A new clinical case to keep learning with colleagues!

Today, we present a Thoracic Aortic Dissection in Patient with Complex Arch. This is the 4th case for SOLACI Peripheral, which continues its mission: to deepen knowledge exchange among Latin American interventional cardiologists.

33-year-old male patient with Ehlers-Danlos syndrome, prior hemorrhagic stroke in 2008 (which required an embolization), and multiple atlas and lumbar fractures.

Patient experiences chest pain and dyspnea. A Stanford type A and DeBakey type I thoracic aortic dissection is documented, with severe aortic and mitral regurgitation. His CT imaging is as follows:

Given the context, what would you choose?

  1. Surgical intervention.
  2. Endovascular treatment.
  3. Another option.

If you were to conduct a surgical intervention, which surgical path would you take?

  1. Aortic valve replacement + mitral valve replacement + Complete repair of ascending aorta and arch with reimplantation of supra-aortic vessels.
  2. Mitral valve replacement + Bentall-De Bono procedure.
  3. Another option.

The patient undergoes a successful mitral valve replacement and Bentall-De Bono procedure (ascending aorta repair with aortic valve replacement).

After removing the mechanical ventilation support 24 hours after the procedure, the patient experiences an 8-9/10 persistent chest pain. CT imaging shows dissection expansion.

At this point, it is decided to…

  1. Conduct a complete endovascular treatment.
  2. Perform a revascularization of supra-aortic vessels + endovascular treatment at a second instance.

A decision is made to revascularize supra-aortic vessels to prepare for an endovascular repair. Post-revascularization control imaging showed the following findings.

On and off chest pain continues.

Endovascular procedure: Right femoral surgical approach and right radial percutaneous approach with 7-6 Fr Slender.

Multipurpose catheter with a 300-cm hydrophilic guidewire, then exchanged for a pigtail catheter. An angiography is conducted.

The device is later exchanged for a Lunderquist guidewire. The aortic graft and supra-aortic vessels are reached through transradial access to mark the landing zone.

Initially, a Relay prosthesis (34-162 mm) is inserted. During insertion, resistance is felt.

Given the resistance:

  1. You change it for another prosthesis adapted to planned measures, or
  2. You stick to the same model.

Physicians decide to insert a Valiant 32-204 prosthesis.

At first, the prosthesis cannot be inserted, so a Relay 32-114 is used and positioned.

Ultimately, the Valiant prosthesis is positioned within the descending aortic artery. The final result is shown.

The final video shows the follow-up image 1 year after the procedure. FIGURE 3.

Taking into account the diagnostic TC imaging and considering the patient’s anatomical characteristics:

Which treatment possibilities would you have considered?

  1. Complete surgical approach: aortic mitral valve replacement and complete surgical aortic arch repair.
  2. Mitral valve replacement and Bentall-De Bono procedure, outcome assessment and complete arch endovascular treatment.
  3. Mitral valve replacement and Bentall-De Bono procedure, and simultaneous supra-aortic vessel revascularization.
  4. Mitral valve replacement, Bentall-De Bono procedure, revascularization at a second instance, and endovascular treatment as a third instance.
