Methods： Fifty-six cases of simple atherosclerotic occlusive disease of lower extremity were divided into 3 types according to the location of occhision, including 17 cases of abdominal aorta-iliac artery, 18 cases of iliac-femoral artery, and 21 cases of inferior popliteal artery. Catheter and guide wire combined with blunt dissection and subtle banding were used to dredge the occluded vessels, and stents were implanted when interlayer appeared. Results： After the treatment, 46 cases of occlusion were dredged （82.1%）, 6 cases remained occluded with the same symptoms （10.7%）, and 4 cases had severer symptoms （7.1%）. Among the 46 successful cases, there were 16 cases of abdominal aorta-iliac artery （94.1%）, 16 cases of iliac-femoral artery （88.9%） and 14 cases of inferior popliteal artery, artery （66.6%）. There was no statistical difference between the abdominal aorta-iliac artery cases and iliac-femoral artery cases （P〉0.05）, but there was statistical difference between these two types and the inferior popliteal artery cases （P〈0.05）. In the successful cases, 9 cases of abdominal aorta-iliac artery （52.9%）, 10 cases of iliac-femoral artery （55.5%） and 10 cases of inferior popliteal artery （33.3%） had 5-10 cm of occlusion, with no statistical difference between the first two types （P〉0.05）, but with statistical difference between the first two types and the third type （P〈0.05）. Compared with the 14 dredged cases （71.4%）, the 7 cases （33.3%） of inferior popliteal artery cases had richer compensatory circulation （P〈0.05）. Conclusion： It＇s safe and effective to treat simple atherosclerotic occlusive disease of the lower extremity with interventional therapy. The location and length of occlusion and the abundance of compensatory circulation had effect on the therapy.展开更多

Methods： A total of 110 inpatients with ASO who performed Superficial femoral artery stent implantation were randomly divided into observation group and control group, with 55 cases in each group.Both groups received Aspirin 100 mg/d and Clopidogrel 75 mg/d. The observation group was given Furongtongmai capsule on the basis of routine treatment. After continuous treatment for 6 months, the clinical efficacy, Ankle Brachial Index （ABI）, high-sensitivity C-reactive protein （Hs-CPR） and ISR were compared between the two groups. Results： At 6 months after operation, the plasma levels of Hs-CRP in the two groups were significantly lower than those in the control group （P 〈 0.05）. The ABI of treatment group was significantly higher than the control group （P 〈 0.05）. There was a statistically significant difference in ISR incidence between the treatment group and the control group 6 months after surgery （9.09% vs 27.78%, P 〈 0.05）. Conclusion： Furongtongmai Capsule can inhibit Hs-CRP in patients with ASO after femoral artery intervention, improve the ankle brachial index and reduce the incidence of ISR.展开更多

Methods Clinical information of 9 cases suffering from lower extremity arterial occlusion and CD was investigated retrospectively. Results All the cases were less than 50 years old and the most were females (8/9). Arterial occlusions occurred in either active (5/9) or inactive (4/9) stage of CD. Besides the arteries of lower extremities, other arteries could also be involved such as aorta, iliac artery, renal artery or mesentery artery. Seven cases had atherosclerotic imaging findings (4 had aortic plaques and 6 had iliac artery stenoses). Embolectomy or thromboendarterectomy were mostly performed. Four (44.4%) cases had recurrent lower limb ischemia. Conclusions Arterial occlusive disease is a rare extraintestinal manifestation of CD. A thorough inspection of aorta is necessary. Embolectomy is mostly preferred. Anticoagulation treatment is highly recommended after the operation.展开更多

METHODS The study was a single-centre retrospective cohort study of patients with a primary TTA admitted between January 2013 and April 2015. All patients with a primary TTA were assessed for inclusion if the amputation was performed because of arteriosclerosis or diabetic complications. All patients underwent a standardized TTA procedure that was performed approximately 10 cm below the knee joint and performed with sagittalflaps. The pneumatic tourniquet, when used, was inflated around the femur to a pressure of 100 mmH g above the systolic blood pressure. The number of blood transfusions within the first four postoperative days was recorded. The intraoperative blood loss(OBL), which is defined as the volume of blood lost during surgery, was determined from the suction volume and by the weight difference of the surgical dressings. The trigger for a blood transfusion was set at a decrease in the Hgb level < 9.67 g/dL(6 mmol/L). Transfusions were performed with pooled red blood cells containing 245 m L per portion, which equals 55 g/L of haemoglobin. The TBL during the first four postoperative days was calculated based on the haemoglobin level and the estimated blood volume. The re-amputation rate was evaluated within 30 d. RESULTS Seventy-four out of 86 consecutive patients who underwent TTA within the two-year study period were included in the analysis. Of these, 38 were operated on using a tourniquet and 36 were operated on without using a tourniquet. There were no significant preoperative differences between the groups. The patients in both groups had a postoperative decrease in their Hgb level compared with preoperative baseline values. The patients operated on using a tourniquet received approximately three millilitres less blood transfusion per kilogram body weight compared with patients operated on without a tourniquet. The duration of surgery was shorter and the OBL was less for the tourniquet group than the non-tourniquet group, whereas no significant difference was observed for the TBL. The TBL median was 859 mL(IQR: 383-1315) in the non-tourniquet group vs 737 mL(IQR: 331-1218) in the tourniquet group(P = 0.754). Within the 30-d follow-up period, 9 patients in the tourniquet group and 11 in the non-tourniquet group underwent a reamputation at the trans-femoral level. The use of a tourniquet showed no statistically significant association with the 30-d re-amputation at the femur level in the multiple logistic regression model(P = 0.78). The only variable with a significant association with re-amputation was age(OR = 1.07; P = 0.02).CONCLUSION The results indicate that tourniquets do not cause severe vascular damage with an increased postoperative bleeding or failure rate as the result.展开更多
