FL embolization of the distal thoracic aorta is a promising technique to promote FL thrombosis and aortic remodeling in a group of patients with thoracic aortic dissection.
Background: To provide a contemporary review on endovascular false lumen (FL) emboliza-tion for thoracic aortic dissection (AD) and evaluate its early outcome.Methods: A systematic literature review on FL embolization for thoracic AD from January 2003 to December 2020 was performed under the instruction of Preferred Reporting Items for Sys-tematic Reviews and Meta-Analyses (PRISMA) statement. Each article was analyzed using a standardized protocol including predefined demographic characteristics, perioperative mortality, and major complications.Results: A total of 29 papers with 229 patients were included into the analysis. The methods of FL occlusion used were the candy-plug technique, the knickerbocker technique, the cork in the bottlenecktechnique, and direct FL embolization with a combination of stent-grafts, coils, onyx, plugs, and glue. FL embolization procedure was performed in 79 patients (34.5%) with type A AD and 150 (65.5%) with type B AD. FL direct embolization was the most frequently used tech-nique and it was applied in 198 (86.5%) patients. Candy-plug, knickerbocker, and cork in the bottlenecktechniques were used in 26 (11.4%), 3 (1.3%), and 2 (0.9%) patients, respectively. Technical success was achieved in all patients except one (228/229, 99.6%) in which implanta-tion of a stent to celiac trunk was not possible. There were 4 hospital deaths (1.7%). Neurolog-ical complications occurred in 6 patients (2.6%), including 4 (1.7%) spinal cord ischemia and 2 (0.9%) ischemic stroke. There were 1 (0.4%) iatrogenic retrograde dissection and 2 (0.9%) renal failure reported. The mean duration of follow-up was 16.5 months. There were 21 deaths (9.3%) during follow-up and 8 (3.6%) were aorta-related. Thirty three (14.7%) secondary interventions were performed. Five patients (2.2%) required an open completion thoracoabdominal procedure incorporating the stent-graft into the repair. Complete FL thrombosis was observed in 181 (80.4%) patients, 34 (15.1%) had partial thrombosis, and 10 (4.4%) had FL progression.Conclusions: FL embolization of the distal thoracic aorta is a promising technique in a group of patients to promote FL thrombosis and aortic remodeling in thoracic aorta.
