OBJECTIVE To assess the performance of magnetic resonance venography (MRV) for pelvis and deep vein thrombosis in the lower extremities before surgical interventions for varicose veins. MATERIALS AND METHODS We enrolled 72 patients who underwent MRV and ultrasonography before stripping for varicose veins of lower extremities. All images of the deep venous systems were evaluated by time-of-fli...

BACKGROUND Venous ultrasonography identifies reflux patterns of the great and small saphenous veins (GSV, SSV), allowing evaluation of lower extremities for treatment planning and patient follow-up. OBJECTIVE To determine progression of saphenous vein reflux patterns in women with primary venous valvular insufficiency. METHODS Venous ultrasonography was performed in the extremities of 92 wo...

Introduction: Considering importance of fatty acids in developing coronary artery disease (CAD) and lack of information about saphenous vein which is commonly used as coronary arterial bypass, in this study we investigated differences in fatty acids composition between saphenous vein and aorta tissues in patients with CAD. Methods: Biopsy samples of aortic tissues and saphenous veins as well as...

Major peripheral arterial graft infection is a potentially devastating complication of vascular surgery, associated with significant mortality and high amputation rates. Autologous saphenous veins are considered optimal arterial conduits for lower extremity revascularization in infected fields, but they are often unavailable or unsuitable in these patients. This study describes two patients wit...

OBJECTIVES Vein graft disease is a major drawback of coronary artery bypass grafting. However, histopathologic studies of old human aortocoronary grafts are scarce. METHODS We screened patients undergoing redo coronary artery bypass grafting at three university hospitals and selected those with at least one excisable old vein graft. Native non-grafted saphenous veins were also obtained as con...

PURPOSE We aimed to assess hemodynamic changes in calf perforator veins (PVs) after endovenous laser ablation (EVLA) of saphenous veins. METHODS The series comprised 60 limbs of 41 patients (27 female, 14 male; median age, 43 years [range, 22-78 years]) who underwent EVLA for varicose veins. All patients were prospectively evaluated by means of color Doppler ultrasonography before and after t...

BACKGROUND In mice, 18F-fluorodeoxyglucose (18F-FDG) positron-emission tomography/computed tomography (PET/CT) lymphography enables detailed imaging of the lymphatic system and quantification of lymph node function. If this applies to humans, it may improve staging of several malignancies. The aim of this study was to elucidate whether foot skin depots of 18F-FDG make PET/CT imaging of the lowe...

PURPOSE To investigate if noradrenaline (NA) and 5-hydroxyptamine (5-HT) drugs induce responses of isolated control and varicose veins are altered by removal of the endothelium. SUBJECTS #ENTITYSTARTX00026; METHODS Specimens of the great saphenous vein (GSV) were obtained from 12 subjects with primary varicose veins and 12 subjects from donor vessels at cardiac surgery. A total of 10 normal h...
