Background. The endovascular salvage of occluded autogenous radial-cephalic fistulae is a more challenging procedure than that for stenotic fistulae. To obtain an access to the fistula is one of the keys to success. Both retrograde venous approach and brachial artery approach have some disadvantages. The radial artery approach has been used in the endovascular therapy of fistula dysfunction, but few data focused on their feasibility and safety for the totally occluded fistulae. Methods. We retrospectively reviewed the patients with occluded autogenous radial-cephalic fistulae receiving endovascular salvage via the radial artery approach in our institution. From January 2004 to July 2007, 48 patients fulfilling the above criteria were enrolled. Balloon maceration was used for patients with small clots. Mechanical thrombectomy with an Arrow-Trerotola percutaneous thrombolytic device or an AngioJet rheolytic catheter was used for patients with large clot burden. Outcome variables included anatomic and clinical success, complications and primary and secondary patency. Results. All the transradial punctures were successful. Anatomic and clinical success was achieved in 96% of the cases. The post-interventional primary patency rates were 92%, 77%, 55% and 44% at 1, 3, 6 and 12 months, respectively. The post-interventional secondary patency rates were 96%, 93%, 89% and 89% at 1, 3, 6 and 12 months, respectively. The 12-month primary patency of the short-segment thrombus group was better than that of the long-segment thrombus group (57% versus 19%, P = 0.005). The complication rate was 4%. No puncture-site-related complications were noted, and all the radial arteries were palpable at follow-up. Conclusions. An endovascular intervention through the radial artery approach is a safe and feasible strategy choice for restoring occluded autogenous radial-cephalic fistulae.

AngioJet Thrombectomy to Salvage Thrombosed Native Dialysis Fistulas

Zhōnghuá mínguó xīnzàngxué huì zázhì (2011)

Purpose: To investigate outcomes following treatment of thrombosed native dialysis fistulas with AngioJet thrombectomy. Materials and Methods: We retrospectively reviewed an existing database and included patients according to the following criteria: thrombosed fistula, native fistula, and use of the AngioJet system for mechanical thrombectomy. Outcomes included clinical success, complications, and patency rates. Results: One hundred and nine patients with 135 episodes of native fistula thrombosis were included in the study. Clinical success was achieved in 76% (103 of 135) of the procedures. Fistulas salvaged within three days of thrombosis had higher clinical success rates than those salvaged after three days (80% vs. 63%). The average procedure time was 82 37 minutes. Complications occurred in 15% (20 of 135) of the procedures, but all were not device-related. The primary patency rates were 67%, 57%, and 39% and the secondary patency rates were 74%, 72%, and 70% at 30, 90, and 180 days, respectively. In the Cox regression analysis, only diabetes mellitus, current smoker, right-sided fistula and small vessel size were independent predictors of primary patency. Conclusion: Percutaneous thrombectomy using the AngioJet system is effective for the salvage of thrombosed native dialysis fistulas. It has an acceptable complication rate, primary patency rate, and secondary patency rate.
