To evaluate the long-term result of free forearm skin flap in the repair of soft tissue defects of the oral and maxillofacial regions, 26 cases which had received radical resection of maxillofacial tumors were follow-up for 4.5 years. Twenty cases, having complete data were analyzed. In this series, There were 8 males and 12 females, with ages ranged from 40 to 69 years old. The size of the flaps ranged from 4 cm x 5 cm-6 cm x 13 cm. The radial artery and the cephalic vein were used as the donor vessels, and the maxillary artery, superior thyroid artery, external jugular vein and the anterior jugular vein were prepared as the recipient vessels. According to the shape, colour, temperature, sensation, mucosoid degree of the flap, the blood supply and function of hand and the configuration of the forearm, the overall results of the recepient regions in 20 cases were all satisfactory and the overall results of 16 cases donor regions were satifactory in 16 cases. The results were poor in 4 cases. The conclusion were: 1. Free forearm skin flap was worth trying in the repair of soft tissue defects of oral region; 2. The radial artery need not to be reconstructed because of the abandant vascular net-work in the upper limb and 3. The residual scar on the forearm was the main shortcoming, but most of the patients could tolerate it because of the obvious advantages received from the operation.
ObjectiveTo summarize the indication and surgical experiences of valve replacement, high-risk factors and long-term results for aortic regurgitation and large left ventricle.
MethodsWe retrospectively analyzed the clinical data of 42 patients with aortic regurgitation and left ventricle end-diastolic diameter (LVEDD) ≥70 mm and left ventricle end-systolic diameter (LVESD) ≥ 50 mm in our hospital from March 2004 through December 2012. There were 38 males and 4 females,aged 16-73 (45.86±14.99) years. The patients underwent aortic valve replacement, who were evaluated by echocardiography at pre-operation, pre-discharge and early follow-up. The follow up period was 12-132 months.
ResultsEarly death occurred in one patient. And five patients died during the follow-up. One week after surgery in 41 patients, LVEDD (62.00±13.21 mm), LVESD (50.71±14.02 mm), indexed LVEDD (35.23±8.58 mm/m2), indexed LVESD (28.92±9.08 mm/m2), LVEF (46.41%±12.49%), were significantly smaller than those before the operation (P<0.01). Heart function grades, preoperative EF, LVEDD and indexed LVEDD were the predictors for left ventricular function recovery. One-year, 5-year, 10-year survival rate was 92.9%, 90.2%, 83.8%, respectively.
ConclusionMost of patients with aortic regurgitation and large left ventricle still have indications for surgical treatment, but severe left ventricular dysfunction and ventricular arrhythmia are high risk factors for long-term survival.
To probe the etiopathogenisis of adjacent-segment disease by analyzing the imageology data and cl inical neurological function in patients with anterior cervical discectomy and fusion (ACDF) harvested by long-term follow-up. Methods A retrospective study was performed on 52 patients who had undergone ACDF with perfect documents from January 1990 to April 2003. Of the patients, 45 were males and 7 were females with a mean age of 48.5 years (range from 25 to 72 years). There was the fusion of 10 one-levels, 38 two-levels and 4 three-levels. The cervical anterior-posterior and lateral X-ray, CT and MRI examination were performed before the operation. Cl inical neurological function was recorded by the Nurick score, and this score at 6 weeks after the operation was compared with the later follow-up. In the radiological examination, the motion of adjacent vertebrae and osteophyte formation were reviewed on X-ray and CT, and were converted to the semi-quantitative degeneration score according to the Goffin method. The correlation between Nurick score or degeneration score and the age at operation or fusion levels was compared by Spearman correlation coefficients. The cervical canal sizes of adjacent level and remote level on MRI were reviewed and compared with each other by t test. Results The follow-up period was 3 to 10 years, 6.9 years on average. There was difference in the Nurick score between the 6th week after operation (1.07 ± 0.84) and the later follow up (1.92 ± 1.28) by rank test (P lt; 0.05). There was no correlation between the Nurick score change and the age at operation (r = 0.21, P gt; 0.05) or fused levels(r = 0.30, P gt; 0.05) by Spearman correlation coefficients. There was obvious difference in degeneration score between the 6th week after operation (0.73 ± 0.67) and the later follow up (1.58 ± 1.06), (P lt; 0.01). There was no correlation between the degeneration score change and the age at operation (r = 0.35, P gt; 0.05) or fusion levels (r = 0.38, P gt; 0.05) by Spearman correlation coefficients. The cervical canal size reductions were (1.7 ± 1.1) mm at superioradjacent level, (1.2 ± 0.6) mm at inferior adjacent level and (0.30 ± 0.68) mm at remote level. There was obvious difference between superior or inferior and remote level by t test (P lt; 0.01). The adjacent level developed prominent degeneration together with nerve function change after the fusion operation and displayed correlation between degeneration and nerve function change(r = 0.41, P lt; 0.05). Conclusion The adjacent-segment disease after interbody fusion is produced by multiple factors. The natural progression in adjacent disc, biomechanical natural change resulting from interbody fusion, destruction to l igament structure in front of cervical vertebrae by operation, and bone graft model are important factors not to be ignored.
Objective To observe the changes of disease course and the prognosis of visual acuity of Chinese patients with polypoidal choroidal vasculopathy ( PCV).Methods Visual acuity and fundus photochromes of 20 eyes of 15 consec utive patients with PCV were followed up with a mean of 19.1 months (range from 2 to 64 months), in which the fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA) of 14 eyes of 10 patients were followed up with a mean of 21.0 (range from 3 to 53) months.Results Among the 20 eyes, the visual acuity was more than 0.3 in 5 eyes (25.0%), between 0.1 and 0.2 in 6 (30%) and less than 0.1 in 9 (45.0%). During the follow-up, the visual acuity was improved in 2 (10.0%), stable in 10 (50.0%)), and regressed in 8 (40.0%). Only 1 eye (5.0 %) developed to macula scar. The result of ICGA revealed the polypoidal lesions that were unchanged in 4 eyes(28.6%), regressed in 2 (14.3%), grew in 6 (42.7%), repeatedly grew and spontaneously regressed in 6 (42.7%).Conclusions There is a large variation in the visual prognosis in Chinese patients with PCV. The polypoidal lesions can repeatedly grow and spontaneously regress in the natural course. (Chin J Ocul Fundus Dis，2004，20：8-11)
Abstract： Objective To analyze the mid-term outcomes after correction of type Ⅰ and type Ⅱ persistent truncus arteriosus in all patients operated in our institution over the past 5 years. Methods Between May 2006 and October 2010, 17 patients, mean age 4.7（ 0.7-19.0）years, underwent repair of truncus arteriosus（ type Ⅰ in 13 and type Ⅱ in 4） in Fu Wai Cardiovascular Hospital. Some other concomitant cardiovascular malformations included truncal valve regurgitation, partial anomalous pulmonary venous connection, mitral regurgitation and atrial septal defect. Their average pulmonary vascular resistance was （4.4±2.2） Wood units detected by cardiac catheterization before operation. Repair with reconstruction of the right ventricular to pulmonary artery continuity was performed using a valved conduit in all 17 patients （aortic homografts in 3, pulmonary homografts in 2, and bovine jugular vein in 12 patients）. Survivors were followed up for assessment of residual heart lesions. Results The early mortality was 5.8% （1/17）. The mean cardiopulmonary bypass time was （165±52） min, mean aortic cross-clamping time was （114±29） min, and mean postoperative ventilation time was （106±148） h. Two patients had pleural effusion after surgery, 2 patients underwent tracheostomy, and other patients recovered uneventfully. The surviving 16 patients were followed up for 0.6-5.0 years. All patients were alive with their original conduit during follow-up. No patient required re-operation for conduit dysfunction after correction. Conclusion Truncus arteriosus remains a challenging congenital heart disease. For patients with type Ⅰ and type Ⅱ persistent truncus arteriosus who have missed their best age for correction, cardiac catheterization should be routinely examined, and the operation should be performed if the pulmonary vascular resistance is under 8 Wood units before operation. Although the short- and mid-term results of surgery are good, more observations are needed to assess its long-term effect.
Abstract: Objective To evaluate surgical strategies for the treatment of acute Stanford type A aortic dissection with involvement of the aortic root. Methods From January 2005 to December 2010, 62 consecutive patients underwent emergency surgical intervention for acute Stanford type A aortic dissection with involvement of the aortic root in Renji Hospital Affiliated to Medical School of Shanghai Jiaotong University. According to different methods for the management of proximal aortic dissection, these patients were divided into 3 groups: group A, aortic valve commissural suspension＋supracommissural replacement of the ascending aorta （SCR）,including 28 patients （20 males and 8 females，mean age 45.2±15.6 years）; group B, partial sinus remodeling+ascending aortic replacement, including 10 patients （7 males and 3 females，mean age 44.6±14.9 years）；group C, Bentall procedure,including 24 patients （17 males and 7 females，mean age 46.2±15.6 years）. Clinical outcomes were compared among the three groups. Results Six patients died peri-operatively and in-hospital mortality was 9.67% （6/62）. Fifty-four patients were followed up, and the mean follow-up time was 27.3±15.7 months. During follow up, 2 patients died, one for lung cancer and the other for unknown reason. One patient in group A underwent CT scan 6 months after surgery which showed aortic root pseudo-aneurysm. Cardiopulmonary bypass time and aortic cross-clamping time of group C were significantly longer than those of group A and group B （274±97 min vs. 194±65 min, 210±77 min, t=22.482, 30.419, P=0.002， 0.122；150±56 min vs. 97±33 min, 105±46 min, t=12.630, 17.089, P=0.000，0.034）. There was no statistical difference in mortality （t=1.352，P=0.516）, incidence of postoperative reexploration for bleeding, acute renal failure and neurological complication （t=0.855, 0.342, 2.281; P=0.652, 0.863, 0.320） among the three groups. Conclusion For patients with acute aortic dissection involving the aortic root, aortic valve commissural suspension+SCR，partial sinus remodeling＋ascending aortic replacement and Bentall procedure may be considered the surgical treatment of choice with respective advantages and disadvantages. Satisfactory clinical outcomes can be achieveed if surgical indications and procedures are properly employed.
ObjectiveTo analyze the long-term efficacy and its influencing factors in the treatment of the permanent atrial fibrillation(AF) using monopolar radiofrequency ablation during concomitant cardiac valve replacement surgery with rheumatic heart disease.
MethodsClinical data of the 116 patients with rheumatic heart disease and permanent AF who underwent modified maze procedure using monopolar radiofrequency ablation and concomitant cardiac valve replacement in the affiliated hospital of Qingdao university from October 2004 to December 2010 were collected and retrospectively analyzed, including 43 males and 73 females with their age of 50.5±7.5 years. Electrocardiogram (ECG) with 12-lead and echocardiography data, as well as the related complications, cardiac function and life quality were collected at the time of the immediately after the operation, discharge from hospital, 3 months, 6 months, 1 year postoperatively and every year after the operation. Patients were divided into eliminating group of AF (including sinus rhythm and nodal rhythm) and AF group according to the results of the ECG at the time of the ending follow-up. In the eliminating group of AF, there were 52 patients (16 males, 36 females) with their age of 48.4±7.3 years, and in the AF group, there were 50 patients (22 males, 28 females) with their age of 51.9±7.1 years. Analyzed the difference of the related factors between the two groups using statistical methods and tried to find the factors affecting the long-term clinical efficacy of the operation.
ResultsThree patients died in hospital (one died of the hemolysis, acute renal insufficiency and hyperkalemia. One died of the multiple organ dysfunction syndrome caused by the acute renal insufficiency. And the other one died of the multiple organ dysfunction syndrome caused by the repetitive ventricular tachycardia and ventricular fibrillation on the day of the automatic discharge). Three patients died during the follow-up (one died after the reoperation because of the perivalvular leakage in other hospital, and the causes of death in the two others could not be catched). One patient occurred cerebral embolism, and the other one occurred cerebral hemorrhage in the af group during the follow-up. There was statistical significance between two group at the aspects of age, preoperative AF duration, preoperative left atrium diameter, time of the cardiopulmonary bypass and time of the cross-clamp ascending aorta. In multivariate analysis, age and preoperative left atrium diameter are risk factors affecting the long-term efficacy.
ConclusionThe treatment of the permanent atrial fibrillation using monopolar radiofrequency ablation concomitant cardiac valve replacement with rheumatic heart disease is effective and has good long-term efficacy. The factors of affecting the long-term clinical efficacy are the patient's age and the diameter of left atrium.
Objective To investigate the specific variables and influence factors of Harris scores in follow-up data of patients with internal fixation of femoral neck fracture. Methods From May 1999 to May 2004, 99 cases of femoral neck fracture receiving close reduction with cannulated screw and having complete follow-up data were evaluated in terms of age, sex, type of bone fracture (Garden classification), reduction time, reduction qual ity (Garden indicators), time of full weight-loading, removal of internal fixation, traction before operation, side of bone fracture, necrosis of femoral head, duration of follow-up and Harris score during follow-up period. Univariate and multivariate were analyzed by SPSS14.0 and SAS8.2. Results P-P probabil ity plot and normal test revealed the Harris scores were non-normal distribution (W=0.757 09, P=0.000 1). By nonparametric test in univatiate analysis, the following variables in Harris scores were of statistic significance: the time of reduction (U=— 2.289, P=0.022), the Garden classifaction (H=16.943, P=0.001), the time of full weight-bearing (U=— 3.069, P=0.002), the qual ity of reduction (U=— 3.448, P=0.001) and the necrosis of femoral head (U=— 4.723, P=0.000).By the analysis of correlation, the following variables in Harris scores were of statistic significance: Garden classification(rs=— 0.412, P=0.000), the time of reduction (rs=— 0.231, P=0.021), the qual ity of reduction (rs=— 0.348, P=0.000), the time of full weight-bearing (rs=— 0.310, P=0.002), and the necrosis of femoral head (rs=— 0.477, P=0.000). By the univariate logistic regression analysis, the following variables in Harris scores were of statistic significance: Garden classification (P=0.000 1), the time of reduction (P=0.012 6), the qual ity of reduction (P=0.000 3), the time of full weight-bearing (P=0.003 2), the traction before operation (P=0.049 2) and the necrosis of femoral head (P=0.000 1). By the multivariate logistic regression analysis, the influence factors of Harris scores rank included the necrosis of femoral head (P=0.000 1), the time of reduction (P=0.028 2), and Garden classification (P=0.000 7). Conclusion Harris scores is of non-normal distribution, and the necrosis of femoral head is the most important factor influencing the function after applying internal fixation with cannulated screws to femoral neck fracture.
ObjectiveTo evaluate the clinical features of 18 cases of juxtapapillary capillary hemangioma.MethodsIn 18 cases of 18 cases of juxtapapillary capillary hemangioma,the clinical datd of 19 eyes,the results of funds fluorescein angiography(FFA) of 16 eyes ,and the follow-up observation of 7eyes were retrospectively analyzed.ResultsIn 18 cases,the sex retio of male and female is 1:2 with the average age of 28.9 years.Peripheral retinal angioma was found in 3 cases(4eyes). In19 eyes,thr center of hemangioma was located beyond the rim of optic,most of which was in inferotemporal quadrant of the optic (7/19) with the size of 1-2.5 disc diameter (DD).Most of the tumors were red in colour (12/19).In the result of FFA of 16 eyes ,wash-out at the late phase was found in 13 eyes.decreased acuity was found in all 7 cases that were followed up more than 12 months (including 5 cases treated by laser photocoagulation).retinal detachment did't occur in 6 cases without exudative retinal detachment after being follow-up for 54.5 months of the average term.ConclusionMost of the juxtapiallary capillary hemangioma are orange or red oval tumors.The center of hemangioma are located beyond the rim of the optic.The patients often complain gradually decreased visual acuity when they are in prime of their life with exudation and edema in different degree around the tumor,FFA is helpful for the diagnosis and differential diagnosis of this disease.(Chin J Ocul Fundus Dis，2004，20：1-4)
Objective To summarize our clinical experience of endovascular repair of aortic pseudoaneurysms，andexplore the etiology of the disease，treatment indications，and early and midterm results of the procedure. Methods From November 2009 to May 2012，52 patients with aortic pseudoaneurysms received endovascular aortic repair （EVAR） in FuWai Hospital. There were 44 male and 8 female patients with their age of （53.8±13.5 ） years. Their onset syndromes includedchest or back pain in 46 patients and hoarseness in 5 patients. There were 23 acute patients and 29 chronic patients. Aortic pseudoaneurysms located at the descending thoracic aorta in 51 patients and the abdominal aorta in 1 patient. The meandiameter of the aortic pseudoaneurysms was （45.1±33.8） mm. All the patients were diagnosed using enhanced CT scan of the aorta. Three patients received emergency EVAR. All the patients received EVAR through the femoral arteries under general anesthesia. Forty-six patients underwent isolated EVAR，5 patients received hybrid technique for EVAR via the neck，and 1 patient received hybrid technique including EVAR and total arch replacement via median sternotomy under normothermia. The average diameter of stent-grafts was （34.2±3.3） mm and the average length was （157.7±20.3） mm. Enhanced CT scan of the aorta was performed before discharge，3 months and 1 year after EVAR during follow-up. Results There was no in-hospital death and EVAR was 100% successful. All the patients （100%） were followed up for 1-31 （12.6±7.9）months after discharge. Their chest or back pain symptoms all significantly improved. Their hoarseness improved too duringfollow-up. One patient’s hoarseness disappeared early after EVAR but recurred 5 months after EVAR. Enhanced CT scan showed enlargement of the stent-graft without endoleak. One patient underwent emergency EVAR for sudden onset of massivehemoptysis，recovered well before discharge，and was readmitted to hospital 5 months after EVAR because of fetid sputum and hemoptysis，who was diagnosed as Behcet’s disease and cured after anti-infection and immunosuppressive therapy. One patient had recurrent fever before and 6 months after EVAR and was cured by antibiotic therapy. Intraoperative angiographyshowed trivial typeⅠendoleak in 4 patients right after stent-graft deployment，which disappeared in enhanced CT scan 3-6 months after EVAR. Intraoperative angiography showed no endoleak in all the other patients，and their enhanced CT scans 3 months and 1 year after EVAR showed complete sealing between the stent-grafts and the aortic wall，thrombus in the pseudoaneurysm sac and decreased diameters of the pseudoaneurysms without endoleak. Two patients had hemiplegia 1 dayand 6 days after EVAR respectively，1 patient was cured and discharged and the other patient survived with hemiplegicsequelae. One patient with an abdominal aortic pseudoaneurysm died of sudden onset of cerebral infarction at home 3 monthsafter EVAR. Conclusions Endovascular repair of descending aortic pseudoaneurysms is safe and effective with good early and midterm results，and longer follow-up is needed for its long-term outcomes. Individualized treatment plan is basedon the location of the pseudoaneurysms. Preoperative meticulous medical history and physical examination are both importantfor the differentiation of the etiology of aortic pseudoaneurysms. Postoperative treatment based on the etiology and close follow-up are also needed to ensure long-term results.
