- Abstract: Among the less reported complications after thoracic endovascular aortic repair (TEVAR) is type II endoleak (T2EL). The intercostal and bronchial artery are known as feeder vessels to T2EL after TEVAR. We experienced two cases of successful treatment of percutaneous transarterial feeder vessels embolization via right costocervical trunk approach for patients with persistent T2EL and sac enlargement of an arch aneurysm after TEVAR. The costocervical trunk route is possible for key vessels to construct a collateral pathway to feeder vessels of the endoleak nidus of T2EL after TEVAR procedures for aortic arch aneurysm. A preembolizational Catheter-Directed CT angiogram (CTA) can be helpful to prevent harmful complications (e.g., spinal cord infarction).
