Does carotid endarterectomy improve the chance of survival free of (recurrent) stroke after ischemia or stroke of the brain or retina? Three studies undertaken more than 20 years ago^1-3 are still the only randomized controlled trials available, to my knowledge. These three studies, which involved 227 surgically treated and 208 control patients, are reviewed below, and their results are summarized in the Table.

In the joint study of Fields et al,¹ which involved randomized patients with carotid or vertebrobasilar ischemia (approximately 46%, vertebrobasilar ischemia only), 169 patients underwent 206 carotid and ten vertebral operations, while 147 were treated nonsurgically. The mean length of follow-up (FU) was 42 months for each group.

Table 5 of Bauer et al² describes the outcome of 78 patients with completed stroke: 38 were randomized for surgery and 40 for nonsurgical management. The FU was 24 to 42 months. ("Worsened" in Table 5 . . . [Full Text PDF of this Article]
