Dr. Bisdas (Vascular Surgeon, Muenster, Germany) performs a chimney endografting for a penetrating and symptomatic aortic ulcer. In this live case, you will see the most important steps for a successful chEVAR. Moreover, the experts discuss extensively important technical issues and potential challenges during the procedure.
"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.
Since India’s Sushruta (800-600 BC) first reported that "aneurysms can be cured only with the greatest difficulty", the majority of surgeons shared a fear of aortic surgery till the first half of the 20th century. The surgical treatment of AAA became available only in the second half of the 20th century. This presentation summarizes the most important historical milestones in AAA surgery.
Giovanni Torsello (Vascular Surgeon, GER) presents and discusses with the experts the latest results from an experimental head-to-head investigation of different bridging stent-grafts (BSG) used in fenestrated aortic endografting.
How does the material respond to balloon dilatation? Which are the forces that might lead to the dislocation of the BSG from a fenestration? Endoleak of unknown origin after fEVAR: could be associated with material fatigue?
Despite the latest advances in both endovascular field and open repair, a ruptured AAA still remains one of the most challenging situations in vascular medicine. This case shows the use of chimney and periscope grafts for the treatment of a Type Ia Endoleak in patient presenting with a ruptured AAA.
In this video case, we present our standard practice of open surgical repair for pararenal AAA. In general, we performed open repair with the “clamp and sew” technique, and the application of cold renal perfusion is limited to the cases with renal revascularization. Sometimes, division of left renal vein is imperative for better access to the suprarenal aorta. Retrospective analysis of our series revealed no negative impact of the division on long-term renal function - J Vasc Surg 2018;67:1042-1
This is a case report describing the different steps of the implantation of a fenestrated preloaded endograft to treat a juxtarenal aneurysm with calcified and tortuous iliacs.
This presentation summarizes the results of the first topic of the polling station about asymptomatic juxta- and suprarenal aortic aneurysms.
Total number of votes: 103.
The results are now open for discussion.
One of the main topics at each meeting is the discussion about the importance and clinical relevance of gutter-related endoleaks after ch-EVAR. Herein, we present you an overview of the most important causative mechanisms for the development of persistent gutters and tips to treat and minimize the risk of appearance.
This is a case of a thoracoabdominal aortic aneurysm treated by a low-profile branched endograft. In this video, you will find our algorithm for staging the aortic procedures, to reduce the risk of spinal cord ischemia, the steps of the procedure, important tips and tricks for a successful outcome and finally, the impact of the totally percutaneous approach for the quick recovery of the patient.
This presentation is a snapshot of the main characteristics of the t-branch endograft for the treatment of thoracoabdominal aortic aneurysms (TAAA). Moreover, we present our institution's algorithm regarding the steps of the procedure and the OP setting in order to achieve the best outcome for the patient and to prevent spinal cord ischemia.
In this case, a type Ia endoleak after migration of a Talent endograft was treated successfully by chimney endografting. This case shows all steps of the procedure and describes the required materials (catheters, balloon catheters, bridging stent-grafts etc). The big challenges, in this case, were the angulated neck, the renal artery stenoses and the stent struts at the origin of the renal arteries.
This case demonstrates the percutaneous transluminal thrombectomy of a bridging stent-graft after chEVAR. The clot removal was performed with the Indigo thrombectomy catheter (Penumbra) through a transaxillary approach. In this video, you will find important technical aspects as well as all relevant characteristics of the device.
In this presentation, you will find important information about the chimney technique (chEVAR) for the treatment of juxtarenal or pararenal aortic aneurysms.
