Clinical Challenges in Vascular Surgery: The Risk & Reality of EVAR Complications

It’s 2 a.m. The on-call resident’s voice is shaky.
The CT shows an 18cm abdominal aortic aneurysm with a Type 1B endoleak.
There’s gas in the sac, fluid in the belly, and the patient has a defibrillator on both sides of his chest.
Is it a rupture? A graft infection? An aortoenteric fistula? All of the above?
You’re the vascular surgeon, what do you do?

This episode dives deep into decision-making when EVAR fails, when infection strikes, and when the patient might not survive a definitive repair. Let’s talk about what happens when clinical textbooks meet real-world chaos.

Hosts:
· Christian Hadeed -PGY 4 General Surgery, Brookdale Hospital Medical Center
· Paul Haser -Division chief, Vascular Surgery, Brookdale Hospital Medical Center
· Andrew Harrington, Vascular surgery, Brookdale Hospital Medical Center
· Lucio Flores, Vascular surgery, Brookdale Hospital Medical Center

Learning objectives:
· Understand the clinical implications and management of late EVAR complications, including Type 1B endoleak and aortoenteric fistula.
· Explore the decision-making process in critically ill patients with multiple comorbidities and infected aortic grafts.
· Compare endovascular vs open surgical approaches in the setting of infected AAA, and when each is appropriate.
· Recognize the role of multidisciplinary collaboration in complex vascular cases.
· Discuss the ethical considerations and goals-of-care planning in high-risk, potentially terminal vascular patients.
· Highlight the importance of long-term surveillance after EVAR and the consequences of noncompliance.
