Unusual, Radical Treatment of Type A Aortic Dissection: A Case Report

Figures

• 

  Fig. 1. Contrast-enhanced computed tomography. ( A ) Axial section of the upper thorax shows the dissection flap (shown by red arrow) in the aortic arch. The true lumen is anterior (shown by red asterisks) and the false lumen is posterior; ( B ) coronal section of thorax and abdomen shows the Type A aortic dissection involving the ascending and abdominal aorta and proximal segment of the aortic arch, with an image of spiral intimal flap and “cobweb sign” of the false lumen (shown by red arrow).

  Fig. 2. ( A, B ) Volume rendering of entire aorta with the image of spiral intimal flap (shown by red arrows) dividing the true and false lumens and running parallel to the longitudinal axis of aorta ( C, D ) Volume rendering of the intrathoracic aorta; ( C ) posterior view with spiral intimal flap, showing the true and false lumen in the distal aortic arch; ( D ) axial section showing the true and false lumens in the ascending and descending aorta. The spiral intimal flap is shown by red arrows. The true lumen is shown by red asterisks.

  Fig. 3. ( A, B ) Postoperative two-dimensional echocardiogram: parasternal long axis view. ( A ) Native aortic valve sparing and reinforcement of the aortic root (shown by red arrows), ( B ) color flow mapping, in the parasternal long axis view, shows no aortic regurgitation. ( C, D ) Volume rendering of the thorax, left ( C ) and right ( D ) sagittal views, showing Vascutek Thoraflex hybrid prosthesis in aortic arch and descending aorta. The Vascutek Thoraflex is shown by white arrows.
