Subclavian artery aneurysms, occasionally related to connective tissue diseases, including Marfan syndrome, are rare and conventionally managed with surgery or endovascular treatment. However, in some cases, both interventions are challenging because of the inability to reach an aneurysm through a safe route or postoperative adhesion. This report describes the case of a 43-year-old patient with a left subclavian artery aneurysm and Marfan syndrome. In this case, the patient's 5 previous surgeries related to Marfan syndrome made surgery and endovascular treatment difficult. Therefore, an alternative was researched, and we decided to perform a method of percutaneous embolization with coils and N-butyl cyanoacrylate using the direct puncture technique, which succeeded in eliminating the blood flow in the left subclavian artery aneurysm. No severe complications were associated with the procedure. The patient was free from the risk of an aneurysm rupture post-treatment, and the left back pain improved. Follow-up computed tomography 2 years postsurgery revealed the aneurysm being under control without re-enlarging. Our method is considered an effective and safe therapeutic option for cases in which surgical approach and transarterial access routes are limited.
