- Focuses on outcomes of fenestrated-branched endovascular repair for postdissection thoracoabdominal aortic aneurysms (PD-TAAAs) with a narrow true lumen (NTL), using data from the international NADIR registry.
- Finds that 80% of the 544 patients had an NTL, defined as true lumen diameter <25 mm, with these cases associated with more complex procedures but similar technical success and 30-day mortality compared to those without NTL.
- Reports that patients with NTL had higher rates of reinterventions, particularly false lumen embolization, and that an NTL diameter <10 mm was a risk factor for target vessel instability, while the use of inner branches and bridging stent reinforcement were protective.
