Abstract： Objective To investigate the extracellular matrix （ECM） gene expression profile of saphenous vein （SV） in end-stage renal disease （ESRD） patients undergoing coronary artery bypass grafting （CABG）. Methods Sixty-eight patients who were diagnosed as coronary artery disease by coronary angiography and admitted to Department of Cardiovascular Surgery，Zhongshan Hospital of Fudan University from July 2004 to December 2010 were enrolled in this study. According to whether or not they had preoperative ESRD history，all the 68 patients were divided into 2 groups，the ESRD group with 30 ESRD patients who needed maintenance hemodialysis，and the control group with 38 patients without preoperative renal disease. Preoperative clinical data of all the patients were collected in detail. SV samples were obtained at the time of CABG. Microarray，immunohistochemistry and Western blotting were used to investigate the expression profile of ECM genes of SV in ESRD patients undergoing CABG. Results There was no statistical difference in preoperative clinical variables between the 2 groups except the variables which were directly related to their kidney disease （P＞0.05）. There were 16 genes that were up-regulated at least 3-fold and 3 genes that were down-regulated at least 3-fold in the ECM gene expression profile of SV in the ESRD group patients before CABG. The expressions of matrix metalloproteinases-2 （MMP-2） and matrix metalloproteinases-9 （MMP-9） of the ESRD group were significantly higher than those of the control group （2.60±0.50 vs. 0.70±0.16，1.80±0.40 vs. 0.60±0.15，P＜0.01）. The expressions of tissue inhibitor of metalloproteinase-2 （TIMP-2） and tissue inhibitor of metalloproteinase-3 （TIMP-3） of the ESRD group were significantly lower than those of the control group （0.60±0.19 vs. 2.20±0.30，0.90±0.28 vs. 2.40±0.70，P＜ 0.05）. Conclusion A variety of ESRD-related risk factors of cardiovascular diseases may severely influence on the balance of ECM gene expression of SV before CABG，and the resulting imbalance is a risk factor to aggravate SV graft disease after CABG.
External support stent is a potential means for restricting the deformation and reducing wall stress of the vein graft, thereby improving the long-term patency of the graft in coronary artery bypass surgery. However, there still lacks a theoretical reference for choosing the size of stent based on the diameter of graft. Taking the VEST (venous external support) stent currently used in the clinical practice as the object of study, we constructed three models of VEST stents with different diameters and coupled them respectively to a model of the great saphenous vein graft, and numerically simulated the expansion-contraction process of the vein graft under the constraint of the stents to quantitatively evaluate the influence of stent size on the radial deformation and wall stress of the vein graft. The results showed that while the stent with a small diameter had a high restrictive effect in comparison with larger stents, it led to more severe concentration of wall stress and sharper changes in radial deformation along the axis of the graft, which may have adverse influence on the graft. In order to solve the aforementioned problems, we ameliorated the design of the stent by means of changing the cross-sectional shape of the thick and thin alloy wires from circle into rectangle and square, respectively, while keeping the cross-sectional areas of alloy wires and stent topology unchanged. Further numerical simulations demonstrated that the ameliorated stent evidently reduced the degrees of wall stress concentration and abrupt changes in radial deformation, which may help improve the biomechanical environment of the graft while maintaining the restrictive role of the stent.
ObjectiveTo observe the efficiency of endovenous laser therapy combined with planning sucking operation in the treatment of great saphenous varicose veins. MethodsTotally 48 patients (60 limbs) were treated from May 2011 to May 2014 in general surgery department of our hospital. The main trunk of great saphenous vein was ablated by endovenous laser treatment; and the varicose veins in calf were resected by planning sucking operation. ResultsAll 48 patients (60 limbs) were cured without recurrent during 6-36 months followed-up. The operative time of each side was 18-43 min, the average operative time was 22.6 min; with 1-3 skin incisions. Hospital stay was 5-8 d, the average hospitalization time was 6.7 d. After operation, the varicose veins and the felling of swelling were disappeared, the pigmentation was reduced or disappeared. Local skin numbness showed in 6 cases and recovered in 3-7 months after operation. Felling of burns appeared in 2 cases, and was healed after treatment. Ankle swelling presented in 5 cases, and released in 6-13 d with related treatment. Different degree of subcutaneous bruising appeared without any hematoma, and recovered in 2-4 weeks. Two cases were lost during the followed-up. ConclusionsEndovenous laser therapy combined with planning sucking operation is safe and effective in the treatment of great saphenous varicose. It is worthy of promotion with minimum damage, less pain, fast recovery, no scars, shorter operative time, and shorter hospital stay.
Objective To provide the anatomic basis for defect repair of the knee, leg, foot and ankle with great saphenous venosaphenous neurocutaneous vascular island flaps. Methods The origin, diameter, branches, distribution and anatomoses of the saphenous artery and saphenous neurocutaneous vascular were observed on 20 sides of adult leg specimens and 4 fresh cadaver voluntary legs. Another4 fresh cadaver voluntary legs were radiogeaphed with a soft X-ray system afterthe intravenous injection of Vermilion and cross-sections under profound fascial, otherhand, micro-anatomic examination was also performed in these 4 fresh cadaver legs. The soft tissue defects in lower extremity,upper extremity, heel or Hucou in handwere repaired with the proximal or distal pedicle flaps or free flaps in 18 patients(12 males and 6 females,aging from 7 to 3 years). The defect was caused by trauma, tumour, ulcer and scar.The locations were Hucou (1 case), upper leg(3 cases), lower extremity and heal (14 cases). Of then, 7 cases were complicatedby bone exposure, 3 cases by tendon exposure and 1 case by steel expouse. the defect size were 4 cm×4 cm to 7 cm×13 cm. The flap sizes were 4 cm×6 cm to 8 cm×15 cm, which pedicle length was 8-11 cm with 2.-4.0 cm fascia and 12 cm skin at width. Results Genus descending genicular artery began from 9.33±0.81 cm away from upper the condylus medialis, it branched saphenous artery accompanying saphenous nerve descendent. And saphenous artery reached the surface of the skin 7.21±0.82 cm away from lower the condylus medialis,and anastomosed with the branches of tibialis posterior artery, like “Y” or “T” pattern. The chain linking system of arteries were found accompanying along the great saphenous vein as saphenous nerve, and then a axis blood vessel was formed. The small artery of only 00-0.10 mm in diameter, distributed around the great saphenousvein within 58 mm and arranged parallelly along the vein like water wave in soft X-ray film. All proximal flaps,distal pedicle flaps and free flaps survived well. The appearance, sensation and function were satisfactory in 14 patientsafter a follow-up of 6-12 months. Conclusion The great saphenous vein as well as saphenous neurocutaneous has a chain linking system vascular net. A flap with the vascular net can be transplanted by free, by reversed pedicle, or by direct pedicle to repair the wound of upper leg and foot. A superficial vein-superficial neurocutaneous vascular flap with abundance blood supply and without sacrificing a main artery is a favouriate method in repair of soft tissue defects in foot and lower extremity.
Objective To investigate the clinical feasibility of different types of the saphenous neuro-veno-fascial cutaneous flaps. Methods From June 1996 to October 2002, 18 cases of skin defects in the knee and the lower part of the limb were treated with proximally(4 cases) or distally(11 cases) based pedicles of saphenous neuro-venofascial cutaneous flap or crossleg flap (3 cases)according to the site of defects . The sizes of the flaps ranged from 4 cm×5 cm to 9 cm×20 cm. Results The flaps survived completely in 17 cases, distal 1/5 of the flap necrosed partially in 1 case because of vein drainage disturbance. The colour and texture of flaps were excellent, the appearance and function were satisfactory after a follow up of 6-24 months.Conclusion The saphenous neuro-veno-fascial cutaneous flap is an idea flap in repairing skin defects of the knee, the leg, the ankle and the foot because it is easy to be designed and dissected and it has reliable blood supply and preserved main artery. The relationship between the septal perforating branches of the tibial posteriorartery and survival size of flap need to be investigated further.
