Changes in the hand circulation in a case of pulmonary osteo-arthropathy
The circulation through the hand was investigated during release of sympathetic tone in a case of hypertrophic osteo-arthropathy. There was a great increase in hand blood flow, but only a small increase in the rate of heat elimination from the hand as compared with values obtained in normal people. This is taken to indicate a large increase in blood flow in the deeper vessels in the hand, possibly in the bony or periosteal vessels.
Following removal of a bronchial carcinoma the bone changes regressed, the hand blood flow fell to within normal limits and the rate of heat loss returned to normal.
