The authors report their experience from 1985 to 1988 with 75 consecutive @entity1 affected by bilateral @entity543 in whom only one side was surgically treated and the other had a minor (15-45%) asymptomatic @entity543 . These @entity1 have been followed for a period ranging from 10 to 50 months (mean follow-up 21 months) by clinical examinations and non-invasive investigations (Doppler CW, Duplex scanner). The non-invasive evaluation included assessment of haemodynamic data and characterisation of plaque morphology (regular vs. irregular or ulcerated surface, homogeneous vs. heterogeneous plaque). During follow-up eight @entity1 died: two (2.6%) from acute @entity583 , four from @entity64 (5.3%), and two (2.6%) from other causes. Twenty-five @entity1 (33.3%) had @entity16 related to the unoperated side: and four @entity64 (5.3%). Twenty-one @entity1 had @entity4905 (28%) related to the observed side. During follow-up five out of 29 (17.2%) homogeneous and 20 out of 46 (43.4%) heterogeneous plaques progressed (p less than 0.01). With regard to the surface characteristics, nine out of 25 regular plaques progressed and only three @entity1 (12%) had neurological events; 19 out of 34 (55.9%) irregular plaques showed a progression and 14 caused @entity16 . Fourteen ulcerated plaques (87.5%) progressed (p less than 0.01). Our experience suggests that the basic trend in the follow-up of @entity1 with bilateral @entity2998 , is that the contralateral unoperated lesion may evolve and become symptomatic. These symptoms are generally @entity4905 but five @entity1 (4.3%) suffered from strokes related to the unoperated side, all without warning @entity4905 .

Minor asymptomatic XXXX contralateral to carotid endarterectomy (CEA): our experience.
