Risk factors for deep venous thrombosis of the upper extremities

Article Abstract:

Muscle exertion but not blood clotting factor levels seems to be a significant risk factor for developing deep blood clots in the arms. Blood chemistry was compared among 36 patients with deep arm blood clots, 121 patients with deep leg blood clots, and 108 healthy volunteers (control group). One third of the patients with arm clots had recently exercised the affected arm. Clotting rates and anticlotting factor and homocysteine levels were similar for patients with arm clots and the control group but lower than for patients with leg clots. Only patients with leg clots carried antiphospholipid antibodies.

Cost of long-term complications of deep venous thrombosis of the lower extremities: an analysis of a defined patient population in Sweden

Article Abstract:

Deep vein thrombosis appears to lead to costly complications whose economic impact could be reduced by preventing the condition. Deep vein thrombosis is characterized by the formation of blood clots in the major veins of the legs. In a 15-year study of 257 patients with deep vein thrombosis and 241 healthy people (the control group), the cost of treating complications of thrombosis amounted to $4,659. Complications included varicose veins, leg ulcers and pulmonary embolism, which occurs when the blood clot travels to the lungs. The cost of treating these conditions in the control group totaled $375.

Ultrasonographic screening before hospital discharge for deep venous thrombosis after arthroplasty: the Post-Arthroplasty Screening Study: a randomized, controlled trial

Article Abstract:

Using a screening procedure called compression ultrasonography to identify joint-surgery patients who develop blood clots but have no symptoms may have little value. Of 1,024 patients who received an artificial knee or hip, 518 were screened after the operation with compression ultrasonography and 506 were not. In both groups, about 1% of the patients were found to have asymptomatic blood clots. All of the patients began taking the anticoagulant drug warfarin the night before surgery and continued taking it until they were discharged. This probably led to the low incidence of blood clots.
