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.

Review of the literature

Diagnostic algorithms for endoleaks

This is a current overview of the evidence and techniques regarding the time and type of endoleak treatment as well as information about postoperative anticoagulation. Moreover, we provide our institution's algorithm about the surveillance protocol of endoleaks after EVAR procedures.

Principles of EVAR planning and sizing – Chapter 1: Drawing & Measurements

This short tutorial is the first chapter of an online workshop about the principles of EVAR planning. Herein, you will find all important steps for a successful preparation of your EVAR procedure. What about drawing? What should I draw? What are the anatomic issues need to be addressed and considered? and much more information.

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.

Review of the literature

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?
