We describe the imaging findings in a dural arteriovenous fistula (AVF) with unilateral subcortical calcification. A 50-year-old woman patient suffered from hypertension and chronic headache. Recently, marked headache and a changed consciousness level were noted. The imaging studies demonstrated left subcortical calcification and cerebral sulcus effacement. MR imaging and angiography revealed m...

SUMMARY Three cases of spontaneously closing dural arteriovenous fistulas (AVFs) are presented, and 11 previously published cases are reviewed. On the basis of clinical and angiographic data, two types of spontaneously regressing dural AVFs are distinguished: posttraumatic and spontaneous. In all cases, the explanation for spontaneous closure is unknown. Some authors have hypothesized that the ...

Background: Sacral dural arteriovenous fistulas (AVFs) are often undiagnosed at the initial presentation due to their rarity. Case Description: For 1 year, a 71-year-old man developed progressive motor and sensory disturbances in both legs. Magnetic resonance imaging showed spinal cord edema with mild contrast enhancement T9–10 T12 levels. Although venous dilatation was observed only cauda equi...

post spinal puncture headache (psph) is a well known complication of spinal anesthesia. it occurs after spinal anesthesia induction due to dural and arachnoid puncture and has a significant effect on the patient’s postoperative well being. this manuscript is based on an observational study that runs on babol university of medical sciences and review of literatures about current concepts about t...

BACKGROUND Although transvenous embolization (TVE) is an effective method for treating dural arteriovenous fistula (AVF), directing the catheter to the lesion site is difficult. OBJECTIVE We report on the utility of a quadruple coaxial catheter system for TVE. MATERIALS AND METHODS The quadruple catheter system comprised a 6 Fr guiding sheath, 6 Fr guiding catheter, 4 Fr intermediate cathet...

conclusions there is no difference between median and paramedian approaches with respect to pdph incidence; the paramedian approach is therefore recommended, especially for older patients with degenerative changes in the spine and intervertebral spaces and those who cannot take the proper position. moreover, the rate of pdph was found to be significantly higher in females than in males. results...

introduction: post dural puncture headache is still a common complication among young women undergone cesarean section, although use of small size spinal needles reduced its prevalence. several methods have been suggested for prevention and treatment of this side effect; such as complete bed rest, hydration, non-opioid analgesics, caffeine, codeine, which none of them proved to be totally effec...
