Abstract

Background/Purpose: Data about volumetric remodeling of the provisional extension to induce complete attachment (PETTICOAT) technique on DeBakey type IIIb aortic dissection in acute and subacute phases were scarce. The proper timing to perform this technique to promote false lumen reduction was also unknown. Methods: Patients with DeBakey type IIIb aortic dissection who underwent the PETTICOAT technique between December 2005 and March 2017 were reviewed and divided into acute (treatment occurred ≦14 days after symptom onset) and subacute (15–90 days) groups. Remodeling parameters of the true and false lumens were analyzed. Receiver operating characteristic curve was used to deduce the timing of this technique. Results: In the 2-year follow-up, the acute group (N = 20) demonstrated significant true lumen expansion and false lumen regression in the thoracic, abdominal, and total aorta. However, the subacute group (N = 20) only showed significant shrinkage in the false lumen of the thoracic and total aorta. Using PETTICOAT technique within 36 days after the aortic event may result in better total false lumen reduction. Conclusion: For DeBakey type IIIb aortic dissection, more prominent true lumen expansion and false lumen reduction were noted when using the PETTICOAT technique in the acute phase. When performed within 36 days after symptoms onset, the PETTICOAT technique may potentiate better total false lumen regression.
