[Pneumocephalus following facial injury].

Pneumocephalus or intracranial air its commonly detected following serious head injury and posterior fossa surgery. In laryngology the frequent reason of its appearance is also herniation of air through a break in the wall of skull due to advanced benign and malignant tumors. The pathophysiology involves the presence of craniodural fistula allowing ingress of air. A ballvalve mechanism may allow air to enter not exit the cranium or like in turned upside down bottle leak permit air entrance as fluid leaves the intracranial space. The presence of air is usually asymptomatic but caries a potential risk of increased intracranial pressure or meningitis which require an immediate therapy. Although various ways of treatment were reported prevention and early diagnosis are the most important. We report 3 cases of cerebral air that occurred secondary to the head trauma. The diagnosis every time promptly confirmed by skull roentgenogram or CT.

Clinical experiences with nimodipine treatment in patients after SAH and aneurysm surgery.

The authors present their 3-years experiences with nimodipine treatment in patient after subarachnoid haemorrhage (SAH). Nimotop has been used in treatment of SAH in the Department of Neurosurgery since June 1985. During 3-years 220 patients with subarachnoid haemorrhage were admitted to the Department of Neurosurgery in Wroclaw. Till the end of 1989 177 patients with SAH received nimotop therapy. Our results show that intravenous Nimodipine is well tolerated, and we have not observed any discontinuation effects, after we had introduced gradual diminishing doses of Nimotop. Nimotop does not prevent of developing vasospasm in all patients, but their outcome is better. The treatment of vasospasm should be complex (with nimotop and hypervolemic and hypertensive therapy).

[Giant aneurysm of the internal carotid artery, stimulating parasellar tumor].

The authors report a case of a giant aneurysm of the internal carotid artery filling from the left internal carotid artery below the site of branching-off of the posterior communicating artery. The initial neurological, and ophthalmological signs and plain films of the skull suggested presence of an Erdheim's tumour. It is worth stressing that the onset of the clinical manifestations was at the age of 15 years, particularly in the form of progressing binasal hemianopsia with sparing of the lower temporal quadrant. The efficiency of the cerebral circulation was tested using Mathas' test, electroencephalography, ophthalmodynamometry and angiography. It was decided to ligate the left carotid artery although Mathas' test during angiography was not as positive. The boy tolerated the operation well. Ophthalmological examination demonstrated after 18 months normal visual fields and normal visual acuity. Further follow-up during 8 years demonstrated normal psychosomatic development of the boy.

[Diagnosis of blood flow disorders in the common carotid arteries by the ultrasonic Doppler method].

The aim of this work was evaluation of the usefulness of the Doppler ultrasound method for detection of blood flow disturbances in carotid arteries. The investigations were done in 110 patients with symptoms of cerebral circulatory disorders. In 45 patients carotid arteriography was done. In 30 cases arterial reconstructive operations were performed. The curves of blood flow velocity in the common carotid arteries were recorded with a UDP-10 ultrasound blood flow detector. The obtained curves were subjected to morphological analysis and the mean momentary velocity of the systolic and diastolic flow wave was calculated. In 80% of cases with impaired patency of the carotid arteries demonstrated by angiography abnormal curves of blood flow velocity in the common carotid arteries were obtained. The method of ultrasound recording of blood flow velocity is non-invasive and safe and it is very useful for establishing indications to angiography and for postoperative control.
