[Intraoperative use of sonography in cerebral lesions]. / Zur intraoperativen Anwendung der Sonographie bei zerebralen Prozessen.

The advantages of intraoperative ultrasound are the localisation and biopsy of low grade subcortical gliomas of small deep seated lesions, e.g. metastasis, puncture of brain abscess and cysts. Also the endoscopic approach for intracranial haemorrhage, the placement of catheters in narrow ventricles, the detection of foreign bodies or bony fragments in head injury. Therefore ultrasound helps in planning precise microsurgical approaches.

[Cerebrospinal fluid rhinorrhea in achondroplasia with hydrocephalus (author's transl)]. / Spontane nasale Liquorfistel bei Chondrodystrophie und Hydrozephalus

Cerebrospinal fluid rhinorrhea was observed in a 12-year old girl with achondroplasia and communicating hydrocephalus. The leakage ceased and did not recur after treatment by ventriculo-atrial shunting (Holter valve) without plugging the fistula. The pathogenetic factors in this case are discussed.

[Objectivation of psychic alterations in patients after hypophysectomy (author's transl)]. / Versuch einer Objektivierung psychischer Eigenschaften von Patienten nach subfrontaler Operation von Hypophysentumoren

17 patients who had undergone transfrontal hypophysectomy were compared as regards their performance in the MMPI Saarbrücken and the Rosenzweig-Picture-Frustation Study with an equal number of patients who had undergone comparable head surgery. The results suggest that the psychic alterations revealed in these tests may be regarded as unspecific consequences of the operative method.

[Dorsal stabilization in dislocated fractures of C-1 and C-2 vertebrae with Palacos and wiring]. / Dorsale Stabiliserung bei Luxationsfrakturen des 1. und 2. Halswirbels mit Palacos und Drahtumschlingung

During 1 year 6 patients with dislocated fractures of C-1 and C-2 vertebrae (fractures of the odontoid process) and 1 patient with a pseudarthrosis of the odontoid process have been treated. 6 patients have been treated surgically by internal fixation of the arch of C-1 and C-2 spinous process by wiring and plastic material (Palacos). No complications occurred. The advantage of the method was early mobilization of the patients and reduction of hospitalization. Clinical and radiographic follow-up studies showed stable fusion on Flexion-extension X-rays and boney union of the fracture of the odontoid process.

[Early and late results after coating intracranial aneurysms with biobond (author's transl)]. / Früh- und Spätbefunde nach Biobond-Beschichtung von intrakraniellen Aneurysmen

Fifteen patients with intracranial aneurysms have been treated by coating the aneurysms with Biobond. Three patients died in the postoperative period. Only one patient had recurrent haemorrhage one year after operation. In this case the sac had not been wrapped completely at operation. Histological examination of this aneurysm revealed macrophage reaction and signs of slow disappearance of the plastic. Ten patients, who were followed up for a period of 3 to 8 years after operation, had no recurrent haemorrhage and were in good clinical condition, 8 of them doing full-time work. No complications caused by the material have been encountered. In 5 patients carotid angiography was performed after operation. In 2 cases the size of the aneurysm was diminished and in 3 cases was unchanged. There were no signs of thrombosis or narrowing of the adjacent arteries. We believe that Biobond is suitable for coating intracranial aneurysms that cannot be treated by clipping or ligature. As Biobond in vivo seems partially to disappear after long periods, it should be applied in thick layers.
