Treatment of longitudinal stent compression under intravenous ultrasound guidance: A case report

Longitudinal stent compression is a rare phenomenon, which has been increasingly reported in recent years.

Patient concerns:

Following 2 stents implanted into the middle and proximal segments of the left anterior descending (LAD) artery, longitudinal stent compression occurred when a post-dilation balloon was introduced into the proximal stent opening.


The intravenous ultrasound (IVUS) examination revealed overlapping at the opening of the proximal stent and poor stent adherence.


Another balloon was carefully inserted into the opening for post-dilation, followed by angiography and IVUS examination.


The IVUS examination indicated that the overlapping at the opening of the proximal stent was improved and the stents were well adhered.


Such compression may be prevented by gentle and careful balloon maneuverability and improved with the use of additional balloon angioplasty or stent implantation.
