Comparative Study
Clinical and Radiologic Outcomes of Direct Versus Indirect Decompression with Lumbar Interbody Fusion: A Matched-Pair Comparison Analysis.
To compare the radiologic and clinical outcomes between oblique lumbar interbody fusion (OLIF) without laminectomy and minimally invasive transforaminal lumbar interbody fusion (MI-TLIF). ⋯ OLIF may achieve equivalent clinical and radiologic outcomes compared with MI-TLIF when the stenosis is minimal because the decompression performed is indirect. Furthermore, the OLIF shows less blood loss and shorter operative time, better restoration of DH, and earlier time to fusion than the MI-TLIF.

Thoracic ossification of the ligamentum flavum (OLF) is a common cause of thoracic myeloradiculopathy. Thoracolumbar kyphosis derived from abnormal embryonic development of the spine vertebrae often progresses continuously and causes neurologic deterioration. These conditions are presented separately in most cases. A diagnosis of both OLF and thoracolumbar kyphosis in the same patient is rare, and no definite principle of surgical strategy for this case could be found in the literature. ⋯ For patients with thoracic OLF and thoracolumbar kyphosis derived from wedged vertebrae, 1-stage laminectomy and kyphosis correction has a risk that may lead to a negative outcome. Staging operation should be taken into consideration when planning a surgical strategy for the treatment of kyphosis associated with concurrent compressive myelopathy.

Hematologic inflammatory markers are simple, inexpensive prognostic markers for various conditions. The prognostic significance of the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), and red blood cell distribution width (RDW) has been shown in a variety of tumors. We evaluated the prognostic value of these markers in glioma. ⋯ A high preoperative NLR, PLR, and MLR was predictive of a poor prognosis for patients with glioma. NLR was an independent prognostic factor for OS in patients with glioma.

Case Reports
Treatment of symptomatic dolichoectatic vertebrobasilar aneurysms: a single-centre experience in 12 patients.
To report our single-center experience in the treatment of dolichoectatic vertebrobasilar aneurysms. ⋯ If the condition of the patients is stable and benign, they can be treated with medication or stent reconstruction. Given the serious complications that can be caused by open surgery, care must be taken when selecting the patients to be treated using open surgery, but more studies are needed to support this conclusion. The key points are to avoid aneurysm thrombosis and maintain patency of the perforators.

Case Reports
Rupture of a Giant Anterior Sacral Meningocele in a Patient with Marfan Syndrome: Diagnosis and Management.
Marfan syndrome is a genetic disorder that results in the weakening of connective tissues. Dural ectasia has been defined as a feature of Marfan syndrome and is present in up to 92% of patients. Rarely, dural ectasia can erode through the sacrum expanding into an anterior sacral meningocele. ⋯ The progression of dural ectasia in Marfan syndrome to an anterior sacral meningocele is uncommon. It is important to identify the characteristics associated with an expanding dural ectasia as this patient's symptoms progressed over time and the meningocele grew large. Given its rarity, there are no guidelines in place regarding size at which repair of an anterior sacral meningocele should occur prophylactically. It is important to review these cases in order continue to learn about progression, management, and outcomes of patients with an anterior sacral meningocele.
