Therefore, this study aimed to investigate determined independent risk factors for pain in these patients. We retrospectively collected data for 168 patients with venous malformations of the extremities from January 16, 2013 to August 13, 2015. They were categorized into painful and painless groups according to the symptom and pain scores. Associations between pain and candidate factors were determined using univariate and multivariate analyses. A total of 125 (74.4%) patients with an average pain score of 4.4 were included in the painful group. In univariate analysis, age, lesion size, tissue involvement, and phleboliths were associated with pain. In the multivariate analysis, only type-II tissue involvement (adjusted odds ratio 4.57; p = 0.001) and phleboliths (adjusted odds ratio 2.44; p = 0.039) were identified as the independent risk factors. In conclusion, this study revealed that prevalence of pain in patients with venous malformations of the extremities was high. Patients who presented with type-II tissue involvement and phleboliths are more likely to suffer from pain.<\/jats:p>","DOI":"10.1177\/1358863x18802007","type":"journal-article","created":{"date-parts":[[2018,10,20]],"date-time":"2018-10-20T01:18:41Z","timestamp":1539998321000},"page":"56-62","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":15,"title":["Risk
