Abstract
BACKGROUND: Endovascular repair is now preferred to open access for the management of aortic diseases. This is typically performed via the femoral artery; however, not all patients are eligible for this. This systematic review summarizes the current evidence for utilizing the carotid artery as an alternative access route. METHODS: A systematic review was conducted as per the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines using 4 electronic databases. RESULTS: The search found 11 case reports representing 12 patients eligible for analysis (mean age 64.5 years). This included 3 thoracic aneurysms, 3 abdominal aneurysms, 4 penetrating ulcers, 1 endoleak, and 1 pseudoaneurysm. An open procedure was contraindicated in 83% (10/12) due to the poor physiological fitness of the patient. In 75% (9/12) of cases, traditional endovascular access was contraindicated by severe iliac disease. The remainder were contraindicated because of an existing ligated aortic stump (1/12, 8.3%) or technical difficulty with graft deployment via the femoral artery (2/12, 16.7%). There was 1 death, with the 30-day mortality 8.3%. The same patient suffered the only spinal ischemia before death (8.3%). There were no cases of stroke (0%), with one case of transient ischemic attack (8.3%). CONCLUSIONS: Although there is a relative paucity of literature, this study demonstrates when traditional endovascular access is impossible and an open procedure contraindicated, carotid artery access for endovascular repair of aortic pathology is a viable alternative with good 30-day survival and low rates of neurological sequelae.
