Summary
Brief summary (as posted)
This phase I trial tests whether embolization done prior to surgery (preoperative) will improve surgical outcomes in head and neck tumors with large amounts of blood vessels (hypervascular). Embolization is a minimally invasive surgical technique performed under angiographic (imaging of blood vessels) guidance. Embolization therapy injects tiny particles into the arteries feeding tumors to cut off their blood supply which may help improve outcomes by preventing blood loss during surgery, reducing surgical times, and shrinking tumors or reducing recurrence.

- EXPERIMENTAL
- label
- Treatment (PVA, EOV, tumor vessel embolization)
- description
- Patients receive iodixanol via injection and undergo diagnostic cerebral angiogram over 30 minutes. If the tumor blood supply is suitable, patients undergo tumor vessel embolization with PVA suspended in EOV and delivered via a catheter. Patients also undergo head and neck CT scans immediately after completion of tumor vessel embolization, and again between 2-3 months later.
