Case report: intravascular ultrasound sonography-guided re-entry technique in crushed stent.

Crushed stent is a rare complication, being caused by an incorrect passage of the guidewire between the stent's struts and the vessel wall in case of severe underexpansion. In this case, an IVUS-guided re-entry could be an option to gain the stent true lumen and avoid a second stent implantation.
