Treatment for severe cerebellar infarction has been controversial. Clinical outcomes of patients with external ventricular drainage (EVD) and decompression as the first treatment for the infarction were compared. A total of 25 patients with severe cerebellar infarction were subdivided into two groups to compare outcome of the group (group A) with EVD with(More)
OBJECTIVE Symptomatic cerebral vasospasm is a major cause of disability and death in patients with aneurysmal subarachnoid hemorrhage. The purpose of this study was to determine the efficacy of intra-arterial infusion (IAF) of fasudil hydrochloride for symptomatic vasospasm in terms of neurological improvement and the angiographic features of cerebral(More)
We applied the arterial and venous occlusion technique in an in situ, isolated left lower lobe preparation of a dog lung to compare the effects of hypoxia with the effects of airway pressure elevation, and the infusion of serotonin, norepinephrine, and histamine. The total arteriovenous pressure drop across the lobe was partitioned longitudinally into(More)
Direct surgical intervention to treat ruptured basilar tip aneurysms in patients with moyamoya disease has rarely been attempted, and patients who have undergone such treatment have not fully recovered. We review six cases of surgically treated ruptured basilar tip aneurysm associated with moyamoya disease, including our own case to illustrate aspects of(More)
In 43 cases with symptomatic cerebral vasospasm after aneurysmal subarachnoid hemorrhage treated by intraarterial infusion of papaverine (IAP), we studied cerebral hemodynamics by measuring cerebral circulation time (CCT) using digital subtraction angiogram. CCT on the middle cerebral artery site was defined as CCT-LAV and on the anterior cerebral artery(More)
Male Sprague-Dawley rats (350-500 g) were made septic by intraperitoneal injection of 200 mg/kg cecal material in 5% dextrose in water (D5W; 5 ml/kg). Control rats (n = 11) received D5W. Preparations were studied on days 1 (n = 7), 3 (n = 7), and 7 (n = 8) of sepsis. In isolated hearts, ventricular function was depressed on days 3 and 7 of sepsis.(More)
High frequency chest wall compression (HFCWC) was studied as a method of assisting ventilation in six spontaneously breathing anesthetized dogs. Under a constant level of anesthesia, the dogs became hypercapneic after airflow obstruction was created by metal beads inserted in the airways. HFCWC was achieved by a piston pump rapidly oscillating the pressure(More)
CONTEXT Acute hemiparesis is a common initial presentation of ischemic stroke. Although hemiparesis due to spontaneous spinal epidural hematoma (SSEH) is an uncommon symptom, a few cases have been reported and misdiagnosed as cerebral infarction. DESIGN Case reports of SSEH with acute hemiparesis. FINDINGS In these two cases, acute stroke was suspected(More)
