Endoscopic transsphenoidal treatment in recurrent and residual pituitary adenomas--first experience.

AIM OF THE STUDY: The aim of the study has been the assessment of the endoscopic method in the surgical management of recurrent and residual pituitary adenomas, as concerns treatment efficiency, substantial complications, and its possible advantages for the operating surgeon and patient. MATERIAL AND METHODS: In Department of Neurosurgery, Silesian University School of Medicine in Katowice, between October 2001 and June 2004, 125 patients underwent endoscopic surgery due to pituitary adenoma. The analysis comprised 20 patients, who were operated on due to recurrent adenomas or residual tumour not completely removed during the first surgical procedure. The group of patients was composed of 9 women and 11 men. The youngest patient was 32 years of age, the oldest 79. The average age was 53.9 years. The analysed group had 14 non-functioning adenomas, 4 GH-secreting adenomas, 1 PRL-secreting adenoma and 1 ACTH-secreting adenoma. 19 of them were macroadenomas while 1 was a microadenoma. 11 of the 20 adenomas infiltrated the cavernous sinuses. The surgical procedures were performed by a stable team, composed of 2 neurosurgeons, a laryngologist and an anaesthesiologist. The surgery method was based upon the technique developed by Jho and Carrau, with own modifications of the operators. A rigid neuroendoscope having the diameter of 4 mm with 0 degrees and 30 degrees optics by Storz was used. The follow-up period after surgery was between 12 and 42 months, 24.2 months on average. RESULTS: Of the 20 cases, complete recovery was achieved in 40% of patients undergoing secondary surgical procedures. In the group of 11 patients with adenomas not infiltrating the cavernous sinuses, recovery was reported for 8 of them, that is 73%. No fatalities occurred. 7 cases of liquorrhoea occurred during operation, requiring reconstruction and sealing of the sella by means of tissue glue and artificial dura or freeze-dried human dura. In 1 case, despite the application of post-operative lumbar drainage, rhinorrhoea occurred one month after the procedure, which required endoscopic reconstructive treatment. In the same patient, a pneumoencephalocele was observed. The average time of the repeat surgical procedure using endoscopic techniques was shorter by 18 minutes than the repeat procedure using microscopic techniques. CONCLUSIONS: The endoscopic method is a safe, hardly invasive and efficient surgical technique in the treatment of recurrent and residual pituitary adenomas. Advantages which add to its attractiveness are also reduction of the procedure duration, very good visualisation of the operative field, absence of serious complications, less pain experienced after the surgery.

Endoscopic transnasal transsphenoidal treatment of pathology of the sellar region.

From October 2001 to the end of November 2002 in Department of Neurosurgery, Silesian University School of Medicine in Katowice 70 explorations of the sella turcica were executed using the endoscopic method. In 63 cases the operation was done because of pituitary gland adenomas. In one case the diagnosis was craniopharyngioma, in 1 chordoma of the clivus, in one glioma of the optic nerve, in 1 the reason for an operation was an empty sella syndrome and in 3 cases the pathological diagnosis was an amorphous masses. Patients were operated using the 4-mm diameter endoscope with 0- and 30-degree angled lenses, using the method according to Jho and Carrau with our own modifications. In all cases of adenomas the total removal of the tumour was obtained in 71.4 %. Permanent diabetes insipidus occurred in 4.3 % of all operated patients. In our series of patients we did not observe any postoperative CSF leak or rhinological complications. One patient died, corresponding to 1.4 % of all cases. We the recommend transsphenoidal transnasal endoscopic approach for use in the cases of sellar region pathology because of the advantages of the method for surgeon and for comfort of the patient.

Cerebral aneurysms in childhood.

OBJECTS: The aim of this work was to ascertain any clinical and anatomical factors allowing differentiation between aneurysms of childhood and those occurring in adults by comparing both groups. METHODS: Results obtained in a total of 17 children and adolescents aged up to 18 who had been operated on for cerebral aneurysm in our department from 1989 to 1997 (3% of all patients treated for subarachnoid haemorrhage resulting from ruptured cerebral aneurysm in this period) were compared with those in the adult group operated on in our department. In contrast to the situation in adults, there was a male predominance in our population. In children we found only 1 case of middle cerebral aneurysm and 1 case of multiple aneurysms. We also found a high rate of rebleeding in the paediatric group. CONCLUSIONS: We suggest that the very good outcome (100% very good results in patients operated on early) obtained and the high risk of rebleeding in children with cerebral aneurysm allow the recommendation of early surgery in children with ruptured cerebral aneurysms.

[Monitoring of neurophysiologic modalities during surgery for cerebellopontine angle tumors. Personal experiments].

The purpose of intraoperative monitoring of many modalities is to save some structures of the nervous system being at risk of damaging during surgical procedures. In cerebellopontine angle (cpa) tumour cases these nervous system structures can include cranial nerves (trigeminal, facial, cochlear, accessory), motor and sensory tracts localised within brainstem, and other. Continuous registration of somatosensory and auditory evoked potentials as well as electromyography of masseter muscle, orbicular muscle of eye and trapezius muscle during procedure is the method of brainstem, cochlear tract and cranial nerves status evaluation. Direct stimulation of cranial nerves within posterior fossa using bipolar electrode is the method of facial, trigeminal and accessory nerves localisation, especially in patients with large tumours. In Department of Neurosurgery Silesian University School of Medicine for intraoperative monitoring of many modalities in cpa lesion cases Nocolet Viking IV D unit with special IOM software is employed. Authors presented own experience in such method and effect in treatment of group of 15 patients operated with electrophysiological intraoperative monitoring.

How should we manage children after mild head injury?

There are many controversies concerning the management of children after mild head injury. Most of these patients achieve a full recovery without medical or surgical intervention. A small percentage of them deteriorate owing to intracranial complications. The goal of this study was to identify significant factors that might allow the identification of patients at risk of subsequent deterioration. Its secondary goal was to establish a clinical protocol for the management of mild head injuries in children. We retrospectively reviewed the records of 166 children and adolescents with head trauma who had Glasgow Coma Scale (GCS) or Children Coma Scale (CCS) scores of 13-15 at the time of admission. The patients were divided into five age categories: babies younger than 1 year, children 1-3, 4-6, and 7-14 years old, and adolescents 15-17 years of age. The largest age group consisted of children 7-14 years old (83 cases). There was a male predominance (2:1). The main causes of injury were traffic accidents (55 cases) and falls (53 patients). Neurosurgical procedures were required in 93 of the 166 patients (56%). The most common intracranial lesion was subdural and epidural hematoma (60 cases). In 26 children (15.6%) diffuse brain swelling was the only lesion. A skull fracture was found in 103 cases and was accompanied by epidural hematoma (HED) in 19 cases (18%) and by subdural hematoma (HSD) in 12 cases (12%). However, the 63 children without a fracture also included 18 (29%) who had HSD and 11 (17%) who had HED. In our population 165 (99%) of the patients obtained a very good or good result. None was left severely disabled or in a vegetative state. One patient with GCS 13 died of an infection. We concluded that skull X-ray examination is not sufficient to rule out intracranial hematoma. We recommend CT scanning and admission to hospital for 24-h observation for all children with minor head injury, because of the risk of delayed hematoma.

[Neurovascular compression within posterior cranial cavity].

30 years ago Janetta proposed neurovascular compression as an etiology factor of trigeminal neuralgia. Neuroanatomical, neurophysiological studies and observations during neurosurgical operations seems to confirm Janetta's suggestions. The conception of neurovascular compression was accepted also as an etiology factor in hemifacial spasm. There are more diseases of unknown etiology described in literature in which neurovascular compression as an etiological factor is suspected. The results of initial treatment of these diseases performed by neurovascular decompression were presented. We are described the methods of contemporary diagnostics of neurovascular compression syndrome. The difficulties with correct diagnostics were underlined. MRI and neurophysiological examinations were pointed out as the most useful in an evaluation of neurovascular compression syndromes.

Surgery or conservative treatment in children with traumatic intracerebral haematoma.

In contrast to the case of extracerebral haematomas, the criteria for operative treatment of traumatic intracerebral haematoma (TIH) are not clear. The purpose of this study was to find factors that would be helpful in reaching a decision for surgical or conservative treatment of TIH. We performed a retrospective analysis of 31 consecutive cases of TIH treated in our department. The following factors were estimated: age, mechanism of injury, initial GCS or CCS score, neurological deficits, coexistence of arterial hypotension and respiratory disturbances, and localisation and size of the haematoma. The outcome was evaluated according to a modified GOS. Treatment was surgical for 20 patients and conservative for 11. Patients with GCS or CCS scores of 3-8 were treated surgically significantly more often than those with higher scores. The other factors did not correlate with type of treatment. It seems, then, that the clinical status of the patient, especially the level of consciousness according to the GCS or CCS score, is the most important predictor of the need for surgery in children with TIH.

[A case of large myelomeningocele complicated with liquorrhoea in a 32-year old man].

A case is presented of a 32-year-old man with giant myelomeningocele situated in the lumbosacral segment of the spine. The patient was admitted to the department with manifestations of active liquorrhoea from the dorsal surface of the hernial sac. An X-ray examination was performed which demonstrated an extensive spina bifida from L3 to S2. The patient was operated on preparing the myelomeningocele gate. In the described case the attention is paid to the lack of other developmental anomalies of the nervous, urinary, and osteoarticular system.

The prognostic value of some clinical and diagnostic factors in traumatic intracranial haematoma.

In order to carry out the analysis of predictive values of some clinical and diagnostic features, 146 patients of the Neurosurgical Clinic of the Silesian School of Medicine, were examined in 1980-1986. All the patients were in coma when admitted while CT findings showed traumatic intracranial haematomas. The examination included neurological diagnosis and CT examination. The analysis of statistical discrimination let us specify the probability of predicting death or survival of every patient. On the basis of 10 prognostic factors applied, the compatibility of prognosis and the real outcome for patients who survived was 78.2% and for those who died 91.2%.

[Analysis of selected prognostic factors in patients with ruptured cerebral aneurysms operated-on in the early period].

An analysis of certain clinical and laboratory findings of 80 patients with ruptured intracranial aneurysms was done. All of them underwent an operation in acute stage. The following prognostic factors were analysed: age of patient, sex, number of previous subarachnoid hemorrhages (SAH), clinical status according to the Hunt-Hess scale, CT finding according to Fisher scale, location and number of aneurysms, time of operation, Nimodipine treatment, body temperature, serum sodium level, white blood count just before operation, mean blood pressure, coexistence of heart and kidney disease. A special computer programme was used to analyse the value of the above factors on follow-up and the final results of the ruptured intracranial aneurysms treated surgically in acute stage.
