Arterial Embolization for the Management of Gastrointestinal Hemorrhage from Metastatic Renal Cell Carcinoma

Patients with renal cell carcinoma (RCC) involving the gastrointestinal (GI) tract may present with hemorrhage. Eight arterial embolization procedures were performed to treat five upper GI lesions and one ileal metastatic RCC lesion in five patients with GI bleeding. Control of GI hemorrhage for at least 30 days was achieved following six of the eight embolizations (75%) in four of the five patients (80%). Duration of response ranged from 1 to 26 months. Complications including GI ischemia and nontarget embolization were not encountered. Arterial embolization can be used safely for palliation of hemorrhage from RCC metastases to the GI tract.
