Endovascular coiling of right vertebral artery saccular aneurysm at non-branching site: A potential and safe treatment option

Abstract

We report the case of a woman in her 50 s who was admitted to the emergency room with a focal neurological deficit and thunderclap headache; computed tomography evidenced subarachnoid hemorrhage. An external ventricular drain (EVD) was placed before coiling a saccular aneurysm at the 4th segment of the right vertebral artery at the non-branching site, diagnosed with cerebral angiography. The patient's clinical conditions improved and she was discharged home with excellent functional status. Aneurysms of the non-branching vertebral artery are rare lesions associated with high morbidity and mortality. Endovascular treatment (EVT) has become an increasingly popular approach for these lesions as a potential and safe treatment option for ruptured VA saccular aneurysms, especially in the context of a patient with a poor initial neurological condition, diminishing the higher rates of morbidity and mortality linked to the complex technique of the surgical approach to the posterior fossa.
