The correct radiographic identification of ossification of the pterygospinous and pterygoalar ligaments plays an important role in surgical procedures for the treatment of trigeminal neuralgia. Most of these procedures are performed through the foramen ovale, a site where these ligaments can be found to be partially or completely ossified. We studied the radiographic features of these ossified ...

background: one of the important etiologies for cryptogenic stroke is paradoxical embolization secondary to patent foramen ovale (pfo). foramen ovale can secondarily reopen due to pulmonary arterial hypertension (pah) which is common among the older age. pah is known as a frequent and life threatening complication of copd. the aim of this study was to determine the prevalence of pfo between cop...

Platypnea orthodeoxia is a rare disorder characterized by dyspnea and arterial desaturation, exacerbated by the upright position and relieved when the subject is recumbent. We report the case of a 79-year old woman admitted to hospital with dyspnea who was thought to have restrictive ventilatory impairment due to osteoporosis and severe kyphosis. Interestingly, the dyspnea was aggravated in the...

Patent foramen ovale and atrial septal aneurysm are considered to be factors conducive to the occurrence of stroke and transient ischaemic attacks. However, there is no clear answer to the question whether patent foramen ovale is an independent risk factor for stroke and what the mechanism of potential cerebral ischaemia in patients with an interatrial septal abnormality is. The paper presents ...

AIM To note the morphological variations and morphometric details of foramina ovale in dry adult skulls of Indian origin. MATERIAL AND METHODS 82 dry adult human skulls of unknown sex and of Indian origin were obtained and variations in appearance and number of foramen ovale were noted. The length and width of the foramina ovale of both sides were determined using digital Vernier calipers and...

background: percutaneous transcatheter closure has been proposed as an alternative to surgical closure or long-term anticoagulation in patients with presumed paradoxical embolism and patent foramen ovale (pfo). methods: there were two symptomatic patients (29 and 47 years old) who underwent percutaneous transcatheter closure of pfo after at least two events of cerebral ischemia; one embolic eve...
