Abstract:
Sepsis and liver abscess are serious complications following transarterial embolization (TAE) for hepatocellular carcinoma (HCC). However, the exact incidence and the necessity of antibiotic prophylaxis remain undetermined. Between November 1996 and November 1997, we prospectively studied bacterial infections in 231 HCC patients who underwent 287 angiographic procedures without antibiotic prophylaxis, including 176 TAEs and 111 hepatic arteriographies (HAs). Four of the 111 HAs were complicated by transient asymptomatic bacteremia. Of the 176 TAEs, 2 were associated with asymptomatic bacteremia, and 7 (4%) were associated with symptomatic bacterial infection, including 3 cases of sepsis, 2 of liver abscess, and 2 of infected biloma. For patients with HCC, TAE was associated with a higher risk of developing symptomatic bacterial infections than was HA (4% vs. 0, respectively; P = .03). Previous gastrectomy was the only possible risk factor for liver abscess. Finally, early diagnosis and treatment of these infectious complications usually result in successful outcome.
