Arterial embolism is usually caused by cardiac disease, and atherosclerotic coronary vascular disease is the primary precursor. Other cardiac states, as well as several uncommon causes, are part of the etiologic spectrum. The earliest signs are pain, paresthesias, pallor, and pulselessness. Severe ischemia is indicated by paralysis, a late feature. Arterial embolism and acute thrombosis can be difficult to distinguish, and deep venous thrombosis may also be suspected in the differential diagnosis. To restore arterial flow, anticoagulation treatment with heparin (Lipo-Hepin, Liquaemin) is given and surgical embolectomy is performed. Heparin infusion is continued until the patient is ambulatory, and then warfarin sodium (Coumadin, Panwarfin) is given over the long term. Fibrinolysis has also been used to treat acute arterial occlusion. Complications of embolism must be carefully guarded against, and additional procedures are sometimes necessary.

Acute arterial occlusions of the extremities present with the classical five P's: pain, pallor, pulselessness, paresthesia, paresis. Loss of sensitivity and motility are symptoms of the most severe grade of ischemia. The occlusions are due to embolism in about 70% of subjects and to local thrombosis in 30%. These patients have to be treated immediately with heparin. In the mildest forms, deobliteration is desirable, but in the more severe cases rapid restoration of flow not only saves limbs but also life. Deobliteration may be performed surgically or by means of catheters (local thrombolysis or thrombus aspiration) if available. Deep vein thrombosis, the other kind of emergency situation, requires immediate anticoagulation as soon as pulmonary embolism is suspected. It should be initiated by heparin and followed by oral anticoagulation. In patients presenting without pulmonary embolism but a swollen leg, ruptured Baker cysts or muscle hematomas should be ruled out before anticoagulation is started. Systemic thrombolysis or surgical thrombectomy is reserved for young patients with acute isolated thromboses. Thrombectomy must also be kept in reserve for the most severe form of deep venous thromboses, the phlegmasia cerulea dolens. In thrombophlebitis, no anticoagulation is indicated except in bedridden patients. The others must remain mobile and may be treated by systemic and local antiinflammatory drugs, incision of thrombosed varices, and bandages.

Thrombotic complications in acute leukemia are often underestimated because bleeding complications generally dominate the clinical picture. While there are many thrombogenic factors shared by both solid tumors and leukemia, many additional prothrombotic features are present in leukemia. The prothrombotic factors include hyperleukocytosis, increased expression of tissue factor and its activation in leukemic cells, and the prothrombotic adverse effects of therapeutic agents and vascular access cathethers. A 18-year old woman came with swelling on her right leg 10 days before hospital admission. Since 2 months before she had had weakness, pallor and fever without bleeding manifestation. Hematologic examinations showed anemia, leukocytosis with monoblast and thrombocytopenia. Deep vein thrombosis in right femoral and right popliteal vein was confirmed using compression ultrasonography. The treatment of such complications is challenging because of the high risk of hemorrhage in this group of patients, especially due to their severe thrombocytopenia.
