Purpose: To report the successful endovascular occlusion of a persistent endoleak owing to collateral perfusion in a 1-year-old bifurcated aortic endograft. Methods and Results: An 81-year-old man underwent endovascular repair of a 5.5-cm abdominal aortic aneurysm (AAA) with a bifurcated stent-graft in 1995; collateral perfusion of the excluded aneurysm by retrograde filling of the patent inferior mesenteric artery (IMA) was noted postoperatively. At his 1-year follow-up, the mid-sac endoleak persisted on contrast-enhanced computed tomography. Using the superior mesenteric artery for access, the stump of the IMA was successfully embolized with glue. Conclusions: This case, which highlights the importance of documenting a patent IMA prior to AAA endografting, illustrates one option for the management of persistent collateral perfusion of endovascularly excluded aneurysms.

An 82-year-old man was transferred to our emergency department due to acute abdominal pain. He had undergone an endovascular abdominal aortic aneurysm repair (EVAR) six years ago. An intravenous contrast-enhanced abdominal computed tomography revealed the rupture of the abdominal aortic aneurysm (AAA) with a large retroperitoneal hematoma. A Talent (Medtronic, Santa Rosa, CA, USA) modular bifurcated endoprosthesis had vertically collapsed approximately 7 cm after losing its infrarenal fixation. As a result, it led to the repressurization of the aneurysm sac and rupture. The patient was successfully treated by placing three Talent (Medtronic) aortic cuffs. To our knowledge, this is the first reported case of endograft collapse that has manifested with aortic aneurysm rupture. Although they are gradually declining, considerable rates of complications create the ‘Achilles’ heel' of endovascular repair of AAAs. A lifelong follow-up strategy for patients treated for AAA with EVAR is essential for the early detection and treatment of complications of the procedure.

Abstract Objective: To compare duplex ultrasound and computed tomography (CT) angiography in terms of their performance in detecting endoleaks, as well as in determining the diameter of the aneurysm sac, in the postoperative follow-up of endovascular abdominal aortic aneurysm repair. Materials and Methods: This was a prospective study involving 30 patients who had undergone endovascular repair of infrarenal aortoiliac aneurysms. Duplex ultrasound and CT angiography were performed simultaneously by independent radiologists. Measurements of the aneurysm sac diameter were assessed, and the presence or absence of endoleaks was determined. Results: The average diameter of the aneurysm sac, as determined by duplex ultrasound and CT angiography was 6.09 ± 1.95 and 6.27 ± 2.16 cm, respectively. Pearson's correlation coefficient showing a statistically significant correlation (R = 0.88; p < 0.01). Comparing the duplex ultrasound and CT angiography results regarding the detection of endoleaks, we found that the former had a negative predictive value of 92.59% and a specificity of 96.15%. Conclusion: Our results show that there is little variation between the two methods evaluated, and that the choice between the two would have no significant effect on clinical management. Duplex ultrasound could replace CT angiography in the postoperative follow-up of endovascular aneurysm repair of the infrarenal aorta, because it is a low-cost procedure without the potential clinical complications related to the use of iodinated contrast and exposure to radiation.
