Pseudoarthrosis after spinal fusion is an important cause of pain, neurologic decline, and reoperation. ⋯ These findings strongly associate several diagnoses with the development of pseudoarthrosis. However, further prospective studies are warranted to establish causation.

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.

The impact of obesity on global spinopelvic alignment is poorly understood. This study investigated the effect of body mass index on achieving alignment targets and compensation mechanisms after corrective surgery for adult spinal deformity (ASD). ⋯ After surgery, obese patients were undercorrected, showed more residual malalignment, recruited more pelvic shift, and had a greater global sagittal angle and worse HRQL scores. The benefits from age-adjusted alignment targets seem to be less substantial for obese and overweight patients.

Sex has been known to significantly affect postoperative complications and length of stay after elective anterior cervical fusions. Current evidence on lumbar spine surgery is limited. ⋯ Contrary to literature on cervical fusions, we found that female sex was independently tied to an increased risk of adverse outcomes after elective posterior lumbar fusion. The results from the study suggest that women may benefit from close surveillance during the postoperative period to minimize risk of complications and subsequent resource utilization in this group.

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.
