New Stent Implantation for Recurrences After Stenting for In-Stent Restenosis

Peri-Stent Abluminal Hematoma and Pin-Hole Balloon Rupture During Treatment of Calcified Drug-Eluting Stent In-Stent Restenosis

“…Furthermore, although consequences of balloon rupture in native lesions are well established, 6 the occurrence of this complication in patients with ISR is very rare. 1- 4 The present findings suggest that in patients with old ISR the presence of neoatherosclerosis and, in particular, the presence of calcification within the stent, should be ruled out. When calcified ISR is detected on OCT, usage of non-compliant balloons would be better to prevent pin-hole balloon rupture.…”

“…3 In contrast, many patients with ISR present with underexpanded stents. 4 This problem may be a result of poor stent deployment or the presence of underlying undilatable calcified lesions. 4 In the latter scenario severe stent underexpansion may be very difficult to correct despite the use of noncompliant balloons and high dilation pressures.…”
