Prophylactic Greenfield filters in high-risk trauma patients are safe and durable. There appears to be no significant consequence in over 5 years of follow-up.

The management of patients with head and neck cancer can be complicated by massive carotid artery hemorrhage, often requiring ligation owing to the emergent conditions and scarring from previous surgery and radiation. A case of emergent endovascular management of carotid artery hemorrhage in a patient treated for pharyngeal carcinoma is described. Hemorrhage was controlled, but on follow-up the patient developed a carotid-cutaneous fistula with exposure of the coils. Further management required the use of autogenous vein to replace the involved vessels. This case demonstrates that endovascular control of carotid hemorrhage can be successful, but close follow-up is necessary to identify potential subsequent complications.
