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.
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: 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.
ObjectiveTo explore the outcomes achieved by using left internal mammary artery (LIMA) to radial artery (RA) or saphenous vein (SV) Y-composite grafts in minimally invasive direct coronary artery bypass grafting (MIDCAB) for patients with multiple vessel disease. MethodsFrom January 2009 through May 2015, 56 patients (36 males and 20 females) with multiple vessel disease underwent MIDCAB with LIMA-RA or LIMA-SV Y-composite grafts without cardiopulmonary bypass in our hospital. MIDCAB was performed through a left anterior minithoracotomy. Thirty four patients used LIMA-RA grafts, and twenty two patients used LIMA-SV grafts. ResultsAll patients success-fully underwent MIDCAB with LIMA-SV or LIMA-RA Y-composite grafts. No patient required to convert to sternotomy during the surgery. Revascularization was performed for 2 target vessels in 12 patients, 3 target vessels in 41 patients and 4 target vessels in 3 patients. Mean postoperative ventilation time was 27.14±31.35 h. Mean ICU time was 3.16±2.53 d, and mean postoperative inhosptial time was 11.89±3.91 d. Thirty-day mortality was 1.79% (1/56). At a follow-up of 1 to 77 months, no patients received revascularization. The overall survival at 2 years postoperatively was 94.4%±5.4% in the LIMA-RA group and 86.8%±9.2% in the LIMA-SV group (P=0.299). The patency rate of LIMA was 100.0%. The overall patency rate of RA or SV grafts at 2 years postoperatively was 90.3%±5.3% or 86.7%±6.3% with no statistical difference (P=0.265). ConclusionMIDCAB with LIMA-RA or LIMA-SV Y-composite grafts is a safe and an effective procedure with favorable early and mid-term outcomes for patients with multiple vessel disease. LIMA-SV composite graft can be used as an alternative graft for patient whose RA is not possible or advisable.
ObjectiveTo summarize the experience of 4 patients with a great saphenous venous graft patency after 15 years of postoperitive great saphenous venous sequential aortic coronary artery bypass grafting. MethodWe retrospectively analyzed the clinical data of 4 patients accepted great saphenous vein aortic coronary artery bypass graft under moderate hypothermia cardiopulmonary bypass from November 1989 to December 1992 year. There were 3 males and 1 female with a mean age of 48.3 years ranging from 40-58 years. We harvested great saphenous vein under groin 45-50 cm. The proximal and distal anastomoses were performed with parachute technique under two clamps technique. Coronary artery bypass graft was performed by two sequential grafts routinely. Aspirin was given through nasal tube 6 hours after operation. The risk factors of arteriosclerosis were controlled by patients themselves after discharge. ResultFour patients received coronary angiography in 15, 16, 18, and 21 years after surgery and the grafts and both proximal and distal anastomoses were patent. The patients lived about 20 years without angina. Conclusioncarefully dealing with the vein graft, taking sequential bypass grafting to guarantee parabolic curve and meticulous anastomosis are preconditional and necessary for long-term patency.
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.
