A case of Gemella haemolysans bacterial thrombus triggered by early stage colon cancer and retrieved by mechanical thrombectomy

Abstract

The patient was a 67-year-old woman. She was admitted to our hospital for sudden onset of left hemiparalysis. Based on the diagnosis of right middle cerebral artery occlusion, we performed acute endovascular mechanical thrombectomy after injection of intravenous recombinant tissue plasminogen activator. White thrombus was recovered, and TICI grade was 3 in 1 pass. The postoperative neurological findings improved markedly, and the patient was discharged without any sequelae. Pathological examination of the embolus revealed Gram-positive cocci, and we suspected infective endocarditis and started antibiotic therapy, and performed upper and lower gastrointestinal endoscopy to find the source of Gemella haemolysans infection, which led to the discovery of early stage colorectal cancer, which was cured by endoscopic resection. In this case, we performed upper and lower gastrointestinal endoscopy to find the source of Gemella haemolysans infection.
