Piatelets and Vascular Occlusion
There is evidence that aspirin is partially effective in the prophylaxis of various vasoocclusive disorders. This article reviews pharmacologic opportunities for improvement over and above the therapeutic effect of aspirin. It is concluded that several rational possibilities merit consideration, in particular, the use of combinations of drugs that affect the thrombotic process at different poin...
متن کاملPlatelets and Vascular Occlusion
Coronary angiography has proved beyond doubt that complete coronary occlusion is the rule in the very early hours of infarction. The 60% to 80% rate of coronary recanalization after thrombolytic therapy has proved that thrombosis is a major component of the occlusion at the time when the procedure is performed a few hours after the onset of symptoms. However, the trigger for coronary thrombosis...
متن کاملPiatelets and Vascular Occlusion
Selective inhibitors of thromboxane synthase have two theoretical advantages over inhibitors of the cyclooxygenase enzyme as potential antithrombotic compounds. First, they do not prevent formation of prostacyclin, a platelet-inhibitory, vasodilator compound, coincident with inhibiting thromboxane biosynthesis. Second, the prostaglandin endoperoxide substrate that accumulates in the platelet in...
متن کاملThe red blood cell in vascular occlusion.
Red blood cells (RBC) have unique flow-affecting properties--namely, aggregability, deformability and adherence to endothelial cells (EC)--which play major roles in blood flow. Under normal flow-induced shear stress RBC are dispersed, their adherence to EC is insignificant, and they are sufficiently deformable to enable tissue perfusion. However, in pathological conditions that are associated w...
متن کاملIntestinal occlusion caused by endometriosis of the sigmoid colon.
Endometriosis (E) is an estrogen-dependent inflammatory disorder that is observed in approximately 10% of women in childbearing age, and is the most common benign gynecological disorder requiring hospitalization. In 5% of cases, there is an involvement of the gastrointestinal tract, for the most part of the sigmoid colon and rectum (~ 90%). However intestinal obstruction due to severe stenosis ...
