Abstract | BACKGROUND:
Critical limb ischemia is an increasingly common condition that has high surgical morbidity and limited non-surgical options. OBJECTIVES: METHODS: Between January 2003 and March 2004, 41 stents were inserted into 17 consecutive patients (11 males, 6 females, mean age 82 years, range 75-93) following unsuccessful or complicated PTA. Seven patients had one-vessel run-off, six had two-vessel and four had three vessel run-off. All patients suffered from CLI, had up to three lesions and more than one co-morbid condition, and were considered at high surgical risk. Silicon carbide-coated Motion coronary stents, 2.5-4 mm diameterand 25 and 30 mm length, were used. Pre-intervention assessment included clinical condition, ankle brachial index, Doppler ultrasound and digital subtracted angiography. Postintervention evaluation included clinical condition, ABI and Doppler ultrasound at 3, 6 and 12 months. RESULTS: The technical success rate per lesion was 100% (41/41). Two patients died of unrelated causes after 2 and 8 months respectively. Primary patency rates with duplex ultrasound were 68.7% (11/16) at 3 months, 43.7% (7/16) at 6 months and 40% (6/15) after 12 months. Nine patients developed complete occlusion in 13 stents; three of these patients underwent a below-knee amputation and two patients a partial foot amputation. Re-intervention (PTA only) was performed in 7 patients (43.7%). Secondary patency rate was 81.2% (13/16) at 6 months and 60% (9/15) at one year. Mean ABI index had improved at 6 months from 0.32 to 0.67, and to 0.53 at one year. Clinical improvement was evident in 87.5% (14/16) at 6 months and in 66.6% (10/15) at one year. CONCLUSIONS:
