Staged surgical treatment of a primary duodenocaval fistula in a patient with metastatic nonseminomatous germ cell tumor

Abstract

Endovascular exclusion of aortoenteric fistula has been described as a bridge to definitive open repair surgery. However, little is known about transposing this technique to treat duodenocaval fistula. We report a case of a 20-year-old man who presented with a duodenocaval fistula arising from a metastatic nonseminomatous germ cell tumor. A staged technique using an initial endovenous exclusion of the fistula permitted stabilization of the patient and completion of his chemotherapy regimen. Subsequently, the stent graft was explanted with concomitant autogenous caval reconstruction, allowing the patient to be cancer free at 1-year follow-up.
