Self-expanding stents are typically utilized in cases where the lesion is irregular. This type of stent is designed to expand automatically once deployed, adapting to the shape of the lesion, which is particularly useful for addressing complex geometries. Irregular lesions can present challenges for traditional stenting techniques, but self-expanding stents provide flexibility and the ability to conform to the anatomy, helping to maintain patency in varying luminal shapes.

Utilizing self-expanding stents in such scenarios enhances their effectiveness in achieving long-term results, especially in anatomic regions where other stent types might not fit as securely or effectively. This adaptability is what makes them particularly valuable in interventions involving irregularly shaped lesions, maximizing the therapeutic outcome and minimizing complications associated with stent placement.
