A. Tamasauskas et al., Management of patients with ruptured cerebral aneurysms in hospital population of Lithuania, ACT NEUROCH, 142(1), 2000, pp. 51-59
A retrospective analysis of ruptured cerebral aneurysms among the hospital
population of Lithuania was performed. A total of 507 patients were enrolle
d in the study during a 5 year period. The unadjusted annual incidence of r
uptured cerebral aneurysms was found to be 2.7/100,000 in the hospital popu
lation of Lithuania and 3.9/100,000 in the hospital population of the defin
ed area of the city of Kaunas. Overall management results showed a 45.6% go
od recovery and 31.6% death rate in this group of patients. Surgical result
s showed a 52.1% good outcome and 20.9% death rate. Despite the fact that t
he death rate according to the timing of surgery after the initial subarach
noid haemorrhage did not differ significantly (p > 0.05) among early (0-3 d
ays post SAH), moderate (4-7 days post SAH) and late (more than 7 days post
SAH) surgery groups, it was found that 75 (14.8%) patients deteriorated wh
ile awaiting surgery. Initial bleeding together with rebleeding, medical co
mplications and vasospasm were the main causes of death, constituting 61.3%
, 18.1% and 9.4% of all deaths, respectively.
The results of this study showed that the annual incidence of ruptured cere
bral aneurysms in Lithuania is similar to that in other European countries
except for Finland. Overall management results in the Lithuanian hospital p
opulation indicated only a slight improvement compared to management result
s of previous population-based studies in other countries.
