Deep-vein and intracardiac thrombosis of unclear aetiology: possible association with intermittent low-voltage electrical trauma.
Extensive deep-vein thrombosis (DVT) may result from a high-voltage electrical injury. Little is known about the effects of long-term, low-voltage electrical stimulation. We report on the unusual finding of deep-vein thrombosis in a black patient, affecting the superior vena cava and right femoral vein, in association with a right atrial mural thrombus, following low-voltage electrical stimulation of the body for analgesic purposes. The patient had slightly decreased blood levels of proteins C and S, with no other known risk factors. The diagnosis, management and prognosis are discussed. This case demonstrates the need to investigate the cardiovascular effects of chronic, low-voltage electrical stimulation.
