Successful Management of Prolonged Thrombocytopenia After Surgery for Abdominal Aortic Aneurysm With Disseminated Intravascular Coagulation.

We report a case of an infrarenal abdominal aortic aneurysm that developed acute onset thrombocytopenia and disseminated intravascular coagulation (DIC) after a previous coronary artery bypass grafting. Open surgical intervention was successfully performed for the treatment of aortic aneurysm; however, thrombocytopenia and enhanced-fibrinolytic-type DIC were prolonged even after the surgery, and improved after Helicobacter pylori eradication therapy and medication with warfarin and oral tranexamic acid. Surgical intervention alone was not effective as a treatment for DIC associated with aortic aneurysm, and multidisciplinary management was necessary for the optimization of the coagulation and fibrinolytic systems, even after successful surgery.
