A case report: Ruptured aneurysm with a wide neck treated by flow diverter stent and coil embolization.

ABSTRACT

Diagnosis and endovascular treatment for ruptured wide neck aneurysms are challenges in clinics, particularly in developing countries. In the present study, we described a clinical case with a ruptured wide neck aneurysm in Vietnam treated by flow diverter stent and coil embolization. A 77-year-old- female patient had a right droopy eyelid for 2 months. The patient was admitted to hospital on the second day after being presented with a sudden-severe headache. Cerebral computed tomography (CT) and magnetic resonance imaging (MRI) were taken on the second day and fifth day after the onset of the headache. The results showed an aneurysm in the right internal carotid artery but no potential subarachnoid hemorrhage (SAH) was displayed. An uncoagulated blood was found in cerebrospinal fluid indicated by a lumbar puncture test. Digital subtraction angiography provided images with one wide-neck right internal carotid aneurysm. The patient was treated by flow diverter stent and coil embolization and the dual antiplatelet therapy with ticagrelor and aspirin at home. After 45 days, the patient did not face with any complication, no neurological symptoms, and the aneurysm was partially thrombosed indicated by MRI images. These results suggested that a lumbar puncture should be analyzed on the patient with brain aneurysm appeared a sudden severe headache and even no potential SAH on brain MRI or CT was found. The combination of flow diverter stent and coil embolization to treat cases with ruptured wide necked aneurysms should be considered in the future.
