Objective To evaluate the TriVex system in the treatment of varicose veins of lower extremities,focusing on postoperative complications and management.Methods Clinical data of 108 patients (146 legs) of varicose veins of the lower extremity undergoing TriVex procedure were retrospectively analyzed.Deep veinons patency was verified in all patients by preoperative sonography.Above knee stripping of the great saphenous vein was done first when necessary.The below knee phlebectomy of the side branches was done with the new system (Trivex System/Smith and Nephew).Postoperative patients were followed-up,and results were evaluated.Results Procedure was successful in all cases.98 cases were followed up for 1 ～ 24 months.The mean operation time per leg was (34±8) minutes.Complications were as following:26 legs (17.8%) developed postoperative hematoma which was healed by conservative therapy including two cases in which the tension seroma,which was successfully managed by puncture aspiration.Transien skin numbness or paraesthesia developed in 13.0% (19/146).Subcutaneous induration in 11.6%(17/146) cases.Residual varicose and recurrence in 3.4% (5/146).Incision related complications developed in 4.8% (7/149) cases.Conclusion Transilluminated powered phlebectomy (TriVex) is a safe and effective cosmetic procedure for less invasive varicose vein surgery.

BACKGROUND: Surgical guides designed based on a three-dimensional cone-beam CT (CBCT) model have been reported. However, CBCT cannot remodel fine soft tissue such as gums, and it can only be used to design a simple dental retainer with relatively poor stability. OBJECTIVE: To establish a high-precision three-dimensional (3D) integrated maxillodental model by matching CBCT model with 3D digital maxillodental model using 3D automatic registration method, based on which, we designed and manufactured individualized miniscrew surgical guides. METHODS: CBCT maxillodental models and laser-scanned dentition models obtained from six malocclusion cases were matched and overlapped using the 3D automatic registration method to fabricate the 3D integrated maxillodental model. Then, we accurately positioned and virtually implanted a micro-implant into the 3D integrated maxillodental model. Subsequently we prepared a high-precision individualized resin surgical guide by rapid prototyping technology. The inner diameter of the guide track was detected by a vernier caliper. Patients tried on the resin surgical guide, and then occlusion condition, guide seating and retention were detected. RESULTS AND CONCLUSION: Due to the high-precision registration of the model, all the resin surgical guide plates were suitable. The plate retention was enhanced after tooth clinching, and all the patients felt comfort when wearing the surgical guide plate, with no compression or other discomforts. The inner diameter of the guide track was (1.79±0.23) mm, and the measurement error was not statistically significant (P >0.05). These findings demonstrate that the high-precision surgical guide plate based on the high-precision 3D integrated model can provide the foundation for further investigations on the clinical application of surgical guides.

PURPOSE: Insulin resistance plays a role in the development of dementia and hypertension. We investigated a possible relationship between cognitive impairment and insulin resistance in elderly Chinese patients with primary hypertension. MATERIALS AND METHODS: One hundred and thirty-two hypertensive elderly patients (>60 years) were enrolled in this study, and assigned into either the cognitive impairment group (n=61) or the normal cognitive group (n=71). Gender, age, education, body mass index (BMI), waist hip ratio (WHR), total cholesterol (TC), triglyceride (TG), C-reactive protein (CRP), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), creatinine (Cr), fasting plasma glucose (FPG), fasting insulin (FINS), homeostasis model of assessment for insulin resistance index (HOMA-IR), systolic blood pressure, diastolic blood pressure, smoking history, atherosclerosis and the proportion of uncontrolled hypertension were compared between the two groups. Multi-factorial logistic regression analysis was performed. RESULTS: No significant differences were found in gender, age, TC, CRP, HDL-C, LDL-C, Cr, BP, smoking history, atherosclerosis and the proportion of uncontrolled hypertension between the two groups. The cognitive impairment group had lower education levels, and higher BMI, WHR, TG, FPG, FINS, and HOMA-IR levels than the control group. Logistic regression analysis revealed the levels of education, BMI, WHR, and HOMA-IR as independent factors that predict cognitive impairment in patients. CONCLUSION: Our study demonstrates that poor education and increased BMI, WHR, and HOMA-IR are independent risk factors for cognitive impairment in elderly patients with hypertension. Insulin resistance plays an important role in the development of cognitive impairment in primary elderly hypertensive patients.

OBJECTIVETo evaluate current diagnosis and therapeutic effect and outcome of diffuse axonal injury (DAI) in 169 patients.

METHODSThe data of 169 DAI patients treated in the Second, Sixth, Eighth and Ninth Hospitals of Shenzhen and Shekou Hospital from January 2001 to January 2005 were collected. The imaging features, classification, GCS (Glasgow coma scale), treatment and outcome of the 169 patients were retrospectively analyzed.

RESULTSThe simpler the imaging features, the closer the focus of DAI to the periphery of hemisphere and the higher the GCS score, the better the prognoses of DAI patients will be.

CONCLUSIONSThe prognoses of DAI patients are closely related to the imaging features and classification, GCS and clinical treatment.

BACKGROUND: There are many studies on Modic changes in patients with lumbar degenerative disease and low back pain. However, few studies facus on epidemiological distribution and related factors of Modic changes in cervical spine, and its epidemiology and influencing factors remain unclear.OBJECTIVE: To study the morbidity and distribution of Modic changes in patients with cervical and shoulder pain and its correlation with gender, age and cervical degeneration. METHODS: Totally 430 patients admitted in the Second Affiliated Hospital of Inner Mongolia Medical University and undergoing cervical MRI and CT examination due to neck and shoulder pain between December 2014 and December 2016 were retrospectively analyzed, involving 197 males and 233 females, aged 19-78 years (mean age: 50.3 years). The morbidity and segmental distribution of Modic changes and its correlation with age, sex, cervical intervertebral disc degeneration and facet joint degeneration were analyzed. RESULTS AND CONCLUSION: (1) Among 2 150 disc segments of 430 patients, 348 segments (16.2%) of 67 patients (15.6%) appeared with Modic changes:73(3.4%)segments were type I,243(11.3%)were type II,and 32(1.5%)were type III.(2)By application of chi-square test, Modic changes were most common at the C5/6segment; older than 40 years and Pfirrmann disc degeneration grade III were relevant factors, while gender and facet joint degeneration were not.

BACKGROUNDBudd-Chiari syndrome (BCS) is a posthepatic portal hypertension caused by the obstruction of the lumen of the hepatic veins or the proximal inferior vena cava (IVC). This study aimed to evaluate the clinical experience of interventional therapy for Budd-Chiari syndrome.

METHODSIVC venography was carried out first, the obliteration or stenosis in the IVC was opened or dilated with the hard guided wire or Rups100 puncture needle and balloon, then a stent was routinely implanted for the type of obliteration or stenosis.

RESULTSThe procedure was successful in 821 out of 903 cases including IVC intervention in 760 cases, and hepatic vein intervention in 61 cases. An IVC stent was used in 517 cases and hepatic vein stent in 19 cases. There were no pulmonary embolisms, but acute renal failure occurred in eight cases, hepatic coma in two cases and acute heart failure in 43 cases. Two patients died in this group and five cases were complicated with acute IVC thrombosis. Follow up of 7 to 124 months was made in 679 cases with recurrence found in 59 cases.

CONCLUSIONSInterventional therapy is safe and effective with a fast recovery for most types of BCS. It is gradually becoming the first therapeutic choice.
