In-hospital complication rates after stent treatment of 388 symptomatic intracranial stenoses: results from the INTRASTENT multicentric registry.

Background And Purpose: Stenting is increasingly used as an adjunct to medical therapy in symptomatic intracranial stenoses. High periprocedural adverse event rates are one of the limitations of endovascular treatment. Data from the INTRASTENT multicentric registry should demonstrate in-hospital complications at the current stage of clinical development of the stent procedure.

Crimping and repositioning of a maldeployed balloon-expandable arterial stent using a gooseneck snare.

Purpose: To describe a technique for repositioning a fully deployed iliac stent from the infrarenal aorta into the common iliac artery (CIA).

Case Report: A 58-year-old man was undergoing treatment for a significant right CIA stenosis when a 7x24-mm Palmaz Genesis medium stent was mistakenly deployed in the infrarenal aorta. With the stent still over the guidewire, an 8x60-mm balloon catheter was placed coaxially in the stent.
