“…Arterial lesions as a consequence of repeated blows are typical of the hypothenar hammer syndrome, in which the hand is used as a hammer, and the repeated blunt trauma may lead to arterial damage, thrombus formation, aneurysm of the ulnar artery or the superficial palmar arch, or microemboli formation, leading to digital ischemia. 6 Logically, therefore, Komen and colleagues 4 concluded that since atherosclerosis cannot be the pathogenic mechanism of PAU evolution in this particular patient, the shear forces of the repeated blunt trauma on the patient's chest by the pneumatic drill, in combination with the untreated hypertension, may very likely be the initiating mechanism of PAU development. Thus, they proposed calling this condition the “aortic hammer syndrome.”…”
