This study presents an endovascular management technique for treating a specific type of endoleak occurring after branched aortic aneurysm repair. The misalignment of the stent graft is resolved through retrograde cannulation of the superior mesenteric artery, allowing for successful repair of the endoleak.
Purpose: The purpose of the study was to present an endovascular management of a type IIIc endoleak (EL) in a patient with migration of the bridging stent graft of the celiac trunk (CT) after branched aortic aneurysm repair with retrograde cannulation of the superior mesenteric artery (SMA). Technique: The therapy was applied in a 62-year-old man who underwent a branched EVAR 2 years ago. Meanwhile, the patient was treated due to type Ia EL 6 months ago. The patient suffered in the last days from unclear hemorrhage clinically correlated with weakness. In the computed tomography angiography (CTA), an EL IIIc with a migration of the bridging stent graft from the CT branch was displayed. As vascular access, the left axillar artery was used. Due to the misaligned bridging stent graft, an antegrade cannulation was impossible, so cannulation was performed retrograde through the SMA using pancreaticoduodenal and gastroduodenal arteries. Thereafter, the EL could be repaired with bridging stent grafts. The postinterventional control showed a satisfying reconstruction without EL or embolization. Conclusion: Most of the complications such as type IIIc EL after complex endovascular repair can also be treated endovascularly. This sophisticated treatment requires that necessary materials and experience are available.
