Renal artery stent placement slows progression of
renovascular hypertension
16th Scientific Meeting of the International Society of Hypertension
ISH Abstract Book
(Jun) 16: 1996
14 patients with renovascular disease had a Palmatz stent inserted.
The rate of loss of renal function - determined from the slope of
serum creatinine against time was less in the 11 post stent insertion
than in the 17 months before.
Comment: Don't rush out and put stents in all your
patients with renovascular disease. The literature is littered with
uncontrolled trials in renovascular disease and this is another! The
main flaw is that stents are inserted to preserve renal function and
the stimulus to intervene is usually a more rapid decline in function
(the slope will therefore be steep before intervention). The results
are interesting but a placebo controlled trial is needed (Alan
Jardine, M.D., Glasgow University, Scotland).
