Comparative StudyThe Claw Sign: An angiographic Predictor of Recanalization After Mechanical Thrombectomy for Cerebral Large Vessel Occlusion.
Mechanical thrombectomy undoubtedly improves functional outcomes for patients with acute ischemic stroke. Although we have observed occlusion sites that protrude proximally into the vessel on angiography, termed the "claw sign," we have been unable to state its clinical significance. In this study, we aimed to determine whether the presence of a claw sign was related to recanalization success after mechanical thrombectomy. ⋯ The presence of the claw sign might predict successful recanalization in patients undergoing mechanical thrombectomy for large vessel occlusion.

Case ReportsSpinal Cord Infarction due to Fibrocartilaginous Embolism: A Report of 3 Cases.
Fibrocartilaginous embolism (FCE) is an uncommon cause of spinal cord infarction often misdiagnosed as transverse myelitis. The mechanism of ischemia is suspected to be due to retrograde embolization of nucleus pulposus material originating from Schmorl's nodes to the spinal vessels following acute disk herniation. We describe the clinical and imaging findings of FCE in 3 healthy young women with history of trivial spinal cord trauma, and recommend that FCE should be considered in the differential diagnosis of acute myelopathy.
