Background: Fenestrated endovascular aneurysm repair (FEVAR) provides an endovascular solution for patients with large abdominal aortic aneurysms and challenging neck anatomy in addition to repair of endoleaks and pseudoaneurysms. This article reports the midterm outcomes of FEVAR from a single-tertiary referral centre in Ireland.
Methods: From 2006 to 2012, nine consecutive asymptomatic patients with neck anatomy unfavourable for standard EVAR underwent endovascular repair with a customised fenestrated Zenith stent graft. An additional three patients had fenestrated grafts for repair of pseudoaneurysms (n = 2) following open AAA repair and a type I endoleak (n = 1). All patients were prospectively enrolled in a computerised database. Outcomes including mortality, morbidity, renal function, target vessel patency, endoleak and reintervention were analysed.
Findings: The mean age and aneurysm size in the primary repair group were 74 years (65-84 years) and 6 cm (5-8.3 cm), respectively, and in the secondary repair group, the mean age was 66 years (61-75 years). No procedures required open conversion, and no visceral arteries were lost. On completion angiography, two patients in group 1 had a type I endoleak and one had a type III endoleak. There were no endoleaks in the secondary repair group. Follow-up ranged from 30 days to 6 years. There was one death within 30 days (8 %) and two deaths at 3 years from non-aneurysm-related causes. Six patients required secondary interventions. Three patients had a transient post-operative creatinine rise of >30 %.
Conclusion: Our study supports FEVAR as a feasible and effective therapy in the management of patients with complex aortic aneurysms.

We describe a patient with an asymptomatic infrarenal abdominal aortic aneurysm. Treatment decisions were complicated by the presence of a left congenital pelvic kidney supplied by two renal arteries originating from the proximal common iliac arteries bilaterally and respiratory status that was prohibitive to open repair. A hybrid surgical repair was performed with a bifurcated aortic endograft and parallel grafting to revascularize the pelvic renal arteries.

Despite advancements in surgical techniques and critical care, managing complications of type A and B aortic dissections remains challenging. Common morbidities include paraplegia, renal failure, stroke, and intestinal ischemia. Risks are especially high in extensive repairs, such as Crawford extent II thoracoabdominal aortic aneurysms, and in older patients or those with heart failure, poor pulmonary function, or renal disease.

Objectives: Celiac artery (CA) incorporation during FB-EVAR for complex abdominal aortic aneurysms (cAAA) is typically performed with fenestrations. Double-wide scallops (DWS) can be used when appropriate. We aimed to assess outcomes of patients treated with DWS for the CA during FB-EVAR for cAAA.

Background And Aim: Our previous research indicates that sarcoplasmic/endoplasmic reticulum calcium ATPase 2 (SERCA2) dysfunction facilitates the phenotypic transformation of aortic smooth muscle cells (ASMCs) and intensifies aortic aneurysm through the regulation of calcium-dependent pathways and endoplasmic reticulum stress. Our hypothesis is that additional mechanisms are involved in aortic aneurysm and atherosclerosis induced by SERCA2 dysfunction from the perspective of ASMC phenotypic transformation.
Methods & Results: In SERCA2 dysfunctional mice and their control littermates, ASMCs were isolated to analyze protein expression and cell functions, and angiotensin II was infused into these mice that were backcrossed into LDL receptor deficient background to induce aortic aneurysm and atherosclerosis.

Objective: Cloud-based, surgical augmented intelligence (Cydar Medical, Cambridge, UK) can be used for surgical planning and intraoperative imaging guidance during complex endovascular aortic procedures. We aim to evaluate radiation exposure, operative safety metrics, and post-operative renal outcomes following implementation of Cydar imaging guidance using a manually matched cohort of aortic procedures.
Methods: We retrospectively reviewed our prospectively maintained database of endovascular aortic cases.
