Acute Ischemic Pancreatitis Secondary to Aortic Dissection

Background: Acute ischemic pancreatitis secondary to aortic dissection is very rare with an unclarified mechanism. We retrospectively reviewed 6 such cases in our center and present their outcomes herein. Methods: Between February 2009 and April 2017, 6 patients (male = 2 and female = 4; mean age, 58 ± 8 years [range, 47–70 years]) with acute aortic dissection associated with pancreatitis were admitted to our center. There were 3 type A and 3 type B dissections. One patient developed renal dysfunction and visceral organ ischemia, and 1 developed renal failure and ischemia of the lower extremity. Five patients had a history of hypertension, and 1 had diabetes mellitus. Results: After aggressive medical treatment, 5 patients survived the acute phase of aortic dissection and acute ischemic pancreatitis. Surgery was required in 4 patients and thoracic endovascular aortic repair in 1 patient. There were no severe postoperative complications, and all 5 were discharged. One patient with acute type B dissection refused treatment and died from multiple organ failure. No complications or deaths occurred in the postoperative follow-up period. Conclusions: Acute ischemic pancreatitis after aortic dissection is a very unusual complication. The potential for this concomitant diagnosis should always be considered during the diagnostic stages. There is no clear consensus regarding the management of aortic dissection associated with acute pancreatitis.
