title: Clinical outcome and prognostic factors for ischaemic ulcers treated with PTA in lower limbs.
abstract: OBJECTIVE
  To analyse the clinical outcome of patients with ischaemic ulcers (Fontaine stage IV) undergoing percutaneous transluminal angioplasty (PTA).
  
  
  METHODS
  Retrospective cohort study of 40 patients (21 males) treated between January 1998 and December 1998. Cardiovascular risk factors, co-morbid, baseline laboratory, angiographic data and technical success were recorded. Patients were followed for a median of 20 (inter quartile range (IQR) 8-26) months.
  
  
  RESULTS
  Cumulative ulcer healing rates at 3, 6, 12, and 24 months were 15, 40, 54 and 81%, respectively. The median time to healing was 5 (IQR 2-7) months. Cumulative restenosis at 1, 3, 6 and 12 months was 3, 10, 29 and 52%, respectively. Nine patients (22%) suffered ulcer reappearance. Lipoprotein (a) serum levels > 30 mg/dl (HR 0.2, 95% CI 0.05-1.0, p = 0.05) and diabetes mellitus (HR 0.2, 95% CI 0.5-0.7, p = 0.01) were associated with delayed ulcer healing.
  
  
  CONCLUSIONS
  PTA leads to ulcer healing in the majority of patients. Elevated lipoprotein (a) levels > 30 mg/dl and diabetes mellitus are independently associated with ulcer persistence.
