Routine completion angiography during carotid endarterectomy is not mandatory.
OBJECTIVE
Intraoperative quality control after carotid endarterectomy (CEA) has been advocated to improve the results of surgical treatment of extracranial carotid artery disease. The aim of this study was to evaluate the usefulness of completion angiography (CA) in prevention of stroke and restenosis after CEA in a single center experience.


METHODS
Data concerning 914 consecutive CEAs performed in 3 years (2000-2002) were prospectively collected in a dedicated database. Patients were divided into two groups: in the first group (mandatory-CA group; 430 cases) CA was routinely carried out, except in presence of contraindications to iodinate contrast agents; in the second group (selective-CA group, 484 cases) CA was performed only in selected cases, at surgeon's discretion.


RESULTS
There were no significant differences between the two groups in terms of neurological complications at awakening (0.5% in mandatory-CA group and 0.4% in selective-CA group; p=n.s.) and in 30-day stroke and death rate (1.9% and 1.4%, respectively; p=n.s.). A surgical revision on the basis of CA findings was performed in 5 cases in mandatory-CA group and in 2 cases in selective-CA group (1.2% and 0.4%, respectively; p=n.s.). In the second group, the conditions significantly associated with the need for CA examination were internal carotid near-occlusion, preoperative symptoms, shunt insertion, kind of surgical reconstruction, redo surgery. Estimated absence of ipsilateral stroke and absence of restenosis at 18 months was 98.9% and 89.7% in mandatory-CA group and 99.3% and 93.4% in selective-CA group (p=n.s.) respectively.


CONCLUSIONS
Based on our experience, routine CA following CEA is not suggested. A policy of selected CA at the surgeon's discretion seems to make the intervention safe and durable as well.
