[en] Purpose: To evaluate the efficacy of a new rotational thrombectomy device, and the procedure-related risk of particle embolization.Methods: The experiments were performed in transparent silicone tubes. The conditions of flow were as close as possible to physiological parameters. Distal embolization was detected by a mesh of nylon filters.Results: The Straub Rotarex catheter was able to remove all clots. The mean number of migrating particles larger than 1000 μm was 0.17 (± 0.38), the mean number of 400-1000 μm migrating particles was 1.08 (± 1.04). The mean intervention time was 67 (± 37) sec. The mean volume of collected liquid was 96.6 (± 24.7) ml.Conclusion: The in vitro results suggest that the Straub Rotarex catheter is able to remove large volumes of thrombus with a limited risk of embolization. The main limitation of our model is the absence of adhesion of the clot to the tube
[en] A port-catheter system was implanted via femoral artery access for hepatic artery chemotherapy infusion. Implantation was attempted in 90 patients and was successful in 88. Blood flow redistribution was performed using embolization coils. In the first ten patients a soft heparin-coated infusion catheter was used. For the following 78 patients we used a stiffer catheter coated with fluorine-acryl-styrene-urethane-silicone (FASUS) copolymer. The catheter was connected to a port implanted subcutaneously below the level of the inguinal ligament. Complications during the procedure and after placement were observed in 7 of 90 patients and 24 of 88 patients, respectively. These included catheter obstruction (11%), dislocation of the catheter tip (10%), drug toxicity (5.7%), and catheter infection (3.4%). In 6 of 10 patients with catheter obstruction, recanalization of the port system was achieved. In 7 of 9 patients with dislocation of the indwelling catheter tip, replacement of the port system was successful. Our complications appear to be comparable with those encountered with the subclavian/brachial approach when the new catheter coating is used. Notable is the avoidance of cerebral infarcts
[en] The 2013 ISI journal rankings are out and it is my pleasure to inform our readership that CVIR ranks 43/120 (2012: 46/118) journals in the field of radiology. The 2013 impact factor further improved to 2.138 (2012: 2.093). This means that Cardiovascular and Interventional Radiology again continues to be the highest ranked journal dedicated to the field of interventional radiology in 2013.This is mainly due to the great support we achieve by you as authors and readers of CVIR, your dedication to the profession, and your loyalty both to the journal and to CIRSE. For all of this, we owe you our thanks and respect.
