Background: Oculomotor nerve palsy (ONP) is a common symptom of posterior communicating artery aneurysm (PcomAA) that can lead to impaired eye movement and pupil dilation. Currently, surgical clipping and endovascular embolization are the two most popular treatment methods for PcomAA-induced ONP; however, the recovery outcome between the two methods remains to be elucidated.
Methods: In the present study, we thoroughly compared the pretreatment factors and recovery outcome of the two treatments on 70 patients with PcomAA-induced ONP. The patients were separated into two groups based on the treatment that was received. Pretreatment factors, including age, sex, time period between ONP onset and treatment, ONP type, aneurysm diameter, status of subarachnoid hemorrhage and aneurysm rupture were recorded for each individual patient. Recovery outcome of the patients was assessed over a 12-month period.
Results: No significant differences were observed in any of the analyzed factors. Importantly, we revealed a significantly higher full recovery rate for the patients receiving the surgical clipping treatment than the ones that received the endovascular embolization treatment. In addition, we showed that patients' age was negatively correlated with the recovery extent in both treatment groups.
Conclusions: The outcome of our study suggests that surgical clipping might be a better option to treat PcomAA-induced ONP.

The traditional posterior median approach laminectomy is widely used for lumbar decompression. However, the bilateral dissection of paraspinal muscles during this procedure often leads to postoperative muscle atrophy, chronic low back pain, and other complications. The posterior midline spinous process-splitting approach (SPSA) offers a significant advantage over the traditional approach by minimizing damage to the paraspinal muscles.

The solder burrs on the 304V wire surface can easily scratch the vascular tissue during interventional treatment, resulting in complications such as medial tears, bleeding, dissection, and rupture. Abrasive blasting is often used to remove solder burr and obtain a smooth surface for the interventional device. This study conducted an abrasive blasting experiment to explore the effects of process parameters (air pressure, lift-off height, abrasive volume, and abrasive type) on processing time, surface roughness, and mechanical properties to reveal the material removal mechanism.
