Endovascular treatment of a traumatic carotid pseudoaneurysm with the Tubridge stent; A case report / 中国脑血管病杂志

ABSTRACT

Traumatic intracranial pseudoaneurysm is usually caused by blunt or penetrating head injuries. It lacks of real blood vessel wall and is covered only by a fragile connective tissue layer. Traumatic intracranial pseudoaneurysm mainly occurs in the carotid, cavernous and petrous segments of the internal carotid artery. A case of traumatic internal carotid artery pseudoaneurysm successfully treated with Tubridge flow diverter device was reported. The 32-year-old male patient was diagnosed as a pseudoaneurysm of the left internal carotid artery after a traffic accident, and received treatment with Tubridge flow diverter device one month later. After stents release, angiography showed obviously retained contrast agent in pseudoaneurysm, decreased aneurysm size and well-opened stents. The size of the pseudoaneurysm was found reduced by magnetic resonance angiography reexamination on the 4th day after the operation,and a further decrease on the 10th day by digital subtraction angiography (DSA) reexamination. Four months after the operation, DSA showed the aneurysm was completely cured.
