Patients with fatty liver diagnosed by computed tomography (CT) were studied clinically. Diagnostic criteria of fatty liver by CT was that the ratio of CT value of the liver to that of the spleen was less than 0.90. In cases of fatty liver, hepatic volume was significantly more increased (p<0.01) than normal controls, but volume of the spleen was not more increased. Fatty liver was diagnosed by CT in thirty eight cases. These cases were divided into four groups according to causes of fatty liver.The first was obesity group (fifteen cases), the second was alcohol group (fourteen cases), the third was DM group (four cases) and the fourth was group of unknown origin (five cases). Values of GOT/GPT (OP ratio), γ-GTP, CHE, LAP and ALB were significantly different (p<0.01) between obesity and alcohol group. Many cases of obesity group showed hypercholinesterasemia, but in many cases of alcohol group values of cholinesterase were lower than normal range.

Liver function influenced by drinking were studied in cases of a thorough physical examination. Objects of our study were 172 cases who entered in our clinic during past two years. 172 cases were divided into three groups. 1st group was 70 cases who had drunk less than 20 grams of ethyl alcohol a day, 2nd group was 49 cases who had drunk 20 grams a day and 3rd group was 53 cases who had drunk 40 grams a day.
GOT, GOT/GPT, γ-GTP, CHE and LAP were changed significantly with the increase of drinking as a result of study of these three groups. Especially it was thought that GOT/GPT, γ-GTP and LAP reflected most sharply the grade of alcoholic liver injury.

We report a case of surgery for an infectious left subclavian artery aneurysm in a patient with metal allergy. The patient was a 41-year-old man allergic to iron, silver, manganese, and chromium. He had received a Nitinol stent in the left subclavian artery at a previous hospital. One stent had fallen out during implantation, and was put away in the terminal aorta. Ten days after the left subclavian implantation, the patient developed left shoulder pain and fever, which continued for 2 weeks. Contrastenhanced CT scan revealed a pseudoaneurysm of the left subclavian artery and abdominal aortitis. The patient underwent left subclavian artery aneurysmectomy, aorto-left subclavian artery bypass using the great saphenous vein, and removal of the stents in the left subclavian artery and abdominal aorta. The surgery was performed through a median sternotomy with cardiopulmonary support. A contrast-enhanced CT scan taken on the 12th postoperative day revealed a pseudoaneurysm of the abdominal aorta, and the patient underwent abdominal aortic artery replacement surgery on the 14th postoperative day. The patient was discharged from the hospital on the 27th day after the first surgery. The treatment of an aneurysm should be selected according to the patient’s background as well as anatomical factors.
