Complications associated with cerebral venous thrombosis.

Although CVT is associated with a good outcome in the majority of cases, it may be complicated by numerous unique and sometimes rare complications. The purpose of this review is to discuss the acute and chronic complications of CVT in greater detail. Awareness may lead to a more aggressive approach in those in which these complications are anticipated and perhaps avoided. The complications of CVT may be temporally divided into those unique to the acute stage and those that are associated with the chronic stage of CVT. They are venous infarction and haemorrhage, subarachnoid haemorrhage, a rapid progression and pulmonary embolism. In the chronic stages of CVT, one may encounter dural AV--fistula, progressive psychiatric disease, residual epilepsy and recurrence. Cerebral venous sinus thrombosis is associated with unique acute and chronic complications, some of them may be avoidable, e.g. pulmonary embolism. The chronic complications are rare but are potentially treatable, e.g. dural AVFistula nidus obliteration with intervention.

Dural arteriovenous fistula of the transverse sinus with concomitant ipsilateral meningioma.

A 69-year-old female complained of headache and tinnitus. Computed tomography, magnetic resonance imaging, and angiography showed a tumour in the right transverse sinus extending to the transverse-sigmoid sinus junction, a dural arteriovenous fistula (AVF), and right transverse-sigmoid sinus thrombosis with the downstream from the right sigmoid sinus involved by the tumour. Right external carotid angiography showed the tumour to be supplied by many branches of the right occipital artery, the posterior branches of the middle meningeal artery, and the posterior auricular artery, and the dural AVF fed by the occipital artery and the meningeal branches of the right vertebral artery. She underwent surgery via a combined right supra- and infratentorial approach. The tumour had invaded and blocked the right transverse sinus, which was resected. After surgery the patient was free of headache and tinnitus was diminished. Histological examination found that the tumour was a fibrous meningioma and that the orifice of the vein at the transverse sinus was blocked by the tumour. Serial follow-up cerebral angiography 2 months after surgery showed no change in the AVF, but 9 months after surgery confirmed disappearance of the AVF. This AVF was caused by occlusion of the right transverse sinus by the meningioma and was an acquired lesion.

[An unusual case of the otogenic purulent thrombosis of the sigmoid sinus and internal jugular vein].

The authors present a case of 51 years old female suffering from the purulent thrombophlebitis of the sigmoid sinus and internal jugular vein. The disease developed in the course of chronic otitis media. During first 2 weeks she was treated with antibiotics because of the septic fever without significant otogenic symptoms. An incidental otolaryngologic examination showed the reason of the illness. The authors emphasise the thrombophlebitis process extended from transverse sinus to the lower end of internal jugular vein. Nowadays the otogenic thrombophlebitis complications are rare, but the knowledge of them is indispensable in the everyday practice. The authors emphasise the necessity of cooperation otolaryngologists with other specialists. Especially it is important in the Polish new model of health service, which place the main role of the treatment to general practitioners.
