Introduction: Post-thrombotic syndrome is a frequent and disabling complication of deep venous thrombosis. Its incidence is not described in the Portuguese population. The objective of this study is to report the incidence and severity of post-thrombotic syndrome after the initial episode of deep venous thrombosis., Material and Methods: This is an observational, unicentric, retrospective cohort of patients who had a first episode of deep venous thrombosis in the lower limb, documented with duplex ultrasound (n = 101). The modified Villalta score was applied by phone interview for the diagnosis and staging of post-thrombotic syndrome. The quality of life of patients was measured with the modified CIVIQ 14 classification., Results: Median follow-up time was six years (interquartile range 1). Severe post-thrombotic syndrome was present in 27% of patients and moderate in 33%. Performing physical activity at the time of the interview was associated with lower incidence of post-thrombotic syndrome (relative risk 0.489; 95% confidence interval = 0.320 - 0.748). Body weight gain after deep venous thrombosis (relative risk 2.188; 95% confidence interval 1.137 - 4.210) and lower education levels (relative risk 2.005; 95% confidence interval 1.297 - 3.098) were associated positively with post-thrombotic syndrome. Quality of life was 90 ± 17 vs 64 ± 18 vs 43 ± 15 in patients without postthrombotic syndrome, with moderate post-thrombotic syndrome and with severe post-thrombotic syndrome, respectively (p < 0.001)., Discussion: The long-term incidence of post-thrombotic syndrome in a cohort of patients from Northern Portugal is higher than in other studies and correlates with worse adjusted CIVIQ-14 scores., Conclusion: Large studies of prospective nature could provide more definitive evidence.

Background: The incidence of abdominal aortic aneurysm (AAA) repairs in Portugal is one of the lowest mentioned in the literature. This phenomenon can be justified either by a low prevalence of the disease or by its low detection rate. To date, the prevalence of the pathology is unknown. The objective of the study was to estimate the prevalence of AAA and its associated risk factors, in men aged ≥65 years and to evaluate the population's disease awareness., Methods: All males aged ≥65 years registered in a Portuguese primary health care unit were invited to participate. The abdominal aorta was measured by ultrasound (inner to inner method). Concomitant risk factors and patient's AAA awareness were also assessed. An aortic diameter >30 mm was considered aneurysmatic., Results: Nine hundred thirty-three patients were invited for the screening. Of these, 715 participated in the study (participation rate of 76.6%). The AAA prevalence in this sample was 2.1%. Eighty-five percent of the evaluated patients had never heard of the disease before. The mean age of the assessed population was 72.3 years; Multiple logistic regression analysis showed a positive association between AAA and history of smoking (odds ratio [OR] 8.8, P = 0.037) and history of dyslipidemia (OR 9.6, P = 0.035). A negative association was found between diabetes and AAA (OR 0.33, P = 0.045)., Conclusions: The found prevalence shows that a significant number of potentially fatal AAAs remains to be diagnosed in Portugal. These results highlight the need for an effective program of AAA detection in Portugal. The lack of awareness in the Portuguese population for this pathology should also prompt reflexion., (Copyright © 2019 Elsevier Inc. All rights reserved.)
