RESUMO
Buerger's disease (Thromboangiitis obliterans--TAO) is a nonatherosclerotic, segmental inflammatory disease that most frequently affects the small and medium-sized arteries and veins in the upper and lower extremities. There exists an extremely strong association between heavy tobacco use and TAO. The histopathology of the involved blood vessels varies according to the chronologic stage of the disease at which the tissue sample is obtained for examination. The histopathology is most likely to be diagnostic at the acute phase of the disease. Buerger's disease typically occurs in young male smokers, with the onset of symptoms before the age of 40 to 45 years. Several published series have shown an increasing prevalence of the disease in women. There is little information on the use of intra-arterial thrombolytic therapy, prostaglandin therapy, or angiogenesis. Discontinuation of tobacco use is the mainstay of treatment. Patients who successfully stop smoking almost never need amputation.

Pyogenic liver abscesses are caused by appendicitis in less than 10%. Also the ascending septic inflammation of portal vein (pylephlebitis) could be a serious complication of intra-abdominal infection. Although pylephlebitis is not frequent today, its' mortality and morbidity rates remain high. We describe a case of young man with fever, abdominal pain, and multiple hepatic abscesses. After the symptomatic relief due to antibiotic therapy the pain returned as a result of the development of portal and mesenteric vein thrombosis. The cause of either hepatic abscesses or thrombosis was not clear at the time of dismissal. 2 months later the patient underwent acute abdominal revision with appendectomy for acute phlegmonous and gangrenous appendicitis. Since that time he has been without any clinical symptoms.
