BACKGROUND: The leading cause of failure of a prosthetic arteriovenous hemodialysis-access graft is venous anastomotic stenosis. Balloon angioplasty, the first-line therapy, has a tendency to lead to subsequent recoil and restenosis; however, no other therapies have yet proved to be more effective. This study was designed to compare conventional balloon ...

BACKGROUND AND PURPOSE: In acute basilar artery occlusion, intra-arterial thrombolysis or endovascular mechanical recanalization may result in higher recanalization rates than intravenous thrombolysis. However, many patients are admitted to community hospitals, where endovascular therapy is usually not readily available. We initiated a "drip, ship, and retrieve" cooperative treatment protocol in ...
