We investigated the complication rates of balloon-assisted coil embolization of ruptured and unruptured cerebral aneurysms dependent on their morphologic characteristics in angiography. ⋯ The risk of periprocedural complications in balloon-assisted coil embolization of ruptured and unruptured cerebral aneurysms is linked to the morphologic presentation of the aneurysm; the complication rate was significantly higher in bifurcation aneurysms.

The craniocervical junction is a complex anatomic location that contains the occipital bone, atlas, axis, and important complex ligamentous structures. The stability of this region is ensured only with the help of ligaments. ⋯ The occiput should not be involved in the fusion area when the alar ligaments are preserved during surgery for a C2 lesion.

To evaluate the outcome of posterior open reduction and interlaminae compression fusion using a screw-rod system combined with a structural iliac bone graft in the treatment of atlantoaxial dislocation (AAD) secondary to os odontoideum. ⋯ Intraoperative open reduction and interlaminae compression fusion using a posterior screw-rod system combined with a structural iliac bone graft is a safe and effective procedure for AAD secondary to os odontoideum.

In minimally invasive endoscopic port surgery, the medium is air, and the image is clearer than in fluid. The most commonly used port is a single-channel port, which accommodates the rod lens of the endoscope and 2 microsurgical instruments. This setup decreases the freedom of movement of the 3 instruments, making the bimanual procedure difficult. We describe a novel "dual-channel" endoscopic port to facilitate a bimanual refinement procedure for removing deep-seated spontaneous intracerebral hematomas, and we demonstrate the feasibility of this method. ⋯ The dual-channel endoscopic port facilitated bimanual refinement microsurgery during the evacuation of deep-seated intracerebral hematomas, and it prevented the disturbance of the 3 instruments without restraining the scope of the operation during the microsurgical procedure.

Meningiomas are the most common type of benign brain tumor, and the incidence of meningioma in women is more than twofold higher than in men. Several studies have demonstrated that hormones are somehow related to the growth of meningiomas. ⋯ This is the first report of a case in which an LHRH agonist promoted the growth of a pre-existing meningioma. We suggest that patients with a history of meningioma who are receiving LHRH agonist treatment should be closely monitored.
