Post-dural puncture headache is a common outcome following either spinal or epidural anesthesia. Cases were collected within five years' period (1988-1992) in Keelung Chang Gung Memorial Hospital. Those cases with relief of post-dural puncture headache after conservative treatment were excluded. There were 159 cases, 128 female patients and 31 male patients. Age ranged from 16-63 yrs. Post-dura...

Spinal cord herniation (SCH) is a rare disease characterized by herniation of the thoracic spinal cord through an anterior dural defect, presenting with progressive myelopathy. A case of a 69-year-old woman who presented with Brown-Sequard syndrome and a bone defect, in which an osteophyte created a hemisphere-like cavity with spinal cord herniation, is presented. The strangled spinal cord was ...

∑ Herniation of the spinal cord through a dural defect is a rather rare deformity and very easily misdiagnosed as retromedullary occult intraspinal arachnoid cyst or meningocele. The possible origin of the dural defect can be traumatic, iatrogenic or unknown, so in these cases, congenital with great probability. On the thoracal part of the spinal column it shows a rather characteristic and misl...

An 18-year-old man with Marfan syndrome and migraine headaches presented with acute worsening of headaches with postural changes following spinal fusion surgery for scoliosis. Lumbar spine MRI done before surgery showed diffuse dural ectasia (figure 1). Brain MRI after surgery showed distended transverse and sagittal dural venous sinuses and an enlarged pituitary gland suggesting intracranial h...

BACKGROUND AND PURPOSE Spinal arteriovenous malformations (AVMs) are rare but debilitating lesions of the central nervous system. This study evaluated the outcome in patients with spinal AVMs treated surgically, and the relationship between outcome and the vascular anatomy of the lesions. METHODS These AVMs were classified into four types: dural AVM (type I), glomus AVM (type II), juvenile AV...

A 44 year old male patient, non smoker, hypertensive was admitted with loss of consciousness followed by transient weakness of the right side of the body. He gave a past history of recurrent TIAs. On admission, he was fully conscious and oriented. Pulse 60/mt, BP 120/80 mm Hg. There were no cutaneous telangiectasias. There was no carotid bruit. CVS S1 S2 heard normally. Central nervous system e...

Objective: Intracranial dural arteriovenous fistulas (AVFs) account for 10%-15% of all intracranial arteriovenous lesions. Some dural AVFs produce ocular symptoms include proptosis, diplopia, episcleral venous engorgement, periorbital swelling, extraocular muscle limitation, visual field defect, and papillaedema. Materials and Methods: We reviewed four patients who had dural AVFs with ophthalmi...

BACKGROUND AND PURPOSE The diagnosis of traumatic spinal dural tears is difficult to establish. The purpose of this study was to determine the reliable MR imaging findings suggesting dural tears in spinal burst fractures. MATERIALS AND METHODS We retrospectively reviewed spine MR images of 21 patients with dural tears (study group) and 33 patients without dural tears (control group), all of w...

With the use of Tracker and Balt microcatheter systems, intravascular pressure measurements were obtained in an experimental animal model, establishing the reliability of mean blood pressure measurements from these microcatheter systems. In the experimental model, selective occlusion of branches of the external carotid artery with simultaneous pressure measurements showed significant and reprod...
