juvenile nasopharyngeal angiofibroma (jna) is a rare, benign and locally invasive tumor. massive bleeding because of vascularity of tumor and postoperative recurrence are potential problems of management. endonasal approach reduces the rate of postoperative recurrence, intraoperative bleeding, and complications of surgery, time of operation and duration of hospitalization. in this article, we r...

The template bleeding time is a measure of platelet participation in primary hemostasis. Aspirin alters platelet function through interference with prostaglandin biosynthesis. In many individuals, aspirin will consistently prolong the bleeding time. Despite this observation, normal individuals rarely develop a bleeding disorder. This prompted us to investigate the influence of technical variabl...

The major side effect of thrombolytic therapy is bleeding; however, the pathogenesis of this potential complication is not well understood. Accordingly, we examined the effects of aspirin and recombinant human tissue-type plasminogen activator (rt-PA) on serial template bleeding times and on hemostasis parameters in rabbits. The administration of intravenous aspirin (15 mg/kg) produced a slight...

BACKGROUND: The relation between the bleeding time, the peripheral veous hematocirt and the amount of blood shed at the template bleeding time site has not been previously defined. METHODS; We studied this relation in 227 individuals: 26 were performed on patients with ITP, 137 on patients with a variety of other bleeding disorders, and 64 in normal subjects. Bleeding times were performed by a ...
