bjective To study the effectiveness of subfascial endoscopic communicating branch vein ablation in treating communicating branch vein insufficiency.MethodsFiftyseven cases of primary lower extremity vein valve insufficiency complicated by communicating vein insufficiency diagnosed by venography and color duplex were treated with subfascial endoscopic communicating branch vein ablation, and their information was analyzed retrospectively.ResultsSwelling was observed in leg of 7 cases after operation, and disappeared within one week spontaneously. Incision infection occurred in 2 cases and skin ambustion happened in 2 cases. Superficial vein varicosis disappeared in all case, skin pigmentatin declined significantly and ulcers healed in 2-3 weeks.Conclusion Subfascial endoscopic communicating branch vein ablation is an excellent choice in treating communicating branch vein insufficiency.
Objective To study the effectiveness of substitute valve at the popliteal vein in treatment of deep venous valve insufficiency of lower extremities. Methods From January 1996 to August 2002, 27 patients were diagnosed having deep venous valve insufficiency of lower extremities by color Doppler and radiography with an average disease course of 17.4 years.All 27 patients had varicose vein, 25 pain, 22 swelling,25 pigmentation in ankle area and 19 chronic ulcerations.Two cases had been treated with great saphenous vein ligation and striping.Averagevein pressure in resting position was (11.00±0.73)kPa,and the ambulatory venous pressure was (9.14±0.68)kPa.All patients were treated with substitute valve at the popliteal vein,and great saphenous vein ligation and stripping, some were treated with subfascial endoscopic perforating veins ablation. Results The average ambulatory venous pressure after operation was (5.94±0.82)kPa,were significantly different from that before operation(P＜0.01). The curative results were satisfactory,and all symptom and physical sign disappeared.After a mean follow-up period of2-6 years,21 cases had satifactory results. Conclusion Substitute valve at the popliteal vein have the value of widespread application.
Objective To explore the correlation between hematocrit and slow coronary flow (SCF) in male patients. Methods We studied 205 patients with angiographically no more than one stenosis lt;40% in each major coronary artery who had admitted to the department of cardiology of the Beijing Anzhen Hospital Affiliated to Capital Medical University from August 2011 to August 2012. According to the level of hematocrit, 101 patients were classified into the trial group whose hematocrit was more 42.9%, while 104 patients into the control group whose hematocrit was no more than 42.9%. Clinical variables were analyzed and compared between the two groups. Results The age was younger in the trial group than the control group, whereas the levels of white blood cell count, mean platelet volume, triglyceride, low-density lipoprotein cholesterol, left anterior descending artery (LAD) and right coronary artery (RCA) TIMI frame count and the proportion of SCF in the LAD were higher in the trial group than in the control group (Plt;0.05). The results of correlation analysis showed that, LAD TIMI frame count (r=0.238, P=0.001), proportion of SCF in the LAD (r=0.206, P=0.003) and RCA TIMI frame count (r=0.209, P=0.003) were positively correlated with hematocrit. The results of multivariate analysis (using logistic regression with adjusted confounding factors such as age) showed that, LAD TIMI frame count (OR=1.031, 95%CI 1.006 to 1.056, P=0.014), proportion of SCF in the LAD (OR=1.919, 95%CI 1.038 to 3.547, P=0.038) were independently correlated with hematocrit. Conclusion The proportion of SCF in the LAD is independently correlated to hematocrit, which suggested that increased hematocrit may contribute to the pathophysiological change of SCF in male patients.
