Intra-arterial occlusion of renal arteriovenous fistula using a detachable ball...
Campos, J G; Serviço de Radiologia, Serviço de Medicina III-B, Hospital Santa Maria, Lisboa.; Gomes, L B; Afonso, J R; Machado, J S; Schaller, J CSeveral 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 latex Debrun type balloon, the authors describe the selective o...
Intravascular therapy of giant cerebral aneurysm.
Campos, J G; Serviço de Radiologia, Hospital de Santa Maria, Lisboa.; Gomes, L B; Almeida, A; Coutinho, D; Pereira, R; Antunes, J L; Trindade, AThe 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 therapy that can actually be used. ; The endovascular therapy in...
Imaging findings in hypertensive encephalopathy.
Morgado, C; Serviço de Radiologia, Hospital de Santa Maria, Lisboa.; Antunes, L; Lima, A C; Gomes, L B; Campos, J GHypertensive 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. Nevertheless it is sometimes important to exclude ischemic or h...
Neurocysticercosis. An imaging analysis of 35 cases.
Morgado, C; Serviço de Radiologia, Hospital de Sta. Maria, Lisboa.; Gomes, L B; de Campos, J GNeurocysticercosis (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 35 patients with NCC, including 23 adults and 12 children. There...
Neuroradiology in the physiopathologic diagnosis of subarachnoid hemorrhage--ce...
Campos, J G; Serviço de Radiologia, Hospital de Santa Maria, Lisboa.; Gomes, L B; Almeida, A; Fernandes, A; Coutinho, D; Afonso, J G; Ferro, JThe 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 attributed to the rupture of the cerebral aneurysm. This is a clinica...
