Color Doppler echocardiography revealed Stanford type A: Debakey I AD, aortic regurgitation, and massive pericardial effusion; the aortic root was widened to 50 mm in diameter (Figure 1). Computed tomography (CT) revealed a widened mediastinum, significant dilation of the posterior part of the aortic root (~58 mm at its widest point) extending up to the aortic arch.

There was blood flow through the breach from the true to the false lumen (Figures 2, 3).

When the pericardium was opened, a large amount of hemorrhagic effusion was visible, and a huge aneurysm with a diameter of 5 x 4 cm could be seen in the posterior wall of the aortic root (Figure 4).

Two breaches, with diameters of 2 and 3 mm, were observed at the midpoint of the non-coronary sinus, which communicated with the aortic root aneurysm, and the surfaces of the breaches were rough with a few neoplasms visible (Figure 5).

We repaired the tear in the aorta with the artificial vascular patch (Figure 6).

Follow-up CT 4 weeks after surgery showed that the false lumen had disappeared (Figure 7).
