The Origin and Clinical Significance of Thyroid Murmur

抄録

The thyroid murmur was analyzed in respect to the various characteristics of the murmur per se, the changing aspects in the diseased state as well as the process of the therapy, and finally the pathogenesis by angiography and cast preparations of the thyroid.
1. The thyroid murmur was recorded in 37 out of 39 cases of hyperthyroidism and it was often continuous murmur with systolic accentuation. The murmur was best recorded at the isthmus of the gland, and the murmur over the right lobe was significantly louder in many cases. The reason of this localization was discussed, based on the anatomy of the vessels.
2. The intensity and duration of the murmur were well correlated with the severity of the signs and symptoms in the individual case. Thus it is concluded that the routine phonography of the thyroid gland has an important diagnostic value in the assessment of the diseased state as well as the objective judgement of the treatment.
3. Investigated by the angiography and cast preparations, the most probable origin of the thyroid murmur was mainly in the region of the arterio-venous and arterio-arterial anastomoses. The accessory importance of the other conditions, such as hyperkinetic state and the compression of the artery by the congestion of the gland, was also discussed.
