A 73-year-old man complained of sudden severe back pain and was admitted to a community hospital on February 2, 1994. DeBakey IIIb aortic dissection was diagnosed and he was treated conservatively. He noted a pulsating mass in his abdomen on June 7, 1995 and was referred to our hospital. Because of a decrease in platelet and fibrinogen and increase in FDP, local disseminated intravascular coagulation was diagnosed. Since abdominal pain continued, impending rupture was suspected. Computed tomogram showed abdominal aortic dissection and multiple iliac aneurysms. As coagulopathy did not improved by medical treatment, we performed prosthetic graft replacement of the aortio-iliac system on September 4, 1995. Before operation, the effectiveness of heparin was confirmed. After the operation local disseminated intravascular coagulation improved without drug therapy.

We evaluated long-term survival and morbidity of 191 patients (161 non-ruptured and 30 ruptured) undergoing abdominal aortic aneurysm repair between 1980 and 1997. Thirty-day mortality rates of non-ruptured and ruptured aneurysms were 1.2% and 36.6%, respectively. Hospital death occurred in 3.1% of patients with non-ruptured aneurysms and 53.3% of those with ruptured aneurysms. Cumulative survival rates after successful AAA repair at 5 and 10 years were 76.3% and 42.3%, respectively. These were lower than survival rates in the age- and gender-matched general population. The most frequent cause of late death was cardiac problems (28.8%) including myocardial infarction. Other causes included stroke (19.2%), malignant neoplasm (17.3%), and ruptured recurrent aneurysms at or above the proximal anastomosis (9.6%) including aorto-enteric fistulas. Regarding late vascular complications, recurrent aneurysms at or above the proximal anastomosis were found in 10% of patients, including 3.5% of true aneurysms, 4.7% of anastomotic aneurysms, and 1.8% of aorto-enteric fistulas. Thoracic aortic aneurysms were found in 3.7% and aortic dissection in 4.2%. Cumulative graft patency rates at 10 and 15 years were 97.4% and 90.9%, respectively. Suppressive treatment for arteriosclerosis and continuous careful follow-up with an aggressive diagnostic approach may reduce morbidity and mortality from recurrent aneurysms or coronary artery disease, thereby improving late survival after AAA surgery.

　　We describe a case of Inose-type hepatic encephalopathy due to congenital gastro-renal shunt that was effectively treated with balloon-occluded retrograde transvenous obliteration (B-RTO). An 80-year-old woman repeatedly experienced syncope. Her plasma concentration of NH₃ was elevated to 2363 level and syncope attacks improved after the gastro-renal shunt was closed by B-RTO. Although a congenital gastro-renal shunt is usually treated by surgical ligation, B-RTO is can be effective and less invasive treatment for such cases.

Infants with complete atrioventricular canal (CAVC) and severe congestive heart failure, not responding to medical managements, presents a difficult management problem. Between December, 1980, and August, 1987, 16 infants with CAVC presenting severe congestive heart failure underwent pulmonary artery banding. Average age at operation was 1.7 months (0.5 to 4) and average weight was 3.5kg (2.5∼4.9). Only four patients were older than 3 months of age at operation. Pre-operative cardiac catheterization and echocardiogram demonstrated that seven patients had mild to severe left atrioventricular valve regurgitation. Hospital death occurred in one patient (6%) due to rupture of the pulmonary artery. Of three late deaths, one patient had congestive heart failure, and one patient complicated with partial obstruction of right pulmonary artery died suddenly of an upper respiratory infection 11 months after rebanding. Survivors have been followed 18 to 94 months and all patients are growing at an increased rate postoperatively. In five patients of 12 long-term survivors who have undergone cardiac catheterization 37 to 83 months after the operation, pulmonary/systemic systolic pressure ratio (PP/PS) were 0.2∼0.42 (average 0.28). It is concluded that the pulmonary artery banding in infants with CAVC can be performed with low operative and late mortality and can provide good relief of symptoms and allow normal growth and development. It should be emphasized that early surgical palliation is mandatory to prevent the development of pulmonary hypertension and pulmonary emphysematous change.

Enteral feeding is generally accepted in patients who cannot take nutrients orally. Percutaneous endoscopic gastrostomy (PEG) is a major enteral means for the introduction of nutritional solutions. However, jejunal feeding is sometimes employed instead of gastric feeding in cases of post-gastrectomy or repeated aspiration after PEG. The digestion and absorption of nutrients in trans-jejunal feeding might be different from those in trans-gastric feeding. In the present study, we measured the serum concentations of micronutrients and vitamins in the cases of direct percutaneous endoscopic jejunostomy (D-PEJ), compared to those of PEG. The enteral feeding has been continued for more than six months in all the cases. Serum copper and zinc concentration were significantly decreased in the D-PEJ group, whereas no significant difference in the concentrations of iron, selenium, vitamins A, B12 and E was ovserved between the two groups. Anemia and neutropenia were frequently observed in many patients with D-PEJ. These conditions were associated with copper deficiency. Much attention should be paid to copper and zinc deficiency in long-term trans-jejunal feeding.

In recent years, plain X-ray CT has often been the first choice for imaging examination of acute abdomen in emergency medical settings. Ultrasound examination depends on the skill of the operator and the findings are subjective. However, we often experience cases in which more information can be obtained by abdominal ultrasonography than by plain CT. In this report, we describe two cases in which ultrasonography and plain CT imaging were performed in patients with right lower abdominal pain due to suspected abscess formation around the cecum. In the future, policies to reduce medical costs such as community healthcare initiatives may progress, and the number of facilities with high-priced medical equipment such as X-ray CT may decrease. Ultrasonography provides more information than simple CT examination, so we believe that ultrasonography should be the first choice for diagnostic imaging of acute abdomen. Therefore, it is important for those involved in ultrasonography to continuously acquire knowledge and scanning techniques.
