Aneurysms present with varying risks of rupture, and patient-specific factors influence anticipated life expectancy, operative risk, and need to intervene. Careful attention to the choice of operative strategy along with optimal treatment of medical comorbidities is critical to achieving excellent outcomes.

The SVS recommends endovascular repair as the preferred method of treatment for ruptured aneurysms.

The SVS suggests that the Vascular Quality Initiative mortality risk score (https://qxmd.com/calculate/calculator_322/vascular-quality-initiative-vqi-cardiac-risk-index-cri-evar) be used for mutual decision-making with patients considering aneurysm repair.

The SVS also suggest that elective endovascular aneurysm repair (EVAR) be limited to hospitals with a documented mortality and conversion rate to open surgical repair of ≤2% and that perform ≥10 EVAR cases each year. The SVS also suggests that elective open aneurysm repair be limited to hospitals with a documented mortality of ≤5% and that perform ≥10 open aortic operations of any type each year.

The SVS suggests a door-to-intervention time of <90 minutes, based on a framework of 30-30-30 minutes, for the management of the patient with a ruptured aneurysm.

The SVS recommends treatment of type I and III endoleaks as well as of type II endoleaks with aneurysm expansion but recommend continued surveillance of type II endoleaks not associated with aneurysm expansion.

Whereas antibiotic prophylaxis is recommended for patients with an aortic prosthesis before any dental procedure involving the manipulation of the gingival or periapical region of teeth or perforation of the oral mucosa, antibiotic prophylaxis is not recommended before respiratory tract procedures, gastrointestinal or genitourinary procedures, and dermatologic or musculoskeletal procedures unless the potential for infection exists or the patient is immunocompromised.

Increased utilization of color duplex ultarasound is suggested for postoperative surveillance after EVAR in the absence of endoleak or aneurysm expansion.
