- Abstract:
Background: To investigate the value of dual-source CT combined with volumetric measurement in the follow-up of Stanford Type B aortic dissection (TBAD) intrathoracic aortic repair (TEVAR).
Methods: 40 TBAD patients in our hospital were treated with TEVAR and followed up at 3, 6 and 12 months after surgery. Dual-source CT and volumetric measurements were used to calculate the diameters and areas of the true and false lumen and the total lumen of the left subclavian artery at a distance of 2 cm (P1), the middle part of the descending aorta (P2), the opening of the abdominal trunk (P3) and the anterior bifurcation of the abdominal aorta (P4) before and after surgery. The maximum diameter, maximum area, volume and modified aortic remodeling index (MARI) of the true and false lumen of the distal abdominal aortic dissection were measured to evaluate the postoperative vascular remodeling.
Results: The true cavity diameter of P1 and P2 increased gradually, the false cavity diameter decreased gradually (P < 0.05), and the total and true cavity diameter of P3 and P4 increased (P < 0.05). After operation, the true cavity area of P1 and P2 gradually increased, and the false cavity area decreased (P < 0.05). The total area of P3, P4, and true cavity increased gradually after operation (P < 0.05). There were statistically significant differences in true and false lumen volume and MARI before and after surgery (P < 0.05).
Conclusion: Compared with diameter measurement and area measurement, volume measurement can more accurately reflect the remodeling of the true and false lumen of the uncoated aortic dissection.
