How many angioplasties for peripheral arterial disease were done in
the US in the past 5 years? Of those, how many included the placing of
a stent during the angioplasty?
Data on only one of these years would also
be of value.

More than 37,000 peripheral arterial angioplasties were performed on
Medicare beneficiaries in 1996 (50% for lower extremity, 33% iliac,
and 17% renal arterial disease). Cardiologists performed 26% of these
procedures overall, including 37% of the renal angioplasties. Few
(12%) procedures were done as part of a cardiac catheterization;
instead, most were done as a separate procedure. Use of peripheral
angioplasty varied more than 14-fold across HRRs (median, 12
procedures per 10,000 beneficiaries; 10th to 90th percentile, 4.1 to
57.9). The mean angioplasty rate in HRRs where cardiologists performed
50% or more of the procedures was almost double that of regions where
they performed none (21.9 vs. 12.1 procedures per 10,000
beneficiaries; P < 0.001).
