Statistics. We used JMP software from SAS (versions 13 or 14) for all analyses. Data are presented with all data points plotted. Overlayed diamonds represent mean, 95% CI, and overlap marks (horizontal lines above and below the mean line), which define statistical significant difference between groups if not overlapping (P < 0.05). Groups were compared with 1-way ANOVA, applying a Tukey-Kramer posttest correcting for multiple comparisons. A P value of less than 0.05 was considered statistically significant.Study approval. All animal studies were approved by the cantonal veterinary authorities "Kantonale Tierversuchskommission Zürich." The clinical study (CSF sampling) was approved by the local ethical review board of the Kanton of Zurich, and written consent was obtained from all patients or their legal representatives.

Innominate artery (IA) aneurysms represent 3% of all arterial aneurysms. Due to the risk of thromboembolic complications and spontaneous rupture, surgical repair is usually recommended on an early elective basis. We present the case of 81-year-old Caucasian male presenting with atypical anterior chest pain secondary to a large innominate artery aneurysm who underwent successful open surgical repair at our institution. In our experience, open correction via median sternotomy with extension into the right neck provides excellent exposure and facilitates rapid reconstruction with good short and long-term outcomes. Minimally invasive and endovascular approaches provide emerging alternatives to open IA aneurysm repair, however further research is required to better define optimal patient selection criteria and determine the long-term outcomes of these novel therapies.
