Clinical Outcomes of Self-Made Polyurethane-Covered Stent Implantation for the Treatment of Coronary Artery Perforations

Figure 3

Example of coils and self-made PU-CS implantation to seal a grade II coronary perforation located in the collateral of LCX. (a) CAG reveals LCX-CTO lesion and the collateral vessel of LCX (arrow). (b) CAG shows the coronary perforation in the collateral of LCX caused by guidewire and balloon dilation (arrow). (c) CAG depicts the deployment of two coils (Cook 2.0 × 2.0 mm) (arrow). (d) CAG demonstrates the existing extravasation after coil implantation in the collateral of LCX and stent implantation (Synergy 2.5 × 38 mm & 3.0 × 16 mm) in LCX (arrow). (e) CAG presents the deployment of the self-made PU-CS (2.5 × 18 mm) in the distal segment of LCX to occlude the collateral perforation (arrow). (f) Final angiography after successful implantation of CS. PU-CS = polyurethanecovered stent; LCX = left circumflex coronary artery; CAG = coronary angiography; CTO = chronic total occlusion.
