Abstract

A rubber tip disconnection of Arrow-Trerotola percutaneous thrombolytic device (PTD) may occur occasionally. We experienced 5 cases of a rubber tip disconnection among 453 mechanical thrombectomy sessions with the use of PTD. We present a report about these five cases and suggest possible causes for the occurrences.

  Fig. 1 49-year-old man with thrombosed radio-cephalic native arteriovenous fistula. A. Angiography after mechanical thrombectomy using Arrow-Trerotola percutaneous thrombolytic device shows multiple residual thrombi (arrowheads) within cephalic vein. B. Mechanical thrombectomy was repeated. Because of acute angle at anastomosis site, soft rubber tip was curved (arrowhead). C. While device was working, soft rubber tip (arrowhead) was disconnected from catheter. D. Soft rubber tip was retrieved by using snare wire (arrowhead).
