Microsurgical clipping of aneurysms demands precise spatial understanding of aneurysm morphology and vascular geometry. We analyzed the impact of preoperative three-dimensional (3D) angiographic imaging on clinical and angiographic outcome after clipping of ruptured intracranial aneurysms. ⋯ In our study, accurate operation planning using 3D angiography was associated with a lower ischemic complication rate after clipping of ruptured intracranial aneurysms, which may potentially influence clinical outcome.

To analyze postoperative changes in cervical alignment in patients with adolescent idiopathic scoliosis (AIS) with different curve patterns. ⋯ Correlations between the improvement of CL and TK highlight the importance of restoration of patients with normal TK or AIS. Reciprocal changes in cervical alignment may happen if the TK was also simultaneously restored in patients with AIS. For patients with different curve patterns, the cervical sagittal parameters tend to be similar during follow-up.

The need for lumbar-lumbosacral fusion surgery has increased in the recent decade. Although this type of surgical approach has been reported to provide better improvement in low back pain compared with conventional conservative treatments, the ratio of failure varies between 5% and 30% in different studies. ⋯ Our study has revealed that lumbosacral fusion surgery increases sacroiliac joint degeneration. We consider that magnetic resonance imaging is superior to computed tomography for detection of early stage sacroiliac joint degeneration.

We elucidated the clinical and radiological characteristics and analyzed the risk factors for hemorrhage and poor outcomes of cerebral venous malformations (CVMs) in a northern Chinese population. ⋯ Our results have shown that conservative treatment of CVMs results in a relatively good prognosis. For those complicated by hemorrhage or cavernous angiomas requiring surgical interventions, the integrity of the CVM should be preserved, irrespective of the treatment. In exceptional cases, before CVM resection, the CVM drainage should be comprehensively evaluated.

Cerebellar liponeurocytoma (cLNC) is a rare benign glioneuronal tumor with only ~60 cases reported since its first description in 1978. They have occurred largely as sporadic cases; however, familial cases with possible autosomal dominant inheritance have also been reported. Surgical excision has been considered the main modality of treatment, even for recurrent lesions. Uncertainties exist regarding the natural history, long-term outcomes, and optimal postoperative management and follow-up protocols for cLNC in general and multifocal cLNC in particular. Multifocality is exceedingly rare, with only 4 cases reported previously. ⋯ Surgical excision forms the cornerstone of management of cLNCs. However, it is necessary to vigilantly monitor these patients owing to the high recurrence rates of cLNC despite the innocuous histologic features.
