Case ReportsDecompression procedure using a microendoscopic technique for thoracic myelopathy caused by ossification of the ligamentum flavum.
Microendoscopic discectomy (MED) is one of the minimally invasive endoscopic procedures for treating lumbar disc herniation. The aim of this case report is to describe a patient with thoracic ossification of the ligamentum flavum (OLF) that was completely removed using the microendoscopic technique. ⋯ The authors found that the microendoscopic technique could be applied to decompression surgery for thoracic OLF. The procedure could provide a sufficient decompression with minimum damage to the paraspinal muscles. However, the microendoscopic procedure should be indicated only for select thoracic OLF, such as OLF without fusion at the middle of the spinal canal and OLF without dural ossification, because of its technical difficulties.

Individualized pterional keyhole clipping surgery based on a preoperative three-dimensional virtual osteotomy technique for unruptured middle cerebral artery aneurysm.
Individualized surgical simulation using three-dimensional (3D) imaging to allow safe performance of clipping surgery for unruptured middle cerebral artery (MCA) aneurysm via pterional keyhole mini-craniotomy was performed in 100 consecutive patients. ⋯ Pterional keyhole clipping surgery based on careful surgical simulation with 3D images is a safe and less invasive means to treat relatively small unruptured MCA aneurysms.

Case ReportsStereotactic brainstem biopsy in a patient with coagulopathy of unclear etiology: case report.
Parenchymal hemorrhage is one of the most feared risks of stereotactic brain biopsies potentially resulting in neurological deficits or even a fatal outcome. Patients with disorders of the coagulation system are at particular risk, so identifying these is one of the main tasks prior to surgery. Some patients may have a bleeding tendency despite normal laboratory values of the hemostatic system. ⋯ A medication scheme with tranexamic acid and desmopressin effectively decreased the patient's bleeding time in vivo and the procedure was carried out without complications.
