Abstract

Summary:Background: Ruptured juxtarenal aortic aneurysms (RJAAA) represent a special challenge in clinical practice, but the evidence to guide therapeutic decision-making is scarce. The aim of this study was to present two different approaches, open surgical (OAR) and chimney endovascular repair (CHEVAR), for treating patients with RJAAA. Patients and methods: This retrospective two-center study included all patients per center undergoing OAR or CHEVAR for RJAAA between February 2008 and January 2020. Juxtarenal aortic aneurysms were defined as having an infrarenal neck of 2–5 mm, measured after three-dimensional reconstruction of the computed tomography angiography scan. Results: 12 OAR patients (10 male, median age 73 years [58–90 years]) and 6 CHEVAR patients (all male, median age 74 years [59–83 years]) were included. In the OAR group, the proximal aortic clamping was suprarenal in 7 and interrenal in 5 patients. Cold renal perfusion was used in 4 patients, in 2 with suprarenal aortic clamping and in 2 with interrenal aortic clamping. 3 CHEVAR patients received a single renal chimney, the other 3 received double renal chimneys. Technical success was 12/12 in the OAR group 5/6 in the CHEVAR group. In-hospital mortality and 30-day mortality were 3/12 after OAR and 0/6 after CHEVAR. 2 OAR patients required transient dialysis. Median in-hospital stay was 14 (10–63) and 8 (6–21) days and median follow-up (FU) was 20 (3–37) and 30 (7–101) months, respectively. No further deaths occurred during FU. One OAR patient and 4 CHEVAR patients required aortic reinterventions. Conclusions: RJAAAs are rare. Both OAR and CHEVAR can represent adequate treatments for RJAAAs. OAR is the traditional approach, but CHEVAR has - in a high-volume center - promising early results with nonetheless a need for continuous FU to prevent reinterventions. Defining the studied aortic pathology precisely is essential for future research in order to draw valid conclusions.
