RESUMO
BACKGROUND: Transarterial chemoembolization (TACE) is a standard treatment for intermediate-stage hepatocellular carcinoma (HCC). The complications of TACE include biliary tract infection, liver dysfunction, tumor lysis syndrome, biloma, partial intestinal obstruction, cerebral lipiodol embolism, etc. There are few reports about tracheal fistula induced by TACE. CASE SUMMARY: A 42-year-old man came to our hospital with cough and expectoration for 1 month after TACE for HCC. Laboratory test results showed abnormalities of albumin, hemoglobin, prothrombin time, C-reactive protein, D-dimer, and prothrombin. Culture of both phlegm and liver pus revealed growth of Citrobacter flavescens. Computed tomography showed infection in the inferior lobe of the right lung and a low-density lesion with gas in the right liver. Liver ultrasound showed that there was a big hypoechoic liquid lesion without blood flow signal. Drainage for liver abscess by needle puncture under ultrasonic guidance was performed. After 1 month of drainage and anti-infection therapy, the abscess in the liver and the infection in the lung were reduced obviously, and the symptom of expectoration was relieved. CONCLUSION: Clinicians should be alert to the possibility of complications of liver abscess and tracheal fistula after TACE for HCC. Drainage for liver abscess by needle puncture under ultrasonic guidance could relieve the liver abscess and tracheal fistula.
