During percutaneous coronary intervention of the left anterior descending coronary artery, a lumen narrowing was observed proximal to the stent just deployed. Intravascular ultrasound showed a hematoma localized outside the trilaminar wall structure in absence of a dissection flap or evidence of compression of the lumen. The luminal narrowing resolved after intracoronary administration of vasodilators. This finding is compatible with a coronary spasm triggered by an adventitial hematoma following stent deployment.
