Hemodynamic and mechanical interpretation of the clinical performance of abdominal aortic endografts: principles and considerations

What are the factors predisposing to migration of endografts after EVAR? How are the stresses, pressure and forces distributed postiperatively? Can the geometric parameters predict future adverse effects? How are mechanical, hemodynamic and geometrical changes interconnected postinterventionally? This presentation introduces some basic hemodynamic pronciples and terminology as a means to comprehend the phenomena taking place after endograft implantation.

Endovascular treatment of bilateral hypogastric artery aneurysms

This is a recorded case of bilateral hypogastric artery aneurysm treated by coil embolization on the one side and an iliac-side branch device on the other side. In this video, you will learn about access vessels, decision making, how to embolize the aneurysm of the hypogastric artery, how to implant the iliac-side branch device as well as further relevant technical aspects and features of the device.

TAAA: Back table surgeon-modified stent-graft with internal branches

We report some cases performed with a stent-graft modified by the surgeon with internal branches for the treatment of TAAAs. In total, we have 34 cases performed with this technique and we developed and patented a low profile device to be used in almost all anatomical types of TAAAs. This device may be considered off-the-shelf graft. See also: https://vascupedia.com/presentation/an-off-the-shelf-and-low-profile-stentgraft-for-treatment-of-thoracoabdominal-aneurysms/

Total endovascular treatment of the aortic arch after type A dissection with chimney and sandwich technique

This is a very advanced case of a total endovascular repair of a post-type A dissection aneurysm of the aortic arch with chimney endografts for the brachiocephalic trunk and the LCCA and a periscope in Sandwich technique for the LSA. See the procedure in chapters for the different steps under: https://vascupedia.com/video/total-endovascular-treatment-of-the-aortic-arch-after-type-a-dissection-with-chimney-and-sandwich-technique/

An off the shelf and low profile stentgraft for treatment of thoracoabdominal aneurysms

I recently developed an off the shelf stentgraft for treatment of thoracoabdominal aortic aneurysms involving the visceral branches. With this off the shelf device, aneurysms can be treated with any anatomical configuration of the visceral vessels, such as only 1, 2, 3 or 4 branches. I began to have the idea of developing this device from a technique of internal branches that I developed for treatments of thoracoabdominal aneurysms. We performed almost 40 patients with this technique.

Two technical tips for severely angulated infrarenal necks during EVAR

This is a short video with two technical tips for the treatment of severely angulated necks with standard EVAR (Endurant, Medtronic) if an open surgical repair is not indicated. The first tip starts with the release of the top cap before the opening of the contralateral gate and the second tip is a solution to pull safely back the top cap if you have a conflict with the suprarenal stent. However, do not forget that this is an outside the IFU implantation of the device.

Onyx embolisation of a type 2 endoleak after EVAR

This is a recorded case presenting all important steps of type 2 endoleak embolization with Onyx (Medtronic). The source of the endoleak was the inferior mesenteric artery, which was reached as usually from the SMA to the middle colic artery (mostly on the right side of the SMA in AP projection) and the Riolan anastomosis.

Iliac-side branch devices: What does the data teach us?

This is an overview of the literature about the revascularization of the hypogastric artery (HA) in patients with aortoiliac aortic aneurysms. Should we preserve the HA? If yes, how? If not, which is the best method to avoid complications? Which are the current IBD devices?

Zenith t-branch for the treatment of TAAAs: planning and algorithm

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.

Treatment of a type Ia endoleak with chEVAR: steps and materials

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.

Percutaneous thrombectomy of bridging stent-grafts after chEVAR

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.
