Objective To analyze the clinical effect of hybrid surgery on complex type B aortic dissection in 5 years. Methods A retrospective analysis of 47 patients with complex type B aortic dissection in the Central Hospital of Wuhan affiliated to Tongji Medical College of Huazhong University of Science and Technology from 2014 to 2017 was conducted, including 42 males and 5 females with an average age of 54.9±11.2 years. Twenty-one patients underwent the left common carotid artery to the left subclavian artery bypass (a bypass group), and 26 patients underwent the left common carotid artery to the left subclavian artery transposition (a transposition group). Results All patients accepted hybrid surgery successfully. There was no statistical difference in arterial occlusion time or intraoperative blood loss between the two groups (P＞0.05). The 5-year follow-up rate was 100.0% (47/47). During the follow-up period, 12 (25.5%) patients developed complications, including 5 (10.6%) patients of endoleak, 5 (10.6%) patients of hoarseness, 2 (4.3%) patients of stroke/dizziness. There was no patient of left upper limb weakness, paraplegia or retrograde aotic dissection. The reconstructed left subclavian artery remained patent in 46 (97.9%) patients. The overall 5-year survival rate was 100.0%. Conclusion The long-term therapeutic outcome of hybrid surgery for the treatment of complex type B aortic dissection is satisfying. In 5 years, the rebuilt left subclavian artery has a remarkable patency rate. Endoleak and hoarseness are the most common surgical complications.
