A high prevalence of neovascularity in lower extremity tendinopathies has been reported. Neovascularity in those with rotator cuff tendinopathy exclusively has not been examined. The objective was to determine the prevalence of neovascularization in patients with rotator cuff tendinopathy compared with asymptomatic controls.
Single-blind cross-sectional study.
Research laboratory.
Participants (n = 40; age = 44.9 years, 23-62 years; 20 females) with rotator cuff tendinopathy (n = 20) but without full-thickness rotator cuff tears, and asymptomatic controls that were age, gender, and hand dominance matched (n = 20) to the patients.
The participants laying in supine had their shoulder positioned in internal rotation and extension. Ultrasound images were collected of the supraspinatus tendon and subacromial bursae in the transverse and longitudinal planes using a linear transducer in color Doppler mode.
Images were assessed for neovascularization by 2 trained raters who were blinded to group (rotator cuff tendinopathy or asymptomatic group).
No statistically significant difference in neovascularization was identified between participants with and without rotator cuff tendinopathy (χ = 0.13, df = 1, P = 0.72). Neovascularization was identified in 6 of 20 patients with rotator cuff tendinopathy (30%) and 5 of 20 asymptomatic control participants (25%).
The authors found no differences in neovascularization rate in patients with rotator cuff tendinopathy (30%) and asymptomatic controls (25%). The study indicates that neovascularization is not related to presence of symptomatic tendinopathy in those with rotator cuff tendinopathy. Neovascularization may not be a relevant sonographic finding to aid the clinical assessment of those with rotator cuff tendinopathy.
已有报道称，下肢肌腱病中存在较高的新生血管形成。尚未检查那些肩袖肌腱病患者中是否存在单纯的新生血管形成。本研究的目的是确定与无症状对照组相比，肩袖肌腱病患者的新生血管形成的患病率。
单盲横断面研究。
研究实验室。
参与者（n = 40；年龄 = 44.9 岁，23-62 岁；20 名女性）患有肩袖肌腱病（n = 20）但没有全层肩袖撕裂，以及与患者年龄、性别和手优势匹配的无症状对照组（n = 20）。
参与者仰卧位，肩部处于内旋和伸展位。使用线性探头以彩色多普勒模式在横切和纵切平面上采集肩袖肌腱和肩峰下囊的超声图像。
由 2 名受过培训的评估者评估图像是否存在新生血管形成，评估者对组（肩袖肌腱病或无症状组）不知情。
有和没有肩袖肌腱病的参与者之间的新生血管形成无统计学显著差异（χ = 0.13，df = 1，P = 0.72）。肩袖肌腱病患者中有 6 名（30%）和无症状对照组参与者中有 5 名（25%）存在新生血管形成。
作者发现肩袖肌腱病患者（30%）和无症状对照组（25%）的新生血管形成率没有差异。该研究表明，在肩袖肌腱病患者中，新生血管形成与症状性肌腱病的存在无关。新生血管形成可能不是评估肩袖肌腱病患者的临床评估的一个相关超声发现。
