0.05). ConclusionsWhen varicose veins of the lower extremity with deep vein insufficiency exists, patients should undergo high ligation and stripping of the great saphenous vein, additional correction of the deep vein reflux provides no further effect.
2.Application and progress of surgical nutrition

Nutrition support is extensively used in many clinical fields. The rest energy requirement in Chinese is only 5021~5858kJ/d.In our country 40% to 50% of hospitalized patients need nutrition support.In nutrition support,attention should be paied to :(1)The energy giving to the patient should be appropriate;(2)hormone resistance;(3)immunonut rition.

China is one of the countries with most serious natural disasters lose all over the world.Natural disasters are a public emergency.Human society can't avoid the natural disasters today,so the global target of a struggle is to reduce the loss of natural disasters.The natural disasters loss will be reduced to a minimum,once the system is established of medical rescue and emergency management by the government.

0.05). Neuralgia of the lower limb was complicated in 3 (8%)cases. 31 cases were followed up from 3 months to 9 years. 24 out of the 26 patients experincing immediate post-CLS relief remained asymptomatic, and 2 suffered symptom deterioration necessitating major amputation. ConclusionsCLS is a simple procedure with less complication offering an alternative for the treatment of lower limb ischemia.

AIM:To evaluate the effects of atorvastatin on nitric oxide(NO),endothelin-1(ET-1)and myocardial no-reflow in a rabbit model of acute myocardial infarction and reperfusion(AMI/R). METHODS:Twenty-four rabbits were randomized into 3 groups:8 in AMI/R group,8 in atorvastatin-treated group(5 mg?kg-1?d-1)and 8 in sham-operated group. Animals in the former two groups were subjected to 60 min of coronary occlusion followed by 120 min of reperfusion. Data on haemodynamics were collected. NO in blood sample,and in normal,and in infarcted reflow and no-reflow myocardium were evaluated respectively by nitrate reductase method. The levels of ET-1 in blood sample,and in normal,infarcted reflow and no-reflow myocardium were determined by radioimmunoassay. RESULTS:(1)Compared to the baselines,the heart rate(HR),systolic blood pressure(SBP),diastolic blood pressure(DBP),left ventricular systolic pressure(LVSP),maximal rate of increase and decline in left ventricular pressure(?dp/dtmax)and cardiac output(CO)in AMI/R and atorvastatin-treated groups were significantly declined,whereas left ventricular end-diastolic pressure(LVEDP)was increased after 60 min of coronary occlusion and 120 min of reperfusion(P

Objective To evaluate the complicatio ns after thrombectomy for deep vein thrombosis (DVT) of the lower extremity. Methods Thrombectomy was under taken for 143 patients using Fogarty catheter, then local thrombolysis and antic oagulation was undertaken by a indwelling catheter in the great saphenous vein. Results The total recurren ce rate of DVT was 12.6%(18/143), whereas the early recurrence rate without loc al thrombolysis and anticoagulation was 29.8%(14/47). The recurrence rate was 1 8.9%(14/74) against the background of Cockett syndrome, and 5.8%(4/69) withou t Cockett syndrome. Other complications included lymphatic fistula in 4 cases (2 .8%), pulmonary embolism, vena cava thrombosis, massive haemorrhage, and incisi onal infection in one each, death ensued in 3 (2.1%). ConclusionsThe recurrence rate of DVT could be low ered by management of the stenosis or occlusion of common iliac vein and local thrombolysis and anticoagulation. Thrombectomy should be the first choice of the rapy for DVT.

Objective To study the effect of thoracoscopic sympathectomy and/or chemical lumbar sympa- thectomy performed on patients with Raynaud disease. Methods Five patients, 1 male,4 females, aged from 30 to 65(mean 45. 3 ). Raynaud phenomenon appeared only on both hands in one patient, only on feet with a toe gangrene in another one , the other 3 cases on all limbs. Thoracoscopic symathectomy was performed for those whose hands were af- fected and chemical lumbar sympathectomy(12-3 ) was pererformed for those whose feet were affected. Results All patients were followed up from 12 to 48 months(mean 24 months). All experinced improvement with hands warm and satisfactory results after thoracoscopic sympathectomy. However, the original symptoms reccurred in two patients after postoperatire six months. All 4 patients performed chemical lumbar sympathectomy experienced improved symptoms with feet warm and satisfactory results and the symptoms did not recur up to now. The sympathectomy showed different results for hands and for feet. Conclusions Thoracoscopic sympathectomy for hands affected by Raynaud disease has efficiency temporarily, but is not satisfactory. The chemical lumbar sympathectomy for the feet affected by Raynaud disease has dramatically disappearence of symptoms and the results are very good

Objective To investigate the therapeatic effects of chemical thoracic sympathectomy (CTS) for Raynaud disease. Methods A niddle was injected into the first or second thoraic vertebra from back. A X-ray examination was performed to definite the position of the niddle tip. One millilitre of urographine was injected to determine if it was infused into thoracic cavity. If not, 2 ml of 5% phenol was injected and the niddle was removed. Results Within 10 minutes both pairs of the hands of the two patients with Raynaud's disease turned into flushing and warm from pallor and cool after CTS. Ice-water test changed to negative. Conclusions CTS is of simple, microinvasive and low cost procedure for Raynaud's disease.

Objective To report an improved method, color-ultrasonography-guided inferior vena cava (IVC) filter placement, for preventing the pulmonary embolism (PE) caused by the deep venous thrombosis (DVT). Methods Color-ultrasonography-guided IVC filter insertion was performed in 9 patients with DVT of lower limb, 1 of which also had PE accompanied with at the time of admission. Out of the 9 patients, 5 patients underwent embolectomy immediately after the filter placement while the other 4 patients were treated conservatively. Results The placements were all completed successfully. Follow-up observations for 1~7 months (mean 2 months) found no complications or occurrence of PE. No recurrence of PE was found in the patient already with PE. Conclusions The color-ultrasonography-guided IVC filter placement can effectively prevent PE caused by DVT. The method is suitable for severe, immovable patients, as well as patients with renal insufficiency and being allergic to intravenous contrast, and is safe, convenient, cheap and prone to popularization.

Objective To study the causes, prevention and treatment of secondary thrombosis after vena cava filter placement. Methods We summarized the clinical experience regarding 7 cases of secondary thrombosis of the inferior vena cava from December 2001 to June 2004 in this hospital. Results Two patients underwent thrombectomy, 1 patient received interventional thrombolytic therapy, and the rest of 4 patients received conservative treatment. All the treatment had obtained good results. No pulmonary embolism took place in the study. Conclusions Thrombosis secondary to filtration can be completely prevented by adhering strictly to the indications of filter placement and conducting supplementary anticoagulation therapy. Interventional therapy is the first choice for the treatment of secondary thrombosis after filter placement.
