Objective To investigate the short and medium term results of Castor single branched stent combined with parallel stent technique in the reconstruction of two supra-aortic branches in total endovascular repair of aortic arch lesions. Methods The 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 included, and the perioperative and follow-up data 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 aortic arch 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 follow-up time was 12-15 months. During the follow-up period, all patients survived without stent displacement, type Ⅰa endoleak, parallel stent stenosis and occlusion, or 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.
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.
ObjectiveTo summarize our experience and clinical effect of surgical treatment of Stanford type A aortic dissection (TAAD) involving an aberrant right subclavian artery (ARSA). MethodsFrom March 2009 to January 2016, 14 patients with TAAD involving an ARSA (acute TAAD, n=10; chronic TAAD, n=4) underwent operation under hypothermic cardiopulmonary bypass combined with selective antegrade cerebral perfusion in our center. There were 11 male and 3 female patients with a mean age of 46.07±8.45 years. A total of 13 patients (13/14, 92.86%) underwent stented elephant trunk procedure combined with total arch replacement (Sun's procedure). The remaining patient (1/14, 7.14%) underwent partial aortic arch replacement combined with Bentall procedure without ARSA revascularization. ResultsThe average operation time, cardiopulmonary bypass time, aortic cross-clamping time and selective cerebral perfusion time was 7.89±1.80 h, 208.43±28.84 min, 117.64±23.30 min, and 30.50±10.15 min, respectively. No operation-related deaths occurred. However, two (14.29%) patients died on postoperative 5 d, 7 d, respectively in hospital. One patient required repeat thoracotomy for bleeding, one suffered temporary renal dysfunction and one renal failure (this patient had renal failure before surgery). The mean follow-up was 28.42±22.52 months with a follow-up rate of 100.00% (12/12). One patient died of heart failure and renal failure at 64 months after operation. The others were free from any aortic complications during follow-up. ConclusionsTAAD involving an ARSA should be clearly diagnosed before surgery, and treated by the optimal arterial cannulation and cerebral perfusion during operation. Repair of aortic dissection with Sun's procedure and revascularization of the ARSA can obtain satisfactory clinical outcomes in patients with TAAD involving an ARSA.
ObjectiveTo analyze the effectiveness of in vitro fenestration versus bypass surgery techniques in the treatment of type B aortic dissection involving the left subclavian artery by thoracic endovascular aortic repair (TEVAR).MethodsAmong the 53 patients with type B aortic dissection involving the left subclavian artery admitted to our center from January 2017 to October 2020, 23 underwent in vitro fenestration + TEVAR (a fenestration group with 18 males and 5 females aged 53.6±5.3 years), and 30 patients underwent left common carotid artery-left subclavian artery bypass + TEVAR (a bypass group with 24 males and 6 females aged 51.8±3.8 years). The effectiveness and safety between the two groups were compared.ResultsThe surgical success rate was 100.0% in both groups. And there was no death within postoperative 30 days and during the follow-up. There was no endoleak immediately postoperatively and during 1-year follow-up in the two groups. The operation time and hospitalization expenses in the fenestration group was less or shorter than those in the bypass group (P<0.05). The reduction in blood pressure of the left upper limb in the fenestration group was greater than that in the bypass group (P<0.05). There was no symptom of left upper limb ischemia, dizziness or hoarseness in both groups.ConclusionThe two methods of reconstruction of the left subclavian artery are safe and effective. In vitro fenestration can reduce surgical trauma and costs, and bypass surgery can provide better forward blood flow for the left subclavian artery.
ObjectiveTo investigate the best anatomical classification, surgical timing, procedure and clinical outcomes of congenital vascular ring.MethodsThe clinical data of 58 patients who underwent congenital vascular ring surgery in Pediatric Surgery Center, Fuwai Hospital between 2014 and 2019 were retrospectively analyzed. There were 32 (55.2%) males and 26 (44.8%) females with a median age of 16.5 (2-73) months. Preoperative symptoms, imaging examinations, anatomical classifications, surgical procedures and postoperative recovery were assessed.ResultsThere were 20 (34.5%) patients of double aortic arch, 22 (37.9%) patients of right aortic arch with left arterial duct or ligament, 15 (25.9%) patients of left aortic arch with aberrant right subclavian artery, and 1 (1.7%) patient of circumflex aorta with cervical aorta arch. The median ventilator supporting time was 6.0 (0-648) h, and the median hospital stay time was 14.5 (7-104) d. One patient with coarctation of aorta died of severe pulmonary infection during perioperative period, and the others survived without symptoms and reoperation after discharge. The median follow-up time was 7.0 (1-62) months.ConclusionFor children with unexplained dyspnea and dysphagia, or with right aortic arch, preoperative imaging examinations such as computed tomography or magnetic resonance imaging are required to confirm the diagnosis of vascular ring. Surgical correction of congenital vascular ring is safe and reliable, and can effectively relieve symptoms. The mortality rate and reoperation rate are low, and the follow-up results are satisfactory.
ObjectiveTo evaluate the early and mid-term safety of transcatheter aortic valve replacement via transfemoral (TF), transapical (TAp) and transsubclavian (TSc) approaches by meta-analysis.MethodsWe systematically searched the clinical comparative trials published from inception to June 2019 from PubMed, Web of Science, EMbase and The Cochrane Library, to evaluate the safety of transcatheter aortic valve replacement through TF, TAp or TSc approaches. The information of all-cause mortality at 30 days, 1 year, 2 years and the incidence of common complications at 30 days after operation (including pacemaker-dependent block, major vascular complications, severe bleeding events, acute renal injury and stroke) were exacted, and a meta-analysis was conducted by RevMan 5.3 software.ResultsThis study included 11 literatures, with a total of 7 833 patients, among whom 5 348 patients were treated by TF TAVR, 1 796 patients by TAp TAVR and 689 patients by TSc TAVR. The results of the meta-analysis were as follows: (1) at 30 days after operation, the mortality of TF and TSc approaches were lower than that of the TAp approach (TF vs. TAp: OR=0.57, 95%CI 0.39-0.84, P=0.004; TSc vs. TAp: OR=4.12, 95%CI 1.93-8.79, P=0.000 3). There was no statistical difference between the TF and TSc approaches (TF vs. TSc: OR=0.98, 95%CI 0.38-2.51, P=0.97); at 1 year, there was no statistical difference in mortality among the three approaches (P>0.05); at 2 years, there was no statistical difference between TSc and TF or TAp approaches (TF vs. TSc: OR=1.21, 95%CI 0.95-1.54, P=0.13; TSc vs. TAp: OR=1.02, 95%CI 0.76-1.36, P=0.91). (2) The incidence of acute kidney injury after TF approach was lower than that of the TAp approach (OR=0.30, 95%CI 0.22-0.41, P<0.000 01). (3) There was no statistical difference in major vascular complications between TSc and TF or TAp approaches (TF vs. TSc: OR=0.75, 95%CI 0.38-1.49, P=0.41; TSc vs. TAp: OR=1.37, 95%CI 0.56-3.32, P=0.49). (4) There was no statistical difference in severe bleeding events between TF and TSc (OR=0.97, 95%CI 0.53-1.76, P=0.92). (5) There was no statistical difference in the incidence of postoperative stroke, pacemaker dependent block among the three approaches (P>0.05).ConclusionTAp and TSc approaches are safe and effective. They are not only an alternative to TF approach, but also the first choice in some patients with poor condition of iliofemoral artery.
ObjectiveTo investigate the effect of in vitro fenestration on reconstruction of left subclavian artery in endovascular treatment of aortic dissection.MethodsA total of 89 patients with aortic dissection involving left subclavian artery were treated by endovascular treatment in the Second Affiliated Hospital of Fujian Medical University from February 2017 to January 2020. There were 44 patients in the test group, including 36 males and 8 females, with an average age of 58.02±13.58 years. There were 45 patients in the control group, including 35 males and 10 females, with an average age of 54.10±12.32 years. The left subclavian artery was reconstructed by in vitro fenestration in the test group and by chimney technique in the control group. The clinical data were compared between the two groups.ResultsThe operation time of the test group was longer than that of the control group (126.16±7.53 min vs. 96.49±6.52 min, P<0.01). The median follow-up time was 31 (13-48) months. The incidence of endoleak in the test group (4.7%) was lower than that in the control group (18.6%, P=0.04) during the follow-up. There was no statistical difference in the incidence of stroke, myocardial infarction, false lumen thrombosis, retrograde aortic dissection or left subclavian artery occlusion between the two groups (P>0.05).Conclusion In vitro fenestration for reconstructing left subclavian artery in thoracic endovascular aortic repair of aortic dissection is safe and feasible, which is worthy of further clinical promotion.
ObjectiveTo investigate the efficacy of subclavian-carotid transposition (SCT) in treating patients with proximal subclavian artery occlusive diseases who were unable to be intervened, such as failure of intervention, congenital malformation and unwillingness to intervention.MethodsA retrospective review of 19 patients with proximal subclavian artery occlusion who underwent SCT from May 2016 to December 2018 was done. There were 14 males and 5 females with an average age of 54.05±17.34 years. The advantages and disadvantages of SCT in the treatment of proximal subclavian artery occlusion were analyzed.ResultsAll patients achieved immediate remission of symptoms after surgery. The stenosis degree of the proximal subclavian artery decreased from 100.0%±0.0% to 12.7%±10.1% after surgery. The average blood pressure difference between the unaffected side and the affected side decreased from 11.95±10.60 mm Hg to 0.89±5.75 mm Hg (P<0.01). Peripheral nerve injury occurred in 7 (36.8%) patients. The in-patient cost of subclavian artery occlusion patients who received subclavian artery interventional therapy in our hospital during the corresponding period was 3 392.12 yuan higher than that of the SCT group in average (if eliminating the patients whose cost was far from the average value, the cost of interventional therapy was 4 812.01 yuan higher than that of the SCT group in average). During 1-3 years' follow-up, 6 patients with neurological complication relieved. One- and three-year patency rates were 100.0%. No perioperative stroke, death or re-operation happened.ConclusionSCT is an ideal process for the patients with subclavian artery occlusion who cannot accept subclavian artery interventional therapy.
