What is a necessary step in the AAA repair process regarding the access points?

In the context of abdominal aortic aneurysm (AAA) repair, particularly in endovascular procedures, having access in both groins is essential for several reasons. The bilateral groin access allows for the placement of multiple catheters and devices needed to perform the intervention effectively.

During endovascular aneurysm repair (EVAR), access points in both groins are often utilized to facilitate the introduction of delivery systems for the stent grafts. This dual access not only provides more maneuverability but also enables the use of advanced techniques such as simultaneous use of contralateral and ipsilateral access, which can be crucial in cases requiring complex maneuvers to navigate arterial anatomy.

Moreover, having access in both groins can be a significant advantage in managing potential complications. If one access point encounters issues, such as bleeding or difficulty in advancing devices, the other access point can serve as a backup, ensuring that the procedure can continue with minimal interruption.

In summary, the necessity of access in both groins during AAA repairs is primarily rooted in ensuring adequate access for the devices, enhancing procedural flexibility, and providing safety during the intervention.
