PURPOSE: To evaluate the feasibility of use of the Arrow-Trerotola percutan
eous thrombolytic device (PTD) in the treatment of thrombosed hemodialysis
native fistula occlusions,
MATERIALS AND METHODS: Ten patients with native fistula occlusion underwent
mechanical thrombolysis with use of the PTD. The standard PTD was used in
seven patients and the over-the-wire device was used in three patients, Maj
or outcomes of our study included procedure time, clinical success, complic
ation rate, and 3- and 6-month patency rates,
RESULTS: The technical success rate was 100% and the clinical success rate
was 90% (9 of 10), In all 10 cases, the procedure was associated with angio
plasty, There were no major complications. The mean time of successful proc
edures was 126.1 minutes. The 3- and 6-month primary patency rates were 70%
and 60%, respectively; the assisted primary patency rate at 6 months was 8
0%,
CONCLUSION: The PTD is an effective mechanical device for percutaneous trea
tment of thrombosed hemodialysis access. Our clinically successful initial
experience with the PTD shows that the technique is rapid and safe for trea
tment of native fistula occlusions.
