Anterior displacement of the mandible for better exposure of the distal segment of the extracranial carotid artery.

Anterior displacement of the mandible (ADM) was performed in 34 patients undergoing surgery for malformations or atheromatous lesions of the distal segment of the extracranial internal carotid artery (ICA). This procedure greatly facilitates surgical access to the upper cervical region and has several advantages over mandibulotomy-mandibulectomy, namely: A shorter operating time, sparing of the inferior alveolar nerve and of the mandibular branch of cranial nerve VII, with no need for post-operative immobilization of the mandible. ADM permits the correction of ICA lesions extending as far as the first cervical vertebra. For lesions extending into the carotid canal ADM needs to be supplemented by various other procedures via the base of the skull.

High resolution real-time B-mode echotomography in the diagnosis of extracranial carotid lesions. Comparison with traditional angiography.

Sixty-three patients (115 carotid arteries) have been examined first by Dopplersonography, then by echotomography and finally by angiography using the Seldinger technique. The comparison between echotomography and angiography showed a sensitivity of 0.9, a specificity of 0.7 and a accuracy of 0.8. There have been 15 false positive results; in 14 of them the lesions were lower than 10% of lumen reduction and in one case there was a 10-45% stenosis. It seems that echotomography can better estimate lower degree lesions. It was difficult for echotomography to detect correctly the presence of an occlusion and to evaluate the surface aspect mainly in the presence of ulcerations.

Lumbosacral lipoma causing tethering of the conus: case report.

We report a case of tethered cord syndrome treated surgically. As in many reported cases, the treatment was successful on pain but only partially so on sphincter dysfunction. The most important diagnostic investigation is CT scanning with contrast medium.

Cysticercosis cerebri. Report on seven cases.

The authors report the clinical features, diagnosis and treatment of seven personal cases of cerebral cysticercosis. The epidemiology, anatomical location and therapeutic possibilities are studied. A brief review of the literature of 814 cases of neurocysticercosis is also reported.

Digitalized venous angiography in the investigation of the neck vessels.

An X-ray imaging system, using digital subtraction techniques, has been developed. The authors relate the results of a comparative study in 20 patients, affected by cervical occlusive vascular disease, whose arterial cervical system has been investigated both by conventional angiography and intravenous digital subtraction angiography. Indications, advantages and limitations of this new computerized apparatus are discussed.

Lumbar disc hernia secondary to gunshot injury.

The authors present a case of injury to the 4th lumbar root secondary to a gunshot wound. The lesion was not directly related to the traumatic action of the projectile, but was caused by the compressive action of disc material forced into the vertebral canal as a result of the destructive effects of a 7.65 caliber bullet.

Oculocerebral perforating trauma by foreign objects: diagnosis and surgery.

Two unusual cases of perforating oculocerebral trauma by foreign bodies treated surgically are reported. Both were caused by industrial accidents. In the first a nail shot from a nail gun ricocheted off the target and crossed the right eyeball and the posterior wall of the orbit, lodging in the homolateral temporal lobe. In the second case a metal fragment expelled by an agricultural machine penetrated the left maxillary sinus, crossed the floor of the orbit, the eyeball and the roof of the orbit and lodged in the homolateral frontal lobe. After accurate neuroradiological examination the patients were operated using simultaneous transcranial and transorbital access. In our opinion this is the only approach which can minimize the risk of infection which is so dangerous in this type of trauma. The functional and aesthetic results, which were very satisfactory in both cases, seem to confirm the correctness of this approach.

Intraspinal hemangiopericytomas. Report of two cases and review of the literature.

A description of two cases of intraspinal hemangiopericytoma is given, which join the 30 reported to date. The clinical features of this tumor rarely found in the CNS are compared with those of the same oncotype found at other sites. Surgical treatment is necessary, accompanied by radiotherapy. Spinal tumor embolization preoperatively is of benefit.

[Mediatinitis and thrombosis of the innominate veins and the superior vena cava: a rare complication of ventriculo-atrial shunt].

A thrombosis of bilateral Innominate and superior Cava veins, as a complication of ventriculo-atrial shunts, is described whose particularity resides at the rareness of the aetio-pathogenetic cause connected to an infectious process (mediastinitis) secondary to the infection of the neck's skin wound through the rejection of the venous catheter formed.

Delayed neurological bladder after cervical trauma.

We report a case of neurological bladder (upper motor neuron type) which appeared after a few years after vertebral trauma with retrodislocation of C6. We presumed that there was a traumatic and spondylosic etiopathogenesis of the disturbance. Surgery was done following the surgical techniques used in spondylogenetic myelopathies and there was an immediate improvement of the urinary disturbance.
