Objective To explore the treatment experience of acute type-A aortic dissection with lower limb malperfusion.Methods From December 2012 to December 2016,479 cases of acute type A aortic dissection were treated surgically,including 39 patients with lower limb ischemia,including 27 males and 12 females,with mean age of(5 1.4 ± 12.4) years.All patients were treated with deep hypothermic circulatory arrest and were treated with single pump,double-tube and double-injected limbs.According to the patient's lower limb ischemia time,symptoms and signs,limb ischemia was assessed.If necessary,femoral artery-femoral arterial bypass was performed.For patients undergoing femoral arterial-femoral prosthetic bypass during the same period,postoperative follow-up monitoring,if necessary,secondary femoral-femoral arterial vascular bypass or osteofascial decompression.Results Early mortality rate was 17.9％ (7/39).32 cases of postoperative survival.The follow-up rate was 93.8％ (30/32),3 months to 3 years after the operation,the results were satisfactory.The over lower limb malperfusion recovery rate of follow-up patients was 96.7％ (29/30).Conclusion Positive operation for acute type-A aortic dissection with lower limb malperfusion is safe,feasible and effective.Concomitant or secondary bypass procedures are also possible to restore distal perfusion when necessary.Comprehensive evaluation of patient' s status is strongly recommended for optimal surgical decision making.

Objective To discuss the application of deep hypothermic circulatory arrest in surgical treatment of complex thoracoabdominal aortic aneurysms and its near-midterm effect.Methods The clinical data of 34 cases of thoracoabdominal aortic aneurysm in the center from August 2009 to June 2018 were analyzed retrospectively.All the patients underwent surgery under deep hypothermic circulatory arrest.There were 23 males and 11 females; aged 23 -67 years, mean(42.26 ±10.96) years old; Crawford type Ⅰ in 12 cases and Crawford type Ⅱ in 22 cases; aneurysms with a maximum diameter of 50 -120 mm, mean(65.26 ±16.09) mm;Marfan syndrome 15 cases, atherosclerosis 14 cases, aortic coarctation in 5 cases;22 cases of hypertension;28 cases of first aortic surgery, 6 cases of re-aortic surgery.Surgical transthoracic and abdominal incision, ext-racapsular approach, femoral artery and inferior vena cava intubation, deep hypothermic circulatory arrest technique to complete proximal anastomosis, arterial tube reconstruction of intercostal artery, abdominal organ blood supply artery and four The bifur-cated vessels were anastomosed, and the bifurcated vessels were anastomosed with the "Y"type artificial blood vessel trunk. The bilateral radial arteries were end-to-end anastomosis in the 10 mm artificial blood vessels of the "Y"type artificial blood vessels.Results There were no complications of cranial nerve system in the whole group , deep hypothermic circulatory arrest (17.68 ±4.88) min, ventilator assist time(34.88 ±16.04) hours, postoperative renal failure in 5 cases, after CRRT treat-ment After recovery, 1 case of paraplegia after operation, muscle strength recovered after cerebrospinal fluid drainage and de-compression, and 1 case died in the whole group, and died of multiple organ failure.The patients were followed up for 3 months to 5 years, and the results were satisfactory.The survivors did not die.The survivors did not die.However, 5 patients underwent thoracic aortic replacement under deep hypothermic circulatory arrest for the first time , and 4 patients underwent reo-peration because of distal vasodilation.The reconstructed intercostal artery occlusion occurred in 4 patients, but no paraplegia occurred.Conclusion When cross clamping the aorta is not feasible,it is safe to perform proximal anastomosis with deep hy-pothermic circulatory arrest.

Objective To evaluate the results of a hybrid procedure for treating Stanford type B1C aortic dissection. Methods In our center, 49 patients with Stanford type B1C aortic dissection underwent supra-arch branch vessel bypass and thoracic endovascular aortic repair (TEVAR) from December 2013 to December 2017. There were 33 males and 16 females with an average age of 60.4±5.5 years. Left common carotid artery to left subclavian artery bypass (n=29), right common carotid artery to left common carotid artery and left subclavian artery bypass (n=18), left common carotid artery to left subclavian artery and right common carotid artery to right subclavian artery bypass (n=2) were performed. Results Early mortality rate was 2.0% (1/49). Forty-eight patients survived postoperatively. The follow-up rate was 100.0% (48/48). The patients were followed up for 6 to 47 (26.8±11.9) months postoperatively. Chest pain relapsed in one patient 8 months after the operation. The whole aorta CTA showed type A1S aortic dissection in one patient 6 months after the operation, and the re-operation was satisfactory. There was no endoleak or paraplegia. Conclusion Initial results suggest that the one-stage hybrid procedure is a suitable therapeutic option for type B1C aortic dissection.

Objective : To assess the safety and feasibility of incision in the retroauricular sulcus for removal of benign tumors in the lower pole of the parotid gland and to provide some ideas for aesthetic consideration of parotidectomy. Methods: In total, 18 cases with benign tumors of the lower pole regions of the parotid gland were included in this study, including 9 pleomorphic adenomas, 2 myoepitheliomas, 5 Warthin tumors, 1 basal cell adenoma and 1 oncocytoma. Three months after the operation, facial paralysis and salivary fistula were assessed. A visual analog scale was used to score the cosmetic satisfaction of the surgical incision. Tumor recurrence was followed up 6 ~ 12 months after operation. Results: In 18 patients with benign tumors the lower pole regions of the parotid gland, the tumor diameter ranges from 1.0 to 3.1 cm, with an average value of 2.5 cm. All patients experienced successful complete removal of the parotid mass with the minimally invasive retroauricular approach, and all wounds healed in one stage after operation. No serious complications, such as permanent facial paralysis and tumor recurrence, occurred 3 months after the operation. The patients were satisfied with the appearance of the surgical incision (aesthetic score 9.3 ± 0.4), achieving the expected aesthetic effect. Conclusion This approach is feasible and safe for most small benign parotid tumors located in the lower pole region of the parotid gland and in the posterior region of the jaw. The scar is located in the retroauricular sulcus, which significantly meets the aesthetic needs of the concealed incision for patients.

Objective    To summarize the clinical experience in the treatment of high-risk patients with severe aortic valve disease by transcatheter aortic valve implantation (TAVI) via heart apex approach and to evaluate the early efficacy. Method    Five patients who underwent TAVI via heart apex approach from September 2017 to February 2019 in Henan Thoracic Hospital were retrospectively analyzed, including 3 males and 2 females, aged 65-84 (74.6±4.5) years. Result    All operations were performed through a small left incision into the thoracic cavity (3-5 cm), and then through the J-Valve transport system, the aortic valve was successfully released via heart apex after precise positioning under digital subtraction angiography. One patient developed ventricular fibrillation during the operation, and the operation was completed with the assistance of emergency femoral arteriovenous catheterization cardiopulmonary bypass; one patient underwent percutaneous coronary intervention first because of severe coronary stenosis; one patient had paroxysmal atrial fibrillation during the perioperative period, and had hepatorenal insufficiency and thrombocytopenia after the operation, and was improved after medical treatment; one patient had perivalvular leak during the operation, and was improved after re-implantation of the valve; one patient was in stable condition during operation and recovered smoothly after operation. Surgery was successful in all 5 patients. The follow-up time was 2-19 months, and the early clinical effect was good. Conclusion    The short-term clinical efficacy of TAVI via heart apex approach in the treatment of high-risk severe aortic valve disease is definite and safe, but the long-term and medium-term effects need to be further evaluated.
