A pre-catheterization profile was performed and a radial approach with a 5 fr tiger non-medtronic catheter.The left coronary system showed no significant lesions, but mehran type iii in-stent restenosis (isr) was noted in the ostio proximal rca stent.Pci was performed using a mdt guide catheter (6f judkins 3.5) and a sprinter legend balloon (2 x 10mm).Post dilatation showed a longitudinal homogenous opacity moving from the proximal rca and embedded into the distal rca, causing timi 0 flow.An attempt to disintegrate the thrombus via balloon manipulation failed.Thrombosuction was successfully performed and flow restored across the rca.The ostio proximal rca was stented using a non-mdt stent.It was reported that most likely aggressive manipulation of the 6f fr judkins right catheter must have triggered the ostial rca dissection, leading to its total occlusion.Patient was discharged after 48 hours.
