[Internal maxillary artery and collateral circulation in thrombosis of internal carotid artery (author's transl)].

From 53 cases of thrombosis of the internal carotid artery in the neck, collateral circulation through external carotid branches was angiographically demonstrated in 34 subjects. Anastomosis between external and intracranial circulations was seen to take place through three ways formed by internal maxillary, superficial temporal and facial arteries. The role of internal maxillary artery is emphasised as the most important pathway in the connections between the two circles.

Improvement of VEP photostress recovery test in patients with stenosis of the carotid artery and thrombosis of the internal contralateral carotid, after endarterectomy.

Nine patients with carotid stenosis and thrombosis of the internal contralateral carotid were examined by means pattern VEP (visual evoked potential) after photostress to evaluate if the disobliteration of the stenotic side may determine an increase in the overall blood supply to the brain. Our results permit to detect the increase of collateral blood flow to both hemisphere after carotid endarterectomy.

Subdural empyema and blindness due to cavernous sinus thrombosis in acute frontal sinusitis.

In this era of antibiotics, the complications of acute sinusitis are much less frequently encountered. Although orbital complications are most common, intracranial complications carry a high rate of mortality and morbidity. We describe a case of acute frontal sinusitis with subdural empyema and blindness due to cavernous sinus thrombosis and carotid artery thrombosis with a discussion of treatment of these complications and the etiology of blindness in sinusitis.

[Spontaneous thrombosis of lesion-free carotid arteries: a retrospective analysis of eight patients].

Strokes are rarely secondary to spontaneous carotid artery thrombosis. The objectives of this retrospective analysis were to define characteristic features and the clinical course. The study population included eight patients (6 females/2 males) seen at six university neurological centers. Age of onset was 46.5 years (range 38-52). Half of the patients had no vascular risk factor. Symptoms were TIA (n=1), strokes (n=7). Echotomography revealed intraluminal thrombus, with occlusion in 2 cases. Thrombi were found in common carotid artery (n=3), carotid bifurcation (n=2) and internal carotid artery (n=3). The thrombus was mobile in 4 cases. Seven patients were treated by anticoagulation therapy, one by surgery because of recurrent TIA. Further echotomographic exams revealed total resolution (3 cases) or decrease of the thrombus (3 cases). Occlusion was definitive in one patient. A cause was identified in six patients: acute leukemia (n=1), thrombocytopenic purpura (n=1), iron deficiency anemia (n=4).

[Rhinocerebral mucormycosis].

INTRODUCTION: Mucormycosis is a rare and acute fungal infection which is frequently lethal. The rhinocerebral form is usually seen in diabetics, but other localizations may occur in severely immunocompromised subjects. OBSERVATION: We report the case of a sphenoidal sinusitis associated with a probable cavernous sinus thrombosis and carotid artery thrombosis with middle cerebral artery territory infarction. Diagnosis was made on histological examination following sphenoidotomy. Early medical and surgical treatment led to a good outcome. CONCLUSION: The diagnosis of rhinocerebral mucormycosis should be considered in the clinical setting of necrotic sinusitis and acute neurologic deficit in diabetic patients. Early diagnosis and treatment are crucial factors leading to a good outcome.
