Adolescent Acute Pancreatitis Complicated With Pseudoaneurysms and Venous Thrombosis

Vascular complications, such as pseudoaneurysms and thrombosis, are uncommon in pediatric acute pancreatitis (AP); hence, treatment experience remains limited. Here, we report a case of adolescent AP complicated with pseudoaneurysms and venous thrombosis simultaneously. Even after multiple endovascular embolizations for pseudoaneurysms, the patient experienced hemorrhagic shock resulting from pseudoaneurysm rupture after taking anticoagulants for thrombus. Inevitably, a total pancreatectomy was performed to prevent bleeding and control local complications. In AP, even among the pediatric population, a therapeutic dilemma between bleeding prevention and anticoagulation for thrombosis may occur. Despite the lack of experience with AP and its complications, a total pancreatectomy may become an alternative therapy for refractory AP or its complications.
