Factors associated with proximal carotid axis occlusion in patients with acute stroke and atrial fibrillation.

Background: Patients with atrial fibrillation (AF) are more likely to exhibit proximal carotid axis occlusion than those without AF. However, clinical characteristics associated with proximal arterial occlusion (PAO) in acute stroke patients with AF are not fully known. This study was aimed to elucidate the factors correlated with PAO.

Microsurgical findings of Tolosa-Hunt syndrome.

Background: Tolosa-Hunt syndrome (THS), a nonspecific chronic inflammation of the cavernous sinus, is a rarely needed surgical manipulation, even for diagnosis, because corticosteroid therapy is markedly effective against this condition.

Methods: A 59-year-old man presented with left trigeminal neuralgia and right abducens nerve palsy 2 months after the improvement of right oculomotor nerve palsy by corticosteroid therapy. Radiological examinations showed a mass lesion in the left cavernous sinus.
