Objectives and Background: Intrastent restenosis (ISR) is an unsolved problem of coronary interventions. Its incidence and treatment outcomes come mainly from controlled trials, but the data from daily practice is not well known and could be relevant when deciding to use drug eluting stents. We present the incidence, treatment strategy and clinical follow-up of ISR in our daily routine interventional activity. Methods and Results: Between October 1998 and April 2000, we implanted 1,950 stents in 2,650 lesions in 1,533 patients. In the study period, 111 (7.2%) patients manifested ISR >60%, in 159 lesions. Of those, 109 lesions were treated with PCI (4% of the total number of treated lesions) in 80 patients; with surgery 19 (13 patients) and 31 (29 patients) medically. In 82% the IRS was a first time restenosis, 15% the second ISR, and 2.5% the third time. In the 109 lesions treated with PCI, the cutting balloon was used in 18 lesions (16.5%), rotational atherectomy in 22 (20%), balloon in 41 (38%) and stent in 26 lesions (24%). 64 ISR were in vessel < 2.75mm (40%), and 66 ISR were > 10 mm long (61%). Mortality rates were 0.9%, 0%, 0% and 3%, at the time of the procedure and at the first month, then 6 and 12 months. The percentage of readmission due to ischemia was 5, 27 and 27% and the targeted vessel revascularization 0, 11 and 21% at 1, 6 and 12 months. Patients were better or asymptomatic in 93, 80 and 76% respectively at 1, 6 and 12 months. Conclusions: The treatment of ISR based on clinical follow-up involved a low percentage of interventional activity, but in this group of patients with clinical diagnosis of ISR the percentage of rehospitalization is over 40% per year, the majority of the restenosis cases present lesions of more than 10 mm in length on vessels less than 2.75 mm.
