Splenic infarction after left upper lobectomy: a report of a case.

We report the case of a 70-year-old man who developed a splenic infarction due to a thrombus in the pulmonary vein (PV) stump after left upper lobectomy (LUL). Preoperative imaging showed a mass measuring > 5 cm in the upper lobe of the left lung, and sputum cytology revealed squamous cell carcinoma. Therefore, video-assisted thoracoscopic LUL was performed. The postoperative course was uneventful but biochemical blood tests showed an increased inflammatory response. Contrast-enhanced computed tomography revealed splenic infarction and a thrombus in the left superior PV stump. Prompt treatment with anticoagulants was administered, and the patient was discharged with mild recovery. However, the patient developed cerebral infarction after discharge and died 33 days after the surgery. Splenic infarction is a rare postoperative complication, with only three reported cases, including this report. However, this condition should be considered along with PV thrombus when evaluating an increased inflammatory response after LUL. [ABSTRACT FROM AUTHOR]
