Cord signal change (CSC) on magnetic resonance (MR) imaging is an important radiologic feature of degenerative cervical myelopathy (DCM). Occasionally, DCMs correlate with clinical symptoms with no CSC. The aim of this study was to evaluate clinical and radiologic features, depending on the presence of CSC in DCM. ⋯ DCM with negative CSC can be caused by a well-preserved cervical ROM, even with less deteriorated canal stenosis and kyphosis. C27ROM may be a helpful radiologic parameter in diagnosing DCM before CSC appears.

Intraoperative 3-Dimensional Rotational Angiography in Cerebrovascular Surgery: A Case Series.
Intraoperative imaging is critical in cerebrovascular surgery to assess the technical success of the operation. This case series aimed to evaluate the safety and efficacy of 3-dimensional rotational angiogram (3D-RA) in addition to 2-dimensional intraoperative angiography (2D-IOA) during cerebrovascular surgery in the hybrid operating room. ⋯ Using a combination of 3D-RA and 2D-IOA in the hybrid operating room may enhance the likelihood of achieving an optimal result when employing microsurgical cerebrovascular surgery and avoid unanticipated incomplete outcomes, complications, and returns to the operating room. Whereas the addition of 3D-RA elucidated residual aneurysm not otherwise visualized on the 2D-IOA, in other cerebrovascular procedures studied, there was no additional value of the 3D-RA over the 2D-IOA.

Full-endoscopic removal of lumbar juxtafacet cysts: a prospective multicentric study.
Lumbar juxtafacet cysts are benign lesions that grow at the level of facet joints or within neighboring structures. Recently, there is an ongoing trend toward less invasive procedures for treating degenerative spine diseases. Here we report a multicenter study of full-endoscopic surgery for juxtafacet cyst removal. ⋯ Full-endoscopic surgery is feasible and safe for juxtafacet cyst removal. Our results are consistent with findings from recent full-endoscopic and series, with outcomes overlapping those reported for open or tubular techniques.

Currently, it remains controversial about guidelines for the application of low-molecular-weight heparin (LMWH) in patients with acute ischemic stroke (AIS). Therefore this meta-analysis was carried out, aiming to systematically investigate the short-term and long-term safety and efficacy of LMWH in AIS patients. ⋯ To sum up, on the basis of limited studies available currently, the early use of LMWH in AIS patients aged older than 70 years should be cautious because it may increase the risk of all-cause mortality. For patients younger than 70 years old, the early use of LMWH significantly reduces the short-term risk of DVT, but there is no significant relationship in the long term. In terms of DVT prevention, enoxaparin and danaparoid are probably more effective. Nonetheless, more future randomized controlled trials are warranted to verify and support this conclusion.

Risk factor for poor outcome of the elderly patients with aneurysmal subarachnoid hemorrhage based on the post hoc analysis of modified WFNS study.
There is currently no precise guide for the treatment and management of elderly patients with aneurysmal subarachnoid hemorrhage (aSAH). Thus, the aim of this study was to clarify the factors of poor outcome and mortality in elderly patients with aSAH. ⋯ The mWFNS scale is a useful prognostic predictor for both non-elderly and elderly patients with aSAH. Elderly male patients with aSAH presenting with severe vasospasm should be managed more carefully.
