RIVEROS DURE, César Damián et al. Frequency of neurological complications of subarachnoid hemorrhage. Rev. virtual Soc. Parag. Med. Int. [online]. 2022, vol.9, n.2, pp.113-119. ISSN 2312-3893.


The most frequent neurological complications of subarachnoid hemorrhage are cerebral vasospasm, rebleeding and hydrocephalus. The seizures that may be associated are generally secondary to these complications. Their appearance influences the morbidity and mortality of affected patients.


To determine the frequency of clinical complications of subarachnoid hemorrhage

Material and methods:

An observational, descriptive, cross-sectional, retrospective study was used. One hundred five adult patients with subarachnoid hemorrhage who attended the Hospital Nacional of Itauguá, Paraguay, in the period 2020-2021 were included.


The mean age was 52±15 years. Most of the patients were female (59.05%) and came from the Central Department. Arterial hypertension was the main comorbidity. Most of the patients presented Fisher grade 4 in the simple skull tomography and the clinical presentation was Hunt and Hess grade 2. Vasospasm was the most frequent neurological complication while mortality was 54.29%.


The Fisher grade 4 and the Hunt and Hess grade were the most frequent grades of imaging presentation and clinical involvement. The predominant neurological complication was vasospasm, isolated or associated with other complications such as hydrocephalus or rebleeding. Mortality was 54.29%.

Keywords : subarachnoid hemorrhage; intracranial vasospasm; hydrocephalus.
