Abstract

Objectives

Actin, alpha-2, smooth muscle, aorta (ACTA2) mutations are one of the major causes of familial thoracic aortic aneurysms and dissections. The aim of this study was to review our clinical results of young adult patients with aortic disease caused by ACTA2 mutations.

Methods

We reviewed the medical records of 251 patients (<50 years old) who underwent surgery for thoracic aortic diseases between 2004 and 2014. Among them, nine patients (3.5%) had ACTA2 mutations. Their average age was 35 years (range 22–47) and two patients (22.2%) were males. No patients fulfilled the diagnostic criteria for Marfan syndrome. Preoperative diagnoses included annulo-aortic ectasia (n = 2), localized dissection of the sinus of Valsalva (n = 2), acute type B aortic dissection (n = 1), and chronic type B (n = 4). Eight patients (88.9%) had hypertension.

Results

A thoracoabdominal aortic replacement was required in three patients who had descending replacement for residual chronic type B aortic dissection. A patient who had thoracic endovascular aortic repair for complicated acute type B aortic dissection showed no aortic dilatation for 7 years after TEVAR. Histological results revealed cystic medial necrosis (CMN) in most cases (7/8; 87.5%).

Conclusion

Surgical outcomes for patients with ACTA2 mutations were satisfactory. CMN was a major histological finding and family history of aortic event was detected in only half of the patients with ACTA2 mutations. Despite no characteristic physical findings besides hypertension, connective tissue disease including ACTA2 mutations should be considered for aortic dissection in young adult patients.
