Key result
Percutaneous transluminal recanalization achieves marked improvement in ~55% of extremities, averting four amputations.
Why the study?
A new procedure for transluminal recanalization of arteriosclerotic obstructions was developed to improve treatment outcomes for femoral and popliteal artery lesions.
Does percutaneous transluminal recanalization improve outcomes and avert amputation in patients with arteriosclerotic obstructions of the femoral and popliteal arteries?

Does percutaneous transluminal recanalization improve outcomes and avert amputation in patients with arteriosclerotic obstructions of the femoral and popliteal arteries?
This early report demonstrates the feasibility and potential limb-salvage benefits of percutaneous transluminal recanalization for arteriosclerotic obstructions.
May support limb salvage via percutaneous recanalization in select cases; leaves open efficacy and safety in prospective trials.
The rationale and technic of a new procedure—transluminal recanalization of arterio-sclerotic obstructions—has been described. Of the 11 extremities treated, six have shown marked improvement (four amputations averted). It is reasonable to assume that with a perfected technic and patients with less advanced disease, the percentage of successful recanalizations would increase. Early treatment with this technic may well prevent otherwise serious disease, not just prevent amputation of extremities not suitable for definitive surgery. We are satisfied that percutaneous transluminal recanalization is the treatment of choice for many lesions of the femoral and popliteal arteries. We believe this method is ready for application to obstructions up to approximately 10 cm. by those skilled in the use of vascular catheters. No doubt the interest and ingenuity of others will lead to refinements of technic as well as further clarification of the role of this attack on arteriosclerotic obstructions.

Dotter et al. (1964) conducted a case report in Arteriosclerotic obstruction (n=11). Percutaneous transluminal recanalization was evaluated on Marked improvement. Percutaneous transluminal recanalization of arteriosclerotic obstructions resulted in marked improvement in 54.5% (6 of 11) of treated extremities, averting four amputations.
