Endovascular Management of External Iliac Blowout Syndrome Secondary to Recurrent Sigmoid Cancer

Blowout syndrome caused by vascular invasion is a dreadful complication of late stage malignancies that carry high morbidity and poor overall prognosis in a compromised population. Endovascular management can offer minimally invasive and life-saving alternative for such acute conditions. We describe the case of a 62-year-old man with massive fresh bleeding per rectum and shock resulting from rupture of the left external iliac artery secondary to nearby infiltrative recurrent sigmoid cancer. This complication is rare, presents dramatically, and is frequently fatal. The patient was successfully treated with a stent graft deployment in order to achieve hemostasis and reinstituting the arterial integrity.
