Heart Disease May Be a Risk Factor for Pulmonary Embolism Without Peripheral Deep Venous Thrombosis

Trauma patients often require initial stabilization followed by transfer for ongoing trauma care. Thus, the administration of VTE prophylaxis is often delayed until admission to the receiving hospital. It is unclear if transfer status is a risk factor for VTE. The National Trauma Database v6.2 was used to identify patients admitted to Level I and II trauma centers. Exclusions included patients on anticoagulation, <18 years, known VTE before trauma, or pregnant. Patients transferred were compared with nontransferred patients. Analysis included 736,374 patients with 189,166 (25.69%) transferred patients within 24 hours of injury. Using weighted measures, VTE was identified in 11,619 (1.50%) patients. The VTE rate was significantly higher in the transferred group compared with the nontransferred group (1.73% vs 1.42%, P = 0.002) including deep venous thrombosis (1.39% vs 1.14%, P = 0.004) and pulmonary embolism (0.45% vs 0.39%, P = 0.003). Multivariable analyses adjusting for patient-level risk factors demonstrated that transfer was associated with a higher likelihood of VTE (aOR 1.18; 95% CI: 1.09–1.28, P ≤ 0.001), pulmonary embolism (aOR 1.21; 95% CI: 1.11–1.33, P ≤ 0.001), and deep venous thrombosis (aOR 1.17; 95% CI: 1.07–1.28, P = 0.0004). Transfer status of trauma patients is a risk factor for VTE. Accepting a transferred patient results in an increased VTE risk and may not be reflective of the quality of care at the receiving facility.

Filter Placement ◽

Therapeutic Method

The placement of an inferior vena cava (IVC) filter is a therapeutic method for selected patients with deep venous thrombosis and pulmonary embolism. However, insertion and placement of the filter may be associated with certain complications. For instance, retroperitoneal hematoma resulting from perforation of the wall by the filter is such a very rare but serious complication. We report the case of a 64-year-old woman with perforation of the IVC wall and consecutive hematoma caused by the filter who was treated surgically.

Antiprothrombin Antibodies

SummaryAntibodies against phospholipid-binding plasma proteins, such as β2-glycoprotein I (β2-GPI) and prothrombin, are associated with thromboembolic events in patients with systemic lupus erythematosus and also in subjects with no evident underlying diseases. We wanted to examine whether increased levels of antibodies to negatively-charged phospholipids (cardiolipin), to phospholipid-binding plasma proteins β2-GPI and prothrombin and to oxidised low-density lipoprotein (LDL) were associated with risk of deep venous thrombosis or pulmonary embolism in subjects with no previous thrombosis. The antibodies were measured in stored serum samples from 265 cases of deep venous thrombosis of the lower extremity or pulmonary embolism occurring during a median follow-up of about 7 years and from 265 individually matched controls. The study subjects were middle-aged men participating in a cancer prevention trial of alpha-tocopherol and beta-carotene and the cases of thromboembolic events were identified from nationwide Hospital Discharge Register.The risk for thrombotic events was significantly increased only in relation to antiprothrombin antibodies. As adjusted for body mass index, number of daily cigarettes and history of chronic bronchitis, myocardial infarction and heart failure at baseline, the odds ratio per one unit of antibody was 6.56 (95% confidence interval 1.73-25.0). The seven highest individual optical density-unit values of antiprothrombin antibodies were all confined to subjects with thromboembolic episodes.In conclusion, the present nested case-control study showed that high autoantibody levels against prothrombin implied a risk of deep venous thrombosis and pulmonary embolism and could be involved in the development of the thrombotic processes.

Prothrombin Gene

SummaryA dimorphism in the 3’-untranslated region of the prothrombin gene (G to A transition at position 20210) has recently been reported to be associated with increases in plasma prothrombin levels and in the risk of venous thrombosis (1). We have examined the prothrombin dimorphism among 99 unselected outpatients with phlebography verified deep venous thrombosis, and in 282 healthy controls. The prevalence of the 20210 A allele was 7.1% (7/99) in the patient group, and 1.8% (5/282) in the healthy control group (p = 0.0095). The relative risk of venous thrombosis was calculated to be 4.2 (95% Cl, 1.3 to 13.6), and was still significant when adjustment was made for age, sex and the factor V:R506Q mutation causing APC resistance [odds ratio 3.8 (95% Cl, 1.1 13.2)]. As previously reported, 28% of the patients were carriers of the factor V:R506Q mutation. Thus, 34% (one patient carried both traits) of unselected patients with deep venous thrombosis were carriers of an inherited prothrombotic disorder. To sum up, our results confirm the 20210 A allele of the prothrombin gene to be an important risk factor for venous thrombosis.
