Observation of curative effect of treatment of varicose veins of lower extremity with polyurethane foam sclerosing agent under fluoroscopic guidance / 中国生化药物杂志

Objective To investigate and analyze the effect of polyurethane foam sclerotherapy on varicose veins of lower extremity under the guidance of fluoroscopy. Methods 90 patients with varicose veins treated in our hospital from February 2015 to May 2017 were selected and randomly divided into the control group and the experimental group, with 45 patients in each group. The patients in the control group were given conventional high ligation and stripping of the great saphenous vein. The patients in the experimental group were treated with fluoroscopic guided polyurethane foam sclerotherapy. The therapeutic effects of the 2 groups were compared and analyzed. Results After operation, 2 patients relapsed in the experimental group, and the recurrence rate was 4.4％. In the control group, 6 patients relapsed. The recurrence rate (13.3％) in the control group was significantly higher than that in the experimental group, with statistical difference. After the corresponding treatment, the intraoperative blood loss in the experimental group was (10.23±1.52) mL, and the bleeding volume in the control group was (32.19±2.34) mL. The bleeding volume in the experimental group was significantly less than that in the control group, with statistical difference. In addition, the average length of stay, length of operation and length of incision in the experimental group were significantly better than those in the control group, with statistical difference. Conclusion The clinical effect of fluoroscopy guided lauromacrogol foam sclerosing agent in the treatment of varicose vein of lower limb is better, the recurrence rate is low, can significantly reduce the amount of bleeding, shorten operation time, has clinical significance.

Outcomes of coronary artery bypass grafting in old patients with diabetes / 中华胸心血管外科杂志

Objective The risk for coronary artery bypass surgery is reported to be increased with age and associated with diabetes. We examined the outcomes of coronary artery bypass grafting (CABG) in patients with diabetes who were older than 70 years of age and evaluate the effect of diabetes on CABG in those patients. Methods From March 2000 to March 2008, the data of 649 patients older than 70 years of age were collected retrospectively and divided into diabetic group or non-diabetic group based on pre-operative diagnosis. The blood glucose level of patients was maintained between 7.0 mmol/L ( 126mg/dl) and 10.0 mmoL/L ( 180 mg/dl) porioporatively. Stats 7.0 was used for statistical analysis. The t test and χ~2 test were used to determine the differences in the numerical variables and categorical variables respectively. Results No statistical differences were observed between the two groups in the baseline variables, such as age [ ( 74.78±3.67 ) years for diabetic group vs. ( 75.00±3.65 ) years for non-diabetic group, P = 0. 4877 ], female patients ( 34.76% vs. 29.22%, P =0. 1663 ), ejection fraction [ ( 57.02±10. 10 ) % vs. ( 58.49±10. 39 ) %, P = 0. 1004 ) ], myocardial infarction history (26.20% vs. 28.35%, P =0. 5795), though there were more left main diseases in the diabetic group (52.41% vs.26.41%, diabetic vs. non-diabetic, P = 0. 0000 ). The overall in-hospital mortality was 6.32% (8.02% in the diabetic group vs. 5.63% in the non-diabetic group, P = 0. 2571 ). The main causes of death were sudden respiratory and cardiac arrest,low cardiac output syndrome ( LCOS), malignant arrhythmia, respiratory failure, renal failure, central nervous system compli-cations, and multiple organ failure. Major post-operative complications were bleeding, atrial fibrillation, plural effusion and pulmonary infection. Post-operative variables, such as EF (0.59±0. 13 in the diabetic group vs. 0. 61±0.15 in the non-dia-betie group, P =0. 1807), re-revascularization due to bleeding (2. 14% vs. 4.76%, P = 0. 1232), blood transfusion (89.84% vs. 84.63%, P = 0.0820) and the administration of vasoactive agent (21.93% vs. 27.71%, P= 0. 1286),were found no significant difference between the two groups. Conclusion Conclusions The early outcomes of CABG in aged patients are acceptable. The surgical consequences in diabetic patients may be similar to those in non-diabetic patients.

The effect of low dose TP-5 after CPB operation / 医学研究生学报

Objectives:To investigate the effect of TP 5 on the immune function and infection rate in patients undergoing cardiopulmonary bypass(CPB) operation. Methods:Ninety four patients were divided into two groups to observe the effect of TP 5 on the immune function and infection rate. Results:The immunological parameters in the TP 5 group was better than the control group, and postoperative infection was prevented. Conclusions:TP 5 can improve patients' cell mediated immunity and reduce infection rate.

Endovascular Stenting for the Treatment of Thoracic Aortic Aneurysm / 中国微创外科杂志

Objective To investigate the indications and efficacy of endovascular stenting for the treatment of thoracic aortic aneurysm.Methods From March 2005 to October 2008,21 patients with Stanford type B aortic dissection,5 cases of pseudoaneurysm,and 2 patient with intramural hematoma complicated with ulcer of the aortic wall were treated by endovascular stenting under general(2 cases) or local(26 cases) anesthesia in our hospital.Medtronic Talent stent was employed in 10 cases,Medtronic Valiant stent was used in 12,and microinvasive straight-type stent was used in 6 patients.Results The operation was completed successfully in all of the 28 cases.Angiography showed that the gaps in the aorta were closed without endoleak.No patient had chest pain or neurological complications.The patients were discharged in(4.5?1.1) days(range 3-7 days).Five patients developed fever after the operation and were cured by indomethacin in one month.One week after the surgery,in 21 cases,CT scan showed enlarged aortic dissection,improved blood supply,thrombus in the false lumen of the thoracic aorta,and a false lumen in the abdominal aorta.In the 5 cases with pseudoaneurysm,CT scan confirmed that the rupture was closed with thrombus being detected in the lumen.The aortic ulcers that were detected in the 2 cases,who had intramural hematoma,were covered by the stents.Of the patients,a follow-up of(21.3?10.2) months(range 1-40 months) was available in 23 patients,who had no complications during the period.Conclusions Endovascular stenting is a simple,safe and effective method for Stanford type B aortic dissection,pseudoaneurysm,and intramural hematoma,resulting in quick recovery,less complications,and short hospital stay.
