Dual Stenting with New Generation Stents for Aneurysm Embolization in Acute Subarachnoid Hemorrhage.
Endosaccular treatment is the backbone of endovascular treatment for acutely ruptured aneurysms. Stent-assisted coiling is a niche technique in this context. Data on X-stenting or Y-stenting (dual crossing stenting, DCS) in the acute phase after subarachnoid hemorrhage (aSAH) are scarce, and the impact of stent properties on the outcome is unknown. We retrospectively evaluated the clinical and imaging results of DCS in patients treated for aSAH. ⋯ Our findings and the patient-by-patient data we extracted from the literature suggest that DCS can be performed with new-generation, low-profile stents in aSAH if a definite procedural risk is acceptable for a specific patient. New-generation open-cell stent combinations appear as a viable choice for DCS in aSAH.

To review our use of pharmacologic provocative testing (PT) and intraoperative neurophysiologic monitoring (IONM) during endovascular embolization for eloquent arteriovenous malformations (AVMs), and better define their clinical utility. ⋯ PTs and IONM are valuable techniques to predict neurologic deficits and improve procedure decision-making during AVM embolization under general anesthesia. A 5-mg dose of propofol may be sufficient for PTs in larger-sized feeders and a 3-mg dose may be sufficient in smaller-sized feeding branches.

We investigated the frequency of postoperative major complications, length of stay (LOS), and associated risk factors for primary C2-involved upper cervical chordoma through the combined anterior retropharyngeal-posterior approach. ⋯ Patients who are older, experience longer operative duration, or have larger tumor extension have a greater risk of postoperative major complication. The LOS can be predicted by age, preoperative neurological deficit, CZH classification, surgical approach, and surgical duration. Accordingly, patients with these risk factors should be monitored and targeted with preventative measures.

The current study aimed to assess the risk factors and preventive measures for valve inversion after lumboperitoneal shunt (LPS) construction. ⋯ The distance between the valve and spinous process was found to be significantly correlated with valve reversal. However, the condition can be prevented by fixing the tube at the nuchal ligament.

To determine those clinical, demographic, and operative factors that predict 30-day unplanned reoperation and readmission within a population of adults who underwent spinal metastasis surgery at a comprehensive cancer center. ⋯ Increasing medical comorbidities is independently predictive of both 30-day unplanned readmission and reoperation after spinal metastasis surgery. Unplanned reoperation is also positively predicted by a longer index admission. Neither tumor pathology nor age predicted outcome, suggesting that poor wound-healing factors and increased surgical morbidity may best predict these adverse outcomes.
