Endovascular treatment of profunda femoris artery obstructive disease: nonsense or useful tool in selected cases?

BACKGROUND

To evaluate the therapeutic value of endovascular techniques for the treatment of profunda femoris artery obstructive disease (PFAOD) in critical limb ischaemia (CLI) patients, with technically demanding open profunda repair.

DESIGN

Retrospective study of prospectively collected data of 15 consecutive CLI patients with technically demanding surgical treatment of PFAOD, that were treated by endovascular means in two European Centers of Vascular Surgery.

MATERIALS

All patients had critical limb ischaemia with a history of at least two previous vascular reconstructions in the ipsilateral groin and severe co-morbid conditions. All patients had good common femoral artery flow, long occlusion of the superficial femoral and popliteal arteries and impairment of crural arteries.

METHODS

Twelve patients underwent balloon angioplasty alone and, in the other three cases, an additional stent placement was necessary, due to flow-limiting dissection. The follow-up (mean 29.2+/-10 months) included a surveillance protocol with the best medical treatment and duplex scanning at 1, 3, 6, 12 months and yearly thereafter.

RESULTS

The endovascular approach was technically successful in all cases and the procedure-related morbidity and mortality rates were 0% for the entire follow-up period. The 3-year primary and secondary patency rates of the treated segment were 80% and 86.7%, respectively. The limb salvage rate was 93.3%.

CONCLUSIONS

The outcome of our series underscores the therapeutic value of balloon angioplasty in cases of severe PFAOD, as bailout treatment in critical limb ischaemia patients with technically demanding open profunda repair. This procedure can be repeated easily if significant restenosis occurs and provides a useful tool in selected cases.
