[Significance of arterial Doppler in Horton's disease. Prospective study of 59 case reports].
Several preliminary studies drew attention to the value of Doppler examination in temporal arteritis. This study involving 59 cases aimed to define the value of Doppler examination in the diagnosis of the disease, evaluation of ophthalmic risk and in the monitoring of treatment. The study involved 59 patients and 47 controls with no evidence of temporal arteritis, but of comparable mean age. The following arteries were investigated before treatment: arteries of limbs, subclavian, vertebral, carotid, temporal, occipital, facial and ophthalmic recorded via the internal nasal branch and also transocularly. The results were expressed in the form of a score from 0 to 3 describing the degree of deterioration of the curves. A mean score corresponding to the mean of the scores of the cephalic arteries was calculated for each patient and each control. The specificity and sensitivity of the investigation were studied, based on this mean score by ROC analysis. The progression under treatment was monitored for more than 24 months in 20 patients divided into 3 groups: group I: 6 patients cured; group II: 6 patients with late recurrence of temporal arteritis after steroid withdrawal; group III: 8 patients with progressive disease. 81.5% of temporal arteries were pathological, including 60% with tight stenosis (score 2 and 3). Morphological anomalies in the curves were also noted at the level of the occipital arteries (69%), facial arteries (80%), as well as the ophthalmic artery at both recording sites (internal nasal: 84.5%, transocular: (73%) (table I).(ABSTRACT TRUNCATED AT 250 WORDS)
