Re-perfusion revision surgery for augmented vertebral nonunion with movable cement: A case report.
Osteoporotic vertebral nonunion is a special type of osteoporotic vertebral fracture and can gain satisfactory clinical outcomes using vertebral augmentation. In the rare occurrence that augmented vertebral nonunion occurs postoperatively, pedicle screw fixation is the primary strategy. However, is a different method like the second shot of cement reliable? The purpose of this study is to introduce the reperfusion revision surgery strategy for treatment of osteoporotic vertebral nonunion. ⋯ The patient gained immediate pain relief and vertebral stability after the revision surgery. A 2-year postoperative radiograph and follow-up showed sufficient vertebral height and clinical outcomes. Using special puncture and bone cement perfusion techniques, reperfusion revision surgery in situ is an effective strategy for the treatment of vertebral re-nonunion.

Complete transection of optic nerve after endovascular coiling of a large ophthalmic artery aneurysm: Case report.
We describe a patient who developed delayed blindness of the left eye at 5 weeks after endovascular coiling of a large ophthalmic aneurysm. ⋯ This report describes a rare complication of a sudden increase in size of a large ophthalmic aneurysm despite successful endovascular occlusion.

Jarcho-Levin syndrome (JLS) is a rare congenital disorder characterized by different clinical and radiologic findings. The disease was first reported by Jarcho and Levin in 1938, and it was described as the presence of various malformations or abnormal fusion in the thoracic vertebrae and ribs, short trunk, and respiratory distress. ⋯ JLS may affect cells derived from the neural crest located between the neural tube and surface ectoderm. Therefore patients with JLS should be screened for other tumors located in this area.

Little literature is available on mechanical thrombus aspiration in acute ischemic stroke with coincident ipsilateral unruptured aneurysm, especially with aneurysm proximal to the occlusion site. In this report, we describe a case of ischemic stroke in a patient with acute occlusion of M1 segment of the middle cerebral artery with coincident ipsilateral internal carotid artery-posterior communicating artery aneurysm who was successfully treated by mechanical clot retrieval using the Sofia (6F) PLUS technique (MicroVention Terumo, Tustin, California, USA). ⋯ Ischemic stroke patients with coincident aneurysm are at increased risk of aneurysmal rupture and should be managed with tailored endovascular strategies. Our case shows that a direct aspiration first pass technique using the Sofia (6F) PLUS catheter provides a safe, effective approach for thrombus aspiration in stroke patients.

The effectiveness of tumor control after Gamma Knife radiosurgery (GKS) for intracranial meningioma is well established. Moreover, GKS is an alternative to reduce surgical-remnant meningioma recurrence. Nevertheless, the tumor can recur even after GKS and is associated with its histologic malignancy. We here investigated the risk factors associated with recurrence from remnant lesions after GKS, assessing recurrence patterns according to histological grades. ⋯ The study findings indicate that the post-GKS meningioma recurrence likelihood is high when the meningioma has malignant histologic features. In addition, considering the recurrence patterns, it is important to define a precise target for GKS.
