Abstract

Abstract
We present the case of a 16-year-old female with a history of thrombotic thrombocytopenic purpura (TTP) and recent pulmonary embolism (PE) who presented with hematochezia. Imaging revealed active hemorrhage from the ileocolic artery. Given the patient’s thrombocytopenia and anticoagulation therapy, surgical treatment was high risk. Selective embolization was performed successfully by interventional radiology, resulting in complete hemostasis. This case underscores the clinical complexity of managing gastrointestinal bleeding in pediatric patients with both bleeding and thrombotic risk factors.

Axial contrast-enhanced CT scan of the abdomen showing active extravasation of intravenous contrast in the ascending colon, indicating active lower gastrointestinal bleeding.
