PURPOSE To determine whether the bony and soft-tissue obliterations of the intralabyrinthine fluid spaces reported in pathologic studies of patients with Cogan syndrome can be detected with MR or CT. METHODS The inner ears of six patients with Cogan syndrome were studied. High-resolution CT was performed in five patients; all six patients were studied with MR, including T1-weighted spin-echo ...

PURPOSE Exposure of premature human infants to hyperoxia results in the obliteration of developing retina capillaries, leading to a vision-threatening retinopathy termed retinopathy of prematurity (ROP). The authors hypothesized that this process may be mediated in part by endothelial nitric oxide (NO)-derived oxidants such as peroxynitrite and tested this hypothesis in a mouse model of ROP. ...

P re-operative diagnosis of pouch of Douglas (POD) obliteration is important for several reasons. We know that pre-operative identification of POD obliteration allows for the identification of women who may be at a higher risk of having underlying bowel endometriosis. In women noted to have POD obliteration at laparoscopy, there is a three times higher risk of concurrent bowel deep infiltrating...

Dural arteriovenous fistulas are contained within the dural leaflets, making them a unique shunt of central nervous system. Those without cortical venous drainage may be found incidentally or in workup pulsatile tinnitus ocular symptoms. These symptoms also occur setting drainage, but additionally, seizures, neurological deficits, even frank hemorrhage because disruption normal parenchymal outf...

Intervention treatment such as balloon retrograde or anterograde transvenous obliteration has been used for management of refractory hepatic encephalopathy as well as gastric variceal bleeding. Recently, plug-assisted retrograde transvenous obliteration without a help of balloon was newly developed to treat these patients. Here, we report three cases suffering refractory hepatic encephalopathy ...

Cerebral arteriovenous malformations (AVMs) are abnormal tangling between brain arteries and veins causing an arteriovenous shunt called nidus with an intervening network of vessels from the region of formation and spans through the brain. AVM effect is debilitating to the affected individual due to associated persistent intracerebral hemorrhage, resulting in significant occurrences of seizures...

The advantages, methods and results of surgical intracranial obliteration of aneurysms in conjunction with the use of intracranial or neck ligation of arteries were studied in 177 patients made up of the following groups: (a) internal carotid aneurysms-48, (b) anterior cerebral-anterior communicating-37, (c) middle cerebral-20, (b) basilar-two, (e) posterior cerebral-one. The overall mortality ...

This study evaluated the long-term angiographic results in large cerebral arteriovenous malformations (AVMs) partially embolized with isobutyl-2-cyanoacrylate. Preembolization, immediate postembolization, and long-term follow-up angiograms were performed in 30 large, partially embolized brain AVMs. Particular attention was paid to the relative size of the residual AVM nidus and the embolized ar...

During a forensic investigation, the determination of age at death is typically based on the level of skeletal development. Cranial sutures may help a forensic investigator to determine age at death since there is a predictable interval of age linked to their obliteration. The progression of the obliteration is divided in four stages (from 0 to 3), with the last stage indicating complete oblite...

OBJECTIVES This study was designed to evaluate the authors' experience with canal wall reconstruction (CWR) tympanomastoidectomy with mastoid obliteration in the treatment of chronic otitis media with cholesteatoma. STUDY DESIGN Institutional review board approved retrospective case review. METHODS Retrospective review was performed of all patients undergoing CWR tympanomastoidectomy with m...
