目的研究置管溶栓联合球囊扩张导管碎栓治疗下肢深静脉血栓形成（DVT）的疗效及安全性。 方法回顾性分析2011年9月至2015年1月本院收治的82例急性下肢DVT患者的临床资料。将患者分成两组：A组行单纯经导管直接溶栓（CDT）治疗，共32例，其中男10例、女22例，平均年龄（56±15）岁；B组行CDT联合机械碎栓（球囊扩张导管碎栓）治疗，共50例，其中男18例、女32例，平均年龄（57±17）岁。比较2组治疗前后静脉通畅率、静脉通畅度评分、健侧和患侧下肢周径差，比较2组尿激酶用量及溶栓导管留置时间，以出血并发症、肺栓塞的发生率评价治疗的安全性。 结果2组共82例患者完成溶栓及碎栓疗程，B组较A组溶栓时间更短，A组平均9（7，12）d；B组平均5（4，7）d，2组差异有统计学意义（P<0.01）；B组较A组尿激酶用量更少，A组平均7.250（6.355，8.255）×106 U，B组平均4.925（3.715，5.810）×106 U，2组差异有统计学意义（P<0.01）；B组治疗后的静脉通畅度评分显著优于A组，A组65.0%（40.5%，86.5%），B组为100%（90%，100%），差异有统计学意义（P<0.01）。治疗后2组出血并发症发生率差异无统计学意义（P=0.0976）。2组患者随访时间3～18个月，A组随访率50.0%，B组随访率58.0%，均未发生肺动脉栓塞。 结论在下腔静脉滤器保护下，CDT联合球囊扩张导管碎栓治疗急性下肢DVT较单纯CDT治疗，溶栓效果好、尿激酶用量少、不增加肺栓塞及出血发生率。
Objective To explore the effect of endovascular treatment guided by ultrasonography combined with portosystemic shunts on the patients with Budd-Chiari Syndrome （BCS）.Methods The clinical data of 136 patients with BCS treated by balloon angioplasty and stent implantation guided by Doppler ultrasonography in our hospital from January 1995 to January 2011 were retrospectively analyzed.After balloon angioplasty,53 patients were treated by inferior vena cava （IVC） stent implantation and 31 patients with hepatic venous occlusion underwent portosystemic shunts （PSSs） at one week after endovascular treatment.The long-and short-term effects after treatment were studied.Results After endovascular procedures,the IVC pressure of patients significantly decreased （P＜0.01）,while IVC diameter, flow velocity in the lesion,and right atrial pressure of patients showed significant increase（P＜0.01）.Slight heart dysfunction appeared in 13 cases of patients.After shunting,acute pancreatitis occurred in 3 cases, and 1 patient died of upper gastrointestinal hemorrhage on the 10 d after PSSs.Doppler ultrasonography for IVC and shunt vessels showed：the swollen liver and spleen lessened on 3d after endovascular procedures.The swollen liver lessened 2-7cm （mean 5.5cm）,swollen spleen lessened 3-8cm （mean 5.8cm）, and the time of ascites disappearance was 3-60d （mean 14d）.All the patients were followed up for 1 month to 15 years with an average of 3 years.Restenosis of the distal part of stent was found in 1 patient in 2 years after operation, hepatic vein occlusion occurred in 1 case in 1 year after treatment,hepatocellular carcinoma occurred in 1 patient in 3 years after stent implantation,and 1 patient died of C type hepatitis after 1 year,and 5 out of 6 cases of patients with infertility had babies after 1 year.All patients had no stent migration or occlusion of shunts and the symptoms of portal hypertension were obviously relieved.Conclusions Endovascular treatment guided by Doppler ultrasonography is a convenient,safe,and effective method for BCS.Portosystemic shunts are commended to patients with hepatic venous occlusions.The above mentioned methods provide a feasible and effective means for IVC stenosis and short segment occlusion with hepatic vein occlusion of BCS.
In order to observe the absorption of the fat solube vitamine afer operative treatment of the congenital biliary dilation(CBD),the plasma fat soluble vitamin A,D and E were determined in 57 cases of CBD at the postoperative stage and 51 cases of normal children as control.The normal values of vitamin A,D and E was 576.25±170.93ng/ml,13.21±2.20ng/ml and 7.34±1.96ng/ml respectively in control group versus 501.59±120.64ng/ml, 11.66±1.81ng/ml and 6.16±1.18ng/ml respectively in the postoperative group of CBD.The differences were significant for a long period of about 10 years,and gradually disappear after that to approach or near the normal level.Therefor,the radical operation of CBD may affect the absorption of the fat soluble vitamins.
From Jan. 1, 1990 to Dec. 30, 1994, 38 patients with mammary duct ectasia admited to our hospital, for whom the diagnoses were confirmed by pathological examination of surgical specimens. Intensive literature review was made together with 569 cases of this group were summarized in terms of clinical features of the disease. Tumor-like mass is a most common sign (78.21%), and the other clinical features are: nipple discharge (28.47%), nipple retraction (21.79%), axillary node enlargement (15.82%), skin adhesion (11.25%) and breast fistula (3.87%). Surgical excision of the mass is the unique effective treatment of chioce. 24 out of 38 cases were misdiagnosed other than mammary duct ectasia. Careful clinical observation and examination may reduce the chance of misdiagnosis.
Objective To explore the distribution of bacteria among community acquired lower respiratory tract infection (LRTI) inpatients with underlying chronic respiratory tract diseases.Methods The clinical data，sputum culture and drug susceptibility results of 212 community acquired LRTI patients who were hospitalized during the period 2001-2005 were retrospectively analyzed.All patients had various underlying chronic respiratory tract diseases.Results A total of 229 strains of pathogens were detected，with the majority being gram negative bacteria.In pathogens of acute exacerbation of chronic obstructive pulmonary disease，gram negative bacteria occupied 73.9%.And Pseudomonas aeruginosa and Klebsiella pneumoniae were the most common pathogens，with each occupying 18.2% and 13.6% respectively.Gram positive bacteria occupied 23.8%，mainly Staphylococcus aureus (10.2%) and Streptococcus pneumoniae (9.1%).In patients with bronchiectasis exacerbated by bacterial infection，86.2% were caused by gram negative bacteria，the top three being，in descending order，Pseudomonas aeruginosa (27.5%)，Haemophilus parainfluenzae (13.7%)，and Haemophilus influenzae (11.8%).Bronchiectasis was the major risk factor of getting Pseudomonas aeruginosa infection (OR=5.590，95%CI 2.792~11.192).The risk factors of getting Acinetobacter baumanii infection were antacid usage within 1 month (OR=9.652，95%CI 2.792~11.192) and hypoalbuminemia (OR=2.679，95%CI 1.108~6.476).For enterobacters infections，including Klebsiella pneumoniae，Enterobacter cloacae and Escherichia coli，the risk factors were antibiotic usage within 1 month (OR=4.236，95%CI 1.982~9.057)，having renal diseases (OR=4.305，95%CI 1.090~17.008) and diabetes mellitus (OR=2.836，95%CI 1.339~6.009).Conclusions Gram negative bacteria were the main pathogens of community acquired LRTI in hospitalized patients with underlying chronic respiratory tract diseases.The pathogens were influenced by underlying diseases，severity of diseases and drug usage history of patients.
