title: Colour Doppler demonstrates venous flow abnormalities in breast cancer patients with chronic arm swelling.
abstract: Chronic arm oedema following breast cancer treatment is traditionally attributed to lymphatic obstruction, with venous obstruction as an infrequent complicating factor. The axillo-subclavian venous systems of 81 patients with arm swelling following breast cancer treatment were examined with colour Doppler, duplex Doppler and grey scale ultrasound. Over half (57%) had evidence of venous outflow obstruction and a further 14% had signs of venous "congestion". Only 30% of the swollen arms had normal venous outflow. The venous systems of the contralateral non-swollen arms were all normal as were both arms in 28 control patients who had similar treatment but had not developed arm swelling. These findings suggest that venous outflow obstruction is an important contributory factor in the pathophysiology of arm swelling following breast cancer treatment.
