OBJECTIVES: To define the role of bypass surgery and percutaneous transluminal angioplasty to manage critical limb ischaemia due to infrainguinal @entity432 . DESIGN: Retrospective review. SETTING: Regional hospital, Hong Kong. @entity1 : Consecutive @entity1 treated for critical limb ischaemia, for whom data were prospectively collected in those who underwent: (i) infrainguinal percutaneous transluminal angioplasty first, or (ii) infrainguinal bypass surgery. RESULTS: Among @entity1 with @entity6250 , 364 consecutive individuals having infrainguinal bypass operations and 100 having percutaneous transluminal angioplasty first were compared. The latter @entity1 were older (77 vs 74 years, P=0.014) and had more co-morbidities but higher ankle pressure than those having bypass surgery. In the angioplasty-first group, 74% had favourable lesions (classified as TransAtlantic Inter-Society Consensus A/B). In the bypass group, operative mortality was higher (4% vs 1%, P=0.03) than that in the angioplasty-first group. Hospital mortality was comparable (8% vs 3%, P=0.15). In the bypass group, median hospital stay was longer than that in the angioplasty-first group (24 vs 4 days, P<0.001), and postoperatively they also had a higher median ankle-brachial index (0.92 vs 0.70, P<0.001) and superior long-term patency. In the bypass group, American Society of Anesthesiologists class 4 @entity1 suffered very high operative and hospital mortality (15% and 31%, respectively). Long-term patency of percutaneous transluminal angioplasty depended on the TransAtlantic Inter-Society Consensus class of the treated lesion. Limb salvage rates at 3 years were 89% and 78% for percutaneous transluminal angioplasty first and surgical bypass, respectively (P=0.046). Long-term survival was poorer in the percutaneous transluminal angioplasty-first group (21% vs 51% at 5 years, P=0.04). CONCLUSION: Infrainguinal bypass and percutaneous transluminal angioplasty are complementary. For TransAtlantic Inter-Society Consensus A and B lesions, percutaneous transluminal angioplasty should be offered first. For American Society of Anesthesiologists class 4 @entity1 , percutaneous transluminal angioplasty should be considered first, regardless of the TransAtlantic Inter-Society Consensus class.
