A case of multiple mycotic aneurysms of the abdominal aorta is presented. A 62-year-old woman was admitted to our hospital complaining of left abdominal and back pain with persistent high fever. Although the blood cultures were negative during medical treatment, the patient status seemed septic by laboratory findings such as WBC (14, 000/μl), CRP (20.2mg/dl), and ESR (100 mm/h). Abdominal CT and aortography showed two saccular aneurysms in the abdominal aorta, and these aneurysms were considered as mycotic ones because of their rapid growth and clinical features. An urgent operation was performed. The three aneurysmal orifices were identified in infrarenal abdominal aorta and these seemed to be pseudoaneurysms. Although tight inflammatory adhesions were found around the aneurysms, no active infection was detected. After removal of the thrombi and intimal wall with meticulous irrigation, the in situ graft replacement was carried out. All the bacterial cultures of thrombi and intimal wall of aneurysms were negative. The infection had subsided after operation and she remained well without recurrence one year after operation. A few cases of mycotic aneurysm of abdominal aorta have been reported in Japan, but cases with multiple mycotic aneurysms are rare. The mechanism of aneurysmal formation in the present case might be lodgement of circulating organisms within the aortic wall during preceding prolonged antibiotic chemotherapy. The early surgical treatment consisted of en bloc aneurysmectomy, in situ graft replacement, and adjuvant antibiotic chemotherapy might provide good results.

A 29-year-old female with aortic regurgitation associated with aortitis syndrome and severe stenosis of bilateral carotid arteries was reported. She had no symptom of brain ischemia, although an aortogram revealed complete occlusion of the left common carotid artery and the left subclavian artery, and severe stenosis of the right common carotid artery. The intracranial major arteries were perfused totally by the right vertebral artery via collaterals. The transcranial Doppler method and perfusion cintigraphy revealed normal cerebral perfusion. Therefore, we performed conventional aortic valve replacement without reconstruction of carotid arteries. During cardiopulmonary bypass, the mean systemic blood pressure was kept higher than 60mmHg under moderate-hypothermic (tympanic temperature: 25°C) pulsatile perfusion with monitoring of the left middle cerebral artery flow velocity. The patient did not develop any cerebral complications during or after the operation.

Four patients with multiple dissecting aortic aneurysms treated surgically from 1960 to 1996 were evaluated clinically. The incidence of multiple dissecting aortic aneurysms was 3.2% of all surgically treated cases of aortic dissection. Only one case suffered from Marfan's syndrome. Morphologically, all cases showed chronic DeBakey II+III type dissection. Case 1 was treated by Bentall's operation for DeBakey II type dissection and the residual aortic aneurysm was not treated surgically. Case 2 underwent a two-staged operation: Bentall's operation first, followed by entry closure with plication of the DeBakey III type aneurysm. Case 3 underwent a two-staged operation: graft replacement of the ascending aorta combined with coronary artery bypass grafting in the first operation and graft replacement of descending and abdominal aorta in the second. Case 4 was treated by graft replacement of the hemiarch, resuspension of the aortic valve and entry closure of the DeBakey III type dissection. Among them, two cases (Cases 1 and 2) whose aneurysms were treated incompletely showed a rapid growth and rupture of residual DeBakey III type aneurysm. In conclusion, one-staged aggressive and complete operation should be done for the patients with multiple dissecting aortic aneurysms. When a two-staged operation is selected, more intensive follow-up of the residual aortic aneurysm is needed.

We report a successfully treated case of infectious endocarditis with ventricular septal defect (VSD) and double-chambered right ventricle. A 41-year-old man complained of dyspnea. Echocardiography showed his tricuspid valve, aortic valve, and pulmonary valve had vegetation and severe regurgitation. He received treatment with antibiotics but it was not effective. He underwent TVR, AVR, pulmonary valve resection, VSD patch closure and RV abnormal muscle resection. Pathological findings of resected valves showed infectious endocarditis. He recovered uneventfully and resumed his original social activities.

Coronary artery bypass grafting (CABG) was performed in 16 patients with impaired left ventricular function due to ischemic heart disease (IHD) and the surgical procedures and cardiac functions before and after operation were studied. Preoperative angiogram showed three vessel disease in all patients. The ejection fraction was less than 40% in all and the mean cardiac index (CI) was 1.97l/min/m². At operation arterial graft was used in 10 patients (Group-AG) and no arterial graft but saphenous vein graft was used in 6 patients (Group-SVG). The average total cardiopulmonary bypass time, aortic cross clamping time and the number of revascularized vessels in both groups showed no significant differences. However, intraaortic balloon pumping was necessitated in one of Group-SVG and the requirement of postoperative catecholamine was in higher ratio in Group-SVG than in Group-AG. Postoperative CI improved to 3.1±0.4l/min/m² and 3.3±0.3 l/min/m² in Group-AG and Group-SVG, respectively. The postoperative New York Heart Association Functional Class improved to Class I or II in all patients and there were no significant differences of the improvement between the groups. Conclusively, it seems that the arterial grafts can be used safely and extensively in CABG for impaired left ventricular function due to IHD.

We have experienced 3 successful repair surgeries for insufficient bicuspid aortic valve. The operative procedure consisted of combinations of suture placation, raphe triangular resection, commisural annuloplasty, and patch closure of perforation due to infectious endocarditis. The postoperative course was uneventful and postoperative echocardiography showed residual regurgitation as only trivial or mild. Retrospective study done on 19 previous cases with insufficient bicuspid aortic valve demonstrated that this operative procedure could have been applied in 15 (79%) of the cases. These results showed that repair surgery for insufficient bicuspid aortic valve is useful and has a wide application.

Objective : To evaluate the reliability and the validity of the Japanese version of the Spinal Cord Independence Measure (SCIM) in patients with cervical spinal cord injury. Design : Cross-sectional, observational study. Setting : Rehabilitation ward for spinal cord injury in Japan. Patients and Methods : 26 inpatients with traumatic and non-traumatic cervical spinal cord injury, with an average age of 60.3, were included to examine the internal consistency of the subscales (subscores in each domain) and the whole scale, and to determine concurrent validity of the SCIM and the Functional Independence Measure (FIM) motor subscores. To examine interrater reliability, 12 of these patients were assessed by 2 physiatrists independently and intraclass correlation coefficients (ICC) for total scores and weighted kappas for individual item scores were calculated. Results : The ICC for total SCIM score was 0.99, and the weighted kappas for individual item scores showed moderate to strong agreement (kappa=0.54-1.00). The Cronbach's alpha coefficients for domain subscores and total score were above 0.71, demonstrating appropriate internal consistency of the SCIM. The total SCIM scores significantly correlated with the FIM motor subscores (Spearman's rho=0.95), however, there were some variations with the SCIM scores in patients who were rated as 6 (modified independence) with the FIM in such items as bladder management and indoor mobility. Conclusion : The results supported the internal consistency, interrater reliability and concurrent validity of the SCIM in patients with cervical spinal cord injury. The SCIM may be a potential measure to evaluate certain functional aspects that cannot be assessed by the FIM alone.

A 62-year-old woman was admitted to a regional hospital for acute myocardial infarction. Emergency coronary angiography revealed occlusion of the first diagonal branch, and transesophageal echocardiography showed severe mitral regurgitation due to anterior papillary muscle rupture. She was transferred to our hospital in a state of cardiogenic shock despite the use of high-dose catecholamine and intra-aortic balloon pumping. We immediately performed mitral valve replacement. The patient's postoperative course was uneventful and she was ambulatory when transferred to another hospital on foot on postoperative day 19. Physicians should be aware that fatal anterior papillary muscle rupture may be caused by isolated occlusion of the diagonal branch.

IABP is in wide clinical use as an effective adjunctive means for the management of seriously impaired cardiac function. Unfortunately, however, it is an undeniable fact that this specialized circulatory support technic has so far been used in severe heart disease cases in a desultory way, with no established criteria being available for indication of elective IABP for prophylactic purposes. Under such circumstances, it was felt worthwhile to analyze data on preoperative left ventricular function from a series of open heart surgery cases (25 treated with and 94 without IABP) encountered in our hospital since 1983 (when procedure for myocardial protection was virtually standardized) in an effort to formulate acceptable criteria for indication of elective IABP. Hemodynamic parameters studied were LVESVI, LVEF and LVEDP. The results led us to conclude that scheduled IABP can be regarded as indicated for use in each of the following valvular heart diseases if at least one of the respective criteria specified below is fulfilled: MR: LVESVI≥120ml/m², LVEF≤0.4, LVEDP≥21mmHg; AR: LVESVI≥135ml/m², LVEF≤0.4, LVEDP≥18mmHg; MS: LVESVI≥70ml/m², LVEF≤0.35, LVEDP≥23mmHg.

Thirty six patients with post-infarction complications underwent operation, and the postoperative and late follow-up results were analyzed. There were post-infarction ventricular septal perforation (VSP) in 9 patients and left ventricular aneurysm formation in 27 patients. The operative indications were poor physical work capacity in 13, cardiogenic shock or severe congestive heart failure in 10, left ventricular thrombus in 7, severe ventricular arrhythmia in 6, and repeated angina in 6. Left ventricular aneurysmectomy was performed in 14 patients and VSP closure was in 8. Coronary arteries were simultaneously bypassed in 14 patients. Three patients were died of sudden postoperative arrhythmia 10 days, 55 days and four years after operation. All survivors except two patients with preoperative massive cerebral infarction or prolonged heart failure were in New York Heart Association Class I or II in their late postoperative periods. However, five patients in whom the significant coronary lesion had not been bypassed or the bypassed grafts had occluded complained of mild angina after operation. Postoperative arrhythmia was one of major factors in the late results and simultaneous coronary artery bypass grafting was important to improve the symptoms in the late postoperative periods.
