Background: We observed several cases of rare vascular anomalies within the femoral triangle during varicose vein operations. Methods: From among 2,093 patients who underwent stripping operations of the great saphenous vein between January 2002 and June 2016, 14 cases of rare vascular anomalies were enrolled in this study. Results: Twelve cases of femoral artery and vein transposition (0.57%), 1 case of separate entrance of the great saphenous vein trunk and its tributaries (0.05%), and 1 case of separate entrance with femoral artery and vein transposition (0.05%) were observed. The preoperative diagnosis rate was 71% (10 of 14) using duplex ultrasound. In all cases of femoral artery and vein transposition, the saphenofemoral junction was located at the lateral or posterolateral side of the superficial femoral artery, corresponding to complete or incomplete transposition, respectively. Among the 12 cases of femoral artery and vein transposition, 5 cases were complete transposition and 7 cases were incomplete transposition. In 2 cases of separate entrance of the great saphenous vein trunk and its tributaries, the separated tributaries formed a common trunk before connecting to the femoral vein. Conclusion: The anatomy of the saphenofemoral junction may infrequently be altered in some individuals. Detailed preoperative sonographic examinations and meticulous groin dissection during the operation are necessary to prepare for unexpected anatomical variations.

A twenty six year old man was admitted to our clinic for bleeding from a venous ulcer of the left leg. His left femoral vein had been ligated for bleeding control after a traffic accident that happened when he was 5 years old. He had a varicose vein, stasis dermatitis, and a venous ulcer on his left leg. To shunt left femoral venous return to the right femoral vein, we did a crossover bypass with arteriovenous fistula using the right greater saphenous vein. To get good patency of the arteriovenous fistula, the bypass graft was closed 6 weeks after the initial operation. He maintained his left leg circumference relatively well for 6 months after the operation. We report the case of a patient who had a vein crossover bypass for a chronic femoral vein ligation.

Hematoma is quite a common complication of femoral arterial catheterization. However, to the best of our knowledge, there have been no previous studies regarding deep vein thrombosis (DVT) caused by compression of a vein due to a hematoma. We report a case of a hematoma developing after femoral arterial catheterization and causing extensive symptomatic DVT. A 59-year-old male was seen in our Emergency Department with right lower leg swelling 15 days after coronary stent implantation performed using right femoral artery access. Computed tomographic (CT) scanning revealed a large hematoma (45 mm in its longest diameter) compressing the common femoral vein and with DVT from the right external iliac vein to the popliteal vein. Due to the extensive DVT involvement, we decided to release the compressed common femoral vein by surgical evacuation of the large hematoma. However, even following evacuation of the hematoma, as the DVT did not resolve soon, further mechanical thrombectomy and catheter-directed thrombolysis were performed. Angiography then showed nearly resolved DVT, and the leg swelling was improved. The patient was discharged with the anticoagulation medication, warfarin.

A 27-year-old female patient was referred due to an edematous left lower extremity. Both saphenous veins had been ablated with an endovenous laser procedure used to treat varicose veins. Venography revealed that the left common femoral vein had been divided and that thrombosis was present at the site of division. No veins were available around the thighs. The patient was treated using a staged procedure. During the first stage, a ringed polytetrafluoroethylene graft was used to repair the common femoral vein, and an arteriovenous fistula was constructed from the femoral artery to the graft using a short segment of cephalic vein to increase graft patency. The edema was relieved postoperatively and the graft was patent. During the second stage, which was performed 6 months later, the fistula was occluded by coil embolization. The staged procedure described herein provides an alternative for venous reconstruction when autologous vein is unavailable.

The Incidence of synovial sarcoma Is very low but sarcoma Is a well-defined entity, which occurs primarily around large Joints and usually in association with tendon sheaths, bursae or the capsule. Recently we experienced a case of synovial sarcoma which invaded the right femoral vein of 433 5-year-old man. The tumor was widely excised incl ding the invaded femoral vein, and vein reconstruction was done using saphenous vein graft. The postoperative course was uneventful without intractable edema nor disability.

Ventriculoperitoneal (VP) shunt is commonly and effectively used to treat hydrocephalus. Intracardiac migration of the shunt catheter is a rare complication. A 68-year-old woman underwent ventriculoperitoneal shunting for hydrocephalus secondary to subarachnoid hemorrhage due to anterior communicating artery aneurysm rupture. Two weeks after the shunt surgery, she had suffered from the abdominal pain. Plain chest x-rays, computed tomography, and echocardiography revealed the distal catheter which was in the right ventricle of the heart. We tried to remove the catheter through the internal jugular vein by fluoroscopic guidance. But, the distal catheter was kinked and knotted; therefore, we failed to withdraw the catheter. After then, we punctured the right femoral vein and pulled down the multi-knotted shunt catheter to the femoral vein using the snare catheter. Finally, we removed the knotted distal catheter via the femoral vein and a new distal catheter was placed into the peritoneal cavity. We report a case in which the distal catheter of the VP shunt migrated into the heart via the internal jugular vein. We emphasize the importance of careful and proper placement of the distal catheter during the tunneling procedure to prevent life-threatening complications.

A 69-year-old man was admitted to our hospital for deep vein thrombosis, and he had experienced two episodes of left leg swelling: one happened after an 11 hour-air trip from Europe in June 2007, and the other developed 3 days after an operation for a herniated lumbar disc in July 2007. We treated him for a deep vein thrombosis of the deep femoral vein after admission. However, we arrived at the final diagnosis of angioleiomyosarcoma after the operation for the tentative diagnosis of deep vein thrombosis. We removed the firmly engorged deep femoral vein on the second operation. We report here on a case of angioleiomyosarcoma that arose from the deep femoral vein.

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.

This study was conducted to determine the effects of deep breathing exercise and ankle exercise on blood flow velocity in the femoral vein. Sixteen healthy male students were recruited from Yonsei University, at Wonju. The blood flow velocities in the femoral vein were measured under three different conditions: resting, deep breathing, and ankle exercise. All subjects were given a 5-minute relaxing time in supine position prior to the study. Using a doppler ultrasound with a 8 MHz probe, the peak blood flow velocities were collected in a twenty-second-period at each condition. The subjects took a rest in between trials for the blood flow to return to its resting levels. The result showed a significant difference in peak blood flow velocities under those three conditions (p<.001). The peak blood flow velocity was highest in ankle exercise condition. The peak blood velocity was significantly higher in deep breathing condition compared with the resting condition. As a result, it is revealed that not only the muscular contractions but also the deep breathing exercises induced facilitating effects of venous return. Either of the exercise methods can be recommended to prevent blood stasis in patients with risk of deep vein thrombosis after cardiac or lower extremity surgery.

During dissection of the saphenofemoral junction, anatomical variations in the tributaries of the long saphenous vein and external pudendal artery are frequently encountered, but the transpositions of the femoral artery and vein have very rarely been reported. On operation of the varicose vein, the surgical complications can be minimized when the possible deviations in the normal anatomy are taken into the consideration.
