Photocoagulation of cerebral arteriovenous malformations and arterial aneurysms with the neodymium: yttrium-aluminum-garnet or argon laser: preliminary results in twelve patients.

Six arteriovenous malformations (AVMs) and five arterial aneurysms (AAs) were treated with either argon or neodymium:yttrium-aluminum-garnet laser irradiation; one AVM was treated with both. All AVMs were occluded completely, leaving adjacent tissue untouched and preserving the regional vascularization. Photocoagulation produced varying effects on AAs: in one case an intraoperative rupture was sealed, in two cases the volume of an ectasia was reduced when the bleeding and thinner areas were coagulated, and in one case a saccular aneurysm was progressively and completely obliterated while the patency of the parent artery was preserved. These preliminary results are satisfactory; more experience will indicate how and when these new techniques can replace traditional ones or be used in combination with them.

The treatment of vascular malformation of the brain with laser source.

The first three cases of vascular malformations in humans (two artero-venous aneurysms and one saccular aneurysm) treated with the association of CO2 laser and Neodymium: Yag lasers, are presented here. The post-operative course has been very good. However, it is still necessary to examine a larger number of cases to see if, how, and when this treatment can be utilized in place of traditional methods.

Surgical treatment of spasticity in cerebral palsy.

Since 1971, we have surgically treated spasticity in 109 cases of cerebral palsy with posterior rhizotomy. The best results have been obtained with functional posterior rhizotomy, an original modification of Foerster's technique, in which the selection of the roots/rootlets to be sectioned is based on functional exploration of the spinal circuits involved in the maintenance of spasticity, using intraoperative electrostimulation on dorsal roots. This method makes selective sections possible, thereby saving a larger number of normal proprioceptive afferents, with consequent reduction in negative side effects. No recurrencies have been observed in our 3-year follow-up. The main indication is Little's disease.

[Diagnostic and therapeutic studies using the cryoprobe in various forms of facial pain, not of the migraine or trigeminal type].

The application of cold in neurosurgery (cryosurgery) has already clearly shown that it acts on the nervous structures in two opposite directions, depending on the temperature: i.e., at temperature from 0 degrees to --10 degrees, it stimulates the nervous fibres, and, at lower temperatures (below--80 degrees), it causes their destruction. On these bases we started our diagnostic researches and the treatment of certain forms of non-migraine nor trigeminal facial pain.

[Functional posterior radiculotomy, in the treatment of cerebral spasticity. peroperative electric stimulation of posterior roots and its use in the choice of the roots to be sectioned].

The authors present a modification of Foerster's Rhizotomy for the treatment of spasticity in cerebral palsy: functional posterior rhizotomy. The selection of the roots/rootlesses to be sectioned, is accomplished on functional data, based upon the analysis of the reflex responses to the intraoperative lumbar dorsal roots stimulation. With this method it is possible to selectively interfere with the pathological circuits responsible for hypertonia, saving proprioceptive afferences necessary for motor reeducation. The clinical results on hypertonia are the same as for total or partial rhizotomies, but sides effects (ataxia, hypotonia) are considerably reduced.
