OBJECTIVE: To discuss the value of anterior operation in fracture-dislocation of connect of cervical vertebrae and thoracic vertebrae. METHODS: From 1997, 21 patients with fracture-dislocation of connect of cervical vertebra and thoracic vertebrae were operated on. The interval between injury and operation was within 24 hours in 4 cases, 2-7 days in 9 cases, 8-14 days in 3 cases and within 4 weeks in 5 cases. The locations were C6,7 in 7 cases, C7 in 9 cases and T1 in 5 cases. The nerves function of spinal of all the cases have different degrees of injury. Classification of Frankel were the following: 3 cases of grade A, 6 cases of grade B, 9 cases of grade C, and 3 cases of grade D. The operative procedure included the following: anterior operation of cervical vertebrae; incision of most fracture vertebral body to decompress; transplantation of ilium bone grafting fusion; and internal fixation of anterior cervical vertebrae with locking-steel. RESULTS: In 21 patients, 1 died of accompanying by pulmonary infection; 20 were followed up 8 months to 3 years with an average of 21 months. All transplanted ilium had fused. The nerve function of spinal cord had recovered in different degrees(2 cases of grade A, 1 case of grade C, 9 cases of grade D and 8 cases of grade E); the turn of vertebral column was normal. No internal fixation failed. CONCLUSION: Anterior operation is a better way to treat fracture-dislocation of connect of cervical vertebrae and thoracic vertebrae with easy operation, less complications, satisfactory reduction of fracture and good stability.
Abstract： Objective To summarize our operative experiences of cardiac reoperation after mechanical valve prosthesis replacement and investigate the causes of reoperation and the perioperative techniques and operation methods. Methods From January 2001 to December 2008, we performed reoperation on 105 patients (59 males and 46 females, aged 50.2±10.6 years old) who had undergone mechanical valve prosthesis replacement. Among the patients, there were 31 cases of mitral valvular replacement (+ tricuspid valvular plasticity), 38 cases of aortic valvular replacement (+ tricuspid valvular plasticity), 11 cases of Bentall procedure, 7 cases of mitral and aortic bivalvular replacement (+tricuspid valvular plasticity), 8 cases of tricuspid valvular replacement, 6 cases of repairing of prosthetic leakage, and 4 others cases. The time interval between two operations was 3 months to 18 years (46.3 ±31.9 months). Before reoperation, the cardiac function (NYHA) of the patients was class Ⅱ in 27 patients, class Ⅲ in 53 patients, and class Ⅳ in 25 patients. Results There were 6 hospital deaths with a mortality of 5.71%(6/105). All others recovered to NYHA class ⅠⅡ. The causes of mortality included 1 case of multiple organ failure, 1 case of low cardiac output after operation, 1 case of aortic pseudoaneurysm rupture, 1 case of severe infection due to brain complication and 2 cases of prosthetic valve endocarditis (PVE). The causes for cardiac reoperation after mechanical valve prosthesis replacement were 67 cases of prosthetic leakage (63.80%), 16 cases of PVE (15.23%), 14 cases of prosthetic thrombosis (13.33%) and 8 cases of other valvular anomalies. Followup was done for 11 to 107 months, which showed two cases late deaths of cardiac arrest and cerebral hemorrhage. Conclusion Patients who have received mechanical valve prosthesis replacement may undergo cardiac reoperation due to paravalvular prosthetic leakage, paravalvular endocarditis, and prosthetic thrombosis. The keys to a successful cardiac reoperation include appropriate preoperative preparations, operational timing, and suitable choosing of cardiopulmonary bypass and operational skills.
In order to modify the plastic operation for lumbar spinostenosis, [symbol: see text]-shaped splitting of spinous process was designed. Fifty-six patients with lumbar spinostenosis were treated. There were 36 males and 16 females, age ranged from 32-67 years old (with an average of 48.9 years old). Among them, 8 patients operation on L2-L5 segments, 16 on L3-L5 segments and 22 patients on L4-L5 segments. After operation, 32 cases were followed up from 8 to 27 months. The results were: 1. The result of operation was excellent in 21 cases, good in 8 fair in 2 and poor in 1. The effective rate was 90.6%. 2. The rate of bony union from laminectomy was 95.1%. 3. The sagittal diameter and transverse diameter of the spinal canal were enlarged in an average of 6.4 mm and 3.2 mm, respectively, with a mean enlargement of 37.6%. The conclusion were that the plastic operation with [symbol: see text]-shaped splitting of spinous process for lumbar spinal canal was easy to handle and it could effectively prevent the lumbar instability and secondary stenosis following operation.
Objective To explore the intraoperative imaging to monitor the prosthetic fixation for the total hip arthroplasty (THA) and to increasethe accuracy of the primary THA prosthetic fixation. Methods From April 2000 to August 2005, 69 patients (75 hips) underwent THA monitored by the imaging (the imaged THA group, Group I), and 72 patients (78 hips) underwent THA with the standard method (the standard THA group, Group S). There were 32 males and 37 females in Group S. The mean ages of the patients in Group I and Group S were 62.3 years and 60.5 years respectively, ranging 46-75 years in Group I and 43-75 years in Group S. Preoperative diagnoses were femoral neck fracture (Garden Ⅲ,Ⅳ) in 23 patients (23 hips) in Group I and 25 patients (25 hips) in Group S, acetabular dysplasia (Campbell Ⅰ, Ⅱ) in 9 patients (10 hips) in Group I and 11 patients (13 hips) in Grouop S, osteoarthritis in 16 patients (17 hips)in Group I and 15 patients (15 hips) in Group S, femoral head osteonecrosis (Ficat Ⅲ,Ⅳ) 15 patients (16 hips) in Group I and 17 patients (17 hips) in Group S, and rheumatoid arthritis in 6 patients (9 hips) in Group I and 4 patients (8 hips) in Group S. There were 21 hips of cement prostheses in Group I and 22 hips in Group S, 12 hips of cementless prostheses in Group I and 11 hips in Group S, 42 hips of cement and cementless prostheses in Group I and 45 hips in Group S. Group I used the standard THA and the intraoperative X-ray monitoring the prosthetic fixation in the numerical measure of abduction angle, anteversion angle, femoralneck length, and femoral offset distance. The items compared betweem Group I and Group S included incisional length, intraoperative bleeding, transfusion, operative time, frequency of X-ray imaging, infection, postoperative functional recovery, and prostheric position of postoperative X-ray imaging. Results The follow-up on 62 patients in Group I and 64 patients in Group S for 6-64 months averaged 42 months revealed that there were statistically significant differences in incisional length, intraoperative bleeding, transfusion, operative time, frequency of X-ray imaging, postoperative functional recovery, prosthetic position of postoperative X-ray imaging, and the Harris score between Group I and Group S one year after operation. The results of Group I were significatly better than those of Group S. Conclusion The intraoperative X-ray imaging can increase the accuracy of the THA prosthetic fixation and reduce the incidence of THA maloperation by The X-ray imaging can also be used in county hospitals if Carm fluoroscopy can be provided.
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.
ObjectiveTo evaluate the safety and efficacy of peripheral cannulation for cardiopulmonary bypass (CPB) in patients with reoperation of congenital heart disease. MethodsThe perioperative data of patients with congenital heart disease who underwent reoperation in Fuwai Hospital from 2019 to 2020 were retrospectively collected. They were divided into two groups according to the cannulation methods: a central group and a peripheral group. The prognosis of the patients was analyzed. Results A total of 80 patients were collected, including 43 patients in the central group, and 37 pateints in the peripheral group. In the central group, the median age was 18 (14, 32) years, and 21 patients were male. The median age of the peripheral group was 16 (10, 27 ) years, and 18 patients were male. The CPB time in the peripheral group was 201 (164, 230) min, which was longer than that in the central group [143 (97, 188 ) min, P＜0.001]. The lactate after CPB in the peripheral group was statistically higher than that in the central group [2 (1, 2 ) mmol/L vs. 1 (1, 1) mmol/L, P=0.002]. The dosage of albumin use during CPB in the peripheral group was statistically higher than that in the central group [10 (0, 20) g vs. 0 (0, 0) g, P=0.004]. There was no statistical difference in the postoperative dosage of red blood cells use [0 (0, 2) U vs. 0 (0, 0) U, P=0.117], mechanical ventilation time [14 (11, 19) h vs. 13 (10, 15) h, P=0.296], ICU stay time [43 (23, 80) h vs. 40 (20, 67) h, P=0.237] or postoperative hospital stay time [10 (7, 12) d vs. 8 (7, 10) d, P=778] between the two groups. ConclusionIt’s safe and efficient to establish CPB through peripheral cannulation in patients with complex congenital heart disease undergoing reoperation.
ObjectiveTo investigate the effectiveness of rotation-embedding technology for treatment of moderate to severe inverted nipples.
MethodsBetween March 2012 and March 2014, 24 patients (39 nipples) with moderate to severe inverted nipples were treated using rotation-embedding technology. The age ranged from 28 to 42 years (mean, 32 years). The bilateral nipples involved in 15 cases, unilateral nipple in 9 cases, including 30 moderate inverted nipples, 9 severe inverted nipples. The first time operation was performed in the other patients except 1 patient who had received corrective operation of bilateral nipples.
ResultsThe operation was successfully performed in all patients; primary healing of incision was obtained; no swollen, bleeding, dehiscence, or blood flow obstacle occurred. All patients were followed up 5-24 months (mean, 12 months). The shapes of nipples were satisfactory; bilateral nipples were symmetrical basically; no nipple inversion recurred, and the nipple skins had good sensation.
ConclusionUsing rotation-embedding technology can correct moderate to severe inverted nipples effectively.
The surgical treatment of pectus excavatum has a history of more than 100 years, which has gone through from traditional open surgery to the current popular minimally invasive surgery. Nuss procedure, as the most classic minimally invasive operation, has been improved in accordance with the clinical needs since its inception to achieve fewer complications and better results, but there are still limitations that are difficult to break through, attracting a large number of scholars to make continuous innovation and develop updated devices and operation methods. This article reviews the history of funnel chest surgery, application and improvement of Nuss operation, double compression and complete fixation bar system and Wang procedure.
Objective To investigate the clinical effect ofthe pectoralis major myocutaneous flap and Ti-plate system in repairing mandibular defects caused by resection of oral carcinoma.Methods From November 2001 to February 2003, 32patients with mandibular defect caused by resection of oral carcinoma were treated. Combined radical neck dissection with resection of gingival and mandible was performed on 11 patients with carcinoma of the lower gingival, combined radical neck dissection with glossectomy and mandibulectory on 13 patients with carcinoma of tongue, combined radical neck dissection with resection of floor of mouthand mandible on 4 patients with carcinoma of floor of mouth, and combined radical neck dissection with resection of cheek and mandible on 4 patients with carcinoma of buccal mucosa, respectively. The defects of mandible were associated with soft-tissue component, the sizes of defect ranged from 5.5 cm×7.6 cm to 8.2 cm×10.5 cm. The defects were reconstructed with 6 cm×7 cm to 9 cm×10 cm pectoralis major myocutaneous flaps and Tiplate system. The effect was studied retrospectively. Results Thirty-two cases were followed for 219 months; 29 cases offlaps survived and 3 cases of flaps partly necrosed (10% or less of the skin paddle). The appearance of face was satisfactory in 27 patients, and slight deformity of face was observed in 5 patients. The occluding relation and masticatory function were recovered well. Opening mouth extents ranged from 2.7 cm to 3.4 cm. No temporomandibular arthrosis relating to operation was found in all cases. Conclusion A combination of thhe pectoralis major myocut aneous flap and Ti-plate system is an ideal method for reconstruction of mandible defects associated with soft-tissue component after radical operation of oral carcinoma.
In order to repair the intraoral defects after extensive resection of oral carcinoma with radical neck lymph nodes dissection, the nasolabial myocutaneous flap was prepared with its pedicle which only contained the facial artery and anterior facial vein. After removal of the tumor, the flap was used to cover the intraoral defect. Altogether 15 cases of oral squamous cell carcinoma were treated by this method. Seven out of 15 cases had their cervical lymph nodes involved. The tumor in all cases were located in one anatomical region, without involvement of accessory nerve or metastasis. All the flaps survived after the operation. There was no recurrence of tumor in any case after being followed up from 0.5-2 years. Removal of tumor and repaire of the defect by pedided naso-labial myocutaneous flap could be done in one stage. The detail of the process was introduced. Its feasibility and application were discussed. It was suggested that preserving the facial vessels be a kind of modified method of radical neck lymph nodes dissection, and the nasolabial myocutaneous flap have some clinical value in repair of the defect after radical operation of oral carcinoma.
