Severe Acute Type B Aortic Dissection Complicated by Acute Pancreatitis: A Case Report

A 52-year-old man presented with sudden abdominal pain and intermittent vomiting. The patient underwent contrast-enhanced computed tomography scan and was diagnosed with an acute type B aortic dissection involving the celiac trunk superior mesenteric artery and extending to the renal artery. The patient was treated with thoracic endovascular aortic repair. After the procedure, the patient still complained of left upper abdomen abdominal pain, and an abdominal mass was detected on physical examination. Imaging revealed a 15-cm cystic lesion involving the pancreatic tail and serum amylase measured at 556 U/L. A definitive diagnosis of severe acute pancreatitis was made. The patient was treated with injection of somatostatin, ultrasound-guided puncture drainage, and jejunal nutrition tube placement. The patient was discharged with symptom free after 30 days and well recovered in subsequent follow-up 12 months later.
