Restenosis
- Restenosis can occur in the implanted stent after performing PCI.[1]
- Factors such as stent type, chosen procedure, and patient-related factors are critical in the pathophysiology of stent thrombosis or restenosis.[2][3]
- In the setting of in-stent restenosis (ISR) after bare metal stent (BMS) implantation, the risk of recurrence can be predicted by the pattern of restenosis.
Classification
Table 1. Mehran Classification System[4]
- Pattern I: Focal (≤ 10 mm in length) lesions
- Ia : Restenosis within the stent
- Ib : Restenosis at the edge of the stent
- Ic : Restenosis at the articulation or gap
- Id : Restenosis multifocal
- Pattern II: ISR >10 mm within the stent
- Pattern III: Includes ISR > 10 mm extending outside the stent
- Pattern IV: ISR totally occluded
Implications
- The need for recurrent target lesion revascularization (TLR) increased with increasing ISR class, increasing from 19%, 35%, 50%, to 83% in classes I to IV, respectively (P <0.001)[4].
- Restenosis after drug eluting stent implantation is generally more focal than following bare metal stent placement[5][6], and, with the sirolimus eluting stent, more is commonly at the margin of the stent due to balloon injury that is not covered with stent[5][6][7].
