ABSTRACT
Lemierre syndrome is a rare condition arising from an invasive oropharyngeal infection, which leads to septic thrombophlebitis of the internal jugular vein and multi-organ septic embolization. Intracranial complications are rare but serious, including subdural empyema, cavernous sinus thrombosis, and internal carotid artery aneurysms. We report a patient with Lemierre syndrome with multiple intracranial complications despite aggressive antimicrobial therapy. The patient eventually required transsphenoidal endoscopic drainage of the sphenoid sinus to help eradicate the infectious source. We postulate that in patients with Lemierre syndrome with evidence of infection in the paranasal sinuses, endoscopic sinus drainage can be an adjunct to antimicrobial therapy in achieving infection control.

The aim of this study was to retrospectively assess the recanalization rate, factors associated with and time taken for recanalization to occur in a matched ruptured and unruptured aneurysm population that were treated with endovascular coiling.Ruptured and unruptured aneurysms treated between 2002 and 2007 were matched for aneurysm location, diameter and neck size. Recanalization rate, time to recanalize, re-treatment rate and clinical outcome were analysed. Ninety-eight matched ruptured and unruptured aneurysms (49 aneurysms in each group) were studied. 46.8% of aneurysms in the ruptured group achieved complete obliteration on the initial post treatment angiogram versus 34.7% in the unruptured group. The ruptured group had a higher rate of recanalization (40.4% versus 20.4%). 25.5% of aneurysms had significant recanalization in the ruptured group versus 6.1% in the unruptured group (p=0.009). The retreatment rate was higher in the ruptured group (21.3% versus 6%). Ruptured aneurysms took a shorter time to recanalize with a mean time of 5.3±3.8 months versus 12.4±7.7months (p=0.003). Multivariate logistic regression analysis found neck size (p=0.0098), wide neck morphology (p=0.0174), aneurysm diameter (p< 0.0001) and ruptured aneurysms (p=0.0372) were significant predictors of recanalization. The majority of patients in both groups had a good outcome with GOS=5 (85.7% and 83.7%) but two deaths occurred in the ruptured group.Ruptured and unruptured aneurysms showed significant differences in rate, degree and timing of recanalization, thus requiring different protocols for imaging follow-up post endovascular treatment. Earlier and more frequent imaging follow-up is recommended for ruptured aneurysms.
