Radiofibrinogen tests were applied to 88 surgical and urological @entity1 with @entity715 of deep veins to establish point and time of @entity715 origin and courses taken by thrombi. Most of the thrombi thus recorded had originated from venous bulges of the @entity291 , the soleus sinus. These accounted for 83 per cent of all thrombi detected. Progress was in all cases in proximal direction, towards the popliteofemoral veins. The intraoperative phase was found to be the most dangerous juncture for the development of thrombi, with 36 per cent of all thrombi emerging on the day of surgery and another 22 per cent on the first and second postoperative days. Prophylaxis against @entity715 , therefore, should be initiated prior to surgical intervention in any case. Bilateral @entity715 was recorded from 22 cases. Sixty-one per cent of all @entity715 were localised on the left side, and 81 per cent of all postoperative @entity715 were clinically latent. There were six non-lethal outbreaks of @entity1151 and one lethal case. While the majority of @entity291 vein @entity715 was relatively harmless, the risk of @entity1151 increased considerably, as thrombi emerged at the level of the popliteal vein. Radioisotope investigation can be used to identify @entity1150 and to figure out those @entity1 in whom @entity1151 or @entity4096 may be expected to develop.
