    • TRANSPOSITIONAL ANASTOMOSIS OF C7 POSTERIOR ROOT AND SPINAL ACCESSORY NERVE TO RECONSTRUCT THE TRAPEZIUS MUSCLE FUNCTION

      Objective To introduce a new approach of neurotization to treatment of the shoulder syndrome after the radical neck dissection by using transpositional anastomosis of C7 posterior root and the spinal accessory nerve to reconstruct the function of trapezius muscle. Methods From March 1999 to February 2001, 10 patients underwent the neurotization during the radical neck dissection. In the operation, the apo-cranial part of spinal accessory nerve was preserved from the trapezius muscle (gt;3.0 cm in length) and anastomosed to C7 posterior root. Objective physical examinations and electromyography were conducted before and after operation.One, 6 and 12 months after operation the trapezius muscle function after the transpositional anastomosis was evaluated. Results One, 6 and 12 months after operation, the recovery rates of each part were as follows: 9.8%, 68.9% and 73.5% in upper part; 4.7%, 73.6% and 69.4% in middle part; and 6.2%, 70.5% and 70.3% in lower part. The range of abduction motion of upper arm in 7 cases (70%) exceeded 90°. The mean maximal abduction angle was more than 95°. Evaluation of the shoulder function showed that myoatrophy was mild and the disability of abduction was classified as grade Ⅱ in 7 cases and grade Ⅲ in 3 cases. Conclusion Transpositional anastomosis of the C7 posterior root to thespinal accessory nerve after radical neck dissection can well reconstruct the function of trapezius muscle. This approach provides a wide indication in comparison with the functional neck dissection without impairment of arm function afterthe cutting of C7.

    • Long-Term Effects of Partial Axillary Dissection in Modified Radical Mastectomy of Breast Cancer

      Objective To study the effects of partial axillary lymph node dissection (PALD) on prognosis and upper limb function in patients with breast cancer. Methods Ninety-eight breast cancer patients with stage Ⅰ and Ⅱ were randomly divided into two groups and different surgical procedures following modified mastectomy were performed: partial axillary lymph node (level Ⅰ and Ⅱ) dissection (PALD) group (n=48) and total axillary lymph node (levelⅠ, Ⅱ and Ⅲ) dissection (TALD) group (n=50). The longterm positive relapse rate and upper limb function between 2 groups were compared. Results During the follow-up of 5 to 10 years (average 4.5 years), there were 2 cases (4.2%) of local recurrence on chest wall and one case (2.1%) of recurrence in axillary lymph node and one case (2.1%) of recurrence in supraclavicular lymph node in PALD group, and 2 cases (4.0%) of local recurrence on chest wall and no axillary lymph node recurrence and one case (2.0%) of recurrence in supraclavicular lymph node happened in TALD group. There was no statistical difference between PALD group and TALD group (Pgt;0.05). The incidence of upper limb edema and dysfunction was 4.2% (2/48) in PALD group and 16.0%(8/50) in TALD group (P<0.01). There was no significant statistical difference of 5year and 10year survival rate between PALD group and TALD group (89.6% vs. 88.0%, 79.2% vs. 78.0%,Pgt;0.05). Conclusion PALD may reduce upper limb dysfunction after operation in patients with stage Ⅰ and Ⅱ breast cancer, and does not increase prognostic risk.

    • Analysis of Risk Factors of Preoperative Sudden Death of Patients with Type A Aortic Dissection

      Objective To analysis correlation factors for preoperative sudden death of patients with type A aortic dissection in order to determine clinical management strategy.?Methods?We retrospectively analyzed clinical data of 52 patients with type A aortic dissection who were admitted in Department of Cardiothoracic Surgery of the Affiliated Drum Tower Hospital of Nanjing University Medical School from January 2003 to January 2010. According to the presence of preoperative death, all the patients were divided into two groups, 9 patients in the preoperative sudden death (PSD)group including 7 males and 2 females with their mean age of 52.0±12.1 years;43 patients in the control group including 31 males and 12 females with their mean age of 51.5±10.9 years. Univariate and multivariate logistic regression analysis were used for analysis of preoperative factors related to sudden death.?Results?Univariate analysis result showed 7 candidate variables:body mass index (BMI, Wald χ2=2.150, P=0.143), time of onset (Wald χ2=2.711, P= 0.100), total cholesterol (TC, Wald χ2=1.444, P=0.230), low density lipoprotein cholesterol (L-C, Wald χ2=1.341, P=0.247), aortic insufficiency (AI, Wald χ2=2.093, P=0.148), aortic sinus involvement (Wald χ2=3.386, P=0.066)and false lumen thrombosis (Wald χ2=7.743, P=0.005). Multivariate logistic regression analysis showed that BMI (Wald χ2=4.215, P=0.040, OR=1.558)and aortic sinus involvement (Wald χ2=4.592, P=0.032, OR=171.166 )were preoperative risk factors for sudden death, and thrombosed false lumen (Wald χ2=5.097, P=0.024, OR=0.011)was preoperative protective factor for sudden death.?Conclusion?Type A aortic dissection patients with large BMI and/or aortic sinus involvement should receive operation more urgently than others and patients with thrombosed false lumen may have relatively low risk of preoperative sudden death.

    • Optimized arterial perfusion strategy in total arch replacement for acute type A aortic dissection with malperfusion syndrome

      ObjectiveTo investigate the effect of optimized arterial perfusion strategy on total arch replacement for acute type A aortic dissection (AAAD) with malperfusion syndrome (MPS).MethodsFrom 2017 to 2019, 51 patients with AAAD and MPS who had received total arch replacement with optimized arterial perfusion strategy in our hospital were included in the optimized perfusion group, including 40 males and 11 females, with an average age of 47.43±13.39 years. A total of 40 patients with AAAD and MPS who had been treated with traditional Sun's surgery were taken as the traditional control group, including 31 males and 9 females, with an average age of 50.66±12.05 years. The perioperative clinical data of the two groups were compared.ResultsThe preoperative baseline data of the two groups were basically consistent (P>0.05). The comparison of operative data between the optimized perfusion group and the traditional control group showed that in the optimized perfusion group, the extracorporeal circulation time, aortic occlusion time, and circulation-out cerebral perfusion time were significantly less than those in the traditional control group (223.64±65.13 min vs. 266.77±87.04 min, 114.48±27.28 min vs. 138.20±39.89 min, 8.28±3.81 min vs. 50.53±23.60 min, all P≤0.05). The lowest intraoperative nasopharyngeal temperature in the optimized perfusion group was significantly higher than that in the traditional control group (27.10±1.18℃ vs. 23.6±3.30℃, P=0.000). Postoperative wakefulness time of the optimized perfusion group was earlier than that of the traditional control group (4.50±1.35 h vs. 5.27±1.15 h, P=0.019). The volume of blood transfusions in the optimized perfusion group was significantly less than that in the traditional control group (13.25±9.06 U vs. 16.95±7.53 U, P=0.046). There was no significant difference in ICU time and invasive ventilation time between the two groups (P>0.05). Postoperative complications of the two groups showed that the incidence of postoperative continuous renal replacement therapy in the optimized perfusion group was significantly lower than that in the traditional control group, with a statistically significant difference (21.6% vs. 42.5% P=0.003). The incidence of postoperative delirium, coma, low cardiac row syndrome and limb ischemia in the optimized perfusion group was lower than that in the traditional control group, but the difference was not statistically significant (P>0.05). The incidence of postoperative hemiplegia, sepsis, and secondary thoracotomy in the optimized perfusion group was higher than that in the traditional control group, and the difference was not statistically significant (P>0.05). Postoperative mortality in the optimized perfusion group was significantly lower than that in the traditional control group (13.7% vs. 27.5%), but the difference was not statistically significant (P=0.102).ConclusionOptimized arterial perfusion strategy and its related comprehensive surgical technique reduce surgical trauma, shorten the operation time, reduce perioperative consumption of blood products. Postoperative wakefulness is rapid and the incidence of complications of nervous system, kidney and limb ischemia is low. Optimized arterial perfusion strategy is suitable for operation of AAAD with MPS by inhibiting the related potential death risk factors to reduce operation mortality.

MethodsFrom January 2011 to September 2014, 17 patients diagnosed with aortic arch dissection by CT angiography undergoing the hybrid procedure (thoracic endovascular aortic repair combined with supra-arch branch vessel bypass) in the department of Thoracic Cardiovascular Surgery, Wuhan General Hospital of Guangzhou Command. There were 12 males and 5 females aged from 46 to 71 years. Their clinical data, including the imaging findings, treatment, and prognosis were retrospectively analyzed. ResultsLeft common carotid artery (LCCA) to left subclavian artery (LSA) bypass (n=4), right common carotid artery (RCCA) to LCCA to LSA bypass (n=3), RCCA to LCCA bypass merger covered LSA (n=3) were performed. All operations were successful. Laryngeal recurrent nerve injury occurred in one patient. All patients were followed up on the postoperative day 7, 30 and one year. All patients were followed up for 12 to 53 months till September 2015. There was no death, and no complications such as endoleak after the hybrid procedure, stenosis or blockage of the bypass graft during the follow-up period. ConclusionInitial results suggest that the hybrid procedure without sternotomy is a suitable therapeutic option for high risk aortic arch dissection patients in poor general condition with little tolerance to aortic arch replacement.

    • Different End-to-end Anastomotic Methods for Surgical Treatment of Acute Stanford Type A Aortic Dissection

      ObjectiveTo summarize clinical outcomes of different end-to-end anastomotic methods for surgical treatment of acute Stanford type A aortic dissection (AD). MethodsBetween January 2012 and May 2013, 95 patients with acute Stanford type A AD received surgical treatment in Nanjing Hospital Affiliated to Nanjing Medical University. According to different end-to-end anastomotic methods, 72 patients were divided into 3 groups (23 patients undergoing Bentall procedure were excluded from this study). In group A, there were 23 patients including 18 males and 5 females with their age of 48.67±9.23 years, who received 'sandwich' anastomotic technique strengthening both the inner and outer layers of the aortic wall. In group B, there were 11 patients including 8 males and 3 females with their age of 48.00±9.17 years, who received pericardium strengthening only inner layer of the aortic wall. In group C, there were 38 patients including 29 males and 9 females with their age of 49.20±8.57 years, who received artificial graft that was anastomosed directly to the aortic wall without any reinforcement. Postoperative outcomes were compared among the 3 groups. ResultsEight patients (11.11%)died postoperatively including 1 patient in group A (1/23, 4.35%)and 7 patients in group C (7/38, 18.42%). One patient in group A died of persistent wound errhysis and later disseminated intravascular coagulation. Three patients in group C died of persistent anastomotic incision errhysis and circulatory failure. Four patients in group C died of postopera-tive severe tricuspid regurgitation, secondary severe low cardiac output syndrome and multiple organ dysfunction syndrome. Severe postoperative complications included renal failure in 5 patients, respiratory failure in 7 patients, severe cerebral infarction and paralysis in 1 patient, paresis in 3 patients, delayed recovery of consciousness in 2 patients, and ischemic necrosis of the lower limb in 1 patient. Postoperative thoracic drainage amount in group C was significantly larger than that of the other 2 groups, and there was no statistical difference in thoracic drainage amount between group A and group B. Sixty-four patients were followed up for 1 to 6 months, and there was no late death during follow-up. Among the 5 patients with postoperative renal failure, only 1 patient needed regular hemodialysis, and renal function of the other 4 patients returned to normal. One patient with cerebral infarction recovered partial limb function and was able to walk with crutches. All the 3 patients with paresis recovered their limb function. ConclusionsAnastomotic quality of end-to-end anastomosis is of crucial importance for surgical treatment of acute Stanford type A AD. Appropriate reinforcement methods can be chosen according to individual intraoperative findings. 'sandwich' anastomotic technique can significantly reduce incision errhysis, prevent acute myocardial infarction caused by aortic anastomotic tear, and decrease postoperative mortality. If coronary ostia are involved in AD, concomitant coronary artery bypass grafting is needed.

    • Surgical treatment of pregnancy complicated with aortic dissection

      Objective To summarize the characteristics and management of pregnancy complicated with aortic dissection, and to explore the reasonable diagnosis and treatment plan. Methods The clinical data of 10 patients of pregnancy complicated with aortic dissection in Wuhan Tongji Hospital from January 2011 to June 2017 were collected. Their age was 25.2 (21-29) years. Results In the 10 patients, the majority (8 patients) were primipara, and most of them were in the late stages of pregnancy (5 patients) and puerperal (4 patients). Among them, 1 patient had gestational hypertension, and the blood pressure of the left and right upper extremities was significantly abnormal (initial blood pressure: left upper limb blood pressure: 90/60 mm Hg, right upper limb blood pressure: 150/90 mm Hg). The major clinical manifestations were severe chest and back pain which happened suddenly, with D-dimmer and C-creative protein increased which may be associated with inflammatory reaction. All patients were diagnosed by thoracoabdominal aortic CTA, including 5 patients of Stanford type A dissection and 5 patients of Stanford type B dissection. In the 10 patients, 1 patient refused surgery and eventually died of aortic rupture with the death of fetus before birth. And the remaining 9 patients underwent surgical treatment, 3 patients of endovascular graft exclusion for thoracic aortic stent graft, 2 patients underwent Bentall operation, 1 patient with Bentall + total aortic arch replacement + vascular thoracic aortic stent graft, 1 patient with Bentall operation combined with endovascular graft exclusion for thoracic aortic stent graft, 1 patient with Bentall + coronary artery bypass grafting, 1 patient of thoracoabdominal aortic vascular replacement. Among them, 1 patient underwent endovascular graft exclusion for thoracic aortic stent graft died of severe postoperative infection, and the remaining 8 patients were discharged from hospital. Nine patients were single birth, among them 5 newborn patients had severe asphyxia, 4 patients had mild asphyxia. Finally, 3 neonates died of severe complications, and the remaining 6 survived. Conclusion The ratio of pregnancy with Stanford type A aortic dissection is far higher than in the general population, the possibility of fetal intrauterine asphyxia is larger, but through active and effective surgical and perioperative treatment, we can effectively save the life of mother and fetus.
