Presentation Summary : Deep vein thrombosis diagnostic algorithm. The risks for venous thrombosis are considered immediate (trauma, surgery, temporary immobility); short term (malignancy, pregnancy, severe illness); and long term (multiple prior episodes of thrombosis, acquired and congenital thrombophilic disorders). Cerebrospinal fluid is normally absorbed through arachnoid granulations into the superior sagittal sinus. However, pulmonary embolism can occur with no evidence of DVT. An Overview of Current Concepts of Venous Thrombo-embolism & its Medical Management. A pulmonary embolism (PE) occurs when a clot breaks loose and travels through the bloodstream to the lungs.
