Helicobacter pylori Eradication Therapy for Thrombocytopenia after Surgery for Abdominal Aortic Aneurysm with Disseminated Intravascular Coagulation

摘要

Abdominal aortic aneurysm (AAA) is known to be rarely accompanied by disseminated intravascular coagulation (DIC). We report a case of AAA with DIC. An 81-year-old man with abdominal pain referred to our hospital. Computed tomography demonstrated an AAA (maximum diameter: 90 mm). The patient underwent a laparotomy, and an abdominal aorta replacement was performed. At the 3-month follow-up, the patient underwent Helicobacter pylori eradication treatment for 1 week. After treatment, the platelet count dramatically increased. The mechanism by which H. pylori eradication therapy improves hematological parameters has not been elucidated; however, this noninvasive treatment effectively resolved DIC associated with AAA.
