Para su tratamiento se ha utilizado el concepto Bobath. Durante el mismo, tuvo una frecuencia de tres sesiones por semana de 45 minutos durante cuatro meses. El paciente mostraba como problema principal, un pie con gran tendencia al equ Directory of Open Access Journals Sweden.
Variables such as age, sex, preoperative neurologic state, surgical moment, complications and status on discharge were analyzed. Acute posterior multifocal placoid pigment epitheliopathy associated with cerebral vasculitis. Acute multifocal posterior placoid pigment epitheliopathy APMPPE is an unusual self-limited retinal disorder that has been associated with various systemic complications.
To our knowledge, three prior cases associated with cerebral vasculitis have been described. This article describes a patient with APMPPE and angiographically documented cerebral vasculitis who was notable because of a the presence of two different cerebral ischemic events, occurring 1 month apart, and b the long latency 3 months between the onset of ocular symptoms and the second cerebral ischemic event.
Macroscopic and radiological anatomy of early branches of the middle cerebral artery. Full Text Available Las ramas precoces de la arteria cerebral media son ramas corticales originadas del tronco de la citada arteria. De los mismos, 16 fueron temporales, 1 frontal y en 2 casos no se pudo determinar su destino.
The early branches of the middle cerebral artery are cortical branches that arise from the trunk of this artery. These branches can supply significant areas in the temporal, frontal or insular lobes. We studied 20 cerebral hemispheres of formalin-fixed adult cadavers and 20 silvian angiographies in order to compare and correlate them.
Full Text Available Stroke after internal jugular venous cannulation typically leads to acute carotid or vertebral arteries injury and cerebral ischemia. We report the first case of delayed posterior cerebral infarction following loss of guide wire after left internal jugular venous cannulation in a year-old woman with a history of inflammatory bowel disease. Our observation highlights that loss of an intravascular guide wire can be a cause of ischemic stroke in patients undergoing central venous catheterization.

Abstract Recent findings have challenged the existence of category specific brain areas for perceptual processing of words and faces, suggesting the existence of a common network supporting the recognition of both. We examined the performance of patients with focal lesions in posterior cortical Seven right-handed patients with unilateral brain damage following stroke in areas supplied by the posterior cerebral artery were We examined word and face recognition using a delayed match-to-sample paradigm using four different categories of stimuli: cropped faces, full faces, words, and cars.
Reading speed and word length effects Clinico-anatomical correlations of left posterior cerebral artery occlusion. The relation between neurological signs and symptoms and computed tomography CT and magnetic resonance imaging MRI was examined in 11 cases of occlusion of the left posterior cerebral artery.
All the patients were righthanded. Right homonimous hemianopia was noted in 8 cases, right upper quadrantanopia in 2 cases, and right lower quadrantanopia in 1 case. Of the 11 cases, alexia without agraphia was noted in 9 cases, all 9 of which showed lesions of inferior occipital cortex lingual and fusiform gyri and subjacent white matter. Lesions of splenium were found in only 5 of the cases of alexia without agraphia. In 2 cases with neither alexia nor agraphia, lesions were seen in the medial occipital cortex and the subjacent white matter but not in the inferior occipital lobe.
Three patients had color anomia which was accompanied by memory disturbances and alexia without agraphia. In 2 of these 3, lesions were widespread in the region of the left posterior cerebral artery. Memory disturbances were observed in 6 cases, all of which also showed alexia without agraphia. The lesions extended not only of the inferior surface of the occipital lobe and along the interhemispheric fissure, but also of hippocampal and parahippocampal gyri.
In 3 cases of alexia without agraphia in which no memory distrubance was found, the symptoms of alexia were slight and disappeared at an early stage.
Endovascular treatment of posterior cerebral artery aneurysms using detachable coils. Aneurysms of the posterior cerebral artery PCA are rare, and most of the studies reported in the literature in which the endovascular approach was applied were carried out on a limited number of patients with PCA aneurysms.
We retrospectively reviewed our cases of PCA aneurysms - at various locations and of differing shapes - that received endovascular treatment and evaluated the treatment outcome. From January to December , 13 patients eight females and five males with 17 PCA aneurysms nine fusiform and eight saccular were treated using the endovascular approach.
The age of the patients ranged from 20 to 67 years, with a mean age of 44 years. Of the 13 patients, ten presented with intracranial hemorrhage, and one patient, with a large P2 aneurysm, presented with trigeminal neuralgia; the aneurysms were asymptomatic in the remaining two patients. All 13 patients were successfully treated, with only one procedure-related symptomatic complication. Seven patients were treated by occlusion of the aneurysm and parent artery together; five patients, by selective embolization of the aneurysm; one patient, by partial coiling.
Although infarctions were found in two patients treated with selective embolization and in three patients treated with parent artery occlusion, only one patient with a ruptured P2 aneurysm treated with parent artery occlusion developed transient amnesia as an ischemic symptom. Posterior cerebral artery aneurysms can be treated safely with either occlusion of the aneurysm together with the PCA or with a selective coil embolization.
Infarctions may occur after endovascular treatment, but they are rarely the cause of a disabling symptom. The effects of superimposed tilt and lower body negative pressure on anterior and posterior cerebral circulations. Steady-state tilt has no effect on cerebrovascular reactivity to increases in the partial pressure of end-tidal carbon dioxide PETCO2. However, the anterior and posterior cerebral circulations may respond differently to a variety of stimuli that alter central blood volume, including lower body negative pressure LBNP.
Little is known about the superimposed effects of head-up tilt HUT; decreased central blood volume and intracranial pressure and head-down tilt HDT; increased central blood volume and intracranial pressure , and LBNP on cerebral blood flow CBF responses.
Here, we demonstrate that there are no differences in anterior and posterior circulations in response to LBNP in different body positions. Physiological Reports published by Wiley Periodicals, Inc. Aneurysms of the anterior and posterior cerebral circulation: comparison of the morphometric features. Intracranial aneurysms IAs located in the posterior circulation are considered to have higher annual bleed rates than those in the anterior circulation.
The aim of the study was to compare the morphometric factors differentiating between IAs located in the anterior and posterior cerebral circulation. A total number of IAs diagnosed between and were retrospectively analyzed.
All patients qualified for diagnostic, three-dimensional rotational angiography. IAs were assigned to either the anterior or posterior cerebral circulation subsets for the analysis. Means were compared with a t-test.
The univariate and stepwise logistic regression analyses were used to determine the predictors of morphometric differences between the groups. For the defined predictors, ROC receiver-operating characteristic curves and interactive dot diagrams were calculated with the cutoff values of the morphometric factors.
The number of anterior cerebral circulation IAs was Significant differences between anterior and posterior circulation IAs were found for: the parent artery size 5. The cutoff point in the ROC curve was 2. Aspect ratio and parent artery size were found to be predictive morphometric factors in differentiating between anterior and posterior cerebral IAs.
Tuberothalamic artery infarction following coil embolization of a ruptured posterior communicating artery aneurysm belonging to a transitional type posterior cerebral artery. A case report. There are many potential anatomical variations in the connection between the internal carotid artery and the posterior circulation through the posterior communicating artery PCoA.
We describe the endovascular treatment of an aneurysm arising near the origin of the PCoA belonging to a transitional type posterior cerebral artery. Coil embolization subsequently resulted in thrombo-occlusion of the adjacent PCoA causing thalamic infarction even though sufficient retrograde flow had been confirmed pre-operatively by Allcock's test.

Frequency of hemorrhagic transformation differs greatly among studies, and its risk factors have been usually studied in patients with anterior ischemic stroke who received thrombolytic therapy.
We evaluated, in a hospital-based series of patients with posterior ischemic stroke not treated with thrombolysis, frequency and risk factors of hemorrhagic transformation.
Patients with posterior circulation stroke were seen in our Department during the period January to December Demographic and clinical information were collected.
We estimated risk for spontaneous hemorrhagic transformation by means of uni- and multivariate logistic regression analyses. Hemorrhagic transformation was observed in 7 patients 5. Only clinical worsening was significantly associated with hemorrhagic transformation OR 6. Our findings indicate that patients with posterior have a low risk of spontaneous hemorrhagic transformation, suggesting that these patients might have greater advantage from intravenous thrombolysis.
This study included a total of patients 52 children and 80 adults who were diagnosed as by cerebral angiography having moyamoya disease. CT or MRI was performed to examine the location of cerebral infarction in all subjects. Cerebral blood flow and vasoreactivity to acetazolamide were measured in 80 patients before surgery, using single photon emission computed tomography SPECT. Its incidence was significantly higher in ischemic-type patients than in hemorrhagic-type and asymptomatic patients, and was higher in patients in the advanced stage of the disease.
We present a case of year-old woman, who was admitted to the Department of Neurology in the emergency mode, due to: instantaneous pupillary dilation mydriasis , ptosis of the left eyeball and double vision. We performed plain CT, panarteriography of cerebral vessels, CT angiography with RT3D volume-rendered three-dimensional reconstruction images.
On the base of imaging studies the diagnosis of giant saccular aneurysm of the left posterior communicating artery was established. The patient was operated on and the giant aneurysm of left posterior communicating artery was clipped, confirming radiological diagnosis. During operation and postoperative period no complications were noted.
