Limited data, significant morbidity, and substantial cost of wound care led us to undertake this study to describe and identify risk factors. Methods: After Institutional Review Board approval, we identified 30 patients with SSc and lower extremity ulcers over a 10-year period at a single center with an SSc clinic, which were included in a descriptive analysis. Results: Median age of onset of lower extremity ulcers was 59.5 years (range 20 - 84). Ninety percent of patients were female, 60% were Caucasian, 63% had limited SSc, 13% diffuse SSc and 23% an overlap syndrome. Immunomodulators or steroids were prescribed in 53%;hypercoagulable state identified in 16%. Ulcers were attributed to venous stasis (27%), SSc (20%), trauma (20%), arterial disease (17%), and multifactorial/unknown (17%). In patients with ulcers attributed to SSc, age at onset was lower (45.5 vs 59.5 years). Biopsies generally did not contribute to management. Multidisciplinary treatment was routine;20% required amputation, 10% endovascular intervention, 20% frequent surgical debridement, 10% hyperbaric oxygen, 26% local treatment and antibiotics and 13% received immunosuppression for wound treatment. Conclusion: Lower extremity ulcers are a serious clinical problem in patients with SSc. The clinical exam, venous dopplers, ankle-brachial indices and assessment of vascular risk factors helped define causality. In younger patients, ulcers were more frequently attributed to SSc and these patients were more likely to be on immunosuppressants/DMARDS, possibly indicating severe phenotype of SSc.展开更多
目的：研究伴或不伴有心血管病的同类下肢骨折患者下肢深静脉血栓形成（DV T ）的发生及相关情况。方法选取骨折患者584例，根据伴或不伴有冠心病和（或）高血压，将其分为伴有心血管病组235例和无心血管病组349例，心血管病组患者中，...目的：研究伴或不伴有心血管病的同类下肢骨折患者下肢深静脉血栓形成（DV T ）的发生及相关情况。方法选取骨折患者584例，根据伴或不伴有冠心病和（或）高血压，将其分为伴有心血管病组235例和无心血管病组349例，心血管病组患者中，仅伴有原发性高血压89例，仅伴有冠心病53例，同时伴有原发性高血压和冠心病93例，比较心血管病组与无心血管病组下肢DVT的发生率、骨折后不同时间段下肢DVT 的发生率，不同年龄段骨折患者DVT的发生情况。结果与无心血管病组比较，心血管病组下肢DVT发生率明显升高（22．55％ vs 12．89％，P＜0．01）。2组骨折后0～7 d下肢DVT的发生率均明显高于骨折后8～14 d及＞14 d（P＜0．01）。2组年龄≥60岁患者DV T发生率明显高于年龄＜60岁患者。结论伴有心血管病且年龄≥60岁的下肢骨折患者更易于发生下肢DVT ，骨折后1周内是其好发时间段，加强对高危人群的重视并尽早采取预防措施有可能降低骨折后下肢DVT的发生。展开更多
