Five-year retrograde transpopliteal angioplasty results compared with antegrade angioplasty

Abstract

Introduction: Retrograde transpopliteal angioplasty (PA) is a potentially useful alternative technique for endovascular treatment of infra-inguinal arterial disease when antegrade transfemoral puncture (FA) is technically not possible or appropriate. This study aimed to investigate the outcomes of PA compared with FA during a 5-year period.

Patients and methods: A retrospective study was performed to assess 88 PA and 275 FA performed between January 2003 and January 2008. Assessments of patients, indication for procedure, disease site, stenosis severity, procedure outcomes and time to further intervention were recorded.

Results: FA was used to treat more patients with critical ischaemia (42.2% vs 30.7%; P = 0.014)). PA was used to treat more proximal superficial femoral lesions (P < 0.001) and occlusive lesions (P = 0.001). Overall, 84.1% of PA and 82.5 % of FA were technically successful. There was no difference in local puncture site complication rates. Significantly more FA resulted in distal thrombus/embolism (8.4% vs 3.4%; P = 0.044). Further intervention was required in 27.3% of PA and 36.0% of FA. The time interval to re-intervention was not different between the groups.

Conclusions: PA is safe with comparable success rates and long-term outcomes to an FA. PA is a useful alternative approach for treating occlusive, proximal disease.
