摘要:

Spontaneous brain hemorrhage accounts for about 10% of all strokes and is fatal in about 50% of the cases. Its incidence, in contrast to other types of strokes, has not declined. Hypertension accounts for about half of these hemorrhages; the rest are due to tumors, aneurysms and vascular malformations, inflammatory and degenerative vasculopathies and hematologic and iatrogenic disorders of coagulation. In some patients no cause is ever found. Hypertensive brain hemorrhage occurs in the deep gray nuclei of the hemispheres, the cerebellum, and the pons and results in specific clinical syndromes depending on the location. Computerized tomography has revolutionized the diagnosis of brain hemorrhage and is resulting in the development of rational criteria for medical and surgical management of these lesions. Intensive medical therapy guided by clinical status and continuous monitoring of ICP may improve outcome. Surgical removal of the hematoma is indicated in lobar and putaminal hemorrhages when the patient is deteriorating in spite of vigorous medical therapy. In addition most large (greater than 3 cm) cerebellar hemorrhages, as well as smaller cerebellar hemorrhages that result in significant brain stem compression should be evaluated. The roles of intensive medical therapy, elective late surgery and of immediate operation in improving eventual functional outcome need to be investigated further.

摘要:

Seventy-four patients with hypertensive putaminal hemorrhage (HPH) were followed at least 6 months after treatment and estimated by ADL. They were graded according to the state of consciousness on admission. The grading consists of 6 grades: Grade 1, fully conscious; Grade 2, somnolent; Grade 3, stuporous; Grade 4, semi-comatose; and Grade 5, deeply comatose. Removal of HPH was performed in 18 patients and conservative treatment was done in 56 patients. The mortality in surgically treated group was 28% while that in conservatively treated group was 14%. The patients who returned to full work or independent life without disability and with minimal disability after surgical treatment were, 50% in Grade 1, 33% in Grade 2, and 50% in Grade 3. The patients without disability and with minimal disability after conservative treatment were; 87% in Grade 1, 80% in Grade 2, and 22% in Grade 3. None below Grade 4 returned to full work or independent life in both groups. There was good correlation between the state of consciousness and CT findings on admission. There was no correlation between good recovery and the side of HPH. Our results do not support the view that the surgical treatment is superior to the conservative one in the management of HPH.

摘要:

This report concerns a clinico-pathological study of 60 patients afflicted with primary pontine hemorrhage. The illness was fatal in 43, 17 patients survived. Ophthalmic signs, autonomic disturbances and transient visual hallucination were observed and discussed. A ruptured microaneurysm within the border of a pontine hematoma was detected in this study, and in the first report of such a finding.

摘要:

The present study deals with the factors affecting the prognosis in the acute stage of 29 cases with hypertensive thalamic hemorrhage diagnosed by CT scan. It was thought that the following factors were significantly related to the outcome of the patients who were unable to lead daily life, remained in vegetative state or died: (1) consciousness level was below 10 in the so-called 3-3-9 formula, (2) bilateral Babinski's signs were observed, (3) localization of the hematoma was all the thalamic nuclei type, (4) hematoma volume was above 10 ml, (5) the maximum dimension of hematoma was over 30 or 35 mm, maximum width over 30 mm, maximum length over 25 mm and maximum height over 30 or 40 mm, and (6) the ventricles were dilatated. The prognosis had no significant relationship with the age of the patients, the side of the hematoma, the presence or the absence of ventricular penetration of the hematoma, or the existence of midline shift. We believe that in the acute stage of hypertensive thalamic hemorrhage, the prognosis can be forecasted by neurological findings, accurate calculation of the hematoma volume and size, localization of the hematoma and presence or absence of ventricular dilatation as determined by CT scan.

摘要:

The occurrence of secondary brain stem hemorrhage was studied in 435 autopsies from patients with recent cerebral hemorrhage, infarction or ruptured cerebral aneurysms. The frequency of secondary brain stem hemorrhage was found to be 45% in cerebral hemorrhage, 15% in cerebral infarction, and 36% in ruptured aneurysms. In the majority of cases the secondary brain stem hemorrhage occurred a few days after the onset of cerebral hemorrhage or infarction. Ruptured aneurysms showed a more widespread temporal distribution of secondary brain stem hemorrhage. The median survival time was 2 days in cases of cerebral hemorrhage, 4 days in ruptured aneurysm and 4 days in cerebral infarction. The frequency of secondary brain stem hemorrhage was significantly lower in patients younger than 20 years. No significant difference was found in its distribution between the sexes. Secondary occipital lobe infarction was present in 3.5% of the patients. It is concluded that secondary brain stem hemorrhage is a common major contribution to the cause of death in stroke.

摘要:

A 44 year old hypertensive man presented with a pure motor hemiparesis, and CT scan showed a putaminal hemorrhage. The clinical course was characterized by rapid resolution of the deficits. This case illustrates a variety of putaminal hemorrhage of good functional and vital prognosis, and stresses the value of CT scanning as a tool for diagnosis and prognosis.

摘要:

A clinicoanatomic study of 12 patients with tegmental-type primary pontine hemorrhage proved the presence of a gustatory disturbance among other clinical symptoms on the same side of the tongue as that of the pontine lesion, and suggested the secondary pathway of gustatory sensation from the solitary tract nucleus ascends without decussation in the homolateral pontine tegmentum. These results contradict textbook descriptions regarding the human secondary gustatory pathway.

摘要:

A variety of platelet function tests were performed in patients with four forms of obstructive cerebrovascular disease (CVD); transient ischemic attacks (TIA), reversible ischemic neurological deficit (RIND), cerebral infarct, and cerebral embolism of cardiac source in rheumatic valvular heart disease (RVHD). Platelet studies included platelet aggregation induced by ADP and ristocetin, spontaneous platelet aggregation, von Willebrand factor (VIII:vWF), platelet aggregation enhancing factor (PAEF), and percentage of large platelets (megathrombocytes). Serial testing was carried out in acute stroke patients. The effect of aspirin therapy was also evaluated. A clear difference in results was observed between patients with cardiogenic embolism and those with other forms of CVD. In patients with TIA, RIND, and cerebral infarct, platelet aggregation, both induced and spontaneous, was enhanced along with elevation of plasma VIII:vWF and PAEF, and increased percentage of megathrombocytes. In patients with cardiogenic embolism, however, these studies were negative except for percent megathrombocytes. This value was increased in the embolic patients with RVHD in comparison with non-embolic patients with RVHD. Increase in platelet aggregation to ADP and percent megathrombocytes developed slowly over a week following stroke. Induced and spontaneous platelet aggregation, and percent megathrombocytes could be normalized with 600 mg aspirin p.o. These studies suggest that a systemic increase of hyperaggregable platelets and of plasma activators of platelet function exists in thrombotic CVD and may be related to its pathogenesis, while local hemodynamic factors may be more important in the thrombogenesis of cardiogenic embolism.
