Resumen
DUARTE-GAMAS, Luís et al. The effect of contralateral carotid occlusion in patients undergoing carotid artery endarterectomy. Angiol Cir Vasc [online]. 2022, vol.18, n.1, pp.30-35. Epub 31-Mar-2022. ISSN 1646-706X. https://doi.org/10.48750/acv.419.
Introduction:
Contralateral carotid occlusion (CCO) is considered a high-risk condition for patients undergoing carotid artery endarterectomy (CEA). Patients with a CCO may be intolerant to carotid cross-clamping during CEA, thus prone to postoperative adverse neurological outcomes. Patients with CCO may also have a higher burden of atherosclerotic disease, leading to a higher rate of cardiovascular events.
Methods:
A Medline search was performed in order to identify publications focused on the impact of CCO on outcomes after CEA.
Results:
Patients with CCO present a higher incidence of intolerance to carotid cross-clamping. The rates of shunt use are higher in patients with CCO. In the postoperative period, patients with CCO show a higher rate of stroke. Evidence regarding the effect of CCO on long-term outcomes remains controversial, with most studies reporting a lack of association between CCO and adverse long-term outcomes after CEA.
Conclusion:
Patients with CCO have an increased risk of postoperative adverse outcomes. The best strategy for this group of patients should be based on a case-by-case approach.
