Aneurysm Repair

The endovascular treatment of abdominal aortic aneurysm (EVAR) consists of inserting a delivery system through intravascular pathway and deploying one or several stent-grafts at the aneurysm site in order to exclude it. This procedure has proven to have a high success rate for eligible patient population and benefits in terms of reduced blood loss, intraoperative morbidity and length of hospital stay. As the selection criteria for EVAR extend progressively due to enhancements in the devices and delivery systems, clinicians are confronted with cases becoming increasingly difficult and demanding procedures with steep learning curve (aortic dissection, branched and fenestrated stent-graft, and complex anatomy with high tortuosity or short aortic neck). In this context patient-specific Finite Element Modeling (FEM) could provide a predictive tool to support endovascular device assessment and selection as well as intervention planning. Given the lack of dedicated solutions, the aim of this study was to assess the feasibility of simulating the main steps of EVAR procedure, from guidewire insertion to stent-graft deployment.

Objective By using a guidewire fixator, the distal guidewire position can be secured in an artery. This new principle enables a method for fenestrated endovascular aortic repair where the connection between the aortic branches and the stent graft fenestrations is made before inserting and deploying the stent graft. Methods This is conducted using a fenestrated stent graft with preloaded catheters, through which the prepositioned and distally secured guidewires from the branches are inserted. Results This report covers the method when implementing a single fenestration stent graft in pig. Conclusions Successful tests with single and dual fenestrated grafts have been conducted in pigs.

Endoleaks are the most common complications following endovascular aneurysm repair. Depending upon their origin, there are five types of endoleaks, types I-V, which can also be classified as direct and indirect endoleaks. Direct endoleaks type 1 and III have higher risk of aneurysm rupture due to rapid sac expansion, and require immediate correction.  Indirect endoleaks types II, IV and V have a relatively benign course compared to direct endoleaks. Most of them resolve with time and very few of them need interventions upon sac enlargement. Type V endotension is a special situation where there is sac enlargement despite no demonstrable endoleak. Proper planning and appropriate selection of stent-graft can prevent most of these endoleaks. With improvement in stent-graft technology, the incidence of endoleaks has been reduced. The current narrative review was planned to describe the pathophysiology, risk factors and treatment options for each type of endoleak. Continuous...
