摘要
Objectives: To determine the utility of percutaneous transluminal angioplasty (PTA) of the femoropopliteal segment in patients with claudication and critical leg ischaemia (CLI). Design: Longitudinal observational study. Setting: A university based vascular surgical centre. Material: Ninety-five patients with stenosing or occlusive arterial lesions of the femoropopliteal segment underwent 52 primary PTA for claudication and 50 primary PTA for CLI. Methods: The procedure was considered haemodynamically successful when the increase of immediate postprocedural ABI was 0.15 or more. The criterion for haemodynamic success during follow-up was an ABI having not decreased by more than 0.15 from the immediate postprocedural level. The run-off arteries were graded according to the scoring system proposed by the SVS/ISCVS. Results: Among the technically successful procedures (83%), the haemodynamic success rate was 77% at 1 month,, 55% after 1 year, and 51% after 2 years. The cumulative haemodynamic success rates were 83%, 66% and 61% in claudicants, and 70%, 42%, and 38% in CLI (p = 0.03). In patients with a run-off score less than or equal to 7.5, the success rates were 84%, 67%, and 60%, respectively, whereas in those with a crural score >7.5 these were 61%, 39%, and 39%, respectively (p = 0.04). Conclusions: The haemodynamic results suggest that PTA to the femoropopliteal segment is seldom a procedure of choice for critically ischaemic legs with poor run-off. The run-off score is useful in identifying patients who may benefit from PTA.
