ABSTRACT
Objective:To evaluate the safety and efficacy of n-butyl cyanoacrylate (NBCA) in treating great saphenous vein(GSV) incompetence.Methods:60 patients (60 limbs) with GSV incompetence were randomly divided into NBCA glue group (30 cases) and radiofrequency ablation(RFA) group in 30 cases. The clinical outcomes, venous clinical severity score(VCSS), and quality of life using the Aberdeen varicose vein questionnaire(AVVQ) were evaluated. The primary endpoint is the occlusion rate of GSV at 3 months after surgery.Results:For the two groups, the occlusion rate of GSV was 100% immediately after surgery and at 3 months follow-up. AVVQ and VCSS were improved in the two groups( P<0.05). In terms of complications, the NBCA group had scleroma in 3 cases, pain and skin redness in 1 case respectively, but no ecchymosis and numbness. In the RFA group, numbness occurred in 1 case, skin redness in 2 cases, scleroma in 3 cases, ecchymosis and pain in 4 cases respectively. The incidence of ecchymosis and total complications in the NBCA group was significantly lower than that in the RFA group( P<0.05). No DVT or other adverse event occurred in both groups. Conclusion:NBCA and RFA have the same short-term closure rate. Furthermore, the NBCA treatment requires less equipment, no use of tumescent anesthetic, and has lower incidence in terms of complications than that of RFA.
ABSTRACT
Objective:To investigate the imaging characteristics of uncomplicated acute type B aortic dissection (uATBAD) and the short-term and mid-term outcomes treated with thoracic endovascular aortic repair (TEVAR).Methods:One hundred and forty uATBAD patients treated by TEVAR at Zhejiang Provincial People's Hospital from Jan 2015 to Aug 2021 were retrospectively analyzed. Patients were divided into non-high-risk characteristics group (uATBAD group, 22 cases) and high-risk characteristics group (high-risk uATBAD group, 118 cases) according to the presence or absence of high-risk characteristics. The clinical and follow-up data were analyzed, and the incidence of complications, re-intervention rate, and mortality in the perioperative period and 5-year follow-up were evaluated.Results:The aortic diameter, false lumen diameter and the proportion of laceration in lesser curvature in the high-risk group were higher than those in the non-high-risk group ( P<0.05). There was no significant difference in the incidence of perioperative complications and 30 day mortality between two groups ( P>0.05). The follow-up time ranged from 6 to 83 months (mean 38.3 months). The 5-year mid-term follow-up showed that there was no significant difference in the incidence of aorta-related complications, re-intervention rate, and mortality between two groups ( P>0.05). Conclusions:The imaging characteristics of different typing uATBAD were significantly different. The short- and mid-term clinical effects of TEVAR were similar between the two groups.
ABSTRACT
Objective:To investigate thromboprophylaxis of patients with COVID-19.Methods:Clinical data of 31 patients with COVID-19 in Zhongnan Hospital of Wuhan University was analyzed retrospectively, including basic information, clinical characteristics, examination results, therapy and Padua scores. 5G remote ultrasound diagnosis system was used in the ultrasonography of lower limb vein, inferior vena cava and the heart. According to the patient′s status, the thromboprophylaxis was established, and the incidence of venous thromboembolism (VTE) was observed.Results:There were 20 cases of general types and 11cases of severe types. All patients underwent dynamic assessment and thromboprophylaxis. Basic prevention was applied in 28 cases and mechanical prevention was used in 3 cases. There was no VTE event in all patients during hospitalization.Conclusions:Prevention and monitoring of VTE is an important part of the treatment of patients with COVID-19, which can effectively reduce the incidence of lower extremity deep vein thrombosis and fatal pulmonary embolism in isolation ward.

ABSTRACT
BACKGROUND:Bone cement has certain toxic effects on the human body. The probability of renovation is high after bone cement total hip arthroplasty. It is reported that the long-term effect of cementless total hip arthroplasty is apparently better than bone cement total hip arthroplasty, and can be renovated conveniently. OBJECTIVE:To investigate the clinical effect of cementless total hip arthroplasty on hip joint disease, and to compare the difference between unilateral replacement and bilateral replacement. METHODS: Clinical and folow-up data of 233 patients (280 hips), who were treated with cementless total hip arthroplasty in the Department of Orthopedics, Wuzhou Worker’s Hospital, Seventh Affiliated Hospital of Guangxi Medical University from July 2007 to December 2013, were retrospectively analyzed. According to the replacement program, they were divided into unilateral replacement group (n=186) and bilateral replacement group (n=47). Harris score of hip joint, visual analog scale score of thigh pain, the excelent and good rate of hip joint during final folow-up and complications were compared between the two groups before replacement, at 6, 12 and 24 months after replacement. RESULTS AND CONCLUSION:No significant difference in Harris scores was detected before replacement, at 6, 12 and 24 months after replacement (P > 0.05). Harris score was significantly higher at 6, 12 and 24 months after replacement compared with that before replacement in both groups (P 0.05). No significant difference in the visual analog scale score was seen before replacement, at 6, 12 and 24 months after replacement (P > 0.05). Visual analog scale scores were significantly lower at 6, 12 and 24 months after replacement than that before replacement in the two groups (P 0.05). These findings confirm that the effects of cementless total hip arthroplasty for hip joint disease are evident, can effectively restore hip joint function. No significant difference was detected between unilateral replacement and bilateral replacement. Strict replacement operation and matching of prosthesis and medulary cavity can effectively reduce thigh pain after replacement.

ABSTRACT
Objective To evaluate surgical indications and method for regional pancreatoduodenectomy combined with blood vessel reconstruction. Methods Forty-four patients underwent pancreatoduodenectomy combined with superior mesenteric vein and portal vein(smv-pv) resection and reconstruction between April 1994 and March 2001.Among them superior mesenteric artery (SMA) and hepatic artery (HA) were reconstructed in 4 and 2 cases, respectively. Partial resection of the anterior wall of the inferior vena cava was performed in one case for tumor invasion. Results The overall mortality was 7.1%,with no complications. The resected endothelium or margins of the blood vessel and pancreas were microscopically tumor free in all cases. Histological specimen examinations demonstrated adenocarcinoma of pancreas head in 43 cases, neuroendocrine adenocarcinoma was diagnosed in one case. Patients were followed-up from 3～87 months with 2 cases lost after PV/SMV for pancreatoduodectomy. Six patients have survived more than 5 yearsand 21 cases more than 3 years. Conclusion Regional pancreatoduodenectomy combined with reconstructionof blood vessel could increase tumor resection rate in properly selected patients and could be performed safely without increased morbidity and mortality.
