Origin of femoro-popliteal occlusions.

In 1950 Lindbom published the results of a radiological survey of atherosclerotic lesions in 356 legs of 185 cadavers and in 295 arteriograms of 205 patients with arterial insufficiency. He identified two principal sites of origin for femoro-popliteal occlusions, the main one being in the adductor region and the subsidiary in the popliteal artery above the level of the knee-joint. In this survey a similar though simpler and more graphic method has been used to analyse the bilateral femoral arteriograms of a comprehensive group of 264 male patients suffering from intermittent claudication. The information obtained suggests that there are three principal sites of origin of femoropopliteal occlusions, and the relative incidence of occlusion at these sites has been assessed.
