Supraclinoid blister aneurysms (BAs) of the internal carotid artery are uncommon and deadly, and appropriate treatment is controversial. Endovascular reconstruction may allow treatment through aneurysm isolation. We report a single-institution experience in the use of Enterprise stent-assisted coiling (ESAC) for treating BAs to appraise the safety and efficacy of this technique. ⋯ ESAC to treat BAs is safe, effective, and provides good clinical outcomes. ESAC with telescoping stents has a higher follow-up complete occlusion rate compared with ESAC with single stents.

To minimize surgical morbidity, surgeons may opt to perform segmental limited surgery instead of fusion extension for adjacent segment disease (ASD) after lumbar fusion surgery. This study evaluated clinical outcomes from segmental limited surgery without fusion extension for ASD and assessed which clinical factors were associated with reoperation after segmental limited surgery. ⋯ Segmental limited surgery as a treatment for ASD after lumbar fusion surgery is likely to fail frequently and result in a high rate of recurrent radiculopathy and revision surgery. Fusion extension surgery is especially recommended for ASD at the lowermost mobile segment owing to the high failure rate.

Postoperative central nervous system infections (PCNSIs) are serious complications following neurosurgical intervention. We previously investigated the incidence and causative pathogens of PCNSIs at a resource-limited, neurosurgical center in south Asia. This follow-up study was conducted to analyze differences in PCNSIs at the same institution following only one apparent change: the operating room air filtration system. ⋯ The rates of PCNSI and positive CSF culture were significantly lower in our present cohort compared with the cohort in our previous study. The sole apparent change involves the air filtration system inside the neurosurgical operating rooms; this environmental change occurred during the 5 months between the 2 studies. This study demonstrates the impact of environmental factors in reducing infections.

The transoral approach provides the most direct exposure to extradural lesions of the ventral craniovertebral junction. The morbidity and mortality from this approach greatly limits its use because they are still feared and debated. Using univariable and multivariable logistic regression analyses, this study aims to identify the factors associated with short-term complications in patients undergoing the transoral approach. ⋯ To reduce complications, it is essential to be aware of and to manage these preoperative risk factors. In such manner, we insinuate that postoperative complications depend on the surgeon's familiarity with the transoral approach.
