Objectives We represent two cases of late proximal type I endoleak following EVAR with aneurysm expansion that were treated with a custom-made graft with inner branches. Methods Two patients of 87 and 82 years old were operated by EVAR 6 and 8 years ago for abdominal aortic aneurysm. Both had proximal type I endoleak with aneurysm sac expansion. Open surgery had a high risk, and a proximal aortic extension with a simple aortic cuff was not possible neither because previous EVAR grafts were already at the level of the renal arteries. A custom-made endograft with inner branches was planned as a fenestrated graft was not technically possible. Results We successfully treated both patients using a custom-made graft with four inner branches from Jotec (Cryolife, Kennesaw, GA). Three months’ follow-up CT scan did not show any endoleaks. All target vessels were patent with good conformability of the bridging stents. Conclusion The treatment of proximal type I endoleak using inner branches’ endografts is feasible. This novel technology might broaden the indications for complex aortic repair in a group of patients where fenestrated endografts are not possible.

Purpose: To report a late complication associated with embolization coils used to treat an endoleak after endovascular abdominal aortic aneurysm (AAA) repair. Case Report: A 79-year-old man with a 5.8-cm AAA underwent endovascular repair with an Ancure graft in 1997. A persistent type I endoleak was identified on serial postoperative computed tomographic scans. Three transarterial coil embolization procedures were performed to treat an endoleak from the proximal and right distal attachment sites with outflow by the inferior mesenteric and lumbar arteries. Coil embolization was ultimately successful in sealing the endoleak, and the AAA decreased in size. Four years later, the patient developed an aortoenteric fistula due to erosion of the metallic embolization coils into the duodenum. The endograft was explanted and an extra-anatomical bypass inserted. Conclusions: Coil embolization to treat endoleaks can, on rare occasions, be the cause of aortoenteric fistula. Lifelong follow-up of stent-graft patients is required.

Abdominal Aortic Dissection

We present two cases of infrarenal abdominal aortic dissection (IAAD) that were treated by endovascular aortic repair (EVAR). The EVAR procedure was successful, although one patient developed a proximal Type I endoleak several months after the procedure; both patients remain symptom-free more than 24 months after surgery. A literature search revealed that EVAR has been performed in only 14 cases of IAAD. Based on these 14 cases, we believe EVAR is feasible and effective for the treatment of IAAD. Moreover, this treatment strategy represents a reasonable alternative to open surgery, especially in cases of complicated juxtarenal abdominal aortic dissection.

Type I Endoleak

For all abdominal aortic aneurysm endografts, the major challenge is minimizing the risk of a type I endoleak. Percutaneous placement of an abdominal aortic endograft has become a widely-performed procedure. With several devices available on the market, there are many device-specific and experience-based considerations in planning and performing these procedures safely and with good outcomes. Although not always evidence-based, reviewing some case-specific scenarios can introduce techniques or lead to standards of practice that reduce suboptimal outcomes or prevent complications in future procedures. This chapter discusses deployment finesse of the Cook Zenith Flex and Zenith LP stent grafts, but many of the described concepts apply to other abdominal endografts and even thoracic endograft procedures.

Purpose: To describe the application of uncovered chimney stent grafts with the Nellix endovascular aneurysm sealing technique (ChEVAS) for juxtarenal abdominal aortic aneurysms (JAAAs). Case Report: Two patients with JAAA and multiple comorbidities were considered unfit for open surgery and were selected for an endovascular approach. Fenestrated and branched endografts were too expensive, and a chimney endovascular approach was considered inappropriate for the relatively high incidence of proximal type I endoleak and graft migration. ChEVAS was performed successfully with the novel addition of uncovered chimney stents to further reduce costs and possibly improve target vessel patency. JAAA exclusion and visceral vessel patency was confirmed at 18-month follow-up. Conclusion: ChEVAS with bare chimney stents is technically less complex, potentially reduces access complications and procedural costs, and may improve long-term patency compared to alternative techniques. Results at 18 months seem promising, but strict follow-up is necessary as the long-term durability is unknown.

Good Clinical Condition

We report a clinical evolution of a 85-years old male admitted to our Emergency Department for ruptured abdominal aortic aneurysm (rAAA). One month later a huge type I proximal endoleak was detected and corrected by proximal aortic extension. We decided to fix the stent-graft to the aortic wall using EndoAnchors. However, an asymptomatic type III endoleak due to controlateral limb disconnection was detected at the followed schedulated CT angio and corrected by a relining of the endograft. The patient is now in good clinical condition with no evidence of endoleaks at 1-year follow-up.
