Stroke has been recognised more frequently in children and represents a major cause of morbidity and mortality. It usually has an acute presentation, characterised by focal neurological signs, headache, altered state of consciousness or seizures. We report the case of an 18-month-male child with motor development disturbance, gait difficulty and pr...
Drooling or sialorrhea is the involuntary, passive spillage of saliva from the mouth due to inability to handle oral secretions. The medical, psychosocial and economic impact of drooling is underestimated. Treatment should always involve a multidisciplinary team and can include a medical or surgical approach. Various surgical techniques are used to...
RESUMEN El propósito de este estudio fue comparar la toraco-tomía convencional realizada para la ligadura qui-rúrgica del conducto arterioso permeable con una que llamaremos minitoracotomía, cuya longitud es menor. Población, material y métodos. Desde noviembre de 2000 hasta setiembre de 2002 se realizó ligadura quirúrgica de conducto arterioso per...
Los Testigos de Jehová, por razones puramente religiosas, se oponen a la utilización de sangre y sus derivados. Comunicamos la realización de una cirugía cardíaca compleja en un niño pequeño perteneciente a esta religión, sin utilizar sangre y sus derivados. Un lactante de 8 meses de edad y 5,4 kg de peso, perteneciente a la religión Testigos de Je...
Despite the progress made in cerebral aneurysm microneurosurgery, some morphologic and anatomic characteristics, or also clinical reasons, make surgical clipping of the aneurysmatic column difficult or unfeasible, justifying an endovascular therapeutic alternative. Despite the great progress made, the risk of endovascular intervention with microbal...
Hypertensive encephalopathy is a neurologic syndrome caused by a marked and rapid rise of blood pressure above baseline levels. Efficacy of current anti-hypertensive drugs greatly diminished the frequency of this situation in which diagnosis is essentially based on clinical parameters. This can justify the few papers found in radiologic literature....
van Gijn and co-workers identified "Perimesencephalic haemorrhage" (PM) as distinct, benign, non-aneurysmal subarachnoid haemorrhage. However, there is only one retrospective series of this entity outside the Netherlands.
to confirm (or not) the benign nature of perimesencephalic subarachnoid haemorrhage by evaluating its clinical course and long-t...
Aneurysmal bone cysts (ABC) are rare bone tumors of controversial pathogenesis. In 15% of cases, they are localized in the vertebrae. Despite the absence of anaplasia, their volume and localization are often responsible for incomplete surgical resection. The authors present 5 cases of primary vertebral ABC, 4 females and one male, localized in cerv...
Neurocysticercosis (NCC) is the most frequent parasitic disease of the central nervous system. Other Portuguese works showed it to be endemic in the north of our country. The purpose of this paper is to aid the characterization of NCC in the geographic area of our Institution. We retrospectively reviewed the findings of computed tomography (CT) in...
Angiography is usually recommended in perimesencephalic subarachnoid haemorrhage (PM SAH) to rule out a basilar artery aneurysm. However it is not known how often aneurysms are found among patients with a CT pattern of PM haemorrhage or the frequency of this CT pattern after rupture of posterior circulation aneurysms.
CTs of all SAH caused by poste...
The clinical importance of the cerebral aneurismatic lesion in well known. In Portugal we still do not have reliable statistics regarding the occurrence of the subarachnoid hemorrhage, however we can make a comparison through Kassel's and Drake's studies where they refer that annually 28,000 North-Americans suffer from subarachnoid hemorrhage attri...
Among 293 subarachnoid hemorrhages admitted to the Neurology and Neurosurgery departments of Sta Maria Hospital, 108 patients had a normal cerebral angiography. Twenty-three meet the radiological criteria for perimesencephalic hemorrhage (center of the hemorrhage located in front of the mesencephalon, without blood in the interhemispheric and later...
A case of a ruptured aneurysm arising from a duplicated segment of the intracranial portion of the vertebral artery is reported. This particular association, which can be explained by the embryological development of the vertebral artery, has not been described previously.
The efficacy of nimodipine in decreasing mortality and morbidity of subarachnoid haemorrhage (HSA) is evaluated in 51 patients admitted to the Neurological and Neurosurgery Departments of the Santa Maria Hospital. Reductions of 2 x (0.65, 6.39) of the incidence of ischemia in the total group and of 2.1 x (0.58, 7.79) of mortality in the sub-group w...
To analyze the factors that could influence early diagnosis and referral of subarachnoid hemorrhage (SAH), demographic, clinical and neuroradiological data of 112 cases of SAH admitted from January 1985 to December 1987 to our departments was compared between patients admitted in the first 24 h of onset (group 1, 56 patients), between the 1st and t...
The endovascular therapy in cerebral aneurysms has met significant technical progress, specially related with new microcatheters and different types of detachable balloons. Reviewing seven cases of giant cerebral aneurysms treated by intra arterial approach, the authors present their results pointing out and discussing the different angiosurgical t...
Several intra-arterial embolization techniques with polimerization substances, particles, thrombogenic coils and silicone and latex balloons have been used in the endovascular therapy of arteriovenous fistulas in different vascular territories. Using the Seldinger technique by femural route and with a coaxial system including a microcatheter with a...
A case of an aneurysm of the tip of the basilar artery in which occlusion of the sac with a detachable silicone balloon was performed, is reported. The indications and pitfalls of the technique are discussed.
A 30-year-old woman underwent surgical partial callosotomy (posterior half) for removal of an arteriovenous malformation. The patient submitted to neuropsychological evaluation before and after surgery for a period of 8 months. There was transient dysfunction attributable to disconnection of parietal, temporal, and occipital connections. Because th...
