Risk factors of pulmonary thromboembolism in patients from a university hospital

Objective: To investigate the impact of risk factors in the diagnosis of pulmonary thromboembolism. Methods: This was a retrospective study of 295 patients with suspicion of pulmonary embolism (PE), of whom 154 were referred from outpatient and 141 from inpatient departments for a period of 24 months (2000-2001) in Hacettepe University Hospital in Amkara. Results: Pulmonary thromboembolism was diagnosed in 71 patients (24.1%) with high probability ventilation/ perfusion scintigraphy. Chronic renal failure, trauma, history of pulmonary thromboembolism and type of care were significantly associated with pulmonary thromboembolism, after adjusting for age and gender. Condasion: This retrospective study revealed that clinicians should keep PTE in mind, especially in the presence of risk factors. Ventilation/perfusion scintigraphy has been the procedure of choice for the assessment of patients with suspected PE.
