A 42-year-old male was admitted to Tokyo University Hospital because of confusion, aphasia and right hemiparesis. Cranial computed tomography and cerebral angiography demonstrated cerebral infarction due to occlusion of the left middle cerebral artery, while chest roentgenography disclosed a nodular shadow in the right upper lobe and swelling of right hilar and paratracheal lymph nodes. These findings suggested carcinoma of pulmonary origin and tumor-associated cerebral thrombosis, but a possibility of gastric cancer was raised by the finding of cervical lymph node biopsy which revealed signet ring cells in metastatic adenocarcinoma. He developed disseminated intravascular coagulation syndrome and died on the 83rd hospital day. Autopsy revealed adenocarcinoma of the lung with signet ring cells and non-bacterial thrombotic endocarditis which appeared to be responsible for the cerebral infarction. The relationship between adenocarcinoma of the lung with signet ring cells and non-bacterial thrombotic endocarditis was discussed.

A retrospective examination was made of eleven patients that developed prosthetic valve endocarditis (PVE) during the period from January 1960 to December 1987. Infection occurred in one patient within 60 days after surgery and in 10 thereafter. Causative organism was found in 6 patients. As organism, Staphylococcus species were noted in 4 patients and Peptstreptococcus was noted in one patient and Aspergyllus was noted in one patient. Three of eleven patients received medical treatment only and the other 8 patients were received surgical treatment. Mortality rate was 67% in medical group and 29% in surgical group. Two patients with medical treatment died of cerebral infarction about 40 days after the onset of PVE. In surgical group one patient died of uncontrollable Aspergillus infection and the other one died of dyspnea. No survivors who was treated surgically have developed reinfection or relapse of infection but four of them developed perivalvular leakage and needed reoperation. Absolute removal and closure of the valve ring abscess and reconstruction of defect should be considered for those needed surgical treatment to prevent reinfection and relapse developing.

By studying 3,408 consecutive autopsied elderly patients, we found that two thirds of the 132 massive cerebral infarctions (86) were embolic, of cardiac origin. Embolic infarction associated with nonvalvular atrial fibrillation was seen in 48 cases (36%), half due to the first stroke. Embolic infarction associated with heart disease other than nonvalvular atrial fibrillation was seen in 23 cases (17%), and that from nonbacterial thrombotic endocarditis was seen in 15 cases (11%). Thrombotic infarction or infarction of nonembolic cardiac origin was found in only 39 cases (30%). Of 56 patients with fatal massive cerebral infarction who died less than or equal to 2 weeks after their stroke, 25 (45%) had embolic strokes associated with nonvalvular atrial fibrillation. Our study shows that nonvalvular atrial fibrillation is a very important cause of fatal massive cerebral infarction in the elderly.

The occurrence of central nervous system (CNS) complications was studied retrospectively in 150 patients with bacteremia caused by Staphylococcus aureus, Streptococcus pneumoniae, beta-hemolytic streptococci or Escherichia coli. The incidence and clinical manifestations of different CNS complications were noted during 1 month after the bacteremia. Special attention was paid to vascular complications (infarction or hemorrhage), infections (meningitis or brain abscess) and mental changes when they were the only signs of CNS origin (lowered level of consciousness, confusion or delirium). The risk of cerebral infarction was elevated in the patients with bacteremia during the first month after the positive blood culture as compared with the overall risk of stroke in the general population. 10/150 patients (7%) developed cerebral infarction during that month. Two of these cases were associated with bacterial meningitis and 1 with endocarditis. Mental changes as a main symptom of CNS origin occurred in 27% of patients with bacteremia. Increasing patient age predisposed to this complication. Mental changes were not associated with any bacterial species studied. Altogether 40% of the patients developed CNS complications, which were a significant risk factor for death during the first month after the bacteremia.

Twenty patients with active infective endocarditis, 11 with native valve endocarditis (NVE) and 9 with prosthetic valve endocarditis (PVE), were treated surgically from 1975 through April 1987 at Kyushu University Hospital. The operative indications were congestive heart failure mainly due to massive aortic regurgitation in 18, periannular abscess in 6, major embolism in 5 and severe hemolysis in 3 patients. In the group of NVE, single aortic valve replacement was performed in 4 patients and multiple valve replacement in the remainder. One patient died early postoperatively from LOS. Two patients with recurrent infective endocarditis, which occurred within 60 days after previous prosthetic valve replacement, were operated subsequently as early PVE. All other patients became NYHA class I postoperatively except for one patient who died from thrombosed valve. In the group PVE, re-AVR was done in 3, re-MVR in five, double valve replacement in two and re-fixation of the prosthesis to the aortic annulus in one patient. Two patients with early PVE died from recurrent endocarditis late postoperatively. One of 7 patients with late PVE, who had suffered from myocardial and cerebral infarction before reoperation, died from multiple organ failure. There were 3 patients with perivalvular leakage due to late active PVE, whose preoperative signs of inflammation were negative or minimum. As recurrent perivalvular leakage due to persistent infective endocarditis might frequently occur in such cases, complete resection and debridement of infected foci should be emphasized.

A 40-year-old woman was admitted to our hospital because of left hemiplegia. She was affected with myocardial infarction and cerebral infarction. Echocardiogram revealed that the aortic and mitral valves had thick and uneven echoes suggesting vegetations. Judging from the finding that repeated blood cultures were negative, we had considered in her lifetime that myocardial and cerebral infarctions were due to embolization associated with nonbacterial thrombotic endocarditis (NBTE). At autopsy, histological diagnosis was made as ovarian cancer with disseminated intravascular coagulation. From the clinical course and the histological findings, we diagnosed this patient as NBTE.

The case of a child with a severe immunodeficiency (purine-nucleoside-phosphorylase deficit) in whom an allogenic bone marrow transplant was performed is reported. CT scan showed image suggestive of cerebral infarction. Clinical course and hemostasis alterations suggest a non-bacterial thrombotic endocarditis. Neurologic complications in bone marrow transplant are review.

Cerebral infarcts in 3 patients revealed the presence of disseminated intravascular coagulation (DIVC) of cancerous origin before any clinical manifestations of the neoplasm. Neurologic manifestations of these consumption coagulopathies almost constantly produce a picture of diffuse encephalopathy, expression of disseminated microinfarcts; however, transient or constituted focalized ischemic accidents by occlusion of a medium sized artery are also possible, and this in the absence of non-bacterial thrombotic endocarditis. Biologic diagnosis of DIVC is not always simple, and screening tests (platelet count, prothrombin and fibrinogen levels) can remain within normal limits during chronic forms, as a result of a subjacent inflammatory syndrome, frequently associated with cancer. Two other specific serum tests are therefore of fundamental interest: assay of fibrin degradation products and tests for soluble complexes.

The clinical and pathologic findings in 42 autopsy proved cases of cerebral infarction from cancer-associated non-bacterial thrombotic endocarditis were reviewed. Carcinoma of the lung was the most common malignancy. Most patients had disseminated cancer, but in six patients, the condition was stable or in remission, and six patients had localized cancer; two patients were not known to have cancer until neurologic symptoms developed. Neurologic symptoms were focal, suggesting stroke in 18; diffuse, suggesting metabolic encephalopathy in nine; and mixed in five. Neurologic signs were often the only evidence of thromboembolism. The definitive diagnostic test was cerebral angiography showing multiple arterial occlusions. Anticoagulation with heparin appeared to help some patients and did not promote brain hemorrhage. Early diagnosis and vigorous treatment of non-bacterial endocarditis may prevent severe neurologic disability.

In a retrospective study the reports of 211 cases of cardiogenic cerebral embolism--diagnosed on the base of neurological and cardiological findings--were analyzed in view of signs and findings of prognostic value. There were 21 patients with TIA, 39 cases of RIND and 151 patients with cerebral infarction, 60 of which showed mild and 91 severe neurological symptoms. 38 patients died during the period of hospitalization. While sex of the patients as well as vascular risk factors (hypertension, diabetes mellitus, cigarette smoking) did not influence the clinical course of the disease, patients with TIA or RIND in general were younger (about 5 years) than those with severe stroke. Prognosis of cardiogenic cerebral embolism depended to a great degree on the underlying heart disease. Cerebral embolism after myocardial infarction showed a better remission of symptoms than embolism in atrial fibrillation. In the group of valvular diseases the course of embolic strokes in mitral lesions was worse than in aortal valve disease. Prognosis was worst in endocarditis, both in view of neurological deficit and of mortality. Mostly, the cardiogenic emboli lead to infarctions of the middle cerebral artery territory (78 per cent) with a predilection for the left hemisphere. In media-syndromes the clinical course was significantly worse in patients with additional homonymous visual defect compared to incomplete infarctions. Initial disturbance of conscience reduced prognosis quoad vitam et restitutionem significantly. Of the neuroradiological findings, the detection of arterial occlusion or circulatory disturbance in angiography as well as the finding of an ischemic lesion in computed axial tomography (CAT) was correlated with a severe course of the embolic stroke. While 7 patients with hemorrhagic infarction in CAT-Scan showed no differences in the clinical course, the 14 patients with pathological cerebral spinal fluid findings in embolism had an unfavourable prognosis. The development of epileptic seizures did not influence the further course of the infarction to a significant extent. Results are compared with the current world literature.
