Endovascular Treatment of Peripheral Vascular Blowout Syndrome in End-Stage Malignancies

Background Vascular blowout syndrome (VBOS) is a life-threatening condition secondary to direct tumor encasement or invasion in advanced stage malignancies. Endovascular management can be used as an alternative to surgical treatment in this fragile patient population, providing a minimally invasive measure both acutely and prophylactically. Methods Three patients with peripheral VBOS secondary to advanced stage malignancies underwent successful endovascular treatment. Technical success was obtained in all patients with nonsignificant perioperative complications. Results Endovascular management controlled immediate life-threatening hemorrhage and enabled these high-risk patients to undergo other adjunctive therapeutic modalities. Conclusions Endovascular treatment can offer a safe and effective palliative measure of peripheral VBOS secondary to neoplastic erosion in patients with advanced stage malignancies.
