Theodosios Bisdas replied to your comment on presentation Total endovascular treatment of the aortic arch after type A dissection with chimney and sandwich technique.

»Hi Michel! Thank you for your question. Regarding your first question. I did not use for example the Endurant limb because of the length (82mm) and the difference of the materials compared to the cTAG (Dacron vs PTFE). I think the gutter could be an issue. The IIA-branch of the IBD device is tapered (16 to 12mm) and shorter (70mm). Regarding your second question, the downwards orientated branch for the LSA allows access for a branched endograft and principally for a transbrachial approach.«

Theodosios Bisdas replied to your comment on presentation Total endovascular treatment of the aortic arch after type A dissection with chimney and sandwich technique.

»Thank you, Martin! Well, we are far away from a well-established protocol for CSI protection. Especially, in that case, you have to be very quick after deploying the thoracic endograft over the aortic arch. There are some new filters for the brachiocephalic trunk and the LCCA but these are applicable only in TEVAR cases. When you have to get access for the supraaortic vessels you have no option to protect the brain. My measures are: 1. Remove very carefully the air from the devices 2. Check multiple times your angiographic catheters to avoid air embolisation 3. Avoid a lot of manipulations with your thoracic endograft 4. Introduce the large-bore sheaths (12F), when you really need them and not from the beginning of the procedure 5. Check the quality of your arch at the angio-CT before planning your procedure.«

MARTIN MARESCH commented on presentation Total endovascular treatment of the aortic arch after type A dissection with chimney and sandwich technique.

»Amazing case Theo! Great tutorial from many points of view. Great discussion. Meticulous planning is the key to success in these cases! That's why they didn't use C-S bypass, Michael even so it would make sense, but this would have closed the door for further interventions distally if needed. Theo, can you comment on your CSI protective measures in complex TEVAR cases and what's the incidence of stroke and how to minimize it? Thanks«

Özgün Sensebat replied to your comment on presentation Total endovascular treatment of the aortic arch after type A dissection with chimney and sandwich technique.

»Thank you for your answer Theo! My question was not precise, sorry. It is obvious, that you've done a great case with this chimney/periscope exclusion and not with a CMD. I am sure the planning was complex. My question is your general opinion about CM-branched-devices for the arch if indicated. You answered my question why it was not possible in this particular case. Maybe it is possible in the future to see a CMD-case for the arch at Vascupedia. Your opinion about the indication and characteristics would be valuable for the vascular public. Again, great job!«

Theodosios Bisdas replied to your comment on presentation Total endovascular treatment of the aortic arch after type A dissection with chimney and sandwich technique.

»Thank you Arne for your questions. 1. We decided against a 3 chimney for 2 reasons: (a) to avoid a bigger gutter and (b) to have the option for an antegrade (transbrachial) access to the descending aorta (e.g. further endovascular repair with fenestrated or branched endograft) 2. See my comment to Dr. Sensebat 3. The patient will receive dual antiplatelet treatment for 3 months and afterwards only ASA. However, I cannot support this with any kind of evidence. The advantage is that we have large bridging stent-grafts (12 mm for the brachiocephalic trunk and 10mm for LCCA and LSA).«

Theodosios Bisdas replied to your comment on presentation Total endovascular treatment of the aortic arch after type A dissection with chimney and sandwich technique.

»Thank you Özgün for your question. This was not a custom-made device, but an off-the-shelf treatment with chimney and sandwich technique. A custom-made device was not indicated in that case due to the short length of the replaced ascending aorta. There are strict inclusion and exclusion criteria for those cases. We decided to go forward with an endovascular approach due to the comorbidity of the patient and the redo operation.«

VASCUPEDIA@LINC – ENDOLEAKS-CASE-BASED SOLUTIONS

The topic of this month is called ENDOLEAKS-CASE-BASED SOLUTIONS and aims to provide more information to the discussants of the session about endoleaks that will take place on Thursday, January 30, 2020 in Leipzig, during the LINC symposium. Take the opportunity to answer the questions and to inform the experts about your current practice for the treatment of all type of endoleaks.

Your participation will provide unique data for an interesting discussion and your answers will challenge the experts during the session.

The radiation exposure

Since January 2018, employers in the U.K and Europe have had to comply with their duties under the Ionising Radiations Regulations 2017, IRR17. Previous to this most health trusts working with ionising radiation followed IRR99.

The main changes since the last edition (IRR99) that affect the operator:

  • The dose limit for exposure to the lens of the eye has been reduced from 150 mSv to 20 mSv in a year. This is usually assessed using forehead monitoring bands.

It is the duty of the operator to control methods for restricting exposure to ionising radiation by use of distance and shielding etc.
