In patients undergoing knee arthroscopy, prophylactic LMWH for 1 week reduced a composite end point of asymptomatic proximal deep venous thrombosis, symptomatic venous thromboembolism, and all-cause mortality more than did graduated compression stockings.

The rate of pulmonary embolism in patients with thrombophlebitis of the greater saphenous vein is unexpectedly high. This risk is similarly high in patients with thrombosis at the saphenofemoral junction and in patients without thrombosis at the saphenofemoral junction. Our results are consistent with those of other recent investigations and suggest that superficial thrombophlebitis of the thigh is not as benign a disease entity as previously described.

ICA occlusion seems to represent a relatively benign condition, in both its symptomatic and asymptomatic presentation. The presence of an atherosclerotic stenosis less than 75% of the contralateral ICA does not seem to worsen the prognosis of this condition.

Spontaneous recanalization of previously occluded extracranial ICAs is more frequent than anticipated. Once it occurs, spontaneous recanalization seems to have a benign long-term course.
