The association of genetic factors and cerebral infarction (CI) has long been established. A positive family history alone is a recognized risk factor for CI and vascular events in general. However, there are certain inherited conditions that further increase the risk of stroke. These conditions are generally metabolic and mitochondrial genetic defects that have variable modes of inheritance. This article reviews major inherited metabolic disorders that predispose an individual to CI. Ten main conditions will be discussed: Fabry's disease, cerebrotendinous xanthomatosis, tangier disease, familial hypercholesterolemia, homocystinuria, methylmalonic acidemia, glutaric aciduria type I, propionic acidemia, ornithine transcarbamylase deficiency and mitochondrial encephalopathy, lactic acidosis and stroke-like phenomenon. 相似文献

There is no doubt that CT and MRI play a major role in the diagnosis and selection of optimal therapeutic strategies in cases of acute cerebral infarction. However, it is true that there is a wide variation in the scanning protocols as well as data analysis procedures; these differences in imaging studies could translate into a lack of control over therapeutic strategies, thereby undermining the quality of clinical practice. It is obvious that standardization of imaging procedures is mandatory; however, so far, no such project has been conducted either at home or abroad. With this background, a couple of multi-institutional working groups dedicated to the standardization and development of practical guideline for imaging procedures in the setting of acute cerebral stroke, are now in operation in Japan. 相似文献

Ninety two 50-year-old-or-more patients with acute (less than 72 hours) cerebral infarction involved middle cerebral artery region and hematocrit of 40% or more were prospectively randomised to either hemodilution group (by rapid venesection, venous infusion of autologous plasma and 500 ml dextran 40) or standard therapy group. Effects of hemodilution on acute cerebral infarction were evaluated by clinically neurological deficit scores, hemorheological parameters and size of infarction. The results of our clinical trial are: 1. Clinical efficacy of hemodiluted patients is significantly superior to that of standard treatment patients. Effective rates are 63.04% and 41.30% respectively (P less than 0.05). 2. At 48th hour after hemodilution there are profound decreases in hematocrit, blood viscosity at high shear rate and blood viscosity at low shear rate. These changes last more than four weeks. Whereas in standard group, hemorheological parameters do not evidently change. 3. Sizes of cerebral infarction do not distinctly change in both groups between at entry and at the fourth weekend after treatment. 相似文献

Treatment of right hemispheric cerebral infarction by hemicraniectomy 总被引:16,自引:0,他引:16
J B Delashaw W C Broaddus N F Kassell E C Haley G A Pendleton D G Vollmer W W Maggio M S Grady 《Stroke; a journal of cerebral circulation》1990,21(6):874-881
An anecdotal series of nine patients (three men and six women with an average age of 57 years) presented with progressive neurologic deterioration while on medical therapy for large right hemispheric cerebral infarction. Clinical signs of uncal herniation (anisocoria or fixed and dilated pupils, and/or left hemiplegia with right decerebrate posturing) were present in seven of these nine patients. Computerized tomography of the head confirmed mass effect from cerebral edema. It was the clinical judgment of the treating neurologists and neurosurgeons that each of these nine patients would perish unless surgical decompression of the infarcted brain was performed. Accordingly, each was treated with right hemicraniectomy and dural augmentation. Six patients demonstrated neurologic improvement on the first postoperative day. One patient, with a postoperative diagnosis of lung cancer, died 1 month after surgery. The remaining eight patients are currently living with their families with a follow-up period ranging from 5 to 25 months. Patient outcome as evaluated by the Barthel Index indicates that three individuals are functioning with minimal assistance and that the remaining six patients are functionally dependent. After rehabilitative therapy, four patients returned for elective cranioplasty. These results suggest that hemicraniectomy can be an effective lifesaving procedure for malignant cerebral edema after large hemispheric infarction. 相似文献

Treatment of massive cerebral infarction 总被引:3,自引:0,他引:3
Stroke is the third leading cause of death in the United States, with a person dying every 3 minutes of a stroke. Massive
ischemic stroke accounts for 10% to 20% of ischemic strokes, has traditionally been associated with a high mortality and morbidity,
and requires a unique management strategy. Recent advances in management, fueled by an increased understanding of the pathophysiology,
may help decrease mortality and improve outcomes. Rapid access to reperfusion therapies remains the most critical element
of stroke care and the cornerstone of therapy. This article focuses on newer therapies, including osmotic therapy, hypothermia,
maintained normothermia, strict glycemic control, induced hypertension, and hemicraniectomy, all of which show promise for
reducing mortality and improving functional outcome. These interventions have become integrated into neurologic intensive
care units around the world. They are complicated, require a high level of expertise, and carry a significant learning curve.
In order for these new management techniques to be effective, an expedited, aggressive, meticulous, and potentially prolonged
medical management approach is needed. To accomplish this there is a growing need for focused specialists in the areas of
neurointensive care and stroke. 相似文献

Computed tomography (CT) is widely used for early evaluation of acute strokes. Most importantly, CT excludes acute hemorrhage or other diseases mimicking ischemia. Therefore, CT is the main imaging examination in patients with brain ischemia and when antithrombotic agents are being considered. During the first hours after acute ischemic stroke, the CT does not usually show much in the first 24 hours. However, early abnormal findings on CT scan have been described such as the hyperdense middle cerebral artery sign (HMCAS), and reduced contrast attenuation of the cerebral parenchyma. HMCAS reflects arterial occlusion. Early parenchymal abnormalities, the attenuation of lentiform nucleus (ALN), loss of the insular ribbon (LIR) or hemispheric sulcus effacement (HSE) occur less frequently and they are positive criteria for cerebral in progress. Early parenchymal abnormalities might also predict subsequent infarct extension and hemorrhagic transformation. Therapeutic trials of ischemia in MCA territory involved decision making when the CT may not show obvious ischemic changes. Finally, initial CT findings may also help to predict response to therapy. 相似文献

Antithrombotic therapy in cerebral infarction] 总被引:10,自引:0,他引:10
N Tanahashi 《Clinical neurology》2000,40(12):1251-1253
Antithrombotic therapy for the acute stage of cerebral infarction consists of thrombolysis, anticoagulant therapy and antiplatelet therapy, and their indications depend on the clinicopathological type of lesion, time after onset, and severity of illness. Tissue plasminogen activator has been approved in the United States for use in cerebral infarction within 3 hours after onset. The usefulness of heparin as anticoagulant therapy at the acute stage of cerebral infarction was not proved by the International Stroke Trial due to hemorrhagic complication. A selective thrombin inhibitor (argatroban) is used in Japan for atherothrombotic cerebral infarction within 48 hours after onset. A selective thromboxane A2 synthetase inhibitor (sodium ozagrel) had been approved for cerebral thrombosis within 5 days after onset. Aspirin (160-300 mg/day) is effective, but slightly, in the acute stage of cerebral infarction by the International Stroke Trial and Chinese Acute Stroke Trial. To prevent recurrence of stroke in the chronic stage of cerebral infarction, antiplatelet therapy (with aspirin or ticlopidine) is used for atherothrombotic cerebral infarction, and anticoagulant therapy with warfarin for cardioembolic cerebral infarction. 相似文献

目的 探讨以CT脑灌注成像(CTP)指导下的急性前循环脑梗死溶栓治疗的优越性.方法 通过对比分析5例急性前循环脑梗死者"时间窗"、"缺血半暗带"、和溶栓干预疗效之间的相关关系,阐析以CTP结果指导下的急性前循环脑梗死溶栓治疗的优越性.结果 对急性前循环脑梗死患者进行CTP检查,如显示有缺血半暗带,即使超过溶栓时间窗,仍可进行溶栓治疗(本组有2例效果较好);对在溶栓时间窗内的患者,如CTP显示已有脑梗死形成,对该类患者进行溶栓治疗疗效欠佳(本组有3例).结论 以时间窗为指导的溶栓干预模式存在固有的局限性,对急性前循环脑梗死患者应行CTP检查,根据缺血半暗带来判断是否溶栓治疗,是一种较为理想的模式. 相似文献
