ABSTRACT
PURPOSE: The purpose of this study was to evaluate the great saphenous vein (GSV) as a conduit for crossover femoro-femoral bypass. Generally the conduit for crossover femoro-femoral bypass is a synthetic material because of the acceptable long-term patency and low complication rates. But, as the average life expectancy becomes extended, a better patency rate becomes more important. In this study, we compared the patency rates and hemodynamic results between crossover femoro-femoral bypass operations with GSVs and those with synthetic grafts. METHODS: From 1998 to 2008, 119 femoro-femoral bypass operations were done. Among them, 38 femoro-femoral bypass used GSV as a conduit (group I) and 79 operations used expanded polytetrafluoroethylene (group II). Two cases used arm veins and we excluded those cases. RESULTS: The 3 year primary patency rate of total cases was 75.1%, 93.7% in group I and 66.1% in group II. There were no statistical differences in hemodynamic results such as peak systolic velocity, volume flow and ankle/brachial systolic pressure index between the two groups. CONCLUSION: The 3 year primary patency rate of group I was better than that of group II. However there were no differences in hemodynamic changes. So GSV is recommended as a conduit for crossover femoro-femoral bypass especially in young patients who are eager to have longer patency rates after surgery instead of less invasive endovascular therapy.

A 45 year-old-women with tracheal stenosis due to an endotracheal tumor was scheduled for tracheal reconstruction surgery. The stenotic lesion was located 1 cm above the carina, and was length of 4 cm and had a narrowest internal diameter of 0.4 cm. The length of such a stenotic segment and its narrowest internal diameter may pose lung ventilation problems before or during tumor resection, which may preclude a successful outcome. Thus, during tracheal reconstruction surgery a femoro-femoral partial cardiopulmonary bypass, self respiration, and pulmonary artery ligation were used. These measures improved oxygenation and cardiovascular stability, and tracheal reconstruction was successfully performed without complication.

In the treatment of aortoiliac disease, two methods could be considered. One is percutaneous transluminal angioplasty, and the other is bypass graft. However sometimes two methods could be combined in high risk patients with a lengthy unilateral occlusion of one iliac artery and less extensive obstruction of the contralateral one, since higher risk aortofemoral bypass surgery may be obviated by femoro-femoral bypass graft after percutaneous treatment of the less diseased iliac artery. We report two cases of arortoiliac disease treated with Strecker stent followed by femoro-femoral bypass graft.
