    Abstract:
    BACKGROUND: Subintimal angioplasty may be more successful than conventional (intraluminal) angioplasty for treatment of long femoropopliteal occlusions. This study assessed the clinical and haemodynamic outcome of subintimal angioplasty. METHODS: All patients with femoropopliteal occlusions treated by subintimal angioplasty over a 3-year period at two centres were reviewed. Clinical assessment and colour duplex imaging were carried out. RESULTS: Sixty-nine procedures were performed in 33 men and 33 women of median age 74 (range 47-92) years. Indications for treatment were intermittent claudication in 26 (38 per cent) and critical limb ischaemia in 43 (62 per cent). Median occlusion length was 10 (range 2-50) cm. Primary technical success was achieved in 51 occlusions (74 per cent). There were 11 complications (16 per cent); the majority were minor but surgical intervention was required in two patients (3 per cent). At 6 months the cumulative symptomatic and haemodynamic primary patency rates were 60 and 51 per cent respectively, analysed on an intention-to-treat basis. The symptomatic and haemodynamic patency rates for technically successful procedures were 80 and 77 per cent respectively. CONCLUSION: In this series the short-term clinical success of subintimal angioplasty was poor because of a high incidence of reocclusion and restenosis, despite a relatively high initial technical success rate.
