To investigate hemodynamic changes in moyamoya disease (MMD) via two-dimensional cine phase-contrast magnetic resonance imaging and computational fluid dynamics. ⋯ Pressure drop difference, flow rate, and size of PComAs can be used to evaluate impairments in cerebrovascular reserve and indicate long-term prognosis in MMD.

To characterize the learning curve for a single surgeon during his initial phases of performing minimally invasive surgery oblique lumbar interbody fusion. ⋯ Minimally invasive surgery oblique lumbar interbody fusion presents a learning curve to the practicing spine surgeon with regard to operative time, x-ray exposure time, and intraoperative and postoperative complications. Close attention to detail can minimize complications that may be associated with the learning curve.

To compare the clinical outcomes of patients with lumbar disc herniation with bi-radicular symptoms undergoing percutaneous endoscopic lumbar discectomy (PELD) and minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF). ⋯ Both PELD and MIS-TLIF, as treatments for lumbar disc herniation with biradicular symptoms, showed favorable clinical outcomes. Compared with MIS-TLIF, PELD had the following advantages: 1) it is performed under local anesthesia and 2) there is rare possibility of "fusion disease," such as ASD. However, the PELD is also revealed several problems, including a relatively lower success rate and satisfaction, a relative higher rate of postoperative long-term chronic low back pain and the possibility of recurrence, despite the low incidence.

Occasionally, previously coiled aneurysms will require secondary treatment with surgical clipping, representing a more complicated aneurysm to treat than the naïve aneurysm. Patients who initially presented with a ruptured aneurysm may pose an even riskier group to treat than those with unruptured previously coiled aneurysms, given their potentially higher risk for rerupture. The objective of this study was to assess the clinical outcomes of patients who undergo microsurgical clipping of ruptured previously coiled cerebral aneurysms. In addition, we present a thorough review of the literature. ⋯ Microsurgical clipping of previously ruptured, coiled aneurysms is a promising treatment method with favorable clinical outcomes.

Solitary fibrous tumor (SFT)/hemangiopericytoma (HPC) is radiologically difficult to distinguish from meningioma, especially angiomatous meningioma. This study aimed to detect texture parameters to distinguish SFT/HPC from angiomatous meningioma using magnetic resonance imaging texture analysis with commercially available software. ⋯ This study demonstrated that magnetic resonance imaging texture analysis was useful for distinguishing SFT/HPC from meningioma, especially angiomatous meningioma.
