Cyanoacrylate embolization of the lingual artery for oropharyngeal hemorrhage in head and neck cancer: a dedicated cohort study
This single-center retrospective cohort study demonstrates that cyanoacrylate glue embolization of the lingual artery is a safe and effective first-line treatment for achieving primary hemostasis in patients with oropharyngeal hemorrhage caused by head and neck squamous cell carcinoma, with no procedure-related complications and a low rate of rebleeding from the embolized vessel.

When cancer spreads deeply into the mouth and throat, it can erode the delicate blood vessels that feed the tongue and surrounding tissues. In these advanced stages, a sudden, massive bleed from the tongue can be a terrifying and life-threatening emergency. The blood can flood the airway, causing suffocation, or lead to a rapid loss of blood pressure that the body cannot recover from. Traditionally, surgeons might try to tie off the bleeding vessel, but the tissue in these patients is often so damaged by previous treatments that surgery is incredibly difficult and risky. In recent years, doctors have turned to a less invasive approach called embolization. This procedure involves threading a tiny tube through the arteries from the groin up to the neck, where doctors can inject a substance to block the bleeding vessel from the inside. One such substance is a special medical glue that hardens almost instantly when it touches blood, sealing the vessel shut.
A team of researchers at a university hospital in Dijon, France, set out to see how well this specific glue works for blocking the lingual artery, the main blood supply to the tongue, in patients with head and neck cancer. They looked back at the records of twenty-two patients who had received this treatment between 2010 and 2025. Every single one of these patients had a severe bleed related to their cancer, and every one of them was treated with the same type of cyanoacrylate glue, mixed with an oily contrast agent to make it visible on X-ray screens. The doctors wanted to know if the glue could stop the bleeding effectively without causing damage to the tongue itself, such as tissue death, which is a known risk if the glue travels too far or blocks too much blood flow.
The results of their review were strikingly positive. In every single procedure performed, the doctors successfully blocked the bleeding vessel, and the bleeding stopped immediately. There were no instances where the glue accidentally blocked a healthy vessel nearby, and critically, no patient suffered from tissue death or necrosis of the tongue as a direct result of the glue injection. The tongue remained viable and healthy in all cases. While some patients did experience bleeding again later from a different source, the specific artery that had been glued remained sealed. Only one patient had a recurrence of bleeding from the treated artery itself, and even that was managed successfully with further treatment.
The study also tracked the overall survival of the patients. Thirty days after the procedure, four patients had passed away, but only one of those deaths was directly caused by the bleeding. The other three deaths were due to the progression of their underlying cancer or other complications common in very sick patients. This distinction is important because it shows that while the procedure could not cure the cancer, it successfully solved the immediate, life-threatening problem of the hemorrhage. The researchers noted that the glue's ability to harden instantly and permanently, regardless of the patient's blood clotting ability, made it particularly useful for these fragile patients who often have poor blood chemistry.
The authors concluded that using this medical glue to block the lingual artery is a safe and highly effective way to stop severe bleeding in the mouth and throat for cancer patients. They found that the fear of the glue causing tongue damage did not materialize in their group, provided the doctors used careful technique and precise imaging to guide the injection. This approach offers a reliable, minimally invasive option for controlling a dangerous symptom, giving patients a chance to survive the immediate crisis. The study suggests that this method should be considered a primary choice for doctors facing this specific emergency, though the researchers noted that larger, future studies would be needed to confirm these findings across different hospitals and to refine the standard ways of performing the procedure.
