Answer

Vessel disruption, [100] displacement of stent, [100, 106, 108, 113, 124] stent fracture, [125] and aneurysms [104, 106] are rare but do occur. Balloon rupture that results in inadequate stent expansion and stent migration has been reported but may be prevented by avoiding curvature of the balloon or stent assembly, the use of newer stents with less injurious ends, and the use of BIB catheters. [99, 113]

Because of the large size of the sheath required, loss of pulse and bleeding from a puncture site may occur. Use of vascular closure devices may help circumvent this problem. Rare complications included myocardial infarction and retroperitoneal hemorrhage.
