Hi everybody!!! I am a vascular surgeon since 2002. Currently, I am working in Attikon Teaching Hospital in Athens, Greece. I like endovascular surgery but even more I like performing open procedures mainly distal and ultra-distal peripheral bypasses to the arteries of the calf and foot. I am also interested in complex open aortic surgery, with a special preference in pararenal, suprarenal and thoracoabdominal aortic aneurysms. I am also interested in the repair of short and long-term complications of aortic surgery, including aortic graft infections and para-anastomotic aneurysms. I also like open carotid surgery with a special interest in acute and hyper-acute surgery post stroke. Finally, I like treating patients with thoracic outlet syndrome with first rib resection. I am the proud father of Michael and Rea and the happy husband of Maria. It is really good to be here!!

Gladiol Zenunaj commented on presentation VRTD 2: Association between PTX-coated devices and overall mortality.

»Greetings, thanks for sharing your research. The authors are reporting that mortality paclitaxel- related is dependent on the dose loaded on the device. Do the authors think that mortality paclitaxel-related after 1 year could depend whether on the paclitaxel load transferred to vessel wall or the load lost in the bloodstream during the delivering of the device. If this could be related to the load of paclitaxel lost during the delivering it shuld urge the developement of better drug bonding to the device.«

»Very interesting paper. However, if their findings are confirmed in other studies, I think it might have any impact on the PTX-devices use rather than reducing the number of endovascular procedures. Nowadays, the increasing age, number of comorbidities of patients we have to deal with, make an open approach unthinkable.«

»RCTs were included only in the meta-analysis. The paclitaxel arms and the control arms had similar-comparable baseline demographics without any significant differences (please refer to Appendix of the paper in JAHA). Not all studies had the same periods of follow-up time. Hence, the different number of studies for each time point. Our raw data is available 'open access' in the paper for any body to double-check. Independent reviews are of course more than welcome.«

Giovanni Torsello commented on presentation VRTD 2: Association between PTX-coated devices and overall mortality.

»I am not a statistician. But the statement "the two group are identical" is wrong. The groups may be comparable. Randomization was for sure not done for life expectancy, but for lesion characteristics. We need the opinion of a statistician. The study was not accepted for publication in "high ranked" Journals. Why? Additionally, the comparison of many studies at the beginning and of a few studies at 2 and 5 years looks "strange" in my opinion. The studies were externally controlled by Independent committees. What is the reason why they did not find safety issues? It is a pity that these points were not addressed during the round table.«
