  • Progress in surgical treatment of Kommerell's diverticulum

    Kommerell's diverticulum is a rare congenital abnormal aortic development. The diverticulum can occur in both left and right aortic arches, from which an aberrant subclavian artery rises to the contralateral side. Only a small number of patients with Kommerell's diverticulum present symptoms. Dysphagia, dyspnea, chest discomfort and upper extremity blood pressure difference are common in adult patients. The risk of aortic dissection or aortic aneurysm rupture is higher in such patients than that in patients with normal aorta. Early surgical intervention is recommended to improve the prognosis. Treatment options include open surgical repair, hybrid operation and total endovascular repair. The choice of surgical method depends on the specific anatomy of patients, the patients' state and the preference of surgeons. This paper reviewed and summarized the surgical methods and early results of the treatment of Kommerell's diverticulum reported in the literature from 2015 to 2020.

  • Short- and medium-term efficacy of combining the reconstruction of left subclavian artery with thoracic endovascular aortic repair to treat Stanford type B aortic dissection

    Objective To analyze the clinical efficacy of left subclavian artery (LSA) revascularization combined with thoracic endovascular repair (TEVAR) in the treatment of Stanford type B aortic dissection (AD). MethodsA retrospective analysis was conducted on patients treated with TEVAR combined with LAS reconstruction surgery at Wuhan Central Hospital in Hubei Province from 2017 to 2021. The patients were divided into a reconstruction group and a simple stent group. The reconstruction group was subdivided into a hybrid reconstruction group and a chimney reconstruction group according to the different methods of reconstruction surgery. Perioperative data of different groups were compared. A total of 144 patients were included, including 108 males and 36 females. There were 113 patients in the simple group and 31 patients in the reconstruction group. There were statistically significant differences in surgical time, hospital stay, preoperative lesion area diameter, and postoperative right vertebral artery diameter between the reconstruction group and the simple group (P<0.05). There was no statistically significant difference in postoperative complications between the simple group and the reconstruction group within 1 year (P>0.05). There was no statistically significant difference in surgical time between different surgical procedures in the reconstruction group (P>0.05). During the follow-up period, there were no deaths. A total of 12 (10.6%) patients in the simple group experienced complications, which was lower than that in the reconstruction group (8 patients, 25.8%). Among them, the most common complication in the follow-up of patients in the simple group was internal leakage (5 patients), and there was no statistical difference compared to patients in the reconstruction group (2 patients). The most common complication in the follow-up of patients in the reconstruction group was hoarseness (2 patients), while in the simple group, 1 patient occurred. Conclusion Both different surgeries have good effects on the treatment of type B aortic dissection, and multi center, large sample, and long-term studies are needed.

  • Analysis of 5-year follow-up results of hybrid surgery for complex type B aortic dissection

    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.

  • Efficacy of typeⅡ hybrid versus Sun’s operation in the treatment of acute Stanford type A aortic dissection: A retrospective cohort study in a single center

    ObjectiveTo compare the clinical efficacy of TypeⅡhybrid and Sun’s surgery in treating acute Stanford A aortic dissection. MethodsA retrospective analysis was conducted on the clinical data of patients with acute Stanford A aortic dissection who were treated at the Central Hospital of Wuhan affiliated to Tongji Medical College, Huazhong University of Science and Technology from 2016 to 2022. According to the surgical method, patients were divided into a typeⅡhybrid group and a Sun’s surgery group, and the clinical efficacy of the two groups was compared. ResultsA total of 52 patients were included, with 22 in the typeⅡhybrid group and 30 in the Sun’s surgery group. The typeⅡhybrid group consisted of 18 males and 4 females, with an average age of (58.18±6.00) years, while the Sun’s surgery group consisted of 22 males and 8 females, with an average age of (53.03±11.89) years. All surgeries were successfully completed. There were 4 (13.3%) perioperative deaths in the Sun’s surgery group, including 2 patients of multiple organ failure, 1 patient of paraplegia, and 1 patient of uncontrollable postoperative bleeding. There was 1 (4.5%) perioperative death in the typeⅡ hybrid surgery group, who was suspected of acute coronary syndrome and took a loading dose of dual antiplatelet drugs preoperatively. The patient underwent secondary thoracotomy for hemostasis, was re-cannulated during the operation, and finally died of circulatory failure after implantation of intra-aortic balloon pumping. There was no statistical difference in perioperative mortality between the two groups (P=0.381). Compared with the Sun’s surgery group, the typeⅡhybrid surgery group had shorter cardiopulmonary bypass time [153.00 (135.00, 185.25) min vs. 182.50 (166.50, 196.75) min, P=0.013], aortic cross-clamp time [77.00 (70.50, 92.00) min vs. 102.50 (93.50-109.75) min, P<0.001], postoperative ICU stay [4.0 (2.83, 6.00) days vs. 8.0 (6.38, 11.78) days, P<0.001], postoperative ventilator support time [72.00 (29.50, 93.25) h vs. 87.65 (39.13, 139.13) h, P=0.138], intraoperative blood loss [(1586.82±209.41) mL vs. (1806±292.62) mL, P=0.004], postoperative 24 h drainage volume [612.50 (507.50, 762.50) mL vs. 687.50 (518.75, 993.75) mL, P=0.409], and postoperative hospital stay [18.00 (13.00, 20.25) days vs. 22.00 (17.00, 29.25) days, P=0.013]. There was no statistically significant difference in the incidence of other early postoperative complications such as secondary thoracotomy for hemostasis, tracheotomy, renal dysfunction requiring dialysis, stroke, and paraplegia between the two groups (P>0.05). ConclusionFor patients with acute Stanford A aortic dissection, typeⅡhybrid surgery is safe and effective; compared with traditional Sun’s surgery, typeⅡ hybrid surgery has relatively less trauma, lower incidence of complications, satisfactory short-term results, and further research is needed on long-term prognosis.
