Trials in thrombectomy for acute ischemic stroke: Describing the state of clinical research in the field.

Background: Endovascular thrombectomy has revolutionized treatment of ischemic stroke. Given the clinical and socioeconomic support for thrombectomy, new devices, procedures, and pharmaceuticals have emerged in recent years, and have been subject to a growing number of clinical trials worldwide.

Objective: To define the current state of thrombectomy clinical trials, highlight recent trends, and help guide future research in this area.

Endoscopic removal of recurrent colloid cysts.

Objective: Removal of colloid cysts of the third ventricle using a purely endoscopic method has been established as a safe and advantageous technique. It is hypothesized that endoscopic removal in recurrent cases might pose more technical challenges and result in less success. The objective of this study was to assess the feasibility and outcomes of using a purely endoscopic approach for the management of recurrent colloid cysts compared to primary cysts.
