Abstract

Rationale:

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.

Diagnose:

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

Interventions:

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

Outcomes:

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

Lessons:

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