Key result
First-line PETTICOAT before proximal repair resolves visceral malperfusion in a patient with acute TAAD.
Why the study?
Patients with acute type A aortic dissection and mesenteric malperfusion have a higher in-hospital mortality risk than those without mesenteric malperfusion.
Does the PETTICOAT technique resolve visceral malperfusion in a patient with acute type A aortic dissection?
Does the PETTICOAT technique resolve visceral malperfusion in a patient with acute type A aortic dissection?
The PETTICOAT technique may be an effective first-line strategy to resolve visceral malperfusion before proximal repair in acute type A aortic dissection.

Mesenteric malperfusion in AAD carries high mortality; single-case PETTICOAT success leaves open need for prospective validation.
Patients with type A aortic dissection (AAD) and mesenteric malperfusion have greater in-hospital mortality risk than patients with AAD without mesenteric malperfusion (63% vs 24%).1 Using the PETTICOAT (provisional extension to induce complete attachment) technique as a first-line strategy before proximal repair, we resolved our patient's visceral malperfusion.
