Mid-term Outcomes of Stent Assisted Balloon Induced Intimal Disruption and Relamination in Aortic Dissection Repair (STABILISE) in Acute Type B Aortic Dissection
Résumé
Objectives: This article reports mid-term results of 41 patients treated by the stent assisted balloon induced intimal disruption and relamination (STABILISE) technique for acute type B aortic dissection.
Methods: Between November 2011 and November 2017, 41 patients (10 male; median age 50 years) underwent proximal descending aortic stent grafting plus stent assisted balloon induced intimal disruption of the thoraco-abdominal aorta for acute type B aortic dissection. Serial computed tomography angiography was used to assess aortic remodelling.
Results: There were no intra-procedural complications. Fifteen branch arteries supplied by the false lumen were stented (9% of the visceral branch arteries). The thirty day incidence of death, stroke, and paralysis/visceral ischaemia was 2% (n = 1), 0%, 5% (n = 2), and 2% (n = 1) respectively. During a median follow up of 12 months (range 1–168) eight patients (20%) required re-intervention. Primary visceral stent patency was 93% (n = 14). No aortic related deaths occurred. On the most recent computed tomography angiogram, complete false lumen obliteration and aortic remodelling was obtained in all patients at the thoraco-abdominal level, and in 39% (n = 16) at the unstented infrarenal aorto-iliac level. The maximum aortic diameter increased in only two patients (5%) at the unstented infrarenal level.
Conclusion: To obtain immediate and durable thoraco-abdominal aortic remodelling in acute type B dissections, the STABILISE technique is safe and reproducible while not compromising the patency of collateral branches.
