IGU treatment shows an early and sustained efficacy. Radiographically, no progression of GSS was evident in 16 (52%) patients at week 104. Gastric bleeding or gastric perforation warrants careful attention, especially in patients with concomitant use of both a non-steroidal anti-inflammatory drug and oral prednisolone.
A 24-year-old woman suffering from left trigeminal neuralgia presented with the familial occurrence of skeletal anomalies simulating Hajdu-Cheney syndrome. She was of a short stature and had low-set ears, protrusion of the bilateral temporal and occipital bones, platybasia, basilar impression, and dental anomaly. Vertebral angiography disclosed marked displacement to the left and dorsally of the basilar artery, which was confirmed during the operation to have compressed the left trigeminal nerve in the cerebellopontine angle narrowed by the unusually protruded bony structure. Cases of Hajdu-Cheney syndrome have occasionally been reported, a few combined with facial spasm, but Hajdu-Cheney syndrome with trigeminal neuralgia is very rare. The patient's family members were surveyed. The possible cause of the neuralgia with its relation to the osteodysplasia is briefly discussed.
A ruptured saccular aneurysm of the azygos pericallosal artery was found and clipped successfully in a woman of 47 years. Aneurysm of an azygos pericallosal artery is extremely rare.
SummaryA patient with an occipito-vertebral anastomosis associated with interesting clinical symptoms is presented. This 38-year-old male had a history of recurrent and reversible ischemic episodes of the vertebro-basilar system for more than 10 years . Surgical obliteration of this abnormal anastomotic channel resulted in gradual improvement of most of his clinical symptoms. The steal phenomenon of blood supply from the vertebro-basilar system to the external carotid artery via the anastomotic channel was thought to be responsible for clinical symptoms.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
