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 clinical value of cervical vascular color Doppler ultrasound for dignosis of nonrecurrent laryngeal nerve before thyroid surgery. MethodsThere were 1931 cases of thyroid patients treated between January 2010 to Jule 2014, group these patients according to the results of preoperative chest radiograph examination, the chest radiograph shows abnormal vessels image were group A (45 cases), no abnormalities were group B (1886 cases). Before operaton, made patients of group A to have routine carotid duplex ultrasound to identify whether the right subclavian artery abnormalities. All patients were exposed to conventional methods of recurrent laryngeal nerve during surgery. ResultsThe 45 patients of group A, chest angiography showed 17 cases with right subclavian artery abnormalities, they were confirmed that all the 17 patients were nonrecurrent laryngeal nerve by surgery, no damage cases. The other 28 cases showed a normal right subclavian artery and no cases of nonrecurrent laryngeal nerve. The 1886 patients in group B, surgical exploration found four cases with nonrecurrent laryngeal nerve, injury in 1 case. The 21 patients whose nonrecurrent laryngeal nerve were on the right side, there were no left side with nonrecurrent laryngeal nerve and no co-exist cases of nonrecurrent and recurrent laryngeal nerve. The average exposure time of nonrecurrent laryngeal nerve in patients of group A (17 cases) was significantly shorter than that group B[(4.28±1.08) min vs. (15.50±2.08) min, t=-15.978, P=0.000]. ConclusionsThe cervical vascular color Doppler ultrasound examination before thyroid surgery can be adjuvant used, if there is the right subclavian artery abnormalities, it showes that there is the right side nonrecurrent laryngeal nerve. So as to effectively prevent the damage of nonrecurrent laryngeal nerve during thyroid surgery.
Objective To summarize our experience and the early and midterm outcomes of stented elephant trunk procedure for right-sided aortic arch (RAA) with Kommerell's diverticulum (KD). Methods From April 2013 to July 2020, patients with RAA and KD who underwent stented elephant trunk procedure at our center were collected. Surgery was performed under moderate hypothermic circulatory arrest combined with selective antegrade cerebral perfusion via median sternotomy. Results A total of 8 patients were included, including 7 males and 1 female with a mean age of 51.88±9.61 years. All patients had an aneurysmal KD and aberrant left subclavian artery. Preoperative comorbidities included acute Stanford type B aortic dissection in 1 patient, aortic arch pseudoaneurysm in 1 patient, acute type B intramural hematoma in 2 patients, and coronary artery disease in 1 patient. Concomitant procedures included reconstruction of the left subclavian artery in all patients and coronary artery bypass grafting in 1 patient. The mean time of operation, cardiopulmonary bypass, aortic cross-clamping, and selective cerebral perfusion was 6.25±1.16 h, 157.75±40.07 min, 77.75±33.10 min, and 28.50±5.55 min, respectively. No intraoperative death occurred. There was 1 in-hospital death. Follow-up was completed in all patients with a mean period of 3.58±2.08 years. No late death occurred. A persistent anastomotic leak of the proximal arch was detected in 1 patient, but reintervention was not performed because neither aortic dilatation nor symptoms of tracheal and esophageal compression were observed during the follow-up. The remaining 6 patients showed positive aortic remodeling with complete thrombosis of the aneurysmal KD, and neither aortic event nor tracheal and esophageal compression occurred. Conclusion Stented elephant trunk procedure is a safe and feasible technique for selected patients with RAA and KD, which can achieve favorable early and midterm outcomes.
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.

ObjectiveTo report a simple and safe method for in situ fenestration of left subclavian artery in thoracic endovascular aortic repair (TEVAR).MethodsTwenty-eight patients received in situ fenestration of left subclavian artery in TEVAR from June 2018 to May 2019 in our center, including 23 males and 5 females at an average age of 57.7±9.6 years. Among them, 12 patients used adjustable sheath or guiding catheter (a group A) and 16 patients used "J. D"technique (a group B). The clinical efficacy of the two groups was compared.ResultsIn the group A, 1 patient failed to receive fenestration and was transferred to the chimney technique. In the group B, 1 patient due to the traction system shift during operation, was completed by traditional adjustable sheath puncture. The group B had shorter alignment-perforation time and trigger time and less complications. There was no significant difference in endoleak during short-term follow-up between the two groups.ConclusionThe "J. D" technique is simple, safe and easy to obtain materials. It effectively reduces the risk caused by difficult sheath alignment during the in situ fenestration of the left subclavian artery. Although the results of recent follow-up are not significantly different from traditional methods, it still needs to accumulate the cases to observe the possible risks and difficulties.
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.
Objective To explore the treatment of traumaticsubclavian artery. Methods From July 1990 to January 2006, 12 cases of traumatic subclavian artery were treated byusing of combined incision of superior-inferior clavian. All patients were male,aging 18-36 years(mean 22.6 years). The locations were section 1 of subclavianartery in 1 case, section 2 in 4 cases and section 3 in 7 cases. All patients had incomplete rupture and defect. Time from injury to operation was 3 hours to 1.5 months. The methods of vascular repair included primary repair, end-to-end anastomosis and artificial vascular prosthesis grafts. Results There was no death. Extremities survived in all cases and got good function in 10cases.All patients were followed up 2 months to 12 years (mean 5 yeras and 2 months). The pulse of radial artery restored to normal in 10 cases and did not be felt in 2 cases. The function of extremities restored to normal in 2 cases withpartial injury of brachial plexus nerve and did not improve in 2 cases with complete injury ofbrachial plexus nerve. 〖WTHZ〗Conclusion The exposure of subclavian artery is difficult because of its particular anatomy region. The repair and reconstruction of subclavian artery should be selected according to the type of vascular injuries. Combined superiorinferior clavian approach can satisfy the exposure and repair for the 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.
