Midterm Survival and Quality of Life After Extent II Thoracoabdominal Aortic Repair in Marfan Syndrome

Background. Pathologic conditions of the aorta remain a major source of morbidity and mortality for patients with Marfan syndrome (MFS). Extensive thoracoabdominal aortic aneurysm (TAAA) repair can prevent aortic catastrophe but carries substantial risk of perioperative adverse events. We evaluated midterm survival and quality of life (QoL) after contemporary Crawford extent II TAAA repair in patients with MFS. Methods. From 2004 to 2010, 49 consecutive patients with MFS (mean age, 43.4 +/- 12.0 years) underwent extent II TAAA repair (41 elective and 8 urgent/emergent procedures) with intercostal reimplantation. Thirty-six patients (73%) had aorta-related symptoms, and 45 (92%) had distal aortic dissection. Operative adjuncts included cerebrospinal fluid drainage (n = 47 [96%]), left heart bypass (n = 46 [94%]), and cold renal perfusion (n = 47 [96%]). Kaplan-Meier survival analysis was performed. QoL was assessed in 24 patients with a 12-item survey (12-Item Short Form Health Survey version 2 [SF-12v2]) a median of 5.3 (interquartile range [IQR], 4.0-7.9) years postoperatively. QoL data were normalized and compared with data from the general population. Results. There were no operative deaths, strokes, paraparesis, or paraplegia. Two patients (4%) had permanent renal failure necessitating hemodialysis. The most frequent complication was vocal cord paralysis (n = 21 [43%]). Six-year Kaplan-Meier survival was 84% 6%. The 24 patients with QoL data had slightly worse physical component scores (46.0 +/- 10.6) and slightly better mental component scores (51.4 +/- 10.4) than the general population (50 10 for both scores). Conclusions. Operative treatment of extensive TAAA in patients with MFS enables excellent midterm survival and QoL. Cerebrospinal fluid drainage, left heart bypass, and cold renal perfusion probably aid in achieving excellent outcomes. (C) 2016 by The Society of Thoracic Surgeons
