DEDICATIONAfter studying medicine at Hanover Medical School and philosophy and social psychology at the Leibniz University Hanover, Omke E. Teebken joined the Christian Albrechts University in Kiel at the end of the 1990s as a research fellow at the Clinic for Cardiovascular Surgery headed by Professor Dr Axel Haverich, whom Omke E. Teebken later followed back to Hanover.In Hanover, besides working as a clinician, Omke E.Teebken was particularly active scientifically, contributing to the establishment of the then newly founded Leibniz Laboratories for Biotechnology and Artificial Organs (LEBAO). His work focused on regenerative medicine and tissue engineering, and subsequently he wrote his habilitation thesis in in this field. After basic training in cardiac surgery, he specialised clinically in vascular surgery and played a pioneering role in the development of this field. Before being appointed director of the Clinic for Vascular Surgery e Endovascular Surgery at the Peine Clinic in 2016, Omke E. Teebken headed the Vascular Surgery e Endovascular Surgery Division of the Department of Cardiothoracic, Thoracic, Transplantation and Vascular Surgery at Hanover Medical School. Professor Teebken was a highly appreciated, committed, and competent colleague and teacher.On 8 April 2019, Professor Teebken passed away after a short and severe illness. He was member and author of the ESVS guideline writing committee, an esteemed colleague, and friend.We will always honor his memory.

WHAT THIS PAPER ADDS This multicentre study suggests that in fit patients, open juxtarenal abdominal aneurysm repair can be performed with acceptable operative risk and with durable results in terms of both graft integrity and preservation of renal function. Predictors of acute kidney injury (AKI) were pre-existing chronic kidney disease, diabetes, hypertension, and age. The level and duration of renal artery clamping (24 AE 7 min, range 10e55 min) were not associated with an increased risk of AKI in this group of fit patients. Objectives: With a focus on renal function, the goal of this multicentre study was to assess peri-operative complications and late mortality of open surgical repair (OSR) of juxtarenal abdominal aortic aneurysms (JRAAA). Methods: From February 2005 to December 2015, 315 consecutive patients undergoing elective OSR of a JRAAA in five French academic centres were evaluated retrospectively. The definition of JRAAA was an aortic aneurysm extending up to but not involving the renal arteries, i.e., a short neck <10 mm. End points included postoperative death; acute kidney injury (AKI) defined by the RIFLE (Risk, Injury, Failure, Loss of function, End stage renal disease) criteria; and long term follow-up with freedom from chronic renal decline (CRD) and any graft related complications. Factors predictive of renal insufficiency were determined by multivariable analysis. Results: Of 315 patients, 292 (92.6%) were men (mean age 68 AE 8 years), and 73 (23.2%) had baseline chronic kidney disease (CKD) with an estimated glomerular filtration rate of <60 mL/min/1.73 m 2. The level of aortic clamping was supracoeliac (n ¼ 11), suprarenal (n ¼ 235), or inter-renal above one renal artery (n ¼ 69).The mean duration of renal artery clamping was 24 AE 7 min (range 10e55 min). Eleven patients (3.5%) presented with a renal artery stenosis that was treated conservatively. Perfusion of the renal arteries with a chilled Ringer's solution was used selectively in seven patients (2.2%). The overall 30 day mortality was 0.9% (three patients). AKI occurred in 53 patients (16.8%). Nine patients (2.9%) required temporary dialysis and one patient required chronic dialysis. Predictors of AKI were preexisting CKD (odds ratio [OR] 2.25, 95% confidence interval [CI] 1.13e4.48; p ¼ .021], diabetes (OR 3.15, 95% CI 1.48e6.71; p ¼ .003), hypertension (OR 3.38, 95% CI 1.33e8.57; p ¼ .01), and age (OR 1.05, 95% CI 1.01e1.10; p ¼ .014). The level of aortic clamping and duration of renal artery clamping were not associated with an increased risk of AKI. The KaplaneMeier survival estimate was 71% AE 5% at five years. Predictors of CRD during follow up were AKI (hazard ratio [HR] 15.81, 95% CI 5.26e47.54; p ¼ .001), diabetes (HR 4.56, 95% CI 1.57e13.17; p ¼ .005), and pre-existing CKD (HR 2.93, 95% CI 1.19e7.20; p ¼ .019), with freedom from CRD of 89% AE 3% at five years. Surveillance imaging was obtained by computed tomography angiography in 290 patients (92.6%) at a mean follow up of 4.3 AE 2.4 years. Renal artery occlusion occurre...
