We undertook a prospective evaluation to prove a new mechanical thrombectom
y device, the shredding embolectomy thrombectomy catheter (S.E.T, catheter)
, for the treatment of patients with acute lower-limb ischemia. The study e
valuated the success, patency, mortality, limb salvage, and complication ra
tes for 51 patients treated from January 1994 through June 1996, with this
device, which was an 8-F three-lumen catheter. The onset of symptoms was 8.
6 +/- 9 days. Thrombus length was 18 +/- 9 cm situated in 44 native vessels
and in 7 bypasses, 42 limbs were graded as threatened. Hydromechanical thr
ombectomy with the S.E.T. catheter proved to be a quick and safe adjunct fo
r therapy of acute femoropopliteal thromboembolic occlusions with a high in
itial success rate and an acceptable mid-term patency rate.
