A case of thrombus retrieval using an inner catheter as an intermediate catheter

Thrombus retrieval therapy for acute main artery occlusion has become the standard of care and is widely used, but there are some cases that are difficult to treat. In this case, we used a diagnostic catheter as an intermediate catheter and continued the trans–femoral approach to a case in which a conventional guiding catheter with a balloon could not reach the internal carotid artery. This method may be useful for patients who are difficult to approach.
