RECENT UPDATE ON DOGBONING EFFECT

DB is bacially a condition in which the ends of an object extend or protrude beyond its center. The differential expansion induces increased mechanical stress and damage to the vascular wall at the terminal, resulting in possible complications including vascular wall injury and in-stent restenosis. Overstretching at the stent ends may lead to mechanical damage to the blood vessel, thereby elevating the risk of thrombosis and intimal hyperplasia, which adversely affects the long-term efficacy of the stent implant. Minimizing this effect enhances the uniformity of stent expansion, decreases vessel injury, and leads to improved clinical outcomes for patients undergoing stent placement. Consequently, the reduction of the dogboning effect is significant from a mechanical standpoint, as it pertains to the radial support that the stent offers to the artery. Hence, in this review, we have discussed about different studies that had introduced newer design & future strategies to minimum DB.
