Symptomatic lumbar juxta facet cysts (ganglion and synovial cysts) (JFC) are uncommon lesions of the spine, causing radiculopathy and low back pain. The authors present their experiences with microsurgically treated JFC. This rare pathology is discussed with special focus on therapeutic concepts and long-term outcome. ⋯ Adequate and definitive treatment in symptomatic JFC consists in microsurgical resection. A partial hemilaminectomy is sufficient for surgical exposure. Excellent long-term outcome can be achieved. Recurrences and surgical complications are rare.

Case ReportsSurgical strategies for treatment of giant or large intracranial aneurysms: our experience with 139 cases.
Giant or large intracranial aneurysms are the vascular neurosurgeon's greatest challenge. At our department, we have treated one hundred and thirty nine patients with giant or large intracranial aneurysms between 1975 and 2001. These included 37 partially thrombosed giant aneurysms. 75 aneurysms were giant (> 2.5 cm) and 64 were large aneurysms (2-2.5 cm). ⋯ While selecting surgical strategy for partially thrombosed giant aneurysm, securing the neck is most important. If the neck is too narrow to reconstruct, aneurysmectomy with anastomosis is one of the surgical strategies. An extracranial intracranial bypass should be considered in cases where clipping or parent artery ligation is expected to be associated with compromise of cerebral circulation.

Factors leading to hydrocephalus after aneurysmal subarachnoid hemorrhage.
Hydrocephalus is not a rare complication following aneurysmal subarachnoid hemorrhage. Hydrocephalus following subarachnoid hemorrhage can progress acutely (0-3 days), subacutely (4-13 days) or chronically (after 13 days). The predisposing factors leading to hydrocephalus after subarachnoid hemorrhage are not known exactly. ⋯ Fifty-five percent of patients with hydrocephalus were graded as 3 and 4 according to Fisher grade on initial CT scan. Preexisting diabetes, higher Fisher grade and intraventricular hemorrhage were statistically significant predictors for the development of hydrocephalus. But only preexisting diabetes and higher Fisher grade were independent predictors according to multivariate analyses.
