Diagnostic value of endoscopic ultrasound-guided directional eFLOW in solid pancreatic lesions.

Aim: Ultrasound using microbubble-based contrast agents is useful for vascular imaging. Directional eFLOW (D-eFLOW) is a novel technology for vascular assessment that provides high spatial and temporal resolution. The purpose of this study was to investigate the utility of endoscopic ultrasound (EUS)-guided D-eFlow before and after administration of an ultrasound contrast agent (USCA) for assessing the vascularity of solid pancreatic lesions.

Cardioembolic stroke on unaffected side during thrombolysis for acute ischemic stroke.

Cardiac thrombus is not an established contraindication to thrombolysis with intravenous tissue plasminogen activator in acute ischemic stroke. Recurrent ischemic stroke involving an initially unaffected arterial territory during the course of thrombolysis in stroke has been reported, but remains exceptionally rare. We present a case that developed cardioembolic stroke on the previously unaffected side during thrombolysis for acute ischemic stroke.
