The management of the ruptured intracranial aneurysm is studied in two consecutive series: an earlier series, including 328 patients admitted from 1972 through 1984, for which the general attitude was delayed surgery, and a later 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, according to 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 SAH (D0-3, D4-6, D7-15, D16 and over). The most favourable outcome was observed for those patients admitted late (after D7) and already stabilized. Patients admitted early (D0-3) were operated on at four intervals of time (D0-3, D4-6, D7-15, D16 and over). The most favourable outcome was observed for those patients operated on early (D0-3) or very late (D16 and over). For patients admitted early and being under 50 years of age, the results were: satisfactory 92%, poor 2.5%, death 5%. The relationship between age and outcome shows a very small difference between patients under or over 50 years of age. The relationship between level of consciousness and outcome still demonstrates an appreciable difference: plus 22% (satisfactory) and minus 7% (death) in favour of alert patients. Rebleeding was the cause of disability or death in 2.8% of the overall later series and 2.7% of patients admitted early; as for vasospasm the figures are respectively 4.2% and 5.4%. These results are presented with reference to those of the Co-operative Study. After this experience, the author's general attitude for the timing of surgery is neither systematic early surgery, nor systematic delayed surgery, but modulated surgery, based upon the evaluation of the operative risk: minor risk, major risk, intermediate risk.(ABSTRACT TRUNCATED AT 400 WORDS)

The timing of surgery for the ruptured aneurysm (SAH) remains controversial. After the period of delayed surgery, the early surgery is now more and more frequently advocated. This paper, study our experience in aneurysm surgery in two different periods, considering only patients admitted in grades I to IV, excluding grade V patients (deep coma, decerebration). During the former period (1972-1984) 328 patients were admitted and considered for delayed surgery, usually during the second week following SAH. 94.5% of patients were operated upon. 5.5% patients died before surgery, from ischemia (3%) or from rebleeding (2.5%). 38.5% were admitted between (D.O-D3) after SAH, D.O being the day of SAH. Only 5.7% were operated upon between D.O-D3. The higher peak of surgery was during the second week (41.8%) and during the third week (39.2%). During the later period (1985-1988) 106 patients were admitted, 50% of them between D.O and D3 after SAH. Every patient was operated upon. The patients admitted between D.O and D3 were operated upon as follows: between D.O and D3 = 32.1%, between D4 and D6 = 22.6%, between D7 and D15 = 34%, after D16 = 11.3%. The analysis of these sub-groups demonstrates that the distribution was related to the age and clinical status. Patients being awake and under 50 years of age were considered for early surgery. Patients being obnubilated or stuporous, and over 50 years of age were planned for delayed surgery. Angiographic spasm and extension of blood in CT Scan were taken in consideration to a lesser degree.(ABSTRACT TRUNCATED AT 250 WORDS)

The International Cooperative Study on the Timing of Aneurysm Surgery included 68 participating centers from 16 different countries. Eight Italian neurosurgical units participated in the Study: Bellaria Hospital, Bologna; Neurological Institute of Milan, Milan; University Hospital, Brescia; University of Milan, Milan; University of Padova, Padova; University of Rome, Rome; Civil Hospital, Verona; and Civil Hospital, Vicenza. The overall case contribution from the Italian centers was 485 cases, 14.1% of the total study population. As compared to the other centers included in the Study, the Italian centers exhibited a higher percentage of patients with impaired consciousness; a later interval of planned surgery from SAH; frequent use of preoperative lumbar drainage, as well as antihypertensives, anticonvulsants, antifibrinolytics, steroids, diuretics and LMW dextran; and less frequent use of sedatives and narcotics. The individual Italian centers differed significantly in regard to patient characteristics and preoperative therapeutic modalities. There was a relatively high number of stuporous or comatose patients admitted to Centers 1, 7 and 8, very few admitted to Centers 5 and 6, and none admitted to Center 2. The different distribution of key prognostic factors prevents a direct comparison of the overall management results of the centers. A stratification of the patients according to a risk scale and/or a prognostic model is required for comparison of the management results.

A 17-year-old female in a lethargic state with mild dysarthria was transferred to our hospital after experiencing a generalized tonic seizure immediately after giving birth. Head CT showed a cortical subarachnoid hemorrhage(cSAH)in the left frontoparietal convexity. Three-dimensional rotational angiography(3D-RA)revealed multifocal narrowing of the cortical branches of the left middle cerebral artery(MCA)and severe stenosis of the left M1 segment with plexiform collateral networks, suggesting the presence of reversible vasoconstriction syndrome(RCVS)and aplastic or twig-like MCA(Ap/T-MCA). When 3D-RA was repeated on day 17, the narrowing of the cortical artery had resolved, and a new constriction of more proximal blood vessels was observed. The arterial spasm disappeared within 3 months, confirming the diagnosis of RCVS and Ap/T-MCA. Although non-aneurysmal SAH due to Ap/T-MCA is extremely rare, RCVS often complicates cSAH in the frontal/parietal region. It is suggested that RCVS triggers cSAH in the presence of incidental Ap/T-MCA. Ap/T-MCA is thought to be caused by developmental abnormalities during the embryonic period, but only 11 cases in children or adolescents have been reported. This suggests that there are a considerable number of asymptomatic young patients whose condition has not been detected. The majority of patients with Ap/T-MCA are from East Asia, suggesting that racial and genetic background differences are a factor. As this anomaly is more likely to present as a stroke in adulthood, long-term follow-up is recommended if it is found at a young age. There is no evidence that revascularization is effective in preventing stroke. Further studies are needed on how to manage this condition appropriately.
