Solitary pulmonary nodule (SPN) is defined as a rounded opacity≤3 cm in diameter surrounded by lung parenchyma. The majority of smokers who undergo thin-section CT have SPNs, most of which are smaller than 7 mm. In the past, multiple follow-up examinations over a two-year period, including CT follow-up at 3, 6, 12, 18, and 24 months, were recommended when such nodules are detected incidentally. This policy increases radiation burden for the affected population. Nodule features such as shape, edge characteristics, cavitation, and location have not yet been found to be accurate for distinguishing benign from malignant nodules. When SPN is considered to be indeterminate in the initial exam, the risk factor of the patients should be evaluated, which includes patients' age and smoking history. The 2005 Fleischner Society guideline stated that at least 99% of all nodules 4 mm or smaller are benign; when nodule is 5-9 mm in diameter, the best strategy is surveillance. The timing of these control examinations varies according to the nodule size (4-6, or 6-8 mm) and the type of patients, specifically at low or high risk of malignancy concerned. Noncalcified nodules larger than 8 mm diameter bear a substantial risk of malignancy, additional options such as contrast material-enhanced CT, positron emission tomography (PET), percutaneous needle biopsy, and thoracoscopic resection or videoassisted thoracoscopic resection should be considered.
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.
ObjectiveTo evaluate early and midterm outcomes of aortic root enlargement (ARE) combined with supra-annular valve implantation for adult patients with aortic stenosis (AS) and small aortic roots (SARs). MethodsFrom January 2007 to July 2011, ARE combined with supra-annular valve implantation was performed for 38 adult patients with AS and SARs in Department of Cardiac Surgery of Beijing Anzhen Hospital. There were 12 males and 26 females with their age of 16-58 (38.6±21.0) years, body weight of 48-78 (58.5±12.0) kg, body height of 153-176 (162.8±12.0) cm and a mean body surface area (BSA) of 1.67±0.32 m2. There were 19 patients with rheumatic AS, 11 patients with congenital bicuspid aortic valve and AS, 5 patients with degenerative AS and 3 patients with AS and infective endocarditis. Preopera-tively, 8 patients were in NYHA class Ⅱ, 29 patients were in NYHA class Ⅲ, and 1 patient was in NYHA class Ⅳ. Aortic annular diameter (AAD) was 15-20 (17.6±2.8) mm and trans-aortic pressure gradient was 53-75 (62.8±10.5) mm Hg. ResultsCardiopulmonary bypass time was 83-145 (112±29) minutes, and aortic cross-clamping time was 58-116 (87±28) minutes. Intraoperative measurement of AAD was 15-20 (17.3±2.6) mm, AAD after ARE was 20-25 (22.6±2.3) mm. AAD after ARE was 12-17 (14.0±2.6) mm larger than AAD before ARE. Actual size of prosthetic valves was 2-3 sizes larger than predicted size without ARE in all the patients. There was no perioperative death or severe complication including bleeding. Length of ICU stay was 12-41 (26±14) hours, and length of hospital stay was 9-15 (12.5±3.2) days. A total of 37 patients (97.4%) were followed up for over 2 years after discharge. All the patients were in NYHA class Ⅰ. Grade 2/6 systolic murmur was heard in 3 patients. Electrocardiogram (ECG) showed significant improvement or complete disappearance of left ventricular hypertrophy in 35 patients, and mild left ventricular hypertrophy in 2 patients. ECG during follow-up didn't show any sign of myocardial ischemia, ventricular arrhythmia or severe atrioventricular block in any patient. ConclusionEarly and midterm outcomes of ARE combined with supra-annular valve implantation for adult patients with AS and SARs are satisfactory, but long-term outcomes of this procedure need further follow-up.
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.
Objective To evaluate the prognosis of retinopathy of prematurity (ROP) following the screening and treatment guidelines of the Chinese Ministry of Public Health. Methods From December 2003 to December 2010, 1379 premature infants diagnosed with ROP were followed by binocular indirect ophthalmoscopy or fundus photography using RetcamⅡ digital camera. For the stage 1 ROP, eyes were followed every 2 weeks until the ROP regressed. For the stage 2 ROP or pre-threshold disease, eyes were followed weekly. If the ROP decreased, eyes were followed every two weeks until the ROP regressed completely. For the stage 3 ROP or acute progressive ROP (AP-ROP), eyes were followed 2-3 times weekly. If the ROP progressed to threshold or type 1 pre-threshold disease, laser therapy was performed within 72 hours. After laser treatment, eyes were followed every 1 -2 weeks. Laser or cryotherapy was conducted when the ROP progressed after first treatment. Scleral buckle and vitrectomy with closed triple incisions was conducted when the ROP progressed to stage 4 and stage 5. The period the infants were followed ranged from 6 months to 2 years (average 152.3 days). ResultsA total of 2758 eyes of 1379 infants were diagnosed with ROP. The gestational age range was 26 . 35 weeks (average 30.6 weeks) and the birth weight of 800-2200 grams (average 1424.6 grams). Four hundred eyes (14.5%) of 206 infants with threshold or type 1 pre-threshold disease were given laser treatment. Three hundred and forty-five eyes (86.2%) completely regressed, and 55 eyes (13.8%) progressed to unfavorable structural outcomes. All 2358 eyes that did not reach threshold or type 1 prethreshold disease regressed completely. The total regression rate of our study was 980%. The incidence of unfavorable structural outcomes was 2.0% including stage 4 in 32 eyes (1.2%) and stage 5 in 13 eyes (0.5%). The retina reattatched in all 6 eyes treated with scleral buckle but macular traction remained at the optic disc. In the 39 eyes treated using vitrectomy with or without lensectomy, the retina reattached completely in 17 eyes at stage 4a. In 15 eyes at stage 4b, the retina reattached completely in 10 and remained detached in 5 eyes. In the 13 eyes at stage 5, the retina reattached completely in 4, and reattached mostly in 1 eye. Conclusion The incidence of severe ROP leading to unfavorable structural outcomes can be effectively reduced by screening and timely treatment.
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.
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 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.
ObjectivesTo investigate the status quo of follow-up services for patients with cervical spondylosis, to explore its influencing factors, and to provide reference for the follow-up management model after postoperative discharge of patients with cervical spondylosis.MethodsA total of 220 patients with cervical spondylosis were selected by using convenient sampling from October 2018 to May 2019, and the general information questionnaire and the follow-up service needs questionnaire were used for the investigation.ResultsThe score of follow-up service content requirement for patients with cervical spondylosis was 54.87±7.56, and the rehabilitation training instruction was the highest. Multiple linear regression analysis showed that the follow-up service content score was influenced by education level [non-standardized partial regression coefficient (b)=3.186, 95% confidence interval (CI) (2.490, 3.882), P<0.001], length of hospital stay [b=5.140, 95%CI (3.914, 6.365), P<0.001], Neck Disability Index [b=1.326, 95%CI (0.189, 2.463), P=0.022], and age [≥75 years as the reference, 45-59 years: b=3.766, 95%CI (0.671, 6.860), P=0.017; 60-74 years: b=4.081, 95%CI(0.849, 7.314), P=0.014]. The method of obtaining follow-up services was mainly based on outpatient follow-up (85.5%), telephone follow-up (50.5%), and established a follow-up service center (40.5%) for discharged patients. The executives were multidisciplinary teams (60.5%) and hospital-community integration teams (48.2%). There were 19.1% of discharged patients who were willing to pay for relevant follow-up services.ConclusionsPatients with postoperative cervical spondylosis have strong demand for post-discharge follow-up services, which are affected by many factors. Medical staff should pay attention to this and develop a personalized follow-up service plan according to patient characteristics to meet different discharged patients and improve the quality of medical services.
