Carotid artery shortening: a safe adjunct to carotid endarterectomy.
OBJECTIVE
Kinks and coils of the extracranial carotid artery system have been described in conjunction with atherosclerotic disease of the internal carotid artery. The purpose of this study was to determine whether adding a carotid artery shortening procedure to carotid endarterectomy affected perioperative mortality and stroke-morbidity rates or late restenosis.


METHODS
A retrospective chart review of all patients who concurrently underwent carotid endarterectomy and ipsilateral carotid artery shortening between 1983 and 1992 was performed. Long-term follow-up was obtained by contacting the primary physician or patient, and carotid artery duplex scans were obtained.


RESULTS
One hundred seven patients were found to have undergone concurrent carotid endarterectomy and carotid artery shortening. The age range was 47 to 89 years, with 53 female and 54 male patients. Indications for surgery in this group were transient ischemic attacks in 28%, stroke in 18%, amaurosis fugax in 7%, and high-grade asymptomatic stenosis in 47%. Shortening procedures were performed by use of a variety of techniques at the completion of endarterectomy. The combined 30-day mortality and stroke morbidity rate was 2.7%, with two postoperative deaths and one stroke. In this same period, a total of 1072 carotid endarterectomies were performed, and the combined 30-day mortality and stroke morbidity rate was 4.0%. During late follow-up there were no ipsilateral strokes, recurrent symptoms, or significant restenoses.


CONCLUSIONS
This experience suggests that the addition of a shortening procedure to carotid endarterectomy can be performed without increased morbidity and mortality rates and, when deemed appropriate, is a procedure with which the vascular surgeon should be familiar.
