from a pseudoaneurysm of the anterior communicating artery (AcoA) instead of the internal carotid artery. We describe a patient with a traumatic pseudoaneurysm of the AcoA with a cavernous sinus fistula treated with endovascular treatment. ⋯ The AcoA, left anterior cerebral artery and part of the pseudoaneurysm were obliterated by coil embolization. A postoperative angiogram showed no flow through the pseudoaneurysm and the cavernous sinus fistula. A traumatic AcoA pseudoaneurysm with a cavernous sinus fistula may occur as an extremely rare complication of head injury.

Minimally invasive dorsal percutaneous spondylodesis for the treatment of adult pyogenic spondylodiscitis.
Most adult patients with pyogenic lumbar or thoracic spondylodiscitis are treated with an external orthosis and antimicrobial therapy for several weeks to months. If surgical intervention is required, a combined anterior and posterior approach for debridement and fusion with autologous bone graft or titanium mesh cage is usually performed. ⋯ We conclude that minimally invasive percutaneous fixation is a feasible and effective technique to achieve immediate pain release, avoid long-term immobilization and overcome the disadvantages of a dorsoventral procedure. However, surgical complications and possible follow-up procedures supplement the patients' risks of adverse reactions of the disease.

Dural suturing for repair of cerebrospinal fluid leak in transnasal transsphenoidal surgery.
Repair of a cerebrospinal fluid (CSF) leak after transsphenoidal surgery (TSS) is usually accomplished using various graft materials. These methods are effective in most, but not all, cases. ⋯ Direct suturing of the sellar dura is a simple, safe, and reliable surgical technique for repairing CSF leaks after TSS. Using this procedure, more than 70% of patients with an intraoperative CSF leak can avoid autologous tissue grafts.

Significance of serial S100b and NSE serum measurements in surgically treated patients with spondylotic cervical myelopathy.
Predicting functional outcome following surgery performed for spinal cord compression is still a considerable problem. Recent observations, though, strongly suggest that with serial measurements of serum S100b, this might be possible in patients with subacute spinal cord compression. The aim of this study was to examine whether this potential significance of S100b applies as well to patients with spondylotic cervical myelopathy. A further purpose was to assess the value of NSE in this regard, another biochemical marker widely used to monitor cerebral lesions. ⋯ Serial S100b serum measurements do not permit prediction of functional outcome in patients with spondylotic cervical myelopathy in case of an uncomplicated postoperative course. In complicated courses with postoperative deterioration, such measurements reflect postoperative events with possibly prognostic relevance. NSE does not have any significance in these patients with chronic lesions of the spinal cord.

Case ReportsMultidrug-resistant Acinetobacter baumannii ventriculitis: successful treatment with intraventricular colistin.
Acinetobacter baumannii has emerged as an important nosocomial pathogen that can cause a multitude of severe infections. In neurosurgical patients the usual presentation is ventriculitis associated with external ventricular drainage. ⋯ We review the literature concerning intraventricular use of colistin (polymyxin E) for A. baumannii ventriculitis and add three cases successfully treated with this method. Our experience suggests that intraventricular colistin is a potentially effective and safe therapy for the treatment of multidrug-resistant A. baumannii central nervous system infections.
