Small bowel ileus due to the parasitic infection caused by omophagia of freshwater fish is relatively rare. We present a case of small bowel ileus possibly caused by inflammatory change associated with Gnathostoma doloresi infection. A 62-year-old man underwent partial resection of the small bowel under a diagnosis of ileus due to complete obstruction of the small bowel. He had eaten a few slices of raw freshwater fish four weeks before abdominal pain appeared, and he contracted creeping disease with several welts on the abdominal wall. Chronic inflammatory change suggestive of parasite infection was observed in the resected specimen. An immunoserodiagnostic study using microenzyme-linked immunosorbent assay led to a diagnosis of Gnathostoma doloresi infection. The postoperative course was favorable, and the patient was discharged 12 days after surgery. Only two cases of ileus due to Gnathostoma doloresi infection have ever been reported.

We describe two cases with pulmonary atresia, intact ventricular septum (PA/IVS), and right ventricle-dependent coronary circulation, who suffered from myocardial ischemic symptoms. Case 1 : A female infant diagnosed with PA/IVS during the fetal period was born after 40 weeks of gestation, weighing 3,078 g. Aortography demonstrated that the right coronary artery (RCA) was interrupted at the proximal segment, and the left coronary artery (LCA) did not show any stenosis. Right ventriculogram revealed sinusoidal connections filling the distal part of the right coronary artery and fistulous communications to the left anterior descending artery. Temporary ST segmental depression in ECG during milk feeding or crying improved spontaneously with time. Bidirectional Glenn shunt (BDG) was performed at 3 months old, and she underwent Fontan repair at 4 years old. She is doing well with no evidence of myocardial ischemic change. Case 2 : A female infant was born after 39 weeks of gestation, weighing 3,062 g. Aortography demonstrated that the RCA was interrupted at the middle segment, and the distal area depended on the right ventricle. LCA ostium at the ascending aorta was absent. Multiple sinusoidal connections were seen in the right ventricular myocardium with filling of the LCAs but no reflux into the aortic sinuses. After ventricular tachycardia occurred at 2 months old, left ventricular function deteriorated. BDG with ligation of the arterial duct was performed at age 3 months. The arterial blood pressure was 76/53 (62) mmHg and pressure in SVC was 21 mmHg immediately after the operation. However, arterial oxygen saturation, right atrium venous oxygen saturation and left ventricular ejection fraction were 50%, 16%, and 10%, respectively. Although extracorporeal membrane oxygenation was established for circulatory and myocardial oxygenation support on the postoperative day 2, her left ventricular function did not recover and she died on postoperative day 5. It is difficult to rescue such a case in which almost all coronary circulation depends on the right ventricle filled with desaturated blood.

Multivessel coronary artery bypass grafting (CABG) utilizing ITA grafts was performed in 110 consecutive patients, ranging in age from 24 to 76 years with a mean of 54±9 years. A mean of 3.2±0.8 grafts per patient was placed with a hospital mortality of 0.9%. Bilateral ITAs (BITA) were used in 87 patients and sequential ITA grafting (SQ-ITA) was carried out in 31, and both BITA and SQ-ITA were used in 8 patients. Noncardiac late death occurred in 1 patient and a 5-year survival rate was 98%. During this follow-up term, 11 (10%) patients underwent low-risk PTCA for ITA anastomotic stenosis (4 lesions), SVG stenosis (5 lesions) and native coronary stenosis (4 lesions) with a success in all. No reoperation has been required so far in this series. Graft patency rates were 97% for BITA with no differences for the left and right ITAs, and 100% for SQ-ITA (both proximal and distal). No sternal infection was encountered in this series, on which we believe mediastinal, sternal and subcutaneous irrigation appeared most effective. In BITA grafting, right ITA was frequently anastomosed to the LAD, passing on the aorta, which will make reoperation through a median sternotomy dangerous to this graft. To improve safety for reoperation, we have covered the ITA graft with an 8mm EPTFE graft or membrane with no side effects on ITA grafts. However, true efficacy of this protective method remains unproved because no reoperations have been required in this series of patients.

We studied the incidence of associated ischemic heart disease (IHD) among 110 consecutive patients (males 99, females 11, mean age 66.0±8.8 years) operated upon for arteriosclerosis obliterans (ASO). The screening of IHD was routinely conducted by using dipyridamole thallium scintigraphy, and when results were positive, the lesion was further confirmed by selective coronary angiography. More than 50% luminal stenosis of the major coronary arteries was judged as positive for IHD. Forty-eight patients (44%) of ASO were simultaneously afflicted with IHD. Ten patients were operated on for ASO after coronary artery bypass grafting (CABG), five for ASO and IHD (CABG) simultaneously, eight for ASO after PTCA. Twenty-five patients underwent surgery for ASO only with infusion of nitroglycerin, with or without diltiazem. We also compared 15 patients with thrombotic obliteration at the end of the abdominal aorta o: Leriche's syndrome with the remaining 95 patients in this series. The patients with Leriche's syndrome were younger and had higher incidences of hyperlipidemia (p=0.0254) and IHD (p=0.0225) than those without Leriche's syndrome. In surgical treatment for ASO, particularly for Leriche's syndrome, meticulous attention to complications is needed due to the frequent association of IHD. When both ASO and IHD are severe enough to warrant surgical treatment at the earliest opportunity, we recommend concomitant operations for ASO and IHD (CABG).

We report a successful staged repair of anomalous origin of right pulmonary artery from the ascending aorta in a neonate. A two-day-old girl, who suffered from severe circulatory failure, was admitted. In spite of all medical treatment, acidosis and systemic hypotension developed. Right pulmonary artery banding was performed in an emergency procedure, resulting in immediate elevation of systemic blood pressure. Definitive operation was subsequently performed on the 48th day after birth. The right pulmonary artery, which was de-banded and divided from aorta, was anastomosed directly to the pulmonary trunk in a side-to-end manner. The postoperative course was uneventful and the pulmonary artery pressure was within the normal range.

A 49-year-old man who had had severe tripple vessel coronary disease and low left ventricular function (EF=29%) underwent coronary artery bypass grafting. Following the procedure he could not be weaned from cardiopulmonary bypass (CPB) even with an intra-aortic balloon pumping (IABP). Left ventricular assist using a centrifugal pump (CFP) together with IABP was then utilized with a dramatic recovery from profound postcardiotomy cardiogenic shock, and the CPB was successfully terminated. The left ventricular function recovered gradually from intraoperative myocardial damage. The CFP was successfully removed at 86 LHB hour and the IABP at 9th postoperative day. At present 12 months after LHB, he reveals no angina. Settting up the left ventricular support using a CFP is simple and not-time-consuming, so this system with IABP is of practical use in the case of unpredicted postcardiotomy cardiogenic shock.
