Anterior discectomy without fusion for treatment of cervical lateral soft disc extrusion: a follow-up of 120 cases.

One hundred and twenty patients with soft lateral disc herniation underwent surgery by anterior microsurgical discectomy and routine ablation of the posterior longitudinal ligament between 1976 and 1986. The study excluded patients with hard discs and soft disc extrusion with medullary symptoms. In our series 76.6% of patients were men. In 64% of the patients no causative factor was found. All of the patients presented with cervicobrachialgia; 53% also had a motor deficit. In 91.7% a single disc was involved. The last 40 cases were evaluated by computed tomography alone. In 51.5% an extruded disc was found. No permanent postoperative complication was encountered. All patients returned to their previous activities. Fifty patients underwent follow-up radiological evaluation at 1 and 5 years after the intervention and vertebral fusion was observed in 70% of these.

Perioperative lumbar injection of Ringer's lactate solution in chronic subdural hematomas: a series of 100 cases.

A series of 100 patients underwent surgical treatment for chronic subdural hematomas between 1979 and 1987. The procedure consisted of craniectomy with a 30-mm trephine, irrigation and drainage of the hematoma, laceration of the outer and inner membranes, and lumbar intrathecal injection of Ringer's lactate solution for immediate cerebral reexpansion (average injection, 130 ml). This technique gave the following results: 2% mortality, 2% moderate morbidity, and 96% recovery. The recovery of the patients was rapid, and good outcome was achieved in Grade 3 and Grade 4 cases (Markwalder's classification).

[Extra-medullary intradural melanotic tumor: apropos of a case of dorsal pigmented neurinoma. Review of the literature].

The authors report a case of pigmented thoracic neuroma (T3) discovered in a 40 year old woman on a routine chest x-ray. This hourglass-shaped extra-dural tumour was investigated by computed tomography, nuclear magnetic resonance imaging and iopamiron myelography. Treatment consisted of complete resection by T2-T3 laminectomy and left T3 foraminotomy. Light and electron microscopy revealed melanin secretion by the Schwann cells. A review of the literature confirms the findings observed in our case in terms of the slow clinical course, the benign nature and the excellent prognosis following complete resection, without the need for any radiotherapy or chemotherapy. The various histogenetic theories of extramedullary intra-dural melanotic tumours are reviewed. The difficulties of the differential diagnosis are discussed.

Modalities of origin of the middle cerebral artery. Incidence on the arrangement of the perforating branches.

In a series of 100 anatomical dissections on the basal brain arteries a case of real duplication at the middle cerebral artery level has been found. The importance of such a finding is discussed in the light of literature data. The knowledge of similar anatomical patterns is fundamental in the study of the lenticulostriate arteries arising from the sphenoidal segment of the middle cerebral artery. In fact the neurosurgeon must be familiar with all the possible variations of these perforators, given that the opening of the Sylvian fissure is by now an obligatory manoeuvre for the transcisternal access to the circle of Willis.
