Evaluation of the diagnostic contribution of color coded duplex sonography (CCDS) of the superficial temporal (STA) and the occipital artery (OCCA) in biopsy-controlled patients suspected of having temporal arteritis (TA).
Prospective study in 67 patients suspected of having TA who underwent CCDS of the STA in all cases and the occipital arteries if involvement of the OCCA was suspected clinically. The final diagnosis, based on biopsy results in 67 cases and standard criteria, were compared to the ultrasonographic findings to determine their diagnostic contribution.
TA was diagnosed in 40 patients, other diseases in 27 patients. In the STA periarterial hypoechogenic tissue, the so-called halo, halo and stenoses, and occlusions were found in 83% of TA patients and 11% of patients with other diseases. In the OCCA, these abnormalities were found in 65% of TA patients and in no patient with other diseases. Taking both STA and OCCA together, halo, stenosis, and widespread abnormalities were found in patients with TA, but not in patients with other diseases.
CCDS of the STA and OCCA clearly contributes to the diagnosis of TA, with a high rate of perivascular hypoechogenic abnormalities (so-called halos) and stenosis and a low rate of these abnormalities in the control patients. However, CCDS cannot differentiate between inflammatory and degenerative artery disease and has spatial resolution limitations.
评估彩色编码双功超声（CCDS）对颞浅动脉（STA）和枕动脉（OCCA）检查在活检确诊的疑似颞动脉炎（TA）患者中的诊断价值。
对67例疑似TA患者进行前瞻性研究，所有患者均接受STA的CCDS检查，若临床怀疑OCCA受累，则同时检查枕动脉。将基于67例活检结果和标准标准得出的最终诊断与超声检查结果进行比较，以确定其诊断价值。
40例患者诊断为TA，27例患者诊断为其他疾病。在STA周围动脉低回声组织（即所谓的晕）、晕及狭窄和闭塞方面，83%的TA患者及11%的其他疾病患者有此类表现。在OCCA，65%的TA患者有这些异常表现，而其他疾病患者均无。综合STA和OCCA检查结果，TA患者存在晕、狭窄及广泛异常，而其他疾病患者无此表现。
STA和OCCA的CCDS对TA的诊断有明显帮助，血管周围低回声异常（所谓的晕）及狭窄发生率高，而对照患者中此类异常发生率低。然而，CCDS无法区分炎症性和退行性动脉疾病，且存在空间分辨率限制。
