The outcome of late open conversion after endovascular abdominal aortic repair.
Asian Cardiovasc Thorac Ann

Department of Cardiovascular Surgery, Chiba University Hospital, Chiba, Japan.
Background: Endovascular abdominal aneurysm repair (EVAR) offers a less invasive approach to treating abdominal aortic aneurysms (AAA) compared to open repair. However, EVAR is associated with higher rates of reintervention. This study investigates the early and mid-term outcomes of patients who underwent late open conversion including aneurysmorrhaphy after EVAR at our institution.

Background: Current guidelines recommend preserving at least one of the bilateral pelvic flows in patients with aortoiliac aneurysms. The sandwich parallel graft, using commercially available devices, provides a viable option for patients who fall outside the instructions for use of iliac branch devices. However, gutter endoleak remains a significant challenge.

The purpose of this study is to evaluate the feasibility and clinical outcomes of vasa vasorum embolization for preventing continuous aneurysmal expansion after endovascular aneurysm repair (EVAR). We retrospectively reviewed the medical records of patients who underwent vasa vasorum embolization between August 2018 and May 2022. Vasa vasorum embolization was attempted in cases of continuous aneurysmal expansion after EVAR, where the vasa vasorum was identified through catheter angiography.

Objectives: We present a clinical case illustrating the feasibility of endovascular treatment of superior mesenteric aneurysm associated with an arteriovenous fistula.
Methods: The patient presented with abdominal pain and diarrhea on admission. Computed tomography angiography revealed an aneurysmal dilatation of the superior mesenteric artery and vein with an arteriovenous fistula.

Purpose: To evaluate ferumoxytol-enhanced magnetic resonance angiography (FE-MRA) for assessment of endoleaks in patients with abdominal aortic aneurysms (AAA) and chronic kidney disease (CKD) status post endovascular aneurysm repair (EVAR).
Methods: Of 1854 patients who underwent FE-MRA at a single institution between 03/21/2014 and 08/21/2023, 21 patients with a history of AAA and CKD status post EVAR were retrospectively identified (IRB #13-001341). Multiplanar pre- and post-contrast HASTE, T1-VIBE, and high-resolution breath-held 3D MRA sequences were obtained, where a dose of 4 mg/kg of Ferumoxytol was infused over six minutes.
