Radiofrequency thermocoagulation (RFT) via trans-oval approach is effective treatment modalities for trigeminal neuralgia. Clear identification of the foramen ovale (FO) most important initial step successful percutaneous procedures. The purpose this study was to verify whether medial end temporomandibular joint and distance between mandibular angle occipital inner line can be used as a fluoros...

The patent foramen ovale (PFO) is a normal interatrial communication during fetal life that persists after birth in approximately 1 of every 4 adults. PFO is a potential route for embolic transit from the systemic venous circulation to the brain. Though there is compelling circumstantial evidence implicating PFO, the precise role of PFO in the pathogenesis of cryptogenic stroke is not yet estab...

The foramen of Vesalius is a small, variable but consistently symmetrical structure located anteromedial to the foramen ovale and lateral to the foramen rotundum and vidian canal. It transmits an emissary vein through which the cavernous sinus and pterygoid plexus communicate. Fifty high-resolution CT scans of the skull base and two three-dimensional (Cemax) reconstructions were reviewed to det...

Patent foramen ovale (PFO) is not uncommondit appears in perhaps 10% to 25% of the populationdbut only a small percent of cases will produce any clinical sequelae, such as refractory hypoxia, orthodeoxia-platypnea syndrome, or migraine headaches. PFO is most notorious, however, for its association with paradoxical embolus and cryptogenic stroke (1). Conclusive proof of a causal relationship bet...

BACKGROUND Patent foramen ovale (PFO) is prevalent in patients with migraine with aura. Observational studies show that PFO closure resulted in migraine cessation or improvement in approximately 80% of such patients. We investigated the effects of PFO closure for migraine in a randomized, double-blind, sham-controlled trial. METHODS AND RESULTS Patients who suffered from migraine with aura, e...

Background and Purpose—We aimed to investigate the incidence of May-Thurner syndrome in patients with cryptogenic stroke with patent foramen ovale. Methods—This was a retrospective study. All consecutive patients with cryptogenic stroke having undergone patent foramen ovale closure from January 1, 2002, to December 31, 2007, at our institute were included in this study. Pelvic magnetic resonanc...

About a quarter of the adult population is known to have a patent foramen ovale, rarely accompanied by the presence of an interatrial septal aneurysm. A patent foramen ovale is found in more than 40% of patients younger than 60 years who had a cryptogenic ischemic stroke. Clinical and echocardiographic parameters allow the identification of patients at high risk of recurrence after a first cryp...

Patent foramen ovale is a congenital cardiac lesion that persists into adulthood and which is present in over 25% of the adult population. Its diagnosis, evaluation and treatment have attracted increasing interest as it has been suggested that it may be associated with various pathologic conditions, such as cryptogenic stroke, platypnea-orthodeoxia syndrome, decompression sickness and migraine....

A patient undergoing left ventricular assist had a complicated post-operative course due to a patent foramen ovale. This presented as a right to left shunt with desaturation of the arterial blood, and possibly contributed to paradoxical embolization resulting in neurological complications and death. A method is presented to determine the presence of a patent foramen ovale during left ventricula...

Migraine is one of the most common neurological disorders and one of the most frequent primary headaches. It imposes a significant burden on the affected individuals, society and health care system. As the etiology and pathophysiology of migraine are not well understood, treatment is largely symptomatic. Patent foramen ovale is a remnant of a fetal circulation and is highly prevalent in the gen...
