title: [Sural sinus as the main source of postoperative venous thromboembolic complications in neurosurgical patients].
abstract: The authors analysed the results of diagnosis and treatment of venous thromboembolic complications in a total of 239 patients presenting with various-aetiology intracranial haemorrhage and tumours of the central system. The total incidence of venous thromboses in the system of the inferior vena cava amounted to 25.1%. Thromboembolism of pulmonary artery complicated the course of the underlying disease in 3.3% of cases. Operative treatment of the underlying disease resulted in an increased incidence rate of thromboses of deep veins from 18.5 to 36.4% (p=0.015) and that of pulmonary artery thromboembolism from 2.7 to 4.5% (p=0.5). The most frequently encountered localization of thromboses in the postoperative period turned out to be the sural veins of the crus. The level of consciousness (p=0.0001), operative treatment (p=0.002), putaminal and thalamic intracranial haematomas (p=0.01), as well as dislocation syndrome (p=0.05) according to the findings of the univariate analysis were the risk factors for the development of venous thromboses in patients with haemorrhagic stroke. Independent predictors of the development of venous thromboembolic complications in patients with haemorrhagic-type acute impairments of cerebral circulation according to the data of the univariate analysis were the level of consciousness by the Glasgow coma scale scoring 4-5 points (p=0.01) and deep-seated localization of the intracerebral haematoma (p=0.01). Patients with intracranial haematoma having endured operative treatment are a cohort of patients running the highest risk for the development of postoperative venous thromboembolic complications.
