[Interrupted aortic arch: fortuitous diagnosis in a 72-year-old female patient with severe aortic insufficiency]. / Der unterbrochene Aortenbogen: Zufallsdiagnose bei einer 72jährigen Patientin mit schwerer Aorteninsuffizienz.

Interrupted aortic arch, defined as complete luminal and anatomic discontinuity between ascending and descending aorta, is an uncommon and highly lethal anomaly. We report the case of a 72-year-old woman scheduled for aortic valve replacement because of severe regurgitation. During preoperative catheterization, it was not possible to reach the ascending aorta from a femoral puncture. Further radiological investigation demonstrated interrupted aortic arch of type A without other cardiac or vascular anomalies. Postoperative course after aortic valve replacement and ascending-to-supraceliac aortic bypass was initially uneventful. Unfortunately, pericardial tamponade developed 10 days after the operation and required re-exploration, during which no active bleeding could be found. Recurrent effusion occurred and the patient finally died from severe shock and multiorgan failure. This exceptional case prompted a review of the literature which confirmed the rarity of this presentation in adult patients. It seems interesting that only mild arterial hypertension of the upper extremities was retrospectively found in this patient.
