Microvascular reconstruction, in the oral and maxillofacial regions, is a widely accepted as the best way to overcome the complex oral cavity defects. Many patients requiring composite reconstructions have been treated previously with radiation therapy, chemotherapy, selective and/or functional neck dissection or any of these combinations. In many cases of these patients, inadequate neck vessels for the microanastomosis of free flap are available, due to a lack of recipient vessels in the neck, poor vessel quality or vessel caliber mismatch. To achieve a tension-free anastomosis, vein grafting must be considered to span the vessel gap between the free flap pedicle and the recipient neck vessels. Although most microsurgeons believed that interpositional grafts are to be avoided due to vessel thrombosis and increased number of necessary microanastomosis, we, authors have some confidence of equivalency between reconstruction with and without interpositional saphenous vein graft. The great saphenous vein, also known as the long saphenous vein, is the large subcutaneous superficial vein of the leg and thigh. It joins with the femoral vein in the region of femoral triangle at the saphenofemoral junction, and coursed medially to lie on the anterior surface of the thigh before entering an opening in the fascia lata, called the saphenous opening. For a better understanding of the great saphenous vein graft for the interpositional vessel graft in the oral cavity reconstructions, and an avoidance of any uneventful complications during these procedures, the related surgical anatomies with their harvesting tips are summarized in this review article in the Korean language.

The Saphenous vein is still the graft of choice for bypass of small calibered peripheral arteries, and many recent studies revealed that the "In Situ" technique had higher rate of long term patency than the conventional "reversed" one. A 71-year-old male who had atherosclerotic obstruction in the superficial femoral and popliteal trifurcation underwent In Situ saphenous vein arterial bypass. The saphenous vein is exposed by a long medial skin incision over the course of the vein. All branches of vein are ligated. A olive-tipped metal needle is introduced into the vein from above and everts the valves. The patient has been followed for 2 months after operation. The graft remained pulsatile and the gangrenous areas on the toe proceeded to heal. We think In situ vein bypass offers an excellent and safe method of revascularization of the arterial occlusion below the knee although it is technically demanding and the time consuming. time consuming.

Objectives: To completely excise a malignant tumor which invades carotid artery walls, the resection and reconstruction of the carotid artery is essentially required. In most of the cases, interposition graft using a saphenous vein has been performed, however the vessel caliber discrepancy between a common carotid artery and the saphenous vein can result in a problem on surgical technique. We have introduced and evaluated a new titanium hemoclip tailing method to overcome vessel caliber discrepancy in interposition saphenous vein graft for carotid artery resection in the treatment of head and neck cancers. Method: After carotid artery resection, the calibers of the proximal common carotid artery and the vein were compared, and an orifice of the common carotid artery was gradually reduced to a little larger than or the same size as the orifice of the vein by using the titanium hemostatic clip. Subsequently, the common carotid artery was connected to the vein through anastomosis. The same method was also applied to the distal anastomosis site. There after, the vessels were connected through the anastomosis, and a circulation was restored by releasing a vascular clamp. Then, a titanium hemostatic clip-applied redundant portion on the outside of carotid artery was sutured by the blanket edge suture method, using 6-0 Prolene. Results: We have experienced this method in two patients with recurrent squamous cell carcinoma and neuroblostoma, respectively. The interposition saphenous vein graft of these patients was found to maintain good patency on the follow up angiography after one year, and they had no specific vascular complication, such as atherosclerosis. Conclusion: This method made it possible to simply perform the interposition saphenous vein graft (ISVG) within a short time and, therefore, was very useful for shortening the duration to block circulation.

A 40-year-old male developed the swelling of the right leg one month after trauma on cycling. Conservative measures to relieve the swelling of the right leg for three months were failed. Venogram showed complete obstruction of the right common iliac vein. Crossover bypass [Palmas operation] with great saphenous vein graft for relief of venous stasis of the right leg was performed. Postoperatively, the swelling of the right leg was subsided and able to walk without edema of the right leg.

Between July, 1987, and September, 1988, 6 patients with coronary occlusive disease received coronary artery bypass surgery at Kyungpook University Hospital. There were five males and one female whose age ranged from 39 to 64 years[mean 54*8.0 years]. Of the 6 patients, 5 suffered from unstable angina, 1 suffered from stable angina. Selective coronary angiography revealed a significant stenosis of the left anterior descending artery in 6 cases, of its diagonal branch in 1 case, of the right coronary artery in 1 case, the circumflex artery in 1 case, and of its obtuse marginal branch in 1 case. The mode of anastomosis were single saphenous vein graft in 3 cases, single left internal mammary artery graft in 1 case, double saphenous vein graft with sequential anastomosis in 1 case, and left internal mammary artery plus saphenous vein graft in 1 case. Of these, 6 grafts to left anterior descending artery were done. There was no operative death, but perioperative myocardial infarction was happened in 1 case. All survivors were free of angina and discontinuing medical therapy during the follow up period[mean 7.8*5.15 months].

Background: The long term patency of the free saphenous vein graft, which is the most commonly used conduit, anastomosed to the ascending aorta has been reported to be lower than that of arterial grafts. We evaluated early clinical outcome and the angiographic patency of the saphenous vein composite graft based on the left internal thoracic artery, and compared these results with those of using arterial composite grafts. Material and Method: From September 2006 to October 2008, 419 patients underwent off-pump coronary revascularization. Among those, 295 patients (70.4%) were revascularized using composite grafts (group I: saphenous vein composite graft, n=71, group II: arterial composite graft, n=224). The clinical results were compared between the 2 groups. Early postoperative coronary angiograms were performed in all the patients. ($1.6{\pm}1.6$ days) Result: The number of the distal anastomosis per patient was $3.5{\pm}1.0$ and $3.1{\pm}0.8$ in group I and II, respectively (p=.002). The operative mortality (n=2, 0.7%) and postoperative complications such as atrial fibrillation (n=73, 24.7%), perioperative myocardial infarct (n=6, 2.0%), acute renal failure (n=6, 2.0%), reoperation for bleeding (n=5, 1.7%), cerebrovascular accident (n=3, 1.0%), and mediastinitis (n=1, 0.3%) were not related with the use of saphenous vein graft. Early coronary angiograms revealed a 96.9% (126/130) for the saphenous vein grafts and a 98.8% (479/485) for the composite graft in group II (p=.231). Conclusion: Our data suggested that a saphenous vein graft might be used as analtemative conduit to the arterial graft for constructing a composite graft, as based on our early clinical and angiographic results. Further study is required to establish the long-term efficacy of using a saphenous vein as a composite graft.

Background: When internal thoracic artery (ITA) and saphenous vein graft are anastomosed to the same coronary artery, the patency rate of the internal thoracic artery graft with relatively narrow diameter may be decreased owing to competition of pressure and flow rate. We evaluate the clinical outcome and the patency of the ITA graft in patients undergoing dual grafting to the same coronary artery. Material and Method: In 14 patients with the ITA graft having relatively low flow, the ITA and saphenous vein graft were anastomosed to the same coronary artery. During the mean follow-up period of 33.5 months, coronary angiography was performed in 6 patients who complained of recurrent angina, needed confirmation of graft flow, or showed postoperative Q wave. Result: In all 6 patients, the ITA and saphenous vein grafts were patent without stenosis or obstruction. Two patients showed good flow in both grafts, 2 showed competitive flow in the ITA graft, and the remaining 2 showed poor flow in the ITA graft. Conclusion: Early operative closure When saphenous vein grafting was added to the same coronary artery that the internal thoracic artery was anastomosed to, the perfusion to the coronary artery was satisfied and the dual grafting did not affect the short-term and mid-term patency rate of the ITA.

Background: Distal anastomosis using artificial vascular graft is difficult when luminal size mismatch occurred owing to severe occlusion of popliteal artery and its branches. So we reconstructed blood flow to ischemic lower limb by using autologous greater saphenous vein in situ graft (GSVISG) as vascular graft material. Material and Method: From July 2000 to July 2005, 26 patients treated using GSVISG. We analyzed clinical results retrospectively by chart review. Result: There was no in hospital or early postoperative death and 6 late deaths occurred during follow up period. Postoperative complications were 5 cases of early graft obstruction, 2 cases of wound dehiscence, 1 case of graft aneurysmal change, 1 case of seroma formation at inguinal wound and 1 case of graft injury during valvulotomy. Overall patency rate during follow up period was 69.3%. Conclusion: Greater saphenous vein in situ graft is acceptable vascular graft for arterial occlusive disease of lower extremity.

Management of postoperative tarsal tunnel syndrome is a perplexing problem to the surgeons. Autogenous vein wrapping graft is a effective method to decompress the tarsal tunnel. We treated 2 cases of postoperative tarsal tunnel syndrome with autogenous saphenous vein wrapping graft technique, and could get good results. Autogenous vein wrapping graft seems to be a good technique for tarsal tunnel syndrome with severe adhesion, particularly after surgery, and postoperative nerve adhesion can be prevented.
