Day-case angioplasty in diabetic patients with critical ischemia

Recent studies have shown that percutaneous transluminal angioplasty (PTA) can be safely performed as a day-case procedure. Many centers consider diabetes mellitus as a contraindication to day-case PTA. In this study, the safety and efficacy of 95 day-case PTA in 66 diabetic patients with critical leg ischemia (CLI) were evaluated.

Diabetic patients with CLI were assessed in a one-stop multidisciplinary outpatient clinic. Sixty-six outpatients with CLI deemed suitable for radiological intervention by non-invasive imaging (ultrasound angiology or magnetic resonance angiography) were scheduled for day-case PTA.

PTA was initially successful in 63 out of 66 patients (95%). In 3 patients (5%), PTA was not possible because the lesion could not be balloon dilated or crossed with a guide wire. Clinically suspected first, second and third re-stenosis confirmed by non-invasive studies occurred in 20 out of 63 (31%), 7 out of 20 (35%) and 2 out of 7 (28%) patients, respectively. Following PTA, debridement was performed in 11 patients (17%), minor amputation in 8 (13%) and major amputation in 3 (5%). Relief of the primary symptom of rest pain or healing of ulcers was achieved in 23 out of 32 (72%) and 25 out of 27 (92.5%) patients, respectively. No peri-interventional morbidity or mortality was encountered.

PTA is feasible and safe as a day-case procedure in diabetic patients with CLI. Re-stenosis can be managed by repeat day-case PTA.
