CASE PRESENTATION A 79-year-old patient was hospitalized with staphylococcus aureus sepsis and MAA originating from the ostium of the left common carotid artery (CCA). Initial treatment consisted of high-dose antibiotics and blood pressure control. After 48 hours a CT-angiography revealed rapid growth of the MAA with imminent rupture. Various treatment options were considered: a covered stent in the left CCA, a carotid-subclavian bypass with ligation of the left CCA ostium or arch replacement, or an extra-anatomical transposition of the supra-aortic vessels with thoracic endoprosthesis. The last option was selected and, combined with six weeks of antibiotics, proved successful in controlling the impending rupture and treating the MAA. CONCLUSIONS Endovascular techniques are used if open surgery is refused, when surgical risks are prohibitively high (as definitive or palliative treatment), or as an emergency temporary treatment until definitive surgical treatment is feasible. Our high-risk patient underwent endovascular treatment for MAA as a definitive treatment. Endovascular treatment is increasingly becoming the treatment of choice due to the high morbidity and mortality of open surgical repair. Although the main concern using endovascular treatment is absence of debridement, recent studies show that combining endovascular treatment and long-term antibiotic therapy represents a potentially durable treatment and viable alternative to open surgical repair.
