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.
Objective To investigate the short and medium term results of Castor single branched stent combined with parallel stent technique in the reconstruction of supra-aortic branches in total endovascular repair of aortic arch lesions. Methods The clinical data of patients with aortic arch disease who were treated with single-branch stents combined with parallel stents for Z1 anchoring and total endovascular repair from April 2022 to August 2022 in the Department of Cardiovascular Surgery of the First Affiliated Hospital of University of Science and Technology of China were retrospectively analyzed, and the perioperative and follow-up conditions of the patients were analyzed. ResultsThere were 4 males and 1 female with an average age of 46.2±18.6 years. This study included 1 patient of thoracic aortic aneurysm and 4 patients of acute non-A non-B aortic dissection. The success rate of surgical technique was 100.0%. The operative time was 132.3±45.1 min, the immediate postoperative isolation of lesions was satisfactory, and there were no adverse events and death in perioperative period. The median follow-up time was 13 (11-15) months. During the follow-up period, all patients survived without stent displacement, type Ⅰa endoleak, parallel stent stenosis and occlusion, and no re-operation. Conclusion The short and medium term results of single branched stents combined with parallel stents in total endovascular repair of aortic arch diseases requiring Z1 anchoring is satisfactory.
