[A Case Report of Endovascular Thrombectomy for Internal Carotid Artery Thromboembolism after Left Upper Lobectomy of Lung Cancer].

ABSTRACT

A 76-year-old man underwent a left upper lobectomy due to lung cancer. On postoperative day 3, he developed a cerebral infarction(NIHSS17). MR and right carotid angiography demonstrated a right internal carotid artery occlusion. The patient underwent an endovascular thrombectomy without intravenous administration of recombinant tissue plasminogen activator. Complete recanalization was achieved and the symptoms almost disappeared except for a slight dysarthria. The patient subsequently continued cancer treatment by administration of edoxaban. Reports of cerebral emboli due to a thrombus migrating from the stump of the pulmonary vein after a left upper lobectomy are increasing. Several reports indicate that left upper lobectomy carries a high risk of thromboembolism. The current prospective study demonstrates that a mechanical thrombectomy can significantly improve both neurological and cognitive functions of patients after acute ischemic stroke. Endovascular neurosurgeons should prepare for and await an opportunity for thrombectomy for patients undergoing pulmonary resection.
