Abstract: Objective To investigate the method of improving effect, by investigating and analyzing the possible risk factors affecting shortterm outcome after total correction of tetralogy of Fallot (TOF). Methods Data of 219 patients who received total correction of TOF were divided into two groups according to the length of postoperative stay in hospital and recovery of heart function in the near future. Group A(n=110): patients had good recovery of heart function classified as gradeⅠorⅡ（NYHA classification）, and could smoothly be discharged from the hospital within two weeks without serious complications. The left ventricular ejection fraction (LVEF) had to exceed to 0.50 during 6 months followup visit. Group B(n=109): patients had worse recovery of heart function classified as grade Ⅱ or Ⅲ, and could not be discharged within two weeks with severe complications. LVEF was less than 0.50 during 6 months followup visit. The clinical data of two groups were compared, and risk factors affecting shortterm outcome after total correction of TOF operation were analyzed by logistic regression and model selection. Results There were good recovery of heart function classified as gradeⅠorⅡ(NYHA classification）in discharge, no death, and LVEF all exceeded to 0.50 in group A; there were 8 deaths in group B (7.34 %), and recovery of heart function was worse classified as grade Ⅱ or Ⅲ, with LVEF being less than 0.50（Plt;0.01）. Amount of postoperative daily thoracic drainage, assisted respiration time, time of inotropic agent stabilizing circulation, and the average length of postoperative stay in group A were all less or short than those in group B（Plt;0.01）. But the bypass and clamping time of group B were exceeded group A. The ratio of patching astride annulus in group B was greater than that in group A, and Nakata index was less than that in group A(Plt;0.01). The results of logistic regression and model selection indicate: age at repair (OR=0.69), oxygen saturation(OR=0.98), haematocrit before operation (OR=0.94), and patching astride annulus (OR=46.86), Nakata index (OR=16.90), amount of postoperative daily thoracic drainage (OR=0.84), presence of arrhythmia(OR=0.87), and wound infection(OR=63.57) have significant effect with shortterm outcome after total correction of TOF operation. Conclusions The probable methods to improving effect of shortterm outcome after total correction of TOF are an earlier age at repair, decreasing haematocrit, rising oxygen saturation before surgery, performing a palliative operation facilitating development of arteriae pulmonalis in earlier time, improving the surgical technique, and strengthening the perioperative care.
Objective To comprehend the concept， pathology， molecular mechanisms， diagnosis， and treatmentof aggressive fibromatosis （AF）， and to find a novel way to cure aggressive fibromatosis. Method The literatures about the definition， molecular mechanisms， and clinical research of AF were reviewed and analized. Results AF is rare and benign fibromatous lesion that is the result of abnormal proliferation of myofibroblasts. The pathologic features of AF isa benign disease， but it has “malignant” biological behavior. The tumor often involved the surrounding organs and bloodvessels， and caused death of patients. For patients with clinical symptoms or complications， complete excision of thetumor is the treatment of choice. Even if the operation to ensure the negative margin also has a higher recurrence rate， soits treatment requires multidisciplinary treatment. Conclusions The mechanism of AF is very complex， and it’s mecha-nism is still unclear. Clinical management of patients with AF is difficult and controversial， at present， the most effective treatment for AF is operation resection. The effects of adjuvant radiotherapy， chemotherapy， and other treatment after operation for AF still need further study.
OBJECTIVE: To explore a better surgical mode to treat gluteal muscle contracture. METHODS: In 98 cases, superior cross incision of large tuberosity was performed in 20 cases, posterosuperior curve incision of large tuberosity was performed in 20 cases, and exteroinferior cross incision of iliac spine in the other 58 cases. The patients were observed after operation and followed up. RESULTS: The patients who received exteroinferior cross incision of iliac spine recovered soon without bleeding and infection after operation, which indicated the lowest incidental rate of postoperative complication. CONCLUSION: Exteroinferior cross incision of iliac spine is a safe and effective surgical operation to loosen the gluteal muscle contracture.
Objective To study the clinical features of duodenal trauma and its surgery to improve the level of diagnosis and treatment. Methods Methods of diagnosis and results of surgical treatment were analysed retrospectively of 35 cases of duodenal trauma. Results The positive rates of abdominal X-ray and abdominal puncture were 32.0%, 13.3% respectively. The extraperitoneal duodenal injuries occured in 30(85.7%) cases. 25(71.4%) cases were complicated by additional intraabdominal organ injuries. The rate of failure to diagnose intraoperatively was 11.4%. The postoperative complication rate was 37.1% and the death rate was 11.4%. Conclusion Duodenal trauma is characteristic of low diagnostic rate preoperatively, high failure rate intraoperatively and most of the cases are complicated by other intraabdominal organ injuries, so both the complication and mortality are high. If the diagnosis is certain, surgery should been taken suitably. This is the key to improve prognosis. The procedure performed is based on the condition of duodenal injuries.
For the evaluation of the result from McKay operation in the correction of rigid clubfoot, 71 patients (103 feet) were followed up postoperatively for 2 to 9 years. According to the criteria concerning the functional recovery of the foot, the external appearance of the foot after correction and the roentgenographic findings, the result was evaluated as excellent in 55 patients (78 feet), good in 11 patients (16 feet), fair in 5 patients (9 feet) and with no recurrence. It was considered that the favorable time for operation was when the child being 6 to 18 months old. In 7 patients (12 feet), there were morphological changes of the calcaneal and navicular bones in 12 feet, limitation of ankle movement in 9 patients and resultant flatfoot deformity in 5 patients (7 feet). The factors influencing the functional recovery of the foot and the relationship between the corrective result and the age of patient when the operation being given were discussed in details.
Objective To investigate the postoperative treatment of pleuropneumonectomy for tuberculosis destroyed lung in ICU, in order to improve the therapeutical efficacy for these patients. Methods Clinical data of 52 patients who suffered from tuberculosis destroyed lung and underwent pleuropneumonectomy from June 2008 to June 2010 were analyzed retrospectively. All of subjects received routine treatment in ICU after the operation. Meanwhile，appropriate targeting treatments were applied including diagnosis and treatment of postoperative bleeding; application of fiberbronchoscope to aspirate the sputum after the operation,sequential non-invasive ventilation after the invasive ventilation for acute respiratory failure after operation ,etc.Results A total of 52 patients received the pleuropneumonectomy operation. Bleeding occurred in 11 cases after operation and stopped after the integrated therapy. 8 patients suffered from acute respiratory failure and attenuated after sequential ventilation. No patients died for postoperative bleeding or acute respiratory failure. Conclusions Patients who suffered from tuberculosis destroyed lung and received pleuropneumonectomy with postoperative bleeding and acute respiratory failure have a good prognosis after appropriate postoperative treatment in ICU.
Objective To investigate the impact of three kinds of palliative operation on the body and growth of pulmonary artery in patients with congenital heart diseases of diminutive pulmonary blood. Methods Clinical data was reviewed in 28 cases of congenital heart diseases with diminutive pulmonary blood who had been performed cavopulmonary connection （n = 9）, systemic-pulmonary shunt （n = 8 ）, and palliative reconstruction of right ventricular outflow tract （n=11）. The period between re-hospitalized and the first was 5-54 months （19.07±10. 06 months ）. Hematocrit （HCT）, hemoglobin （Hb）, percutaneous oxygen saturation （SpO2）, body surface area （BSA）, and pulmonary artery index （PAI） etc. were observed both before palliation and before the second operation. Results After the second hospitalization, there were 7 cases of death from hemorrhage, failure of circulation and extracorporeal circulation accident etc. The time of respirator, intensive care unit and total amount of dopamine in patients of palliative reconstruction of right ventricular outflow tract were longer and more than those in patients of cavopulmonary connection （P〈0. 05）. HCT, Hb before the second operation were decreased than thoes before palliative operations in all patients, SpO2, BSA and PAI increased significantly （P 〈 0. 01 ）. Before the second operation, BSA of patients with cavopulmonary connection, BSA and PAI of patients with systemic-pulmonary shunt, SpO2, BSA and PAI of patients with palliative reconstruction of right ventricular outflow tract were increased than those before palliative operations（P〈0. 01）. HCT of palliative reconstruction of right ventricular outflow tract was decreased（P〈0. 05）. Conclusion This results suggests that pulmonary blood of patients with congenital heart diseases of diminutive pulmonary blood can be increased, development of pulmonary arteries can be improved efficiently by systemic-pulmonary shunt and palliative reconstruction of right ventricle outflow tract, but it can not be found in cavopulmonary connection patients.
Objective To investigate the methods and effectiveness of multi ple surgical treatment for complex aortic arch and descending aorta disease, including cardiopulmonary bypass operation, hybrid operation, and total endovascular aneurysm repair (EVAR). Methods Between October 2006 and September 2011, 48 patients with complex aortic arch anddescending aorta disease were treated. There were 31 males and 17 females, aged from 28 to 81 years (mean, 52.4 years). The disease duration ranged from 1 to 90 days (mean, 10.2 days). There were 30 cases of type B aortic dissection involving the aortic arch, 11 cases of thoracic aortic aneurysm, 3 cases of thoracic pseudoaneurysme, 3 cases of penetrating aortic ulcer, and 1 case of aortoesophageal fistula. Cardiopulmonary bypass operation, hybrid operation, and total EVAR were performed in 15, 12, and 21 cases, respectively. Results In the patients undergoing cardiopulmonary bypass operation, the following complications occurred: 1 case of bleeding, 1 case of coma, 3 cases of psychiatric disorders, 4 cases of pneumonia, 2 cases of acute renal insufficiency, and 2 cases of multi-organ dysfunction; finally 3 patients died. In the patients undergoing hybrid operation, cerebral infarction and renal function failure occurred in 1 case. In the patients undergoing total EVAR, no complication occurred. A total of 41 patients were followed up 2 to 60 months (mean, 28.6 months). Sl ight left subclavian steal syndrome occurred in 3 cases, but self rel ieved. Other patients recovered to normal l ife. Conclusion In the surgical treatments of complex aortic arch and descending aorta disease, cardiopulmonary bypass operation will be gradually replaced by EVAR because of the surgical trauma and risk, hybrid operation is an important technique, and total EVAR will be the future progress.
Objective To explore the effective method for treatmentof fracturesof scapular neck.Methods A retrospective analysis of 30 patients with fractures of scapular neck was done. The patients were treated by operation or by nonoperation from May 1994 to May 2003. According to the degree of displacement,30 cases included 9 mild displaced fractures(lt;10 mm) and 21 severe displaced fractures(gt;10 mm). According to the location of fractures, there were 24 cases of surgical neck fractures and 6 cases of anatomical neck fractures. Of all 30 patients, 12 were treated by nonoperation and 18 by operation. All fractured scapularnecks were exposed through posterior approach and fixed with interfragmentary compression screws, reconstruction plates and so on after satisfactory reduction.Associated clavical fractures were exposed through Langer’s approach and fixed with Kirschner wire-tension band fixation construct, reconstruction plates and so forth. When followed up, the clinical examination was done and the X-ray filmswere taken to measure glenopolar angle(GPA). Herscovici’s score was adopted.Results Twenty-eight patients were followed up from 14 days to 9 years. Among 11 patients treated by non-operation, Herscivici score showed that 4 cases achieved the excellent result, 2 cases good, 2 cases fair and 3 cases poor and the X-ray film results showed that there were 6 cases of GPA＞20° and 5 cases of GPA＜20°. Of 17 patients treatedby operation, Herscivici score showed that 11 cases achieved the excellent result, 5 cases good and 1 case fair and the X-ray film results showed that there 16 cases of GPA＞20° and 1 case of GPA＜20°.Conclusion Fractures of scapular surgical neck with mild displacement can be treated by nonoperation, while fractures of surgical neck with severe displacement or associated with ipsilateral clavical fractures, and fractures of anatomical neck should be treated by operation to reconstruct the stabilityof shoulder and minimize the complications.
Objective To investigate the effect of perioperative body temperature on the survival of skin flap grafting. Methods From July 2005 to November 2006, 50 cases of Ⅰ-Ⅱ grade patients undergoing elective skin flap grafting were randomly divided 2 groups. Pharyngeal temperature (PT) and skin temperature(ST) were monitored and recorded every 15 minutes. Operativetime, anesthetic time, time from the end of operation to extubation, the volume of blood transfusion, the volume of fluid transfusion and the flap survival 7 days after operation were recorded. In the experimental group, the body temperature was maintained in normal range with water market and forced air heater. In the control group， the body temperature was only monitored without any treatment. Results There were no significant differences in operating room temperature, operative time, anesthetic time, the volume of blood transfusion and fluid transfusion between 2 groups(Pgt;0.05). After induction, PT decreased gradually inboth groups during the first 45 minutes, compared with the time point of intubation(Plt;0.05),but there were no significant differences between the 2 groups(Pgt;0.05); and ST rose in both groups during the first45 minutes, compared with the time point of intubation (Plt;0.05). After 45 minutes of induction, in the experimental group, PT was in the normal range(36℃), and ST didn’t change compared with that of the timepoint of induction(Pgt;0.05). In the control group, both PT and ST decreasedgradually and timedependently compared with the time point of intubation (Plt;0.05). In the experimental group, PT and ST at each time point were higher than those in the control group (Plt;0.05). All the skin flap grafts survived in the experimental group, and skin flap grafts necrosed in 2 cases in the control group.Conclusion Keeping normal body temperature can improve the survival ofskin flap grafting. Therefore, the body temperature should be monitored and maintained in a normal range.
