Management of acute ischemic stroke after pulmonary resection: incidence and efficacy of endovascular thrombus aspiration.

Objective: We analyzed acute ischemic stroke by thromboembolism in the early period after lung cancer surgery.

Methods: A retrospective review of the clinical records of patients who underwent lung resection for primary lung cancer was performed. Patients who underwent lobectomy, bilobectomy, and pneumonectomy were included. The clinical characteristics of the patients, the incidence of atrial fibrillation (Af) after surgery, and the incidence of acute ischemic stroke were analyzed. The clinical courses of patients having acute ischemic stroke were also reviewed.

Results: In 4 (0.6%) of 696 patients, acute ischemic stroke occurred in the early period during hospitalization after lung cancer surgery. Acute ischemic stroke occurred within 4 days in three cases and after 4 days in one case. The resection site of the lung was the left side in all cases, and there were three cases of left upper lobectomy and one case of left lower lobectomy. As for the two recent patients, thrombus removal was performed by a neurosurgeon, and both cases achieved successful recanalization. The time between symptom detection and recanalization was 205 and 170 min, respectively. One patient was cured without any residual effect of disease, and the other patient's hemiplegia resolved and aphasia improved.

Conclusion: Since cerebral infarction impairs the patient's quality of life, thrombus removal should be considered if possible.
