BACKGROUND AND PURPOSE Percutaneous vertebroplasty is known for its pain-relieving effect. Our purpose was to evaluate its effect on the kyphosis angle, wedge angle, and height of the fractured vertebral body. METHODS We reviewed digital radiographs of 73 vertebral bodies in 53 patients before and after vertebroplasty. We measured the spinal kyphosis(More)
BACKGROUND The purpose of the current study was to investigate a hospital series of 986 cases of primary pediatric brain tumors in Taiwan. METHODS The authors reviewed the database of primary pediatric brain tumors in patients < 18 years of age collected in Taipei Veterans General Hospital (Taipei VGH) from 1975 to May 2004. Age and gender distribution,(More)
BACKGROUND AND PURPOSE Transarterial detachable balloon embolization of direct carotid cavernous fistulas (DCCFs) has become an optimal treatment. In a few cases, the parent artery has to be sacrificed to achieve morphologic cure. We present our experience with transarterial balloon-assisted n-butyl-2-cyanoacrylate (n-BCA) embolization of DCCFs in which(More)
OBJECTIVES To investigate the clinical pictures of patients with recurrent thunderclap headaches of unknown etiology and to field-test two relevant International Classification of Headache Disorders, 2nd edition (ICHD-II) criteria, i.e., primary thunderclap headache (Code 4.6) and benign (or reversible) angiopathy of the CNS (Code 6.7.3). METHODS We(More)
OBJECTIVE To estimate the prevalence of gout and to examine its risk factors among Taiwan's Aborigines compared with non-Aborigines. METHODS Data were collected from persons older than 40 years living in 3 aboriginal and 2 non-aboriginal districts in Taiwan by a community survey. Cases of gout were identified from self-reporting of a doctor's diagnosis(More)
Endoscopy has been applied for the management of pineal tumors and the associated obstructive hydrocephalus. The techniques include endoscopic third ventriculostomy (ETV), endoscopic biopsy, and endoscopic-assisted open surgery of tumor in selected cases. The purpose of this study is to report our experience and techniques of endoscopic surgeries for pineal(More)
BACKGROUND This study reports our experience in performing transarterial Guglielmi detachable coil (GDC) embolization for intracranial high-flow arteriovenous fistulas (AVFs) and evaluates its efficacy and safety. METHODS Over 3 years, 13 patients with 14 intracranial high-flow AVFs had been managed by transarterial GDC embolization in our institution.(More)
OBJECTIVE To investigate the evolution and clinical significance of vasoconstriction on magnetic resonance angiography (MRA) in patients with reversible cerebral vasoconstriction syndromes (RCVS). METHODS Patients with RCVS were recruited and followed up with MRA examinations until normalization of vasoconstriction or for 6 months. The vasoconstriction(More)
BACKGROUND This study investigated the causes of recurrent traumatic carotid-cavernous fistulas (RTCCFs) after detachable balloon embolization and evaluated the selection of embolic materials for endovascular treatment of the RTCCFs. METHODS Over a 10-year period, 116 patients underwent transarterial balloon embolization with occlusion of the fistulas and(More)
Surgical management of pediatric hypervascular brain tumors is challenging because of the risk of bleeding. We sought to evaluate the technical factors associated with safety and outcome of preoperative embolization of pediatric hypervascular brain tumors. Eight pediatric brain tumor patients received preoperative endovascular embolization during the past 8(More)
