Investigation of Usefulness of the Embolization Method for Tumor Hemorrhage in the Head and Neck Causing Formation of a Pseudoaneurysm in a Blood Vessel Feeding the Central Nervous System
We performed endovascular treatment on four cases of head and neck malignant tumor in which a pseudoaneurysm had formed in a blood vessel feeding the central nervous system and had caused intractable arterial hemorrhage. The procedure was successfully performed in all of the patients, and hemostasis was achieved. Postoperative systolic blood pressure increased by 40.5 mmHg on average, and all of the patients recovered from hypovolemic shock, including cardiac arrest. This method is more useful than other current methods if the operators have sufficient knowledge and experience, and judge emergency cases calmly and accurately, It may become the first choice for most cases of tumor hemorrhage in the head and neck in the future.
