Cím:Tectal plate gliomas. Part III: Apparent lack of auditory consequences of unilateral inferior collicular lesion due to localized glioma surgery / Bognar L.; Fischer C.; Turjman F.; Michel F.; Villanyi E.; Mottolese C.; Guyotat J.; Lapras C.
Dátum:1994
Megjegyzések:The authors present one of their cases operated on for intrinsic tectal plate glioma. The complete resection of the right inferior colliculus (I.C.) had no apparent auditory consequences. The pre- and post-operative tonal and vocal auditory tests were normal. The brain-stem auditory evoked potentials (BAEPs) and middle latency potentials (MLPs) were recorded pre-, post- and intraoperatively. At the end of surgery all waves were present with a marked delay of wave V and a slight delay of the Pa component. The dichotic test showed a significant right ear extinction but admittedly much less important than expected. The role of inferior colliculus (I.C.) in hearing is discussed.

Cím:Tectal plate gliomas. Part II : CT scans and MR imaging of tectal gliomas / Bognar L., Turjman F., Villanyi E., Mottolese C., Guyotat J., Fischer C., Jouvet A., Lapras C.
Dátum:1994
Megjegyzések:CT scans and MR images were analyzed in 12 patients with histologically proved tectal plate gliomas. In an attempt to identify the nature of these lesions, their radiological characteristics were correlated with the histological results. In four of our patients CT scan failed to show the tumour. MR imaging demonstrated the tectal distortion in all cases. Contrast enhancement, calcification, cystic portions, exophytic nature were observed in both high and low-grade gliomas. We conclude that in the case of intrinsic tectal tumours, the most probable diagnosis is that of low-grade astrocytoma while in the case of exophytic tectal tumours, the differential diagnosis from pineal region tumour is required and a histological verification is necessary.

Cím:L'anévrysme intracánien rompu modulation de la chirurgie en fonction de l'état de consience et de l'age du patient : Expérience personelle sur 468 patients admis au cours de périodes (1972-1984 et 1985-1989) = Ruptured intracranial aneurysm. Modification of the surgical method based on the state of consciousness and age of patients. Personal experience with 468 patients admitted during 2 periods (1972-1984 and 1985-1989) / Deruty R., Mottolese C., Pelissou-Guyotat I., Bognar L., Oubouklik A.
Dátum:1999
ISSN:0028-3770
Megjegyzések:The management of the ruptured intracranial aneurysm (clinical grade I to IV only) is studied in a series including 140 patients admitted from 1985 through 1989, in which selected patients were submitted to early surgery and other patients were postponed for delayed surgery. The results are compared to those of an earlier series including 328 patients admitted from 1972 through 1984, for which the general attitude was the delayed surgery: in the later series; the selection for the timing of surgery was based on two main parameters: the clinical status and the patient's age. When we compare both series, the overall management results demonstrate an improvement of 10% of satisfactory results and a decrease of 10% in the death rate in favour of the later series; for the surgical results, the figures are respectively 6% and 5% in favour of the later series. The relationship between age and outcome shows a considerable improvement: over 50 years of age, we observed plus 25% of satisfactory results and minus 22% in death in favour of the later series. Similarly, the relationship between state of consciousness and outcome, demonstrated a great improvement: for drowsy and stuporous patients the figures are respectively plus 22% and minus 21% in favour of the later series. When we consider the later series alone, the patients were admitted at 4 intervals of time from S.A.H. (D0-3, D4-6, D7-15, D16 and over). The most favorable outcome was observed for those patients admitted late (after D7) and already stabilized.

Cím:Level of consciousness and age as prognostic factors in aneurysmal SAH / Deruty R., Pelissou-Guyotat I., Mottolese C., Amat D., Bognar L.
Dátum:1995
Megjegyzések:The prognostic value of the level of consciousness and the patient's age for the outcome of aneurysmal subarachnoid haemorrhage (SAH) is studied in 74 patients admitted on day (D) 0 to D3 after aneurysm rupture. For the level of consciousness three groups of patients are compared: grade I+II (alert patients), grade III+IV (drowsy patients), and grade V (comatose patients). For the age, two groups are compared: patients aged under 50, and patients aged 50 and over. The timing of surgery was: D0-D3 51%, D4-D6 20%, D7 and later 18%, and No surgery 11%. The overall management results were: Good (satisfactory result) 43%, Fair (moderately disabled) 18%, Poor (severely disabled+vegetative survival) 19%, and Death 20%. The outcome was strongly related to the level of consciousness, the rates of Good result decreasing from 71% (grades I-II) to 14% (grades III-IV) and to zero (grade V), and the mortality rates increasing respectively from 5% to 14% and 61%. The relationship between outcome and age was less marked: 54% Good result under 50 and 30% over 50. Out of the Grade V group, 56% could be operated upon and 44% died before surgery. No patient from the other two groups died before surgery. The literature concerning the Grading Systems published so far and the various prognostic factors are discussed.

Cím:Surgical management of unruptured intracranial aneurysms. Personal experience with 37 cases and discussion of the indications / Deruty R., Pelissou-Guyotat I., Mottolese C., Bognar L., Oubouklik A.
Dátum:1992
Megjegyzések:The authors report a series of 37 cases of unruptured aneurysms, admitted and operated upon over a 5 year period (1985-1990), which represents an incidence of 18% of the total number of aneurysm patients operated upon during this period. These unruptured aneurysms were discovered in 4 types of circumstances: 1) Associated with a ruptured aneurysm but treated in a second procedure (9 cases); 2) After a transient ischaemic attack (6 cases); 3) After a cerebral haemorrhage of a different origin (3 cases), 4) After the onset of various neurological symptoms other than SAH (19 cases). Giant aneurysms (over 2.5 cm in diameter) are excluded from this series. Overall these 37 patients harboured 52 aneurysms, and 1 patient was operated upon on both sides. 27 aneurysms (52%) were located on the right side, 15 (29%) on the left side, and 10 (19%) on the midline. In the immediate post operative period, 1 patient died (2.6%) and 8 patients (21%) presented various complications. The outcome at 6 months was: death 2.6%, moderately disabled 8%, good recovery 89%. The arguments in favour of, or against, the surgical treatment of unruptured aneurysms are discussed in view of the literature. In favour of prophylactic surgery are: 1) The rather poor overall outcome following aneurysm rupture (including deaths before admission); 2) The rather good outcome of surgery in published series of unruptured aneurysms. The data of the natural history of the unruptured aneurysm are more questionable: in this view, surgery seems to be recommended in young patients with an easily accessible aneurysm and being in a good clinical condition.

Cím:Tectal plate gliomas. Part I : microsurgery of the tectal plate gliomas / Lapras C., Bognar L., Turjman F., Villanyi E., Mottolese C., Fischer C., Jouvet A., Guyotat J.
Dátum:1994
Megjegyzések:A series of 12 patients with tectal plate gliomas, is presented treated by direct surgery. Mean age was 19 years. All patients presented with signs of raised intracranial pressure and supratentorial hydrocephalus on CT scan. Diplopia was the most common local sign. CT scan and MR imaging showed 4 intrinsic, 6 exophytic, and 2 ventrally infiltrating tectal tumours. The histological diagnosis was low-grade astrocytoma in 7, high-grade astrocytoma in 2, oligodendroglioma in one, oligo-astrocytoma in one, and ependymoma in one case. The suboccipital supra- and transtentorial approach was used in every cases. Tumour resection was generous at the level of the superior colliculi, but on the contrary, resection was limited at the level of inferior colliculi due to the auditory risk. Tumour removal was total (macroscopically) in 9 cases and partial in 3 cases. There were 4 surgical complications and one death related to surgery. Parinaud's syndrome was the most-common postoperative sequelae. Auditory hallucinations and the acoustic neglect syndrome were seen once. In three cases additional radiotherapy and chemotherapy were given once with severe sequelae. The treatment of tectal plate gliomas is controversial. The role of different therapeutic options remains open. We consider the tectal plate as a relatively safer territory for surgery than the ventral part of the midbrain. The brain stem auditory evoked potentials (BAEPs) and middle latency potentials (MLPs) monitoring can help to determine the appropriate limit of surgery.
