Objective To summarize the treatment outcomes of antegrade sequential anastomosis of great saphenous veins in off-pump coronary artery bypass grafting for coronary atherosclerotic heart disease. Methods A total of 116 patients with coronary atherosclerotic heart diseases underwent off-pump coronary artery bypass grafting from January 2013 to June 2015 in our hospital. There were 63 males and 53 females with a mean age of 42–80 (64.26±9.67) years. Left internal mammary artery was anastomosed to left anterior descending artery. The rest of the target vessels received antegrade sequential anastomosis of great saphenous veins with the order of proximal ascending aorta, diagonal branch, circumflex branch, obtuse marginal branch, left ventricular branch and posterior descending artery. Results All patients were performed off-pump coronary artery bypass grafting successfully without death or perioperative myocardial infarction. A total of 436 grafts were adopted with 3.75±0.53 in each patient. Three patients suffered low cardiac output syndrome, and were cured after administration of vasoactive drugs combined with the intra-aortic balloon pump. One patient suffered tardive pericardial tamponade and one acute renal failure, who were cured with disappearance of angina symptoms and increase of activities without discomfort. Conclusion Antegrade sequential anastomosis, as a safe and effective method, can reduce aortic stoma, save the length of grafts, shorten operative time and quickly restorate blood supply of myocardium in off-pump coronary artery bypass grafting.

Objective To explore perioperative outcomes of coronary artery bypass grafting （CABG） using the radialartery as the second arterial graft. Methods Clinical data of 175 consecutive patients undergoing off-pump coronary artery bypass grafting （OPCAB） in General Hospital of Shenyang Military Command from August 2011 to April 2012 were retrospectively analyzed. All the 175 patients were divided into two groups. There were 75 patients including 49 male and 26 female patients with their age of 56.8±8.2 years in group 1，who received radial artery as a graft vessel. There were 100patients including 66 male and 34 female patients with their age of 57.7±8.1 years in group 2，who received great saphenousvein but not radial artery as the graft vessel. The use of left internal mammary artery as a graft vessel was 100% in both groups. Perioperative cardiovascular events and other clinical results were compared between the two groups. Results All the patients survived OPCAB and there was no 30-day death. There was no statistical difference in operation time，thoracic drainage within the first 24 hours after surgery or postoperative hospital stay between the two groups（P＞0.05）. Length of postoperative ICU stay and mechanical ventilation time of group 1 were shorter than those of group 2，although the differencewas not statistically significant. The percentage of patients receiving prolonged postoperative inotropic therapy of group 2 was higher than that of group 1 ［16% （16/100） vs. 12% （9/75）］，although the difference was not statistically significant. Postoperatively，there was no patient in group 1 who had new-onset myocardial ischemia or received intra-aortic balloon pump （IABP） support for hemodynamic instability. In group 2，3 patients had new-onset myocardial ischemia and 2 patientsreceived IABP support after OPCAB. Conclusion Radial artery can partly replace great saphenous vein as a graft vesselfor OPCAB，which does not increase the risk of perioperative cardiovascular events but is beneficial for postoperativerecovery to some degree. Radial artery can be more extensively used in CABG.
The choice of the graft conduit for coronary artery bypass grafting (CABG) has significant implications both in the short-and long-term. The patency of a coronary conduit is closely associated with an uneventful postoperative course, better long-term patient survival and superior freedom from re-intervention. The internal mammary artery is regarded as the primary conduit for CABG patients, given its association with long-term patency and survival. However, long saphenous vein (LSV) continues to be utilized universally as patients presenting for CABG often have multiple coronary territories requiring revascularization. Traditionally, the LSV has been harvested by creating incisions from the ankle up to the groin termed open vein harvesting (OVH). However, such harvesting methods are associated with incisional pain and leg wound infections. In addition, patients find such large incisions to be cosmetically unappealing. These concerns regarding wound morbidity and patient satisfaction led to the emergence of endoscopic vein harvesting (EVH). Published experience comparing OVH with EVH suggests decreased wound related complications, improved patient satisfaction, shorter hospital stay, and reduced postoperative pain at the harvest site following EVH. Despite these reported advantages concerns regarding risk of injury at the time of harvest with its potential detrimental effect on vein graft patency and clinical outcomes have prevented universal adoption of EVH. This review article provides a detailed insight into the technical aspects, outcomes, concerns, and controversies associated with EVH.

Objective To compare scar and incision satisfaction between Prolene polypropylene suture and conventional silk suture for dermal suture in high ligation and stripping of primary great saphenous varicose vein. Methods A total of 83 patients who met the inclusion criteria were admitted in the West China Hospital, including 27 males and 56 females. The average age was 46.7 years old, ranging from 30 to 63 years old. Forty-two patients were grade C2 and 41 were grade C3 according to the CEAP grading. Patients were divided into a polypropylene suture group (even number,n=45) and a silk suture group (odd number,n=38) according to admission date order. Prolene 5-0 polypropylene suture was used for dermal suture in the patients of the polypropylene suture group and 1# silk suture in the patients of the silk suture group. The pigments of incision area and suture area and their widths, and the points of Patient and Observer Scar Assessment Scale score (POSAS) and patient and observer satisfaction score of incision were observed on month 6 for following-up. Results ① The gender, age, body mass index, and proportion of C2 of the CEAP grading or smoking had no significant difference between these two groups (P>0.05). ② All the operations were successful and all the patients were followed up. All the incisions healed well and had no infection. There was a few subcutaneous hematoma in one incisionof the 2 patients on day 3 after operation in the two groups, which markedly improved after dressing treatment. The sutures of all the patients were removed on day 14 after operation. ③ The pigment of incision area and its width, and the points of POSAS had no significant differences between the two groups (P>0.05). The pigment of suture area and its width, and the points of patient and observer satisfaction score of the incision in the polypropylene suture group were significantly better than those in the silk suture group (P<0.05). Conclusion Prolene polypropylene suture is preference to conventional silk suture in aesthetic results and patient satisfaction for dermal suture of great saphenous varicose vein surgery.
Objective To compare the patency of the postoperative vessel bridge grafts between the no-touch technique and the conventional technique for saphenous vein harvest in the coronary artery bypass grafting. Methods A total of 70 patients underwent coronary artery bypass grafting from January 2014 to January 2015 in the First Affiliated Hospital of Zhengzhou University. They were randomly divided into a conventional technique group (saphenous vein obtained by traditional technique) and a no-touch technique group (saphenous vein obtained by no-touch technique). There were 34 patients in the conventional technique group, including 16 males and 18 females with an average age of 61.6±6.4 years. There were 36 patients in the no-touch technique group, including 16 males and 20 females with an average age of 62.2±6.6 years. The 1-year postoperative coronary CT angiography (CTA) results were compared. Results Seventy patients underwent coronary CTA examination 1 year postoperatively. The patency rate of the conventional technique group and no-touch technique group were 83/116 (71.6%) and 113/122 (92.6%). Logistic regression analysis showed a statistical difference between the non-touch technique and the conventional technique (P<0.05). Conclusion The short-term patency rate of vessel bridge grafts is higher when the no-touch technique is used.
OBJECTIVE: Retrospective clinical analysis of primary surgical operation in the treatment of lower limb accompanied by chronic leg ulcer were adopted in this study. METHODS: From September 1990 to June 1998, there were 31 males and 20 females, aged 68 years in average, the area of ulcer varied from 5 cm x 3 cm to 22 cm x 11 cm. The ligation and strip of saphenous vein, debridement and free skin flap grafting were finished in primary operation. RESULTS: The skin flaps were survived completely in 50 cases, only 1 case was necrosis partially and healed after changing dressing. Forty-two cases were followed up for 16 months to 9 years (66 months in average), the varicosis and ulcer were healed in 39 cases and only 3 relapsed in ulceration. CONCLUSION: Primary surgical operation in the treatment of varicosis of lower limb accompanied by chronic ulcer is practicable in clinic. The curative efficacy is satisfactory and the operative manipulation is simple.
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.
ObjectiveTo explore the mid-term outcomes achieved by using the left internal mammary artery to saphenous vein composite grafts in off-pump coronary artery bypass surgery (OPCAB) for elderly patients. MethodsA total of 59 elderly patients (≥70 years old) underwent OPCAB by using left internal mammary artery (LIMA) to radial artery (RA) or saphenous vein (SV) composite grafts in Xinhua Hospital between March 2006 and October 2012. There was 37 males and 22 females at age of 72.71±1.95 years. Twenty one patients used LIMA-SV composite grafts (LIMA-SV group), and 38 patients used LIMA-RA composite grafts (LIMA-RA group). ResultsAll patients successfully underwent OPCAB with LIMA-SV or LIMA-RA composite grafts. There was one early death in the LIMA-RA group. No statistical differences in early postoperative outcomes were found between the two groups (P > 0.05). During a follow-up of 12 to 91 months, no patient occurred revascularization. There were no statistical differences in overall survival or graft patency rate, and 1 year, 3 years or 5 years survival rates between the two groups (P > 0.05). The patency rate of LIMA in each group was 100% respectively. There was also no statistical difference in overall patency rate of SV and RA between the two groups at the end of 1 year, 3 years or 5 years (P > 0.05). ConclusionAlthough artery grafts are the best choice for OPCAB, LIMA-SV composite grafts can be used as an alternative graft for elderly patients whose RA or right internal mammary artery is not possible or advisable.
