title: Coronary artery bypass grafting after percutaneous coronary intervention.
abstract: Following percutaneous intervention (PCI), restenosis, progression of disease and multi-vessel involvement may require further intervention in the form of surgical revascularization. Patients with coronary artery bypass grafting (CABG) done after PCI were evaluated to find out the reason for the need of surgical revascularization. Over a period of 12 months, 610 patients underwent CABG. Out of them, 34 patients had previous PCI/stenting. Coronary risk factors including hypertension in 85%, diabetes mellitus in 60%, dyslipidemia in 60%, tobacco use in 50% and a positive family history was present in 53% of the patients. All patients were symptomatic. Multi-vessel disease was present in 67% and single vessel in 4.7%. The extent of disease and stenosis of stents were responsible for reintervention. Careful selection of patients is required in presence of multiple risk factors for coronary artery disease to provide maximum benefit by either PCI or CABG.
