Key result
FET and TEVAR emerge as the preferred invasive strategies for non-A non-B aortic dissection.
Why the study?
Non-A non-B aortic dissection remains complex and controversial with limited evidence and guideline recommendations, leading to varied management approaches.
Does invasive surgical or endovascular management improve clinical outcomes compared to conservative therapy in patients with non-A non-B aortic dissection?

This narrative review highlights that while early treatment is controversial, the frozen elephant trunk procedure and TEVAR are evolving as the standard surgical modalities for managing high-risk or complicated non-A non-B aortic dissections.
Supports FET and TEVAR for complicated non-A non-B dissection; extends guidelines but leaves open RCTs versus medical therapy.
Non-A non-B aortic dissection remains a complex and controversial topic in cardiovascular management, eliciting varied approaches among cardiologists and surgeons. Due to the limited evidence surrounding this condition, existing guidelines are limited in the complexity of their recommendations. While most patients are initially managed medically, invasive treatment becomes necessary in a large proportion of patients. When surgery is considered, the most utilized techniques include the frozen elephant trunk procedure and endovascular repair strategies targeting the arch and descending thoracic aorta. This narrative review aims to synthesize current knowledge and clinical experiences, highlighting the challenges and evolving practices related to non-A non-B dissection management.

Kletzer et al. (2024) conducted a review in Non-A non-B aortic dissection. Surgical and endovascular management (Frozen Elephant Trunk, TEVAR) vs. Conservative medical management was evaluated. The frozen elephant trunk procedure and thoracic endovascular aortic repair are the preferred surgical approaches for managing non-A non-B aortic dissection when invasive treatment is indicated.
