This systematic review and meta-analysis evaluated the risk of intracerebral hemorrhage, and its subtypes associated with mechanical thrombectomy with or without IV thrombolysis for the treatment of acute ischemic stroke due to large-vessel occlusion. The analysis showed that the overall risk of symptomatic intracerebral hemorrhage was comparable between mechanical thrombectomy with IV thrombolysis and mechanical thrombectomy alone.

This study prospectively evaluated the diagnostic accuracy of an optimized CT lumbar spine protocol as a potential alternative to MRI in assessing suspected neural compression. CT accurately identified all cases requiring urgent decompression. CT had 97% sensitivity, specificity, and positive and negative predictive values in detecting disc pathology in patients presenting with symptoms suggestive of acute neural compression compared with MRI.
