CX Aortic Vienna (8–11 September, virtual) hosted a “Best of CX and all abstracts” session on Wednesday, highlighting some of the more impactful and prominent work in the aortic space.

This session, and all other sessions from day one of CX Aortic Vienna, is available to view on demand. Click here to register and access the recording.

Presenting first, Gergana T Taneva (Madrid, Spain) talked the CX Aortic Vienna audience through her team’s long-term experience of chimney/snorkel endovascular aneurysm repair (chEVAR) in complex aortic pathologies, using patient data from the PERICLES registry.

Concluding, Taneva is positive about the technique: “ChEVAR showed good long-term branch patency, with over 90% of the vessels patent at five years’ follow-up. We did not identify anatomical or technical factors predicting branch occlusion or stenosis. The occurrence of late type 1a endoleak following chEVAR was relatively low, and occurred more frequently in patients with larger native neck diameters (>30mm), or with a complete absence of infrarenal neck. ChEVAR seems safe and feasible, and is an alternative to FEVAR under appropriate patient and anatomical selection.”

Martin Hossack (Liverpool, UK) was next to speak, detailing his experience of open retroperitoneal repair for complex abdominal aortic aneurysms. He noted that open repair of complex aneurysms carries a significant morbidity and mortality, regardless of approach. “With this in mind, patients should be considered for complex endovascular repair. However, patient and anatomical characteristics may favour open surgery. The retroperitoneal approach facilitates a more proximal clamp zone, with similar perioperative mortality and morbidity as transperitoneal approaches using more distal clamp zones,” Hossack concluded.

Closing the session, Petroula Nana (Larissa, Greece) discussed how 10-year data on elective endovascular repair of infra-renal abdominal aortic aneurysms performed at her institution demonstrate “good, long-term survival outcomes” of the procedure. She closed her talk with the following comments: “The procedure has low re-intervention rates—limb occlusion is an early common indication for re-intervention—and advanced age (over 80 years) may be associated with higher mortality.”
