Thromboembolectomy with a Fogarty catheter. Our clinical experience

BACKGROUND: The Fogarty thromboembolectomy (TE) has been considered for a long time the best treatment for acute peripheral arterial occlusion. However, recently new therapeutic options like thrombolytic agents (local or systemic) have been introduced. METHODS: A total of 66 patients who underwent Fogarty TE for acute thromboembolic limb ischemia has been retrospectively studied. Patients with documented atherosclerotic pathology who were treated with other revascularization procedures were excluded. Patients were divided into four groups: 1) upper limb embolism, 2) lower limb embolism, 3) thrombosis on atherosclerotic plaque or on a graft, 4) post-traumatic thrombosis. Twelve patients underwent Fogarty TE for upper limb thromboembolic ischemia and 54 for lower limb; 57.5% of patients had atrial fibrillation. RESULTS: Procedures were successful in 59 patients (89.4%). Further surgical procedures (bypass, arterioplasty, further embolectomy) were performed in 35.1% (19/54) of patients of groups 2 and 3 with acute lower limb ischemia. Results were very good in group 1 and 4. Seven of the 54 patients treated for lower limb ischemia underwent limb amputation (12.9%), while hospital mortality was similar for lower and upper limb (31.4 and 33.3% respectively). CONCLUSIONS: The Fogarty TE is still a good option to revascularize acute ischemic peripheral arteries with good results in a high number of patients and should be particularly used where it is possible to perform additional techniques in case of failure.
