Theodosios Bisdas commented on presentation Removing stent grafts and implications for putting them in.

»Thank you Dr. Park for this nice presentation. The message is clear and I found the paradigm about pacemakers and the results of the EVAR-1 trial very pertinent and successful. However, as you mention in your presentation, the majority of the stent-grafts that you have already explanted are more or less stent-grafts of the previous generations. Do you not believe that the next generation of endografts (similarly to the next generation of pacemakers) have a much higher safety profile? Finally, I would like to invite you to upload any presentations or videos regarding technical tips for the surgical explantation of endografts after failed EVAR. That would be a great help for the daily practice of several vascular surgeons. Unfortunately, we are missing such kind of presentations in most congresses.«

Raphael Coscas replied to your comment on presentation Clampless Anastomosis on the Supraceliac Aorta for Aorto-mesenteric Bypass.

»Thank you for your comment, This is not our standard technique since it leave a stent across the anastomosis and some uncertainties remain about the durability. However, we performed our first case 3 years ago (on the infrarenal aorta) and the patient is still doing well with a patent stent and bypass.«

Theodosios Bisdas commented on presentation Clampless Anastomosis on the Supraceliac Aorta for Aorto-mesenteric Bypass.

»Great contribution Raphael. Did I understand your technique right? Are you puncturing the graft twice or only at the distal part? How are you puncturing the aortic wall in order to introduce your wire? My second question: can you provide us the diameters of the graft and the BeGraft? Do you perform any predilatation of the aorta at the level of the anastomosis?«
Technical note

Removing stent grafts and implications for putting them in

“Who will do my aortic surgery when my time comes” was a common refrain among my mentors, only half jokingly. Now, the question has gained a sharpness. I think the tide will turn and the kids will do fine, but we all have to do a bit of reclamation, or open surgery will become the habit of strange eccentric artisans. I recommend calling up the retired surgeon and inviting them in for conferences and cases. Reprint masterwork atlases like Wiley’s. Connect with likeminded. Before it’s too late.

W. Michael Park commented on presentation Management of the false lumen in chronic aortic dissection.

»Nice presentation. There is a brief moment of terror as you push the syringe on the balloon and you meet resistance then bing -it's out. You peek over at the A-line trace, smile. You then drop the balloon like you're sneaking out of a party with the host's silverware. On a serious note, without sealing retrograde false lumen flow, the hemodynamics take on that of a long track pseudo aneurysm and the arch hump will grow. Sometimes an appropriately sized stent graft will bust out of the constraints of the true lumen, but from experience, the chronic flap can be as tough as adventitia.«
