Long-term mortality and its predictors in patients with critical leg ischaemia

The final outcome of primary infrainguinal percutaneous transluminal angioplasty in 100 consecutive patients with chronic critical limb ischemia.

PURPOSE: To review percutaneous intentional extraluminal recanalization (PIER) for treatment of patients who are poor candidates for infrainguinal arterial bypass surgery (IABS) and have arterial occlusions and chronic critical limb ischemia (CCLI). MATERIALS AND METHODS: Patients with CCLI who were poor candidates for IABS were candidates for PIER. PIER was performed to create continuous arterial flow to the foot for limb salvage. PIER was attempted in 40 patients (22 men, 18 women; median age, 69 years; age range, 44–87 years). Of these patients, 24 (60%) had diabetes, 17 (42%) had renal disease, and 26 (66%) had coronary artery disease. Wound healing was evaluated at follow-up. Kaplan-Meier curves were constructed to evaluate limb salvage, survival, and amputation-free survival. RESULTS: Fifty procedures were attempted in 44 limbs. Tissue loss was present in 40 (91%) limbs, and rest pain was present in four (9%); technical success occurred in 38 (86%). Thirty-seven (84%) of 44 limbs treated with PIER i...

Percutaneous Intentional Extraluminal Recanalization in Patients with Chronic Critical Limb Ischemia

A comparison was made of sirolimus–eluting stents and bare stents as an effective means of treatment of stenosis in crural arteries. Patients were randomly divided into two groups: (1) patients treated with sirolimus-eluting stents and (2) patients treated with bare stents. Each group consisted of 25 patients, and every patient had one stent implanted. All patients showed symptoms of ischemia of the peripheral arteries, classified according to the Rutherford scale into categories 3, 4, and 5. All patients were examined 24 h before and 24 h and 6 months after the intervention. The results were analyzed according to clinical, hemodynamic, and angiographic criteria. Technically, the procedure was successful in 100% of cases, and both groups presented an equal improvement in clinical and hemodynamic parameters. The follow-up angiographic examination demonstrated a significantly lower rate of restenosis among the sirolimus-eluting stent group (4, 16%) versus the bare stent group (19, 76%) (p < 0.001), with lower target lesion revascularization in 3 (12%) versus 14 (56%) (p < 0.05), respectively. Quantitative angiography demonstrated that all variables used to assess restenosis were superior for sirolimus-eluting stents 6 months after intervention: late lumen loss 0.46 ± 0.72 versus 1.70 ± 0.94 (p < 0.001) and minimal lumen diameter 2.25 ± 0.82 versus 0.99 ± 1.08 (p < 0.001). Results of this study reveal that the use of sirolimus-eluting stents decreases the risk of restenosis in comparison to standard stents.
