[Techniques and results after embolization of meningiomas (author's transl)].

The different techniques and results are described for a total of 25 preoperative tumor embolizations in 21 patients with meningiomas of diverse localizations and extents. Transfemoral catheter techniques were superior to direct punctures of the carotid arteries because of the easier handling of the catheters, the better superselectivity of angiography, and, consequently, the more exact placement of the emboli. The results of the embolizations depended on the localization of the meningiomas. Meningiomas of the convexities (six patients) turned out to be particularly susceptible to complete embolizations. Satisfactory results were achieved operatively and histologically through embolization in meningiomas of the falx with large parasagittal expansion as well as in those of the lateral sphenoid wing, the sylvian fissure, and the cavum Meckeli (nine patients). Embolization of tumors which were localized exclusively at the falx, the tentorium, or of more medially situated meningiomas of the sphenoid wing were without beneficial effect, since these are predominantly vascularized by branches of the internal carotid arteries. Provided the localization and vascularization of a tumor are favourable the application of superselective angiography and preoperative embolization represents an important improvement of the basic conditions for a later operation.

[Indications and value of treatment by catheter occlusion (author's transl)].

The value of the catheter occlusion therapy is analyzed in 92 cases retrospectively, and the indication, and complication risk of these procedures are considered. In the following vessel areas occlusion with different methods have been performed with decreasing frequency; kidneys, pelvis, legs, gastrointestinal tract, external carotid and internal carotid artery. Serious complications have been observed in therapeutic investigations at the head, especially in occlusions of the external carotid artery. In this group embolisation therapy should be performed with strict indication only.

A new variety of "empty sella" with cystic intrasellar dilatation of the recessus infundibuli.

A new variety of the "empty sella" consisting of polycystic intrasellar dilatation of the infundibular recess is described. The underlying embryonal developmental anomaly of the pituitary gland and diaphragma sellae and the possible effect of increased intracranial pressure are discussed and the malformation is compared with embryonal stages of ventricular development.

[Doppler-sonographic control of a carotid-cavernous fistula occluded by balloon catheter (author's transl)].

Angiographic and Doppler-sonographic findings from a patient suffering from a traumatic carotid-cavernous fistula are presented. Data were obtained before, during, and after occlusion of the fistula by means of a balloon catheter. Doppler examination of the periorbital vessels and the carotid arteries in the neck region (selective for the common, internal, and external carotid arteries) allows a reliable and atraumatic evaluation of the carotid circulation and the pathologic venous drainage of the fistula by the orbital veins. The proper positioning of the balloon therefore is facilitated by simultaneous Doppler recording of the pathologic venous flow. The balloon-catheter technique described by Prolo et al. (1971) was modified and lead to a complete occlusion of the fistula without causing a carotid thrombosis.

Plexiform neurofibroma (Rankenneurofibrom) of the cauda equina.

The clinical and neuroradiological findings in a rare case of plexiform neurofibroma with bone scintigraphy, myelography and selective spinal angiography are described. The difficulties with the preoperative differential diagnosis from other intraspinal space occupying lesions are discussed and the importance of intraoperative biopsy and electrical stimulation is stressed.

[Knotted neurinoma or plexiform neurofibroma in the cauda equina (author's transl)].

A rare case of a plexiform neurofibroma in the cauda equina is reported. In literature single cases are described as "redundant or knotted nerve roots", but mainly without microscopic description. Our patient was complained of bilateral pain in the legs for several years. The myelogram revealed a complete block with a serpentine-shaped structure. In operation we found a elongated and redundant nerve root in the cauda equina. The biopsy showed a plexiform neurofribroma. The operative technique is described.

[Embolization in neurosurgery (author's transl)].

Based on the literature and own experiences the indications for embolization in neurosurgical diseases are presented. This procedure is used for the treatment of arteriovenous malformations and fistulas, preoperatively in richly vascularized neoplasm and non operable tumors. Modern techniques (super-selective angiography, double-lumen balloon-catheter and catheters with detachable balloons) enable to occlude the territory of A. carotis ext., the cavernous portion of A. carotis int., the cervical portion of A. vertebralis, and the dorsal spinal radicular arteries. Complications are rare. There is a limited indication for embolization of the intracerebral area and the territory of A. spinalis and the ventral radiscaular arteries because of additional damage of the central nervous system. Various techniques and possible complications are discussed and own cases are presented.
