Purpose: The lessor saphenous vein is an anatomical index in various surgical methods involving an approach to the popliteal fossa. However, occasionally, there have been some cases where the surgical process was difficult because the lessor saphenous vein was not found in the popliteal fossa during the operation process. The aim of this study is to determine the frequency of the anatomical variation of lessor saphenous vein not found in the popliteal fossa with a review of the literature. Materials and Methods: This study was conducted on 83 cases of selective neurectomy for hypertrophic calf performed in our clinic from March 1997 to June 2013. There were 42 patients, with a mean age of 32.8 years old. We confirmed the existence of the lessor saphenous vein in the popliteal fossa during the operation process. Results: Among 83 cases during this study period, the lesser saphenous vein was not found in four cases. In one patient, no lesser saphenous vein was found on either side of the popliteal fossa, and in two patients, no lesser saphenous vein was found on the left side of the popliteal fossa. As a result, the frequency of variation was found to be 4.8%. Conclusion: Due to the anatomical variation of the lessor saphenous vein, it may not be found in the midline of the popliteal fossa. Based on the literature review, several possibilities for failure to observe the lesser saphenous vein could be suggested. If surgeons are well aware of these possibilities, the steadier operation could be performed.

In the last few years there has been a resurgenceof interest in in-situ saphenous vein arterial bypass for lower extremity revascularization because of improved patency rates. we performed 1 in situ bypass oreration using the intraluminal valve-disruption tecnique. A 65-year-old female who had ztherosclerotic obstruction in the superficial and popliteal arteries underwent in situ saphenous vein arterial bypass. After harvesting of saphenous vein, we used LeMaitre retrograde valvulotome for valve-disruption technique. Completion of the arterrigraphy was performed to evaluate bothh the anastomoses. The two side brances were all ligated. In situ saphenous vein arterial bypass has become the procedure of choice for distal reconstruction in severely ischemic lower extremities because of improved long-term patency compared with reversed-saphenous vein bypass procedure.

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 purpose of this study was to compare the results of complete blood cell count (CBC) of blood samples collected from the jugular vein, cephalic vein and lateral saphenous vein and to find out if there were clinically significant differences. Total of 40 dogs were tested. CBC tests were conducted with blood samples obtained from the jugular vein, cephalic vein and lateral saphenous vein and manual differential count was performed to accurately distinguish the white blood cell (WBC) types. The results were analyzed using Repeated Measures ANOVA and posthoc test was conducted using the least significant difference method. As a result, there was a statistically significant difference (P < 0.05) in the total WBC and monocyte count. The post-hoc test of total WBC counts revealed a significant difference between the jugular vein and cephalic vein, and the jugular vein and lateral saphenous vein. For monocyte counts, a significant difference was observed between the jugular vein and lateral saphenous vein.

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.

Background: This study examined the role of superficial vein surgery in patients with combined superficial venous reflux and segmental popliteal vein reflux. Methods: We retrospectively reviewed 42 limbs in 38 patients with combined superficial venous reflux and segmental popliteal vein reflux who underwent saphenous vein ablation between January 2014 and February 2017. Patients underwent outpatient follow-up duplex ultrasonography at 3, 6, and 12 months postoperatively. Resolution of deep vein reflux was defined as reversed blood flow in a popliteal segment for less than 1.0 second and a decrease in the reflux time of more than 20% of the preoperative reflux time. Results: The mean follow-up period was 9 months (range, 3-23 months). Saphenous vein ablations were performed by stripping in 24 limbs and radiofrequency ablation in 18 limbs. Preoperative segmental popliteal vein reflux resolved in 21 of the 42 limbs (50%). Conclusion: This study demonstrated that superficial venous surgery corrected segmental popliteal vein reflux in 50% of limbs with combined superficial venous reflux and segmental popliteal vein reflux. Other prospective studies are necessary to elucidate the etiology of the non-reversible cases.

Purpose: Given that the critical nature of the microvascular anastomosis to what is often a long and difficult reconstructive operation, trainees need to have a high level of microsurgical competence before being allowed to perform microsurgery on patients. Some artificial substitutes and dead or live animal models have been used to improve manual dexterity under the operating microscope. Yet, most surgeons are not equipped with such models, so search for easy available and appropriate microsurgical practice model have been an issue. Umbilical artery, placental vessels and gastroepiploic arteries have been previously suggested as a microsurgical training model, which involves other surgical departments. The purpose of this article is to introduce that saphenous vein specimen obtained from varicose vein surgery is useful and has many advantages as training model for the practice of microvascular anastomosis. Methods: The conventional technique using perforation/inversion method with a metallic stripper is widely performed for varicose vein patients. The stripper is inserted through disconnected safeno-femoral junction and retrieved at the knee or the medial side of ankle. The length of saphenous vein specimens removed is about that of one's leg and inversed from inside out. Obtained saphenous vein specimens are re-inversed and cleansed with normal saline, to be readily available for microsurgical practice. Preserved in a squeezed wet saline gauze and refrigerated, frozen or glycerated specimens were investigated into their comparative quality for microsurgical practice. Results: Varicose vein surgery remains one of the common operations performed in the field of plastic surgery. Convenient informed consent regarding the vessel donation can be easily signed. The diameter of the obtained saphenous vein is as variable as 1.5 to 6 mm, which is already stripped, and is in sufficient length corresponding to that of patient's leg. Vessels specimens were available for microsurgical practice within 1 week period when preserved with squeezed wet saline gauze, and the preservation period could be extended monthly by freezing it. Conclusion: Saphenous vein obtained from varicose vein patients provide with variable size of vessel lumen with sufficient length. The practice can be cost effective and does not require microsurgical laboratory. Additionally there is no need of involving other surgical departments in acquiring vessel specimens. Furthermore, simple preservation method of refrigerating for a week or freezing with squeezed wet saline gauze for a month period, allow the saphenous vein obtained after varicose vein surgery as an excellent model for the microsurgical practice.

Background: The aim of this study was to evaluate the midterm clinical outcomes after modified high ligation and segmental stripping of small saphenous vein (SSV) varicosities. Methods: Between January 2010 and March 2013, 62 patients (69 legs) with isolated primary small saphenous varicose veins were enrolled in this study. The outcomes measured were reflux in the remaining distal SSV, the recurrence of varicose veins, the improvement of preoperative symptoms, and the rate of postoperative complications. Results: No major complications occurred. No instances of the recurrence of varicose veins at previous stripping sites were noted. Three legs (4.3%) showed reflux in the remaining distal small saphenous veins. The preoperative symptoms were found to have improved in 96.4% of the cases. Conclusion: In the absence of flush ligation of the saphenopopliteal junction, modified high ligation and segmental stripping of small saphenous vein varicosities with preoperative duplex marking is an effective treatment method for reducing postoperative complications and the recurrence of SSV incompetence.

Background: The purpose of this study is to evaluate the validity of a combined high saphenous vein division and sclerotherapy without sacrificing saphenous vein for varicose vein. Material and Method: Between August 2004 and October 2005, 70 limbs in 50 patients were treated by a combined high saphenous vein division and sclero-therapy. The operative indication is valvular incompetence of femoral-saphenous or popliteal-saphenous junction. Patients received local anesthesia and were treated by a combined high saphenous vein division, ligation of incompetent perforating vein and $1{\sim}3%$ sclerosant. Patients received 1 day hospitalization and applied in com-pression stocking for 6 weeks. Patients followed after 1 week, 1 and 3 months. Result: Mean age of patients was $50{\pm}11$. The female was more common. 8 patients was no symptom, another 42 patients complained of pain, heaviness and fatigue of limbs. The symptoms of varicose vein disappeared 1 month after the procedure in all symptomatic patients. 8 patients needed a adjuvant sclerotherapy for residual varicose vein on 1 week after the procedure. There were only minor complications such as hematoma (1), wound infection (1), thrombophlebitis (20), skin blister (10), hyper-pigmentation (1), and skin ulcer (1). Conclusion: We concluded that a combined high saphenous vein division and sclerotherapy without sacrificing saphenous vein for varicose vein is simple, less invasive, economical, and effective treatment for primary varicose vein, and it has a special advantage that saphenous vein can be used as a bypass conduit later. The method was selective in old aged patients.

Background: The safety and efficacy of arterial composite grafts for total arterial revascularization have been demonstrated. The saphenous vein (SV) is a widely used graft because of its accessibility, sufficient length, and ease of manipulation. Our aim was to compare mid-term outcomes of saphenous vein Y-grafts with radial artery Y-grafts joined by anastomosis to the left internal thoracic artery. Materials and Methods: Records of off-pump coronary artery bypass grafting with composite Y-grafts based on the left internal thoracic artery technique in 552 patients were analyzed retrospectively. After propensity score matching, 79 radial arterial (RA) composite grafts (RA group) and 79 saphenous vein composite grafts (SV group) were compared. The duration of mean follow-up was $24.6{\pm}14.6$ months (range, 1 to 55 months). Results: There were no differences in surgical mortality, all-cause mortality, or morbidity among the groups. Rates of 4-year survival were 91.7% and 96.3% in the RA and SV groups, respectively (p=0.519). The coronary reintervention-free survival rate and freedom from major adverse cardiovascular or cerebrovascular events were similar in the two groups (p=0.685, p=0.564). Conclusion: Construction of composite Y-grafts using the radial artery or saphenous vein showed similar mid-term results. Long-term follow-up and randomized trials will be needed to confirm our present conclusions.
