Percutaneous angioplasty of the profunda femoris artery: a safe and effective endovascular technique.
The limb with an occluded superficial femoral artery (SFA) relies on the profunda collaterals for adequate perfusion. Frequently the profunda is also diseased exacerbating the limb ischaemia. We have used percutaneous transluminal angioplasty (PTA) of the profunda increasingly in recent years to treat such patients. In 28 limbs there was one technical failure, no major complications and six minor wound haematomas. A combination of SFA and profunda PTA was used in 11 patients. Ten of these became asymptomatic and one improved. In 16 patients a long SFA occlusion was unsuitable for PTA. An iliac and profunda PTA was performed in six of these, with resolution of (three) or significant improvement in (three) symptoms. Profunda PTA alone was used in the remaining 10 patients who constituted a high risk elderly group all with limb threatening or disabling ischaemia. Symptomatic improvement in seven of these enabled surgery to be avoided. A bypass procedure was performed in the three patients who failed to improve. Poor run-off (< one healthy calf vessel) was the major factor limiting the effectiveness of profunda PTA in these patients. Profunda PTA is a safe and effective procedure of particular value in high risk patients with a long SFA occlusion and at least one healthy calf vessel run-off.
