Abstract
Very limited data on percutaneous transluminal coronary angioplasty in patients with chronic renal failure is available. We describe the short‐ and long‐term results of percutaneous transluminal coronary angioplasty (PTCA) in a group of seven patients undergoing chronic dialysis. Percutaneous transluminal coronary angioplasty was undertaken because of poorly controlled symptoms in five patients and reversible defects on thallium scintigraphy prior to major surgery in two patients. There were five men and two women, the mean age was 51 years (range 36–75). Six patients were on hemodialysis and one was receiving peritoneal dialysis. All seven patients had complicated baseline coronary stenosis morphology (AHA/ACC Class B‐1). Percutaneous transluminal coronary angioplasty was successful in four patients (57%) and associated with complications in two patients (29%) including one death. Surviving patients were followed for a mean of 6 months (range 3–23 months). Of three surviving patients with initially successful PTCA, two developed restenosis. All three patients with unsuccessful PTCA underwent bypass surgery with one late death. Patients with chronic renal failure compose a high risk population for PTCA with a reduced success rate, an increased complication rate, and a high restenosis rate.
